Different item template for each item in a WPF List?

Question

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?

Answer 1

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.

I forgot to put in the {x:Type... stuff, please try again! – Bombastic

Also make sure that you have no x:Key set! – Bombastic

it seems the link is dead.. Do you have any similar source to refer to? – Automata

The quotes around {x:Type local:Object} are missing. And here is a link to a similar solution with ItemsControl and DataType binding in WPF. – Dollfuss

Answer 2

Have a look at the ItemTemplateSelector property of your list control. You can point it to a custom TemplateSelector and decide which template to use in code.

Here's a blog post describing TemplateSelectors:
