WPF中的多个绑定

Question

Is it possible to have multiple item source bindings in xaml on a wpf control.

Currently I am using mvvm pattern and have an item binding that is bound to one object type.

ItemSource="{Binding ProcessModel}"

this then has a ItemTemplate

ItemTemplate="{DynamicResource PMDataTemplete}"

This currently is fine as I was only using one type of object. I want to extend this so I can have one or a 2nd different type of object, but it does not need to be able to bind to both at the same time.

What I am trying to achieve is the situation where one object type can be bound depending on what the user selects and the binding will work and again if the user takes a different route the other type of object is displayed on the same control.

So it is almost the idea of having a case statement based on object types for the itemsource.

Answer 1

编写自己的ItemTemplateSelector （更灵活，但更复杂）或定义需要在ItemsControl中呈现的类型的数据模板。

Answer 2

There is two options:

1. You can define datatemplates for different types.
2. You can write DataTemplateSelector as Dennis mentioned.
