问题 I have a DataGrid with 2 columns. Based on the first column which is bound to ParameterDataType I want to load the appropriate template in the second column. Problem with this code is before the DataGrid has been loaded, the template selector is executing as a result the item is null.

问题 I try to make a customized ListView which fills each list item with some stuff and an initial Checkbox if desired. Currently no Checkbox is displayed so I guess my code of the ContentControl stuff is somehow erroneous. <ListView xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"> <ListView.View> <GridView> <GridViewColumn> <GridViewColumn.CellTemplate> <DataTemplate> <!-- Each list item: [Checkbox] Label --> <StackPanel

问题 So to keep the question simple what I need for example is to use something like this dozens of times; <Rectangle> <i:Interaction.Triggers> <i:EventTrigger EventName="MouseLeftButtonDown"> <ei:ChangePropertyAction TargetName="AnotherObjectOnTheView" PropertyName="Visibility" Value="Visible" /> </i:EventTrigger> </i:Interaction.Triggers> </Rectangle> Except obviously I don't want to paste that dozens of times everywhere I need it.

问题 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

问题 I liked this answer, and it almost fit me. But, how can I achieve this if my DataTemplate is in a external ResourceDictionary ? I'm using Prism and I provide the DataTemplates (for generic CRUD views) by each module, by using files like this: <ResourceDictionary ... some hidden ns here ... > <DataTemplate DataType="{x:Type model:Operation}"> <vw:OperationView /> </DataTemplate> <DataTemplate DataType="{x:Type model:Customer}"> <vw:CustomerView /> </DataTemplate> </ResourceDictionary> Then I

问题 Why does this not resolve the datatemplate? <Window.Resources> <DataTemplate DataType="system:DateTime" > <Grid Background="Aqua"> <TextBlock Text="{Binding Day}"></TextBlock> </Grid> </DataTemplate> </Window.Resources> <Grid> <ContentControl Content="{x:Static system:DateTime.Now}"/> </Grid> Writing a TemplateSelector feels like an overkill. 回答1: DataType design suggests the presence of a directive x:Type like that: <DataTemplate DataType="{x:Type system:DateTime}"> <Grid Background="Aqua">
