  • Value of text box disapears - binding viewmodel to a tab (content control)

    - by Eli Perpinyal
    Based on the MVVM example by Josh Smith, I have implemented the multi tab option which binds to a different tab to a different view model using a simple datatemplate that binds a viewmodel to a view. <DataTemplate DataType="{x:Type fixtureVM:SearchViewModel}"> <SearchVw:SearchView/> </DataTemplate> The issue that I'm having, is when I switch tabs and then switch back again, the value in the textbox disappears. When I bind the Text in the textbox to a value in the ViewModel it does not disappear. This is fine, and I can overcome this but I am having another issue for example with the position of the scroll bar in a grid disappearing once the tab has lost focus. Why is the value disappearing? I'm assuming it is a WPF sub system task that cleans up resources!? how can I avoid this? I also feel it might be slowing down my app.

  • Control third check box based on the state of the first two using jquery

    - by Moj
    I have three check boxes and need to disable the third if either and/or of the other two are checked. I'm sure there's a easier way than what I have currently. It's turning into what I believe is a mess and I'm hoping that someone with more jquery knowledge can shine the light here. Here's my simple html form: <html> <head> <script type="text/javascript" src="jquery.js"></script> <script src="custom.js" type="text/javascript"></script> </head> <body> <input type="checkbox" class="class" id="1">First <input type="checkbox" class="class" id="2">Second <input type="checkbox" class="class" id="3">Third </body> </html> Here's the javascript I'm using with jquery v1.4.2 jQuery(document).ready(function() { // watches the events of all checkboxes $(":checkbox").click(function(){ if( // if both 1 and 2 are checked we don't want to enable Third until both are unchecked. (($('#1:checkbox').attr('checked'))&&($('#2:checkbox').attr('checked')))|| ((($('#1:checkbox').attr('checked'))&&($('#2:checkbox').attr('checked')))&&($('#3:checkbox').attr('disabled')))|| ((($('#1:checkbox').attr('checked'))||($('#2:checkbox').attr('checked')))&&($('#3:checkbox').attr('disabled'))) ){ // we don't want to do anything in the above events } else if( // handles the First check box (($('#1:checkbox').attr('checked'))||(!$('#1:checkbox').attr('checked')))|| // handles the Second check box (($('#2:checkbox').attr('checked'))||(!$('#2:checkbox').attr('checked'))) ){ // call the disableThird function disableThird(); } }); // handles enabling and disabling the Third checkbox function disableThird(){ var $checkbox = $('#3:checkbox'); $checkbox.attr('disabled', !$checkbox.attr('disabled')); }; }); For some reason checking #3 will disable it's self. I don't understand why. This works, but one of the requirements is that a non programmer should be able to edit and maintain this. Ideally it'd be great if he could just add new check boxes to the html and it would work. The class for these are define and as far as I know can't be changed. The last check box in the list of check boxes will disable if any of the ones above are selected. Like wise if the last check box is selected, it will disable all the ones above it. I haven't even begun writing and testing that portion as this is quickly becoming too complicated for a non programmer to handle. I myself am more of a PHP coder than a js, let alone jquery, coder. Any help would be greatly appreciated.

  • UIWebView Page Control

    - by Jack
    Hi, I would like to use a UIWebView to display some files (PDF, PPT, DOC) and would like to have the ability to scroll using external controls (ie a couple of buttons that, when pressed skip back and forward a page) and display the current page in a UITextView. Is this possible? I have no experience with javascript, but a friend of mine has suggested that this might be a useful approach. Is his suggestion valid? JP

  • A control that contains multiple duplicate properties causing deadlock issues on IIS

    - by heads5150
    I am trying to work out if the above case is true for our site. I've been told by my hosting provider that this fix (http://support.microsoft.com/kb/974165) has to applied to our server due to performance issues. It basically describes an issues where UI code like: <asp:gridview id="GridView1" runat="server" ... PageSize="100" PagerSettings-Mode="Numeric" PagerStyle-BorderStyle="None" PagerStyle-BorderColor="Navy" PagerStyle-HorizontalAlign="Right" PagerSettings-PageButtonCount="2" PagerSettings-Position="Bottom"> <PagerStyle HorizontalAlign="Left" BorderColor="Navy" BorderStyle="None"></PagerStyle> ... <PagerSettings PageButtonCount="2"></PagerSettings> ... </asp:gridview> causing the following warning on the server "ISAPI 'C:\Windows\Microsoft.NET\Framework\v2.0.50727\aspnet_isapi.dll' reported itself as unhealthy for the following reason: 'Deadlock detected'." Does anybody know of a way that I can detect this issue in the build process or the debugger? Any help would be much appreciate.

