  • Using bindings to control column order in a DataGrid

    - by DanM
    Problem I have a WPF Toolkit DataGrid, and I'd like to be able to switch among several preset column orders. This is an MVVM project, so the column orders are stored in a ViewModel. The problem is, I can't get bindings to work for the DisplayIndex property. No matter what I try, including the sweet method in this Josh Smith tutorial, I get: The DisplayIndex for the DataGridColumn with Header 'ID' is out of range. DisplayIndex must be greater than or equal to 0 and less than Columns.Count. Parameter name: displayIndex. Actual value was -1. Is there any workaround for this? I'm including my test code below. Please let me know if you see any problems with it. ViewModel code public class MainViewModel { public List<Plan> Plans { get; set; } public int IdDisplayIndex { get; set; } public int NameDisplayIndex { get; set; } public int DescriptionDisplayIndex { get; set; } public MainViewModel() { Initialize(); } private void Initialize() { IdDisplayIndex = 1; NameDisplayIndex = 2; DescriptionDisplayIndex = 0; Plans = new List<Plan> { new Plan { Id = 1, Name = "Primary", Description = "Likely to work." }, new Plan { Id = 2, Name = "Plan B", Description = "Backup plan." }, new Plan { Id = 3, Name = "Plan C", Description = "Last resort." } }; } } Plan Class public class Plan { public int Id { get; set; } public string Name { get; set; } public string Description { get; set; } } Window code - this uses Josh Smith's DataContextSpy <Window x:Class="WpfApplication1.MainWindow" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:local="clr-namespace:WpfApplication1" xmlns:mwc="http://schemas.microsoft.com/wpf/2008/toolkit" Title="Main Window" Height="300" Width="300"> <Grid> <mwc:DataGrid ItemsSource="{Binding Plans}" AutoGenerateColumns="False"> <mwc:DataGrid.Resources> <local:DataContextSpy x:Key="spy" /> </mwc:DataGrid.Resources> <mwc:DataGrid.Columns> <mwc:DataGridTextColumn Header="ID" Binding="{Binding Id}" DisplayIndex="{Binding Source={StaticResource spy}, Path=DataContext.IdDisplayIndex}" /> <mwc:DataGridTextColumn Header="Name" Binding="{Binding Name}" DisplayIndex="{Binding Source={StaticResource spy}, Path=DataContext.NameDisplayIndex}" /> <mwc:DataGridTextColumn Header="Description" Binding="{Binding Description}" DisplayIndex="{Binding Source={StaticResource spy}, Path=DataContext.DescriptionDisplayIndex}" /> </mwc:DataGrid.Columns> </mwc:DataGrid> </Grid> </Window> Note: If I just use plain numbers for DisplayIndex, everything works fine, so the problem is definitely with the bindings. Update 5/1/2010 I was just doing a little maintenance on my project, and I noticed that when I ran it, the problem I discuss in this post had returned. I knew that it worked last time I ran it, so I eventually narrowed the problem down to the fact that I had installed a newer version of the WPF Toolkit (Feb '10). When I reverted to the June '09 version, everything worked fine again. So, I'm now doing something I should have done in this first place: I'm including the WPFToolkit.dll that works in my solution folder and checking it into version control. It's unfortunate, though, that the newer toolkit has a breaking change.

  • Is there a way to edit a control's template based on the default template?

