• How to bind a WPF CustomControl to a ListBox

  - by VivyG

  I've just started to learn WPF this week so please accept my apologies if I am being stupid or missing fundamental points! Iam trying to build a very simple Contact browser. I have a Collection of Contact objects that displayed in a ListBox control which shows the FullName of the Contact and to the right I have a customControl called BasicContactCard. This is the XAML for the ContacWindow that displays the ListBox: <DockPanel Width="auto" Height="auto" Margin="8 8 8 8"> <Border Height="56" HorizontalAlignment="Stretch" VerticalAlignment="Top" BorderThickness="1" CornerRadius="8" DockPanel.Dock="Top" Background="Beige"> <TextBox Height="32" Margin="23,5,135,5" Text="Search for contact here" FontStyle="Italic" Foreground="#FFAD9595" FontSize="14" BorderBrush="LightGray"/> </Border> <ListBox x:Name="contactList" DockPanel.Dock="Left" Width="192" Height="auto" Margin="5 4 0 8" /> <Grid> <Grid.RowDefinitions> <RowDefinition Height="1*" /> <RowDefinition Height="0.125*" /> </Grid.RowDefinitions> <local:BasicContactCard Margin="8 8 8 8" /> <Button Grid.Row="1" x:Name="exit" Content="Exit" HorizontalAlignment="Right" Width="50" Height="25" Click="exit_Click" /> </Grid> </DockPanel> and this is the XAML for the CustomControl: <DockPanel Width="auto " Height="auto" Margin="8,8,8,8"> <Grid Width="auto" Height="auto" DockPanel.Dock="Top"> <Grid.RowDefinitions> <RowDefinition Height="1*" /> <RowDefinition Height="1*" /> <RowDefinition Height="1*" /> <RowDefinition Height="1*" /> </Grid.RowDefinitions> <TextBlock x:Name="companyField" Grid.Row="0" Width="auto" HorizontalAlignment="Stretch" VerticalAlignment="Stretch" Margin="8,8,8,8" Text="Company"/> <TextBlock x:Name="contactField" Grid.Row="1" Width="auto" HorizontalAlignment="Stretch" VerticalAlignment="Stretch" Margin="8,8,8,8" Text="Contact"/> <TextBlock x:Name="phoneField" Grid.Row="2" Width="auto" HorizontalAlignment="Stretch" VerticalAlignment="Stretch" Margin="8,8,8,8" Text="Phone"/> <TextBlock x:Name="emailField" Grid.Row="3" Width="auto" HorizontalAlignment="Stretch" VerticalAlignment="Stretch" Margin="8,8,8,8" Text="email"/> </Grid> </DockPanel> The problem I have is how do I bind the individual elements of the CustomControl to the object behind the SelectedItem in the ListBox?

  - by JonH

  Hello folks I've got a class that pulls model information (hardware info) for a local machine code is like so: Imports System.Management Public Class clsWMI Private objOS As ManagementObjectSearcher Private objCS As ManagementObjectSearcher Private objMgmt As ManagementObject Private m_strComputerName As String Private m_strManufacturer As String Private m_StrModel As String Private m_strOSName As String Private m_strOSVersion As String Private m_strSystemType As String Private m_strTPM As String Private m_strWindowsDir As String Public Sub New() objOS = New ManagementObjectSearcher("SELECT * FROM Win32_OperatingSystem") objCS = New ManagementObjectSearcher("SELECT * FROM Win32_ComputerSystem") For Each objMgmt In objOS.Get m_strOSName = objMgmt("name").ToString() m_strOSVersion = objMgmt("version").ToString() m_strComputerName = objMgmt("csname").ToString() m_strWindowsDir = objMgmt("windowsdirectory").ToString() Next For Each objMgmt In objCS.Get m_strManufacturer = objMgmt("manufacturer").ToString() m_StrModel = objMgmt("model").ToString() m_strSystemType = objMgmt("systemtype").ToString m_strTPM = objMgmt("totalphysicalmemory").ToString() Next End Sub Public ReadOnly Property ComputerName() Get ComputerName = m_strComputerName End Get End Property Public ReadOnly Property Manufacturer() Get Manufacturer = m_strManufacturer End Get End Property Public ReadOnly Property Model() Get Model = m_StrModel End Get End Property Public ReadOnly Property OsName() Get OsName = m_strOSName End Get End Property Public ReadOnly Property OSVersion() Get OSVersion = m_strOSVersion End Get End Property Public ReadOnly Property SystemType() Get SystemType = m_strSystemType End Get End Property Public ReadOnly Property TotalPhysicalMemory() Get TotalPhysicalMemory = m_strTPM End Get End Property Public ReadOnly Property WindowsDirectory() Get WindowsDirectory = m_strWindowsDir End Get End Property End Class Any possibility to get a service tag from WMI ?

