Wpf – Different item template for each item in a WPF List

itemtemplatewpf

I have many items inside a list control. I want each item to have a different item template depending on the type of the item. So the first item in the list is a ObjectA type and so I want it to be rendered with ItemTemplateA. Second item is a ObjectB type and so I want it to have ItemTemplateB for rendering. At the moment I can only use the ItemTemplate setting to define one template for them all. Any way to achieve this?

the ItemTemplateSelector will work but I think it is easier to create multiple DataTemplates in your resource section and then just giving each one a DataType. This will automatically then use this DataTemplate if the items generator detects the matching data type?

<DataTemplate DataType={x:Type local:ObjectA}>
   ...
</DataTemplate>

Also make sure that you have no x:Key set for the DataTemplate.

Wpf – ListBox vs. ListView – how to choose for data binding

A ListView is a specialized ListBox (that is, it inherits from ListBox). It allows you to specify different views rather than a straight list. You can either roll your own view, or use GridView (think explorer-like "details view"). It's basically the multi-column listbox, the cousin of windows form's listview.

If you don't need the additional capabilities of ListView, you can certainly use ListBox if you're simply showing a list of items (Even if the template is complex).

You can use DataTriggers. Use code like this (switching templates depending on if value of SomeItemProperty is 0 or not):

<DataTemplate x:Key="MyItemTemplate">
    <StackPanel>
        <StackPanel Name="normalStackPanel">
            <!-- template for normal row -->
        </StackPanel>
        <StackPanel Name="emptyStackPanel" Visibility="Collapsed">
            <!-- template for empty row -->
        </StackPanel>
    </StackPanel>

    <DataTemplate.Triggers>
        <DataTrigger Binding="{Binding SomeItemProperty}" Value="0">
            <Setter TargetName="normalStackPanel" Property="Visibility" Value="Collapsed" />
            <Setter TargetName="emptyStackPanel" Property="Visibility" Value="Visible" />
        </DataTrigger>
    </DataTemplate.Triggers>
</DataTemplate>

Hope it helps.
