如何将 wpf ListBox 的 ItemTemplate 嵌入到 Window 的资源中？

Question

Sorry if this is a basic question, but how can I take an ItemTemplate that I have for a ListBox, and put it in the resources for the window so that more than one ListBox can use it.

Here's some XAML:

<Window x:Class="Example">
    <Window.Resources>
        <DataTemplate x:Key="dtExample">
            <ListBox.ItemTemplate>
            // styles go here...
            </ListBox.ItemTemplate>
        </DataTemplate>
    </Window.Resources>
    <ListBox ItemTemplate="{StaticResource dtExample}">
    // items go here...
    </ListBox>
</Window>

This is throwing a "Attached property has no setter" design-time error. I've removed portions of code that I didn't think would matter, for sake of brevity.

Thanks

Answer 1

just add your itemtemplate to your window's resource and add a key:

<Window.Resource>
 <DataTemplate x:Key="myTemplate">
  ....
 </DataTemplate>
</Window.Resources>

and then apply it with something like this:

<ListBox ItemTemplate="{StaticResource myTemplate}">
 ...
</ListBox>

Answer 2

you provided the following code:

 <DataTemplate x:Key="dtExample">
        <ListBox.ItemTemplate>
        // styles go here...
        </ListBox.ItemTemplate>
    </DataTemplate>

but this will not work. you cannot provide <ListBox.ItemTemplate> directly within your template. you don't need this here. just create a simple datatemplate and it should work.

I know that the post is too old to be interesting for the author, yet i may be interesting for those who have the same problem and google it. As I may see the problem is you should use ListBox.ItemTemplate inside ListBox. For instance, <ListBox ...><ListBox.ItemTemplate> ... </ListBox.ItemTemplate></ListBox>

Answer 4

the subject is old but here is the solution:

<Window.Resources>
    <Style x:Key="ListBoxItem_Color" TargetType="{x:Type ListBoxItem}">
        <Setter Property="Template">
            *//style*
        </Setter>
    </Style>
</Window.resources>

<ListBox x:Name="MyListBox"
         ...
         ItemContainerStyle="{StaticResource ListBoxItem_Color}">
      <.../>
</ListBox>

Answer 5

I think the problem is that you should x:Key properties in your resources instead of the x:Name..

Change that, and it will work like a charm :)

Do you have the following tags in your Window class?