  • JQuery Ajax control

    - by Anycolor
    Everybody hi. There is a problem with my own AJAX library, that I can't solve. I have some block (#ajax-loading), that has events: $('#ajax-loading') .bind('ajaxStart', function() { $('#ajax-loading').show(); }) .bind('ajaxStop', function() { $('#ajax-loading').fadeOut(150); }); For running AJAX I have special method: run: function(data, callback) { if(this.request) { this.request.abort(); } this.request = $.getJSON(window.location.pathname, data , callback); }, So .request holds current AJAX request. What do I want? My #ajax-loading block contains the button, than should Cancel current AJAX request. As I supposed, the function, making Cancel shoud contain: abort: function() { if(ajax.request) { this.request.abort(); $('#ajax-loading').fadeOut(150); } } But, as I said, there is a problem: my AJAX request cancels, loading-block hides, but when another request starts, this block doesn't shows again. It seems that when I abort AJAX request, the ajaxStop event doesn't happen. And when I run new request ajaxStart doesn't happen. I think it can be connected with readyState or status field of XMLHttpRequest, or smth similar. Could anyone help me with this or explain what's wrong. PS: excuse my english, it's not my native language...

  • Rendering a control generates security exception in .Net 4

    - by Jason Short
    I am having a problem with code that worked fine in .Net 2 giving this error under .Net 4. Build (web): Inheritance security rules violated while overriding member: 'Controls.RelatedPosts.RenderControl(System.Web.UI.HtmlTextWriter)'. Security accessibility of the overriding method must match the security accessibility of the method being overriden. This is in DotNetBlogEngine. There were several other security demands in the code that .Net 4 didn't seem to like. I followed some of the advice I found on blogs (and here) and got rid of all the other errors. But this one still eludes me. The Main blogengine core dll is not set for security demands anylonger and is compiled for .Net 4 as well. This error is in the website side attempting to use the dll. There are controls that call a RenderControl method taking an HtmlTextWriter. Apparently the text writer now has some soft of security attributes set on it. Each of the controls implements a custom interface ( public interface ICustomFilter ), there are no security permissions present or demands. The site is running full trust on my local dev machine.

  • Visual Studio Team System 2008 - messy formatting/control characters/marks in source code

    - by AL
    Hi, I don't know what I did but somehow the IDE has started displaying a green dot whenever I press spacebar and a green arrowhead whenever I press TAB. The source has become littered with these characters all over and I am finding it very difficult to code in the presence of so many formatting marks. I have tried to search a solution on Google but couldn't perhaps enter the right keywords so haven't been able to fix the behavior. Is there any way I can stop VS2008 IDE from littering my source code with these green dots and arrowheads whenever I press spacebar/tab? I would be really thankful for this help. Thanks, -AL

  • Configuring Cruise Control Net with sourcesafe - Unable to load array item 'executable'

