datatrigger

I have a listview that you select a row/item on. This is linked to a datatrigger that displays an image on the row. The image should only be displayed when the row is selected. This part works fine, however when you move the focus to something else, such as a textbox, or a messagebox is displayed, the listviewitem loses focus ie the highlight on the row is no longer displayed. The problem is that my image still remains. It should be hidden/collapsed when the listview loses focus... It works fine if you select a different item/row on the listview. Can anyone help on this please? <Style x:Key=

I am trying to switch the content of a contentpresenter based on a datatrigger.I want to display a usercontrol in the contentpresenter.content, if i have a value set or else i need to display an error message.But the binding on my datatrigger fails stating that the property is not found.I cant get the datacontext to inherit for the datatrigger checking.I can make it work by using the commented out code.But i am confused why it doesn't work the normal way. <ContentPresenter.Style> <Style TargetType="{x:Type ContentPresenter}"> <Setter Property="Content" Value="{Binding UC}"/> <Style.Triggers> <

Is it possible to use a wild card or call a method to work out if a DataTrigger should be applied? I currently have my DataList bound to an IEnumerable that contains file names and I want the file names to be greyed out if there files extension starts with "old" My non-working dream xaml markup looks something like this: <DataTemplate.Triggers> <DataTrigger Binding="{Binding}" Value="*.old*"> <Setter TargetName="FileName" Property="Foreground" Value="Gray"/> </DataTrigger> </DataTemplate.Triggers> The only workable solution I've been able to come up with is to insert a new view model property

I have a grid whose rows need to be resized dynamically based on the view model. I'd like to do something like the following: <RowDefinition Height="2*"> <RowDefinition.Style> <Style> <Style.Triggers> <DataTrigger Binding="{Binding Path=ShowSection}" Value="True"> <Setter Property="RowDefinition.Height" Value="2*"/> </DataTrigger> <DataTrigger Binding="{Binding Path=ShowSection}" Value="False"> <Setter Property="RowDefinition.Height" Value="0"/> </DataTrigger> </Style.Triggers> </Style> </RowDefinition.Style> </RowDefinition> This compiles, throws no errors, but doesn't seem to have any effect

I have the following DataGrid cell, which I would like to animate its background colour briefly as soon as the underlying LastTradePrice property changes its value. <DataGridTextColumn Header="Last Trade Price" Binding="{Binding LastTradePrice}"> <DataGridTextColumn.CellStyle> <Style TargetType="DataGridCell"> <Style.Triggers> // ??? <DataTrigger Binding="{Binding LastTradePrice}" Value="True"> <DataTrigger.EnterActions> <BeginStoryboard> <Storyboard> <ColorAnimation To="Aqua" Duration="0:0:0.3" Storyboard.TargetProperty="Background.(SolidColorBrush.Color)"/> </Storyboard> </BeginStoryboard> <

I'm beginner in WPF. I want to set Visibility to Hidden on a Radiobutton when the databind value is equal to Null. I'm using WPF Toolkit. This is my code but it doesn't work : <dg:DataGrid x:Name="dtGrdData" HorizontalScrollBarVisibility="Hidden" SelectionMode="Extended" CanUserAddRows="False" CanUserDeleteRows="False" CanUserResizeRows="False" CanUserSortColumns="False" AutoGenerateColumns="False" RowHeaderWidth="0" RowHeight="50" > <DataTrigger Binding="{Binding P_DAY_PRICE}" Value="{x:Null}"> <Setter Property="RadioButton.Visibility" Value="Hidden"></Setter> </DataTrigger> <dg:DataGrid

I want the ContentTemplate to vary according to the value in the DataTrigger . And yes, I considered using a DataTemplateSelector , but now I need a DataTrigger or better said a MultiDataTrigger . Please take a look at the following sample app, the DataTemplate doesn't change: <Window x:Class="Window1" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:src="clr-namespace:WpfApplication1"> <StackPanel> <CheckBox IsChecked="{Binding BoolProperty, RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type src