• Adding lengths of strings together in Ruby

  - by ppreyer

  I'm trying to write a program that takes the length of my first, middle, and last names individually and then adds the total amount of letters up in the end. My answer keeps on being 666 instead of 18. Here is the code I have written: puts 'What is your first name?' firstName = gets.chomp realFirstName = firstName.length.to_i puts 'What is your middle name?' middleName = gets.chomp realMiddleName = middleName.length.to_i puts 'What is your last name?' lastName = gets.chomp realLastName = lastName.length.to_i puts 'Did you know there are ' + realFirstName.to_s + realMiddleName.to_s + realLastName.to_s + ' letters in your name?' Just wondering where I went wrong.

• Comparing multiple entity properties against list of entities

  - by roosteronacid

  Consider this snippet of code: var iList = new List<Entities.Ingredient> { new Entities.Ingredient { Name = "tomato", Amount = 2.0 }, new Entities.Ingredient { Name = "cheese", Amount = 100.0 } }; var matches = new DataContext().Ingredients.Where(i => Comparer(i, iList)); private Boolean Comparer(Entities.Ingredient i, List<Entities.Ingredient> iList) { foreach (var i in iList) { if (i.Name == iList.Name && i.Amount >= iList.Amount) return true; } return false; } Is there a more efficient way of doing this? Preferably without being too verbose; from x in y select z... If thats at all possible.

• Objective C: Create arrays from first array based on value

  - by Nic Hubbard

  I have an array of strings that are comma separated such as: Steve Jobs,12,CA Fake Name,21,CA Test Name,22,CA Bill Gates,44,WA Bill Nye,21,OR I have those values in an NSScanner object so that I can loop through the values and get each comma seperated value using objectAtIndex. So, what I would like to do, is group the array items into new arrays, based on a value, in this case, State. So, from those, I need to loop through, checking which state they are in, and push those into a new array, one array per state. CA Array: Steve Jobs,12,CA Fake Name,21,CA Test Name,22,CA WA Array: Bill Gates,44,WA OR Array: Bill Nye,21,OR So in the end, I would have 3 new arrays, one for each state. Also, if there were additional states used in the first array, those should have new arrays created also. Any help would be appreciated!

• Render a Form from an XSLT file

  - by Russ Clark

  I've generated the following XSLT file, and have created a Form that will post to an ASP.Net MVC action called Home/ProcessRequest: <?xml version="1.0" encoding="utf-8"?> <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:msxsl="urn:schemas-microsoft-com:xslt" exclude-result-prefixes="msxsl" > <xsl:output method="html" indent="yes"/> <xsl:template match="/"> <html> <body> <xsl:value-of select="Employee/Name"/> <br /> <xsl:value-of select="Employee/ID"/> <form method="post" action="/Home/ProcessRequest?id=42"> <input id="Action" name="Action" type="radio" value="Approved"></input> Approved <br /> <input id="Action" name="Action" type="radio" value="Rejected"></input> Rejected <br /> <input type="submit" value="Submit"></input> </form> </body> </html> Here is my XML File: <Employee xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema"> <Name>Russ</Name> <ID>42</ID> </Employee> This works fine the way it is, but I need to change the id parameter in my from from a hard coded integer, to use the ID element from my XML file. Does anyone know how to do this?

• Why does xdebug crash apache on every XAMPP install I've tried?