    - by Adam S
    I'm trying to make just a few minor tweaks to the default template of a checkbox. Now I understand how to make a new template from scratch, but this I do not know. I did manage to (I think?) extract the default template via the method here. And it spat out: <ControlTemplate TargetType="CheckBox" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:s="clr-namespace:System;assembly=mscorlib" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:mwt="clr-namespace:Microsoft.Windows.Themes;assembly=PresentationFramework.Luna"> <BulletDecorator Background="#00FFFFFF" SnapsToDevicePixels="True"> <BulletDecorator.Bullet> <mwt:BulletChrome Background="{TemplateBinding Panel.Background}" BorderBrush="{TemplateBinding Border.BorderBrush}" BorderThickness="{TemplateBinding Border.BorderThickness}" RenderMouseOver="{TemplateBinding UIElement.IsMouseOver}" RenderPressed="{TemplateBinding ButtonBase.IsPressed}" IsChecked="{TemplateBinding ToggleButton.IsChecked}" /> </BulletDecorator.Bullet> <ContentPresenter RecognizesAccessKey="True" Content="{TemplateBinding ContentControl.Content}" ContentTemplate="{TemplateBinding ContentControl.ContentTemplate}" ContentStringFormat="{TemplateBinding ContentControl.ContentStringFormat}" Margin="{TemplateBinding Control.Padding}" HorizontalAlignment="{TemplateBinding Control.HorizontalContentAlignment}" VerticalAlignment="{TemplateBinding Control.VerticalContentAlignment}" SnapsToDevicePixels="{TemplateBinding UIElement.SnapsToDevicePixels}" /> </BulletDecorator> <ControlTemplate.Triggers> <Trigger Property="ContentControl.HasContent"> <Setter Property="FrameworkElement.FocusVisualStyle"> <Setter.Value> <Style TargetType="IFrameworkInputElement"> <Style.Resources> <ResourceDictionary /> </Style.Resources> <Setter Property="Control.Template"> <Setter.Value> <ControlTemplate> <Rectangle Stroke="#FF000000" StrokeThickness="1" StrokeDashArray="1 2" Margin="14,0,0,0" SnapsToDevicePixels="True" /> </ControlTemplate> </Setter.Value> </Setter> </Style> </Setter.Value> </Setter> <Setter Property="Control.Padding"> <Setter.Value> <Thickness>2,0,0,0</Thickness> </Setter.Value> </Setter> <Trigger.Value> <s:Boolean>True</s:Boolean> </Trigger.Value> </Trigger> <Trigger Property="UIElement.IsEnabled"> <Setter Property="TextElement.Foreground"> <Setter.Value> <DynamicResource ResourceKey="{x:Static SystemColors.GrayTextBrushKey}" /> </Setter.Value> </Setter> <Trigger.Value> <s:Boolean>False</s:Boolean> </Trigger.Value> </Trigger> </ControlTemplate.Triggers> </ControlTemplate> Okay, sure, looks just fine I guess. I don't have enough experience to know if that looks like it's right or not. Now, I get two errors: Assembly 'PresentationFramework.Luna' was not found. Verify that you are not missing an assembly reference. Also, verify that your project and all referenced assemblies have been built. and The type 'mwt:BulletChrome' was not found. Verify that you are not missing an assembly reference and that all referenced assemblies have been built. Now I'm wondering, how can I resolve these errors so that I can actually start working on the template? Is there a better way of going about this? My boss wants a three-state checkbox with a red square instead of green, and he won't take no for an answer.

  • Google Chrome app file opened is not always in front, receiving focus

    - by Philipp Lenssen
    On Windows Vista, I'm launching files associated with a Google Chrome "Application Shortcut" app by double-clicking them. While they will always open this way, they will sometimes not receive focus -- i.e. they sit in the task bar quietly but don't actually show in front on the screen (until I click on the app in the task bar again). Does anyone know how I can force the just-opened app to receive focus? The app being opened actually contains a web app I can customize, so I also have access to performing JavaScript commands post-startup. For background information, here is the regedit file I originally used to create the file association. Might well be this is a Google Chrome internal issue... apps I open with other editors get their focus alright, AFAIK. Thanks!

  • Win XP Virtual Machine APP that won't START as a terminal services client

    - by Daniel
    I have a Win XP Virtual Machine APP that won't START as a terminal services client..... but if i disable terminal services inside the virtual machine, start the app then start terminal services... the APP runs fine (so long as terminal services are disabled when it starts.....!) My question is... is it possible to script things somehow so as to allow this app to be accessed directly from win 7 (with out having to manually run XP virtual machine)... I.E as I can not run it this way as it won't START with terminal services running.... I.e is it somehow possible to script things so the APP starts and terminal services is delayed then kicks in after a time delay.... (I know this may not be possible but I'm getting sick of all the mucking around...)

