  • Bind event in custom WPF control to command in ViewModel

    - by Jon Archway
    Hi, I have a custom control that has an event. I have a window using that custom control. The window is bound to a viewmodel. I would like to have the event from the custom control direct to an ICommand on my viewmodel. I am obviously being dense here as I can't figure out how to do this. Any assistance is most welcome. Thanks

  • Have a clickable button on top of a combobox in WPF

    - by Travyguy9
    I can get a button to appear and be clickable in the drop down list of a combo box, but I cannot get the selected combo box item (the drop list is closed) to have the button be clickable. It always skips the button click and just opens the drop down list. I basically want the Button_Click event handler that I setup to be called once it is clicked. Here is my sample combo box that shows the button but is not clickable once it is in the selected item: <ComboBox x:Name="MyCombo" Width="200" Height="30" ItemsSource="{Binding ListCombo}"> <ComboBox.Resources> <DataTemplate DataType="{x:Type local:ComboItemClass}"> <StackPanel Orientation="Horizontal"> <TextBlock Text="{Binding Path=SampleText}" Width="120" /> <Button Width="20" Content="..." Click="Button_Click"/> </StackPanel> </DataTemplate> </ComboBox.Resources> </ComboBox>

  • Applied style in WPF ignores properties.

    - by Quenton Jones
    Here's the conundrum. In two different places in my application, I use a border with the exact same appearance. In an never-ending fight against code bloat and unmanageable code, I want to define the border's appearance in a style to use when I create the border. Strangely, several of the properties I set are being ignored. Here's the code I use to create the style. Simple enough. Style borderStyle = new Style(typeof(Border)); borderStyle.Setters.Add(new Setter(Border.BorderBrushProperty, Brushes.Black)); borderStyle.Setters.Add(new Setter(Border.BorderThicknessProperty, new Thickness(4))); borderStyle.Setters.Add(new Setter(Border.OpacityProperty, 1.0)); return borderStyle; But when I set the style, the opacity property is left at its original value of 0.7. I have also tried setting the background of the border to a brush I created. It too is ignored. Thanks for any insights you may have.

  • WPF Binding Path=/ not working?

    - by Mark
    I've set up my DataContext like this: <Window.DataContext> <c:DownloadManager /> </Window.DataContext> Where DownloadManager is Enumerable<DownloadItem>. Then I set my DataGrid like this: <DataGrid Name="dataGrid1" ItemsSource="{Binding Path=/}" ... So that it should list all the DownloadItems, right? So I should be able to set my columns like: <DataGridTextColumn Binding="{Binding Path=Uri, Mode=OneWay}" Where Uri is a property of the DownloadItem. But it doesn't seem to like this. In the visual property editor, it doesn't recognize Uri is a valid property, so I'm guessing I'm doing something wrong. It was working before, when I had the data grid binding to Values, but then I took that enumerable out of the DownloadManager and made itself enumerable. How do I fix this? PS: By "doesn't work" I mean it doesn't list any items. I've added some to the constructor of the DM, so it shouldn't be empty.

  • Setting Icon for wpf application (VS 08)

    - by baron
    Hi everyone, Before going much further i'll mention I have tried solutions in following: http://stackoverflow.com/questions/320677/how-do-i-set-the-icon-for-my-application-in-visual-studio-2008 http://stackoverflow.com/questions/198848/set-application-icon-from-resources-in-vs-05 I am trying to set an icon for my application. AFAIK, I need potentially 3 images? 1 image is the actual image in explorer when clicking on the .exe (thumbnail for the exe) 1 image (tiny) in the top left corner (16 x 16? Not entirely sure) 1 image in the start menu dock, to the left of the app (maybe 32x32? again not sure) So thats fine. Now I have selected an Icon. How do I use it in one of above situations? I have tried adding it in resources, nothing seems to happen. Following that first SO solution, "First go to Resource View (from menu: View -- Other Window -- Resource View). Then in Resource View navigate through resources, if any. If there is already a resource of Icon type, added by Visual Studio, then open and edit it. Otherwise right-click and select Add Resource, and then add a new icon." The resource view is empty, and I cannot right click in this view. If I right click on the solution properties resources I can add the icon image, but it doesn't show in either of the locations listed above. (or anywhere that I can see) What am I doing wrong?

  • WPF Converter to look up in generic list

    - by user310046
    I have a list of data where I keep e.g. countries with code, name and some other data. List<Country> countries = <deserialized objects from file> which consist of objects like this: public class Country { public string Code { get; set;} public string Name { get; set;} } The object which use as a DataContext may look like this: public class Address { public string StreetName{ get; set;} public string CountryCode { get; set;} } Then in my XAML I want to do something like this to show the name of the country <TextBlock Text="{Binding Path=CountryCode, Converter={StaticResource CountryNameLookupConverter}}"/> But how can I make the CountryNameLookupConverter use the countries list I read from the xml file?

