  • Show Hint Tip of a truncated WPF ListBox Item

    - by vbnc141
    Hi, Been searching all over but could not find the answer I am looking for; perhaps I'm not using the correct search term. Anyways, my question is whether there is a property on the WPF ListBox control which I can set that will automatically display the full text of a truncated list item into a Hint Tip? For example, with some WinForm list-container controls, the Hint Tip only appears when the mouse is hovered over a list item that is truncated.

  • Changing the style of a Combo-Box in WPF (in Blend preferably)

    - by George Sealy
    I'm having some issues trying to change the look / style of a combo box in Expression Blend / WPF. While there are tutorials out there describing setting styles for buttons, there seem to be a few wrinkles with ComboBox controls. Can anyone offer any advice, or point me towards good tutorials that cover re-styling something more complex than a button?

  • Easy way to use Images in WPF

    - by j-t-s
    Hi All I've only just started using WPF. (I'm a WinForms guy), and from what I can see, trying to simply drag an image onto the Window is a huge PAIN. There seems to be no way where you can just select an option to tell it what picture to put indide the image control. I've seen so many sites within the last 10 minutes with atleast 10lines of code just to insert animage into a window. Is there an easier way?

  • WPF: change binding properties for multiple controls

    - by Catalin DICU
    I'd like that all the Text bindings for the TextBoxes in my UserControl to have UpdateSourceTrigger=PropertyChanged, and ValidatesOnDataErrors=True How to do it ? I can think of a solution: use another class for bindings (a class inheriting Binding) but maybe there is another solution, maybe using a style or template ?

  • How to define a default tooltip style for all Controls

    - by skjagini
    I would like to define a style with a template when there are validation errors and would display the first error message as a tooltip. It works fine when targeting specific control like DatePicker in the following xaml. <Style TargetType="{x:Type ToolKit:DatePicker}"> <Style.Triggers> <Trigger Property="Validation.HasError" Value="true"> <Setter Property="ToolTip" Value="{Binding RelativeSource={RelativeSource Self}, Path=(Validation.Errors)[0].ErrorContent}"/> </Trigger> </Style.Triggers> </Style> I cannot get it to work for Control though, i.e. the following doesn't give any tooltip <Style TargetType="{x:Type ToolKit:Control}"> <Style.Triggers> <Trigger Property="Validation.HasError" Value="true"> <Setter Property="ToolTip" Value="{Binding RelativeSource={RelativeSource Self}, Path=(Validation.Errors)[0].ErrorContent}"/> </Trigger> </Style.Triggers> </Style> Any idea?

  • Master Detail same View binding controls

    - by pipelinecache
    Hi everyone, say I have a List View with ItemControls. And a Details part that shows the selected Item from List View. Both are in the same xaml page. I tried everything to accomplish it, but what do I miss? <!-- // List --> <ItemsControl ItemsSource="{Binding Path=Model, ElementName=SomeListViewControl, Mode=Default}" SnapsToDevicePixels="True" Focusable="False" IsTabStop="False"> <ItemsControl.ItemTemplate> <DataTemplate> <SomeListView:SomeListItemControl x:Name=listItem/> </DataTemplate> </ItemsControl.ItemTemplate> </ItemsControl> <!-- // Details --> <Label Content="Begindatum" FontSize="16" VerticalAlignment="Center" Grid.Row="1" Margin="2,0,0,0"/> <TextBox x:Name="Begindatum" Grid.Column="1" Grid.Row="1" Text="{Binding Path=BeginDate, ElementName=listItem,Converter={StaticResource DateTimeConverter}, ConverterParameter=dd-MM-yyyy}" IsEnabled="False" Style="{DynamicResource TextBoxStyle}" MaxLength="30"/> public event EventHandler<DataEventArgs<SomeEntity>> OnOpenSomething; public ObservableCollection<SomeEntity> Model { get { return (ObservableCollection<SomeEntity>)GetValue(ModelProperty); } set { Model.CollectionChanged -= new NotifyCollectionChangedEventHandler(Model_CollectionChanged); SetValue(ModelProperty, value); Model.CollectionChanged += new NotifyCollectionChangedEventHandler(Model_CollectionChanged); UpdateVisualState(); } } public static readonly DependencyProperty ModelProperty = DependencyProperty.Register("Model", typeof(ObservableCollection<SomeEntity>), typeof(SomeListView), new UIPropertyMetadata(new ObservableCollection<SomeEntity>(), new PropertyChangedCallback(ChangedModel))); private static void ChangedModel(DependencyObject source, DependencyPropertyChangedEventArgs e) { SomeListView someListView = source as SomeListView; if (someListView.Model == null) { return; } CollectionView cv = (CollectionView)CollectionViewSource.GetDefaultView(someListView.Model); } private void Model_CollectionChanged(object sender, NotifyCollectionChangedEventArgs e) { if (Model == null) { return; } }

  • Inheriting System.Windows.Controls.Panel

    - by modosansreves
    I use the Panel to provide custom layout of UIElements. For this, I override MeasureOverride and ArrangeOverride. In ArrangeOverride proper locations are given to Children. In my application, there is a bunch of rather heavy (by number of visuals) children inside the panel, but only 2 of them are located inside the visible region at a time. Working with my application I feel like all the visuals are drown. I need to introduce a kind of 'virtualization' and make the children render (or take CPU cycles) selectively. How do I?

  • Binding ListBox to List (Collection) in XAML

    - by david2tm
    Hello, I'm learning WPF, so I'm kind of n00b in this. I saw some examples about how to do what I want to do, but nothing exactly... The question: I want to bind List to ListBox. I want to do it in XAML, w/o coding in code behind. How can I achieve that? Right now I do it that way: <!-- XAML --> <ListBox x:Name="FileList"> <ListBox.ItemTemplate> <DataTemplate> <Label Content="{Binding Path=.}"/> </DataTemplate> </ListBox.ItemTemplate> </ListBox> // Code behind public MainWindow() { // ... files = new List<string>(); FileList.ItemsSource = files; } private void FolderBrowser_TextChanged(object sender, RoutedEventArgs e) { string folder = FolderBrowser.Text; files.Clear(); files.AddRange(Directory.GetFiles(folder, "*.txt", SearchOption.AllDirectories)); FileList.Items.Refresh(); } But I want to get rid of FileList.ItemsSource = files; and FileList.Items.Refresh(); in C# code. Thanks

  • Can't access resource from Generic.xaml within the Custom Control constructor.

  • Is there a user-comfortable Unix-like OS?

    - by Rob Kam
    Apparently BSD is like this but only for the OS not for the third party applications: Is there a Unix or Unix-like operating system (but not OS X), where all the installed applications and drivers either all work smoothly/properly or are not included in the distribution? But not something that's been dumbed down.

  • Local User & Local Admin User Server 2008

    - by Ammo
    Hi I had a test recently and one of the questions was to create a file and local user and give the local user write permission to that file. I created the local user successfully however when I went to add permission to the file it would not find the local user when name was entered correctly, and idea what could have prevented this. Secondly I was asked to create a local admin account and give full permissions to the file, to my knowledge server 2008 has a built in admin account, and neither was the server a domain controller. Could you tell me what you would do in this situation? Many Thanks!

  • C#/WPF - RoutedEvent in WPF class that isn't a UIElement

    - by Andreas
    I have a class that needs to notify that something significant has occured. The class is in a WPF-project, even though this specific class, is lookless (and doesn't inherit from UIElement, neither directly or indirectly). Normally, I just register a RoutedEvent to get this functionality but as this class neither has AddHandler nor RemoveHandler, I can't get it to work. Anyone knows of another way of get the RoutedEvent behaviour?

  • Extending DataGrid/Changing DataGrids header

    - by drasto
    Is there any way how to override DataGrids header line ? Or at least its behaviour ? I'm trying to implement Outlook-like grouping of the table. That is allow user to drag column header out of the table to the dedicated area to sort by that column (for example XamDataGrid has that feature, you can see how it works here). I cannot use any commercial solutions. I will be thankfull for any experiences, ideas, code, notes or tutorials.

  • WPF 3D - converting from Point2D to Point3D and back again

    - by DanM
    I'm new to WPF 3D, so I may just be missing something obvious, but how would I go about converting from a 2D coordinate to a 3D coordinate and back again? I'd like the 2D coordinate to be the location measured from the upper-left corner of Viewport3D and the 3D coordinate to be the location relative to the origin (0, 0, 0) of the 3D world. The conversion functions should have these signatures: public Point3D Point2DAndWorldZToPoint3D(Point2D point2D, double worldZ) // usually I want to know where a 2D point will be on the ground plane // so worldZ will usually be zero (but not always) public Point2D Point3DToPoint2D(Point3D point3D) I found this related question, but it only addresses conversion from 3D to 2D (not the reverse), and I'm not sure if the answers are up-to-date. Note, I'm currently using .NET 3.5, but if there are improvements in .NET 4.0 that would help me, please let me know.

  • WPF Window Style not working at runtime

    - by Christian Pena
    Hi, I created a WPF application in Visual Studio 2010 Express (C#) and added the text below to the Application.Resources in App.xaml. I see the style applied to the window in the designer, but when I run the application, the window background is white. Running in Windows XP on BootCamp on a MacBook Pro if that is a factor. Thanks in advance, Christian <Style TargetType="{x:Type Window}"> <Setter Property="Background"> <Setter.Value> <LinearGradientBrush StartPoint="0,0" EndPoint="0,1"> <GradientStop Offset="0" Color="WhiteSmoke" /> <GradientStop Offset="1" Color="Silver" /> </LinearGradientBrush> </Setter.Value> </Setter> <Setter Property="Padding" Value="20" /> </Style>

  • WPF 3D - Need help writing conversion methods between 2D and 3D (Point3DToPoint and PointAndZToPoint

    - by DanM
    I'm new to WPF 3D, so I may just be missing something obvious, but how do I convert from 3D to 2D and (for a given z location) from 2D to 3D? Specifically, I need two conversion methods: Point3DToPoint - If I have an (x, y, z) coordinate in the 3D world, how do I determine the (x, y) coordinate on the projected 2D surface. Method signature: public Point Point3DToPoint(Point3D point3D) PointAndZToPoint3D - If I have an (x, y) coordinate on the projected 2D surface and a z location in the 3D world, how do I determine the intersecting (x, y, z) coordinate in the 3D world? Method signature: public Point3D PointAndZToPoint3D(Point point, double z) I'd like the 2D coordinate to be the location measured from the upper-left corner of Viewport3D and the 3D coordinate to be the location relative to the origin (0, 0, 0) of the 3D world. Note 1: I found this related question, but it only addresses conversion from 3D to 2D (not the reverse), and I'm not sure if the answers are up-to-date.

  • How to Animate a Gradient on a Path to visualize data flow in WPF/WCF app

    - by John
    I have an interesting project where several "nodes" on a cnavas are connected via a Path similiar to a mindmap tree. The path is used to visualize the connection state between two nodes. Red means the nodes are disconnected, green means they're connected. The next step would be to illustrate data flow (from A to B or B to A) using that path and an animation. Basically I would want to start the animation with the data transfer and stop it when the transfer is complete. Does anyone know how this could be done in WPF?