  - by Ian Cook

  I've installed the Windows XAMPP package on three separate computers, 2 running Windows Vista 32 bit ( 1 Ultimate / 1 Home Premium ) and 1 running Windows Vista 64 Home Premium. After enabling xdebug in php.ini and restarting apache, viewing the default XAMPP localhost index causes apache to crash in the same way every time, reporting 'php_xdebug.dll' as the Fault Module Name. Here's the full report from the Windows Crash Reporter thing: Problem signature: Problem Event Name: APPCRASH Application Name: apache.exe Application Version: 2.2.9.0 Application Timestamp: 4853f994 Fault Module Name: php_xdebug.dll Fault Module Version: 2.0.3.0 Fault Module Timestamp: 47fcd9b9 Exception Code: c0000005 Exception Offset: 00008493 OS Version: 6.0.6001.2.1.0.768.3 Locale ID: 1033 Additional Information 1: a34a Additional Information 2: c9c5f4fd744690d388ab9d5b3eb051a7 Additional Information 3: cb2e Additional Information 4: 650bb5690556a17e911375b94d3e16f0 I've tried Googling this issue but haven't found any resolution, only reports of similar errors. EDIT: I enabled the extension line for php_xdebug.dll and that seems to have stopped the crashing so far.

• NAnt not running NUnit tests

  - by ctford

  I'm using NUnit 2.5 and NAnt 0.85 to compile a .NET 3.5 library. Because NAnt 0.85 doesn't support .NET 3.5 out of the box, I've added an entry for the 3.5 framework to NAnt.exe.config. 'MyLibrary' builds, but when I hit the "test" target to execute the NUnit tests, none of them seem to run. [nunit2] Tests run: 0, Failures: 0, Not run: 0, Time: 0.012 seconds Here are the entries in my NAnt.build file for the building and running the tests: <target name="build_tests" depends="build_core"> <mkdir dir="Target" /> <csc target="library" output="Target\Test.dll" debug="true"> <references> <include name="Target\MyLibrary.dll"/> <include name="Libraries\nunit.framework.dll"/> </references> <sources> <include name="Test\**\*.cs" /> </sources> </csc> </target> <target name="test" depends="build_tests"> <nunit2> <formatter type="Plain" /> <test assemblyname="Target\Test.dll" /> </nunit2> </target> Is there some versioning issue I need to be aware of? Test.dll runs fine in the NUnit GUI. The testing dll is definitely being found, because if I move it I get the following error: Failure executing test(s). If you assembly is not build using NUnit 2.2.8.0... Could not load file or assembly 'Test' or one of its dependencies... I would be grateful if anyone could point me in the right direction or describe a similary situation they have encountered. Edit I have since tried it with NAnt 0.86 beta 1, and the same problem occurs.

• VSTS test deployment and invalid assembly culture

  - by Merlyn Morgan-Graham

  I have a DLL that I'm testing, which links to a DLL that has what I think is an invalid value for AssemblyCulture. The value is "Neutral" (notice the upper-case "N"), whereas the DLL I'm testing, and every other DLL in my project, has a value of "neutral" (because they specify AssemblyCulture("")). When I try to deploy the DLL that links to the problem DLL, I get this error in VSTS: Failed to queue test run '...': Culture is not supported. Parameter name: name Neutral is an invalid culture identifier. <Exception>System.Globalization.CultureNotFoundException: Culture is not supported. Parameter name: name Neutral is an invalid culture identifier. at System.Globalization.CultureInfo..ctor(String name, Boolean useUserOverride) at System.Globalization.CultureInfo..ctor(String name) at System.Reflection.RuntimeAssembly.GetReferencedAssemblies(RuntimeAssembly assembly) at System.Reflection.RuntimeAssembly.GetReferencedAssemblies() at Microsoft.VisualStudio.TestTools.Utility.AssemblyLoadWorker.ProcessChildren(Assembly assembly) at Microsoft.VisualStudio.TestTools.Utility.AssemblyLoadWorker.GetDependentAssemblies(String path) at Microsoft.VisualStudio.TestTools.Utility.AssemblyLoadWorker.GetDependentAssemblies(String path) at Microsoft.VisualStudio.TestTools.Utility.AssemblyLoadStrategy.GetDependentAssemblies(String path) at Microsoft.VisualStudio.TestTools.Utility.AssemblyHelper.GetDependentAssemblies(String path, DependentAssemblyOptions options, String configFile) at Microsoft.VisualStudio.TestTools.TestManagement.DeploymentManager.GetDependencies(String master, String configFile, TestRunConfiguration runConfig, DeploymentItemOrigin dependencyOrigin, List`1 dependencyDeploymentItems, Dictionary`2 missingDependentAssemblies) at Microsoft.VisualStudio.TestTools.TestManagement.DeploymentManager.DoDeployment(TestRun run, FileCopyService fileCopyService) at Microsoft.VisualStudio.TestTools.TestManagement.ControllerProxy.SetupTestRun(TestRun run, Boolean isNewTestRun, FileCopyService fileCopyService, DeploymentManager deploymentManager) at Microsoft.VisualStudio.TestTools.TestManagement.ControllerProxy.SetupRunAndListener(TestRun run, FileCopyService fileCopyService, DeploymentManager deploymentManager) at Microsoft.VisualStudio.TestTools.TestManagement.ControllerProxy.QueueTestRunWorker(Object state)</Exception> Even if I don't link to the DLL (in my VSTS wrapper test, or in the NUnit test), as soon as I add it in my GenericTest file (I'm wrapping NUnit tests), I get that exception. We don't have the source for the problem DLL, and it is also code signed, so I can't solve this by recompiling. Is there a way to skip deploying the dependencies of a DLL DeploymentItem, to fix or disable the culture check, or to work around this by convoluted means (maybe somehow embed the assembly)? Is there a way to override the value for the culture, short of hacking the DLL (and removing code signing so the hack works)? Maybe with an external manifest? Any correct solution must work without weird changes to production code. We can't deploy a hacked DLL, for example. It also must allow the DLL to be instrumented for code coverage. Additional note: I do get a linker warning when compiling the DLL under test that links to the problem DLL, but this hasn't broken anything but VSTS, and multiple versions have shipped.