    - by albert
    Hi all, I'm trying to create a continuous integration environment. To do so, I've used a guide that can be found at http://www.15seconds.com/issue/040621.htm. In this step by step, the goal is to create a CI with CCNet, NAnt, NUni, NDoc, FxCop and source safe. I've been able to create my build by using the command prompt (despite the the different versions issues). The problem has come with the configuration of ccnet.config I've made some changes because of the new versions, but I'm still getting errors when starting the CCNet server. Can anyone help me to fix this issue or point where to find a guide with this scenario? The error that I'm getting: Unable to instantiate CruiseControl projects from configuration document. Configuration document is likely missing Xml nodes required for properly populating CruiseControl configuration. Unable to load array item 'executable' - Cannot convert from type System.String to ThoughtWorks.CruiseControl.Core.ITask for object with value: "\DevTools\nant\bin\NAnt.exe" Xml: E:\DevTools\nant\bin\NAnt.exe My CCNet config file below: <cruisecontrol> <project name="BuildingSolution"> <webURL>http://localhost/ccnet</webURL> <modificationDelaySeconds>10</modificationDelaySeconds> <triggers> <intervaltrigger name="continuous" seconds="60" /> </triggers> <sourcecontrol type="vss" autoGetSource="true"> <ssdir>E:\VSS\</ssdir> <executable>C:\Program Files\Microsoft Visual SourceSafe\SS.EXE</executable> <project>$/CCNet/slnCCNet.root/slnCCNet</project> <username>Albert</username> <password></password> </sourcecontrol> <prebuild type="nant"> <executable>E:\DevTools\nant\bin\NAnt.exe</executable> <buildFile>E:\Builds\buildingsolution\WebForm.build</buildFile> <logger>NAnt.Core.XmlLogger</logger> <buildTimeoutSeconds>300</buildTimeoutSeconds> </prebuild> <tasks> <nant> <executable>E:\DevTools\nant\bin\nant.exe</executable> <nologo>true</nologo> <buildFile>E:\Builds\buildingsolution\WebForm.build</buildFile> <logger>NAnt.Core.XmlLogger</logger> <targetList> <target>build</target> </targetList> <buildTimeoutSeconds>6000</buildTimeoutSeconds> </nant> </tasks> <publishers> <merge> <files> <file>E:\Builds\buildingsolution\latest\*-results.xml</file> </files> </merge> <xmllogger /> </publishers> </project> </cruisecontrol> enter code here

  • MVVM: how to set the datacontext of a user control

    - by EVA
    Hi, I'm writing an application in WPF, using the MVVm toolkit and have problems with hooking up the viewmodel and view. The model is created with ado.net entity framework. The viewmodel: public class CustomerViewModel { private Models.Customer customer; //constructor private ObservableCollection<Models.Customer> _customer = new ObservableCollection<Models.Customer>(); public ObservableCollection<Models.Customer> AllCustomers { get { return _customer; } } private Models.Customer _selectedItem; public Models.Customer SelectedItem { get { return _selectedItem; } } public void LoadCustomers() { List<Models.Customer> list = DataAccessLayer.getcustomers(); foreach (Models.Customer customer in list) { this._customer.Add(customer); } } } And the view (no code behind at the moment): <UserControl x:Class="Customers.Customer" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" xmlns:d="http://schemas.microsoft.com/expression/blend/2008" mc:Ignorable="d" xmlns:vm ="clr-namespace:Customers.ViewModels" d:DesignHeight="300" d:DesignWidth="300" xmlns:toolkit="http://schemas.microsoft.com/wpf/2008/toolkit" > <Grid> <toolkit:DataGrid ItemsSource="{Binding AllCustomers}" SelectedItem="{Binding SelectedItem, Mode=TwoWay}" AutoGenerateColumns="True"> </toolkit:DataGrid> <toolkit:DataGrid ItemsSource="{Binding SelectedItem.Orders}"> </toolkit:DataGrid> </Grid> </UserControl> And dataaccesslayer class: class DataAccessLayer { public List<Customer> customers = new List<Customer>(); public static List<Customer> getcustomers() { entities db = new entities(); var customers = from c in db.Customer.Include("Orders") select c; return customers.ToList(); } } The problem is that no data is displayed simply because the data context is not set. I tried to do it in a code-behind but is did not work. I would prefer to do it in a xaml file anyway. Another problem is with the SelectedItem binding - the code is never used. Thanks for help! Regards, EV.

  • How to use WatiN to control browser tabs?

    - by Dmitri Nesteruk
    I want to use WatiN with IE in a parallel setting, i.e. work with dozens/hundreds of pages at once. I've tried sticking it into a Parallel.For loop only to see the whole thing crash, so I'm thinking opening multiple tabs in the browser is the way to go. Can someone suggest how this can be done using WatiN (or just some IE-related API) or whether there's a better way? TIA!

  • Does Shoes have a list view control?

    I was taking a look at Shoes which seems like a very nice tool for quick GUI applications. The common elements/controls, however, don't seem to include the equivalent of a list/report view (e.g., ListView in Windows, NSTableView in OS X). Did I just miss this, or does it not (yet) exist?