  • Set a custom favicon locally, that carries across the entire site.

    - by Iszi
    Is there a way to add a custom favicon to an App Tab? In the above thread, @admintech links to a great plugin for changing favicons which covers both the bookmarks folder and the address bar/tab bar icons. However, it still does not quite fully address what I was hoping to accomplish. I'd like to set an App Tab that has a customized icon, that stays the same in that tab no matter what I do there. Since the navigation within an App Tab is very restricted, the chosen favicon should always be relevant to whatever page is loaded in that tab. The Bookmark Favicon Changer has been effective in allowing me to use a custom favicon in the App Tab. But, the favicon only applies to the specific URL that was bookmarked. Any navigation done from that page will return the favicon to blank. Is there another plugin, or perhaps some special tweak to this plugin or the bookmark itself, that will allow me to make the favicon more persistent across the site?

  • Can only access asp.net app on localhost

    - by Kevin Donn
    I'm trying to get an asp.net application up on IIS on a Windows Server 2008 machine. I can hit the app from localhost, no problem. But I can't access the app using the server's domain name either locally or from another machine on the network. But here's the odd part. I can access a normal file on IIS using the domain name, both from a browser running on the server and from a browser running on another machine on the network. Here's a synopsis ("http" converted to "htp" below because I don't have enough points to have all these links in my message): From IE on the server itself: works htp://localhost/foo.htm works htp://localhost/App works htp://test.foo.com/foo.htm dead htp://test.foo.com/App From IE on another machine (inside or outside my subnet): works htp://test.foo.com/foo.htm dead htp://test.foo.com/App And when I say "dead" I mean the request times out. Any ideas?

  • cannot at all find sql instance (while installing an asp.net app on IIS)

    - by giddy
    So I'm really not a DBA, I'm an app dev. I had to install my asp.net mvc3 app on my client's(a large company) IIS6 + Win2k3 machine, with absolutely no help from their sysadmins. The final problem now is SQL Server 2008 r2, after figuring out how to create a login from windows, my app and sqlcmd.exe always complains it cannot find a sql server instance!! I have all the sql services (in services.msc) running to Log On as the local system. I can login fine with SQL Server Management Studio with Windows Auth. I created my database, my asp.net app needs/uses windows auth. But for the love of God, whatever I do my app always complains it cannot find the instance. (Also tried running SQL CMD and it complains of the same thing too!) My data base connection string looks like this: Data Source=machinename\username;Initial Catalog=myDataStore;Integrated Security=True;MultipleActiveResultSets=True Machinename\user is the same thing that shows up on the sql server management studio login if I choose windows authentication right?

  • How do you protect your <appid>.appspot.com domain from DDOS attack?

    - by jacob
    If I want to use CloudFlare to help protect my GAE app via it's custom domain, I still am vulnerable to attacks directly on the .appspot.com domain. How do I mitigate that? I could force redirect appspot.com host requests, such as discussed here: http://stackoverflow.com/questions/1364733/block-requests-from-appspot-com-and-force-custom-domain-in-google-app-engine/ But I would still suffer the load of processing the redirect in my app. Are there any other solutions?

  • WPF Canvas Binding

    - by morsanu
    Hey guys, I'm rather new to WPF, so maybe this is a simple question. I have a class that derives from Canvas, let's call it MyCanvas. And I have a class, MyClass, that has a property of type MyCanvas. In XAML, I built a TabControl, so each TabItem binds to a MyClass object. Now, in the Content of every tab I want to display MyObject.MyCanvas. How should I do that? <TabControl.ContentTemplate> <DataTemplate> <Grid> <myCanvas:MyCanvas Focusable="true" Margin="10" > <Binding Path="Canvas"></Binding> </screenCanvas:ScreenCanvas> </Grid> </DataTemplate> </TabControl.ContentTemplate>