• Flash video playing on top of everything else in IE7

  - by Brett

  Hi everyone, I've been spending hours now reading up on IE7's issue with rendering Flash content on top of other elements, particularly navigation menus (this is often a problem with dropdown menus and Flash ad banners, for example). I've tried a few of the suggested solutions but none have worked for me so far. I'll do my best to explain the circumstances, and would appreciate any advice in the matter! Update At Mercator's request, I am providing a large code-sample to assist in any advice you might have. Consider the HTML below: <body> <div id="page-wrap"> <div id="content-wrap"> <div id="main"> <h1>Page Title</h1> <p>Paragraph text before video.</p> <div class="video-container"> <script type="text/javascript"> AC_FL_RunContent('id','player','name','player','width','480','height','294','src','player','allowscriptaccess','always','allowfullscreen','true','flashvars','file=mp4/VIDEO_FILE.mp4','movie','player' ); //end AC code </script> <noscript> <object id="player" classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000" name="player" width="480" height="294"> <param name="wmode" value="transparent" /> <param name="movie" value="player.swf" /> <param name="allowfullscreen" value="true" /> <param name="allowscriptaccess" value="always" /> <param name="flashvars" value="file=mp4/VIDEO_FILE.mp4" /> <embed wmode="transparent" type="application/x-shockwave-flash" id="player2" name="player2" src="player.swf" width="480" height="294" allowscriptaccess="always" allowfullscreen="true" flashvars="file=mp4/VIDEO_FILE.mp4" ></embed> </object> </noscript> </div> <p>Paragraph after video.</p> </div><!-- end main --> <div id="subContent"> <p>Sub-content.</p> </div><!-- end subContent --> <div id="content-clear"></div> </div><!-- end content-wrap --> </div><!-- end page-wrap --> <div id="footpanel"> <ul id="mainpanel"> <li id="panel-link"><a href="#"><span class="icon"></span>Panel Link</a> <div class="subpanel"> <h3><span> &ndash; </span>Panel Link</h3> <ul> <li><p>Revealed content</p></li> </ul> </div> </li> </ul> </div> <!-- END footpanel --> </body> Below are the non-presentational CSS selectors that apply to the divs above: body { /*no positioning styles applied */ } #page-wrap { width: 100%; } #content-wrap { width: 960px; margin 0 auto; } #main { float: left; width: 573px; } .video-container { position: relative; width: 480px; z-index: 1; } #sub { float: left; width: 347px; } #content-clear { clear: both; } #foot-panel { position: fixed; width: 94%; bottom: 0; left: 0; z-index: 3000; } ul#main-panel { float: left; } The footpanel uses jQuery-powered flyout menus, if that provides any further context. These menus have z-indexes in the 300X range to appear above the footpanel. The Flash in question is JW player playing a flash video or mp4. Currently, the object and embed tags are inside a container div. My understanding of previous solutions was that the combination of the param changes and the positioning/z-index change on the container div should have resolved the issue. Alas, it is not so. The player resides on top of the footpanel. Other information that may or may not be helpful is that the page is XHTML 1.0 Transitional and that Dreamweaver reports 1 error in the HTML code: <embed> is not in the XHTML 1.0 specification. This fact does not prevent the video from being viewed in any browser tested, and the page still displays correctly in FF. Thanks in advance!