  • WPF: Can't get to original source from ExecutedRoutedEventArgs

    - by Ikhail
    I have a problem getting to the original source of a command using ExecutedRoutedEventArgs. I'm creating a simple splitbutton, in which a menu will appear below a dedicated button, as another button is pressed. When I click a menuitem in the appearing menu a command is fired. This command is registered on the splitbutton. And the idea is to get to the menuitem beeing clicked, by using the ExecutedRoutedEventsArgs. Ok, now the problem. If I choose to have the popup menu shown by default (IsOpen="True") and I click one of the menuitems I can get to the originalsource (thus the menuitem) from the ExecutedRoutedEventArgs - no problem. However, if I first click the button to show the menu and THEN click on a menuitem, the originalsource of the command will be the button instead of the MenuItem! Here's the controltemplate for the splitbutton: <ControlTemplate TargetType="{x:Type usc:SplitButton}"> <StackPanel Orientation="Horizontal"> <Button Name="mybutton"> <StackPanel> <Popup usc:SplitButton.IsPopup="True" IsOpen="True" Name="myPopup" PlacementTarget="{Binding ElementName=mybutton}" StaysOpen="False" Placement="Bottom"> <Border BorderBrush="Beige" BorderThickness="1"> <Menu Width="120"> <MenuItem Header="item1" Command="usc:SplitButton.MenuItemClickCommand" /> <MenuItem Header="item2" /> <MenuItem Header="item3" /> </Menu> </Border> </Popup> <TextBlock Text="MySplitbutton" /> </StackPanel> </Button> <Button Content="OK" Command="usc:SplitButton.ShowMenuCommand" /> </StackPanel> </ControlTemplate> The OK button fires a ShowMenuCommand on the SplitButton, which sets the IsOpen property on the Popup to True. Any ideas why the OK button (after having activated the menu) is the OriginalSource when a menuitem is clicked? Thanks.

  • WPF problem modify style of images in multiple Button Templates

    - by user556415
    I'm trying to create a control panel for a video camera, the panel has buttons for up, down, left and right etc. Each camera function up, down, left and right is represented by three images (see code below) for the left side, middle and right side. The control panel is circular so the corner images kind of overlap (its complicated to explain this without a visual). When I click on up for example I have to hide the initial three images (leftside, middle and right side) and display another three images for left , middle and right that indicate that the button is pressed. I am achieving this by having a grid inside a button template. The problem I have is that for the corner images for the control there are really four images that represent this. For example for the top left corner the four images would be represent 1. Top not clicked. 2. Top Clicked and 3. Left Not clicked and 4. Left Clicked. My problem is if I need to make the images contained within the Top button have precedence when the top control is clicked or the images in the left button have precedence when the left button is clicked. So it's like I want to modify the left button's image visible property when the top button is clicked and vise versa. This is really difficult to explain so I apologize if it makes little sense but I can email the source code on request if anyone is interested in my predicament. <Grid> <Canvas> <!--<StackPanel>-->

  • WPF Databinding and Styling based on Data in an item in an IList

    - by Nate Bross
    I have a ListBox bound to a list of Items (for arguement, lets say its got a string and two dates Entered and Done). I would like to make the background color of items in the ListBox have a gray color if the Done DateTime is != DateTime.MinValue. Edit: Should I make a converter? and convert DateTime to a Brush based on the value of the DateTime? Is something like this my best option? or is there a simple Xaml snippet I could use? [ValueConversion(typeof(DateTime), typeof(Brush))] class MyConverter : IValueConverter { ... }

    I am trying to clip a 4:3 image with a circle within a grid control. I need the circle clip to reveal the image from the middle in a perfect circle. See below. The circle should dynamically re-size with the image. I have tried Canvas.Clip and Ellipse+VisualBrush without achieving the correct behavior. Thanks!

  • WPF Button on or off coloured state

    - by wonea
    I'm trying to create a set of button which have an off or on state, much a checkbox without the check. Ideally I want the colour to change to represent the two different states off(red), green(on). I've tried setting a control template but this only changes the colour for a selection, then reverts back to it's original colour once the mouse leaves the button's vicinity. <ControlTemplate.Triggers> <Trigger Property="IsPressed" Value="True"> <Setter Property="Background" TargetName="Background" Value="Green"/> </Trigger> </ControlTemplate.Triggers>

  • WPF Logical Tree - bottom up vs. top down

    - by Dor Rotman
    Hello, I've read the MSDN article about the layouts pass, that states: When a node is added or removed from the logical tree, property invalidations are raised on the node's parent and all its children. As a result, a top-down construction pattern should always be followed to avoid the cost of unnecessary invalidations on nodes that have already been validated. Now lets assume I do this. Won't the users see the control tree populate itself and the layout change several times during the control creation process? I want the whole control tree to just appear completely full. Thanks!

  • ReorderListView in WPF

    - by Philipp Schmid
    I love the controls from the Bag-Of-Tricks. I am interested in modifying the ReorderListBox control to get a ReorderListView control. However, simply changing the base class from ListBox to ListView is not working. When I try to add a ReorderListView to XAML like this: <lib:ReorderListView Grid.Row="1"> <ReorderListView.View> <GridView> <GridViewColumn Header="Data1" /> </GridView> </ReorderListView.View> </lib:ReorderListView> I get an error ("The tag 'ReorderListView.View' does not exist in XML namespace 'http://schemas.microsoft.com/winfx/2006/xaml/presentation'.) How do I modify the ReorderListBox example to get this to work? Has anyone already succeeded in doing this?

  • Updating the foreground of a label on window active property-WPF

    I have a label which shows the name of the window. I want to update the colour of the label on the IsActive property of the window using styles and triggers so that all the labels inheriting this style should exhibit the same property. Please can anyone suggest me how? I tried like this: <Style TargetType="{x:Type Label}" x:Key="HeaderLabel"> <Style.Triggers> <DataTrigger Binding="{Binding (Window.IsActive)}" Value="True"> <Setter Property="FontSize" Value="15"/> <Setter Property="FontWeight" Value="Bold"/> <Setter Property="FontFamily" Value="Arial"/> <Setter Property="Foreground" Value="Black"/> <Setter Property="HorizontalAlignment" Value="Left"/> </DataTrigger> <DataTrigger Binding="{Binding (Window.IsActive)}" Value="False"> <Setter Property="FontSize" Value="15"/> <Setter Property="FontWeight" Value="Bold"/> <Setter Property="FontFamily" Value="Arial"/> <Setter Property="Foreground" Value="White"/> <Setter Property="HorizontalAlignment" Value="Left"/> </DataTrigger> </Style.Triggers> </Style>