  • wpf binding by selected value - swap out bound object without disturbing binding

    - by Andy Clarke
    Hi, I've got combo box bound to a custom collection type - its basically an overridden ObservableCollection which I've added a facility to update the underlying collection (via Unity). I don't want to confuse the issue too much, but thats the background. My xaml looks like this <ComboBox ItemsSource="{Binding Manufacturers}" DisplayMemberPath="Name" SelectedValuePath="ID" SelectedValue="{Binding Vehicle.ManufacturerID}" /> And in my overridden collection i was doing this. index = IndexOf(oldItem); Insert(index, (T)newItem); RemoveAt(index + 1); I had hoped because it was bound by value, that inserting the new object(which had the same id) and then removing the old one would work. But it seems that although its bound by SelectedValue it still knows that its being swapped for a different one. The combo just looses its selection. Can anyone help please?

  • FlowDocument contents as text

    - by tyndall
    What is the best way to get back the XAML/XML value of a FlowDocument? I noticed there isn't a .Value, .Text, .Caption, .ToXml(), etc... UDPATE: I'd like to be able to get access to it initially to serialize to disk or database. Treat it as its own document format. Later translating it to other formats would be nice. Also been wondering: Any equivalent to a hyperlink (opens in new browser window) in a FlowDocument? Any workaround?

  • WinRT GridView scrolling setup work differently on mouse/kb and touch

    - by Jay Kannan
    I'm trying to mimic the functionality of the NetFlix app, with a strip on the left that collapses on scrolling, I had to offset the tiles on the GridView a bit to the right so that they can accomodate that behavior. They seem to work alright in keyboard and scroll completely to the right (although I noticed the scrollbar suddenly grows in size when I hit the left boundaries. this totally changes when I use it on touch - I seem to have a limit on the right and the scrolling doesnt scroll past the last 100 pixels or so. how do I take care of this. I'm assuming it is related to the bug here, but didn't seem to solve the problem with that solution there. "Sticky scrolling" issue in WinRT XAML GridView control

  • Is it possible to make customizable WPF styles?

    - by Dheeraj Kumar
    I really like WPF because of its awesome skinning support by changing resourcedictionaries on the fly, but the catch is, the styles must be made by designers in XAML. My client needs a skinnable UI where the end users can make skins themselves. My question is - In Photoshop, you can take any image, and add a color overlay to change all the colors to that hue. Can you do something similar in WPF? I'm just a beginner, and looking at several WPF styles, it seems like all the color values are hard-coded. Here's a sample scenario - user selects two colors from color pickers, and all the controls have a gradient background from Color1 to Color2.

  • Is there any event fired when a DataTemplate has been initiated in WPF?

    - by Shimmy
    Hello! Take a look at the following xaml: <ListBox ItemsSource="{Binding}"> <ListBox.Resources> <CollectionViewSource x:Key="CVS"/> </ListBox.Resources> <ListBox.DataTemplate> <DataTemplate OnBinding="myBinding"> <ListBox DataContext="{StaticResource CVS}" ItemsSource="{Binding}" /> </DataTemplate> </ListBox.DataTemplate> </ListBox> So I can handle the binding and manually retrieve the CVS and set its Source property to my custom stuff according to the DataTemplate's DataContext. Or else there is a different way in doing it. Any ideas are welcommed!

  • WPF tabcontrol styling

    - by BrettRobi
    I've got a UI with a fairly standard look and feel. It has a column of icons on the left side which when clicked open a different user control on the right side. Currently I'm using separate controls for the selection icons and the usercontrol containment. I'm having strange focus issues that I am tired of trying to mitigate and am wondering if I could style a tabcontrol to look like my UI (under the assumption a tabcontrol would not have focus issues when navigating tabs). Here is a screenshot of the basic UI. The styling is mostly about how to get the tabcontrols page selection to look like my column of icons. Anyone want to throw their hat in the ring as to how I might accomplish this with a tabcontrol? My xaml is pretty weak at this point.