• How do I sort a multidimensional hash array by a key maybe three levels in, in PHP?

  - by Chris Denman

  I am moving from Perl to PHP and am struggling to get my head around PHP sorting. Here's what I have in Perl: $log{12345}{0}{20100102}{name}='blah'; $log{54312}{1}{20100101}{name}='blah'; $log{14323}{3}{20100103}{name}='blah'; foreach $entry (sort {$log{$cook}{$a}{time} cmp $log{$cook}{$b}{time}} keys %{$log{$cook}}){ ... } Basically, I would have the same array structure in PHP but want to sort like I do above.

• Caching a column in a polymorphic relationship

  - by Brendon Muir

  I have content management system application that uses a polymorphic tree table as the core of its arrangement. I've come into a problem where once the tree grows quite large, and because we have quite a few different modules (about 25), just doing :include = :instance doesn't cut the mustard. Instance is the name of our polymorphic relationship. The funny part is that in most cases when I want a large list of these items, all I really want is their name from the associated table (for the purposes of an index bar for example), all the rest is in the central table. So I thought that I should probably implement some sort of column cache for the name in the central table. (Like a counter cache that rails already does). I was just wondering if a plugin exists to manage this already? If not, I was just going to add a 'name' column to the central table and because all the polymorphic models inherit off a superclass, just add a callback that pushes the name across to the central table whenever the item is created or updated. I'd then just do a big migration to populate it in the first place? Any flaws to that design? I suppose to be more flexible the column could be some kind of serialised cache where I could store other things later on if need be? Gah! :D

• How to upload a file with watir and IE?

  - by karlthorwald

  I am writing a watir script to test an upload form. But the script does not automatically choose the file that is to be uploaded from my harddrive. Instead IE stops with the file chooser dialog open. As soon as I manually select the to be uploaded file in the dialog and click ok, watir continues as desired. I wonder why it stops. This is from my watir script: ie.file_field(:name, 'upload').set("s:\\localwatir\\Test_Pdf.pdf") ie.button(:name, 'submit').click I got the code from this page: http://wiki.openqa.org/display/WTR/File+Uploads This is the form: <form name="form1" enctype="multipart/form-data" method="post" action="uploadlegacy.php"> <input type="file" name="upload" size="30"> <input type="submit" name="submit" value="upload"> </form> I have found this manual http://svn.openqa.org/svn/watir/trunk/watir/unittests/filefield_test.rb also, but as I do not know what $htmlRoot stands for, I cannot really follow it. Does that mean, I have to put some "file///" into the parameter for set()? If so, how exactly? I am using IE 6 for the testing.

• jQuery Autocomplete Json Ajax cross browser issue with Google Search Appliance

  - by skyfoot

  I am implementing a jquery autocomplete on a search form and am getting the suggestions from the Google Search Appliance Autocomple suggestions service which returns a result set in json. What I am trying to do is go off to the GSA to get suggestions when the user types something in the search box. The url to get the json suggestions is as follows: http://gsaurl/suggest?q=<query>&max=10&site=default_site&client=default_frontend&access=p&format=rich The json which is returned is as follows: { "query":"re", "results": [ {"name":"red", "type":"suggest"}, {"name":"read", "type":"suggest"}] } The jQuery autocomplete code is as follows: $(#q).autocomplete(searchUrl, { width: 320, dataType: 'json', highlight: false, scroll: true, scrollHeight: 300, parse: function(data) { var array = new Array(); for(var i=0;i<data.results.length;i++) { array[i] = { data: data.results[i], value: data.results[i].name, result: data.results[i].name }; } return array; }, formatItem: function(row) { return row.name; } }); This works in IE but fails in firefox as the data returned in the parse function is null. Any ideas why this would be the case? Workaround I created an aspx page to call the GSA suggest service and to return the json from the suggest service. Using this page as a proxy and setting it as the url in the jQuery autocomplete worked in both IE and FireFox.

• ExtJS combo setting problem

  - by Hubidubi

  Hi I run into an interesting problem while was using combos in input form. My form contains combos that get data from json stores. It works fine when adding new record, but when the form is opened for editing an existing record, sometimes the id appears as selected not its value (eg: there's 5 instead of "apple"). I think it tries to set the value before it finishes loading the combo. Is there a way to solve this? I put the code down here that creates combos: function dictComboMaker( store, fieldLabel, hiddenName, name, allowBlank, myToolTipp ) { comboo = { xtype : 'combo', id: 'id-'+name, allowBlank: allowBlank, fieldLabel : fieldLabel, forceSelection : true, displayField : 'value', valueField : 'id', editable: false, name: name, hiddenName : hiddenName, minChars : 2, mode: 'remote', triggerAction : 'all', store : store }; function dictJsonMaker(url) { store = new Ext.data.JsonStore({ root : 'results', // 1 fields : [ 'id','value' ], url : url, autoLoad: true}); return store; } var comboKarStore = dictJsonMaker('/service/karok'); var comboKar= dictComboMaker(comboKarStore, 'Kar', 'karid', 'kar', false, ''); // then comboKar is added to the form Hubidubi

• How Do I Bind a "selected Item" in a Listbox to a ItemsControl in WPF?

  - by Scott

  LowDown: I am trying to create a Document Viewer in WPF. It will allow the user to preview selected documents and if they want, compare the documents in WPF. So they can view them side by side. The layout is this: Left side is a full list box. On the right side is a Collection or an Items control. Inside the items control will be a collection of the "selected documents" in the list box. So A user can select multiple items in the list box and for each new item they select, they can add the item to the collection on the right. I want the collection to look like a image gallery that shows up in Google/Bing Image searches. Make sense? The problem I am having is I can't get the WPFPreviewer to bind correctly to the selected item in the list box under the itemscontrol. Side Note: The WPFPreviewer is something Micorosft puts out that allows us to preview documents. Other previewers can be built for all types of documents, but im going basic here until I get this working right. I have been successful in binding to the list box WITHOUT the items control here: <Window.Resources> <DataTemplate x:Key="listBoxTemplate"> <StackPanel Margin="3" > <DockPanel > <Image Source="{Binding IconURL}" Height="30"></Image> <TextBlock Text=" " /> <TextBlock x:Name="Title" Text="{Binding Title}" FontWeight="Bold" /> <TextBlock x:Name="URL" Visibility="Collapsed" Text="{Binding Url}"/> </DockPanel> </StackPanel> </DataTemplate> </Window.Resources> <Grid Background="Cyan"> <ListBox HorizontalAlignment="Left" ItemTemplate="{StaticResource listBoxTemplate}" Width="200" AllowDrop="True" x:Name="lbDocuments" ItemsSource="{Binding Path=DocumentElements,ElementName=winDocument}" DragEnter="documentListBox_DragEnter" /> <l:WPFPreviewHandler Content="{Binding ElementName=lbDocuments, Path=SelectedItem.Url}"/> </Grid> Though, once I add in the ItemsControl, I can't get it to work anymore: <Window.Resources> <DataTemplate x:Key="listBoxTemplate"> <StackPanel Margin="3" > <DockPanel > <Image Source="{Binding IconURL}" Height="30"></Image> <TextBlock Text=" " /> <TextBlock x:Name="Title" Text="{Binding Title}" FontWeight="Bold" /> <TextBlock x:Name="URL" Visibility="Collapsed" Text="{Binding Url}"/> </DockPanel> </StackPanel> </DataTemplate> </Window.Resources> <Grid> <ListBox HorizontalAlignment="Left" ItemTemplate="{StaticResource listBoxTemplate}" Width="200" AllowDrop="True" x:Name="lbDocuments" ItemsSource="{Binding Path=DocumentElements,ElementName=winDocument}" DragEnter="documentListBox_DragEnter" /> <ItemsControl x:Name="DocumentViewer" ItemsSource="{Binding ElementName=lbDocuments, Path=SelectedItem.Url}" > <ItemsControl.ItemTemplate> <DataTemplate> <Grid Background="Cyan"> <l:WPFPreviewHandler Content="{Binding Url}"/> </Grid> </DataTemplate> </ItemsControl.ItemTemplate> </ItemsControl> </Grid> Can someone please help me out with trying to bind to the ItemsControl if I select one or even multiple items in the listbox.

• jQGrid is not loading data

  - by user324777

  Hi, I am using jqGrid for my data table solution. Below are the configuration codes. $(function() { $("#submitInput").click(function() { alert("I am called...") jQuery("#list").jqGrid({ datatype: "json", url: "http://localhost:1201/admin/someURL.htm", mtype:"POST", height: "auto", colNames:["Column 1", "Column 2", "Column 3", "Column 4", "Column 5"], colModel:[ {name:"col1", index:"col1", sortable:true, resizable:false}, {name:"col2", index:"col2", sortable:true}, {name:"col3", index:"col3", sortable:false, resizable:false}, {name:"col4", index:"col4", sortable:true, resizable:false}, {name:"col5", index:"col5", sortable:true, resizable:false} ], sortname:'col1', sortorder:'asc', pager: $('#pager'), rowNum:10, viewrecords: true, rowList:[10,20,30], caption: 'Some Grid Values', jsonReader: { root: "responseData", page: "currentPage", total: "totalPages", records: "totalFetchedRecords", repeatitems: true, cell: "rowContent", id: "rowID" }, gridComplete: function() { alert("Loading done..."); } }); }); }); My JSON data is coming in following format: "currentPage":"1","responseData":[ {"rowContent":["Col1_Val_000001","Col2_Val_1","Col3_Val_1","Col4_Val_1","Col5_Val_1"],"rowID":"Col1_Val_000001"}, {"rowContent":["Col1_Val_000002","Col2_Val_2","Col3_Val_2","Col4_Val_2","Col5_Val_2"],"rowID":"Col1_Val_000002"} ], "totalFetchedRecords":"50","totalPages":"5"} In my HTML, there is a button with id "submitInput" and a table with id "list". Somehow, this data is not loaded into the grid. Please provide some help. Thanks, Niranjan

• Zend: How to populate data to checkboxes?

  - by NAVEED

  I am working on zend. I have a form with some checkboxes. I want to get data from database and populate this data to this form. If '1' is stored in table field then tick the check box otherwise leave it alone. In textboxes and dropdowns, data is easily populated but how to check a checkbox in action. I am creating checkboxes and textboxes elements like this in form.php: // Person name $person = $this->CreateElement('text', 'name'); $person->setLabel('Name'); $elements[] = $person; // Organization name $person = $this->CreateElement('text', 'organization'); $person->setLabel('Organization'); $elements[] = $person; // isAdmin Checkbox $isAdmin = $this->CreateElement('checkbox', 'isAdmin'); $isAdmin->setLabel('Admin'); $elements[] = $isAdmin; $this->addElements($elements); $this->setElementDecorators(array('ViewHelper')); // set form decorator (what script will render the form) $this->setDecorators(array(array('ViewScript' , array('viewScript' => 'organization/accessroles-form.phtml')))); And populating data like this (for example): // Prepare data to populate $data['name'] = 'Naveed'; $data['organization'] = 'ABC'; $data['isAdmin'] = '1'; // Populate editable data $this->view->form->populate( $data ); It is populating data in textboxes but not checking the checkbox? Any idea that how to check a checkbox from action? Thanks

• Multiselect Form Field in PDF

  - by Jason R. Coombs

  Using PDF, is it possible to create a single form element with multiple fields of which several can be selected? For example, in HTML, one can create a set of checkboxes associated with the same field name: <div>Select one for Member of the School Board</div> <input type="checkbox" name="field(school)" value="vote1"> <span class="label">Libby T. Garvey</span><br/> <input type="checkbox" name="field(school)" value="vote2"> <span class="label">Emma N. Violand-Sanchez</span><br/> In this case, the field name is "field(school)", and when the form is submitted, "field(school)" can be supplied 0, 1, or 2 times. Is there an equivalent construct in PDF where a single field can have multiple values. So far in my investigation, it appears that if fields are assigned the same name, it is only possible to select one field. If it is possible to implement this in PDF, what is this construct called and how can it be implemented? Edit: To clarify, I am aware that a PDF can contain multiple form fields with different field names, and those can be selected independently, but then the grouping is implicit and not explicit as with the HTML form. I would like to use a construct that makes the grouping of options explicit, and preferably allows for restrictions (e.g. at least one required, no more than 2 allowed, etc).
