Execute DataTemplateSelector on Each Click

Question

Hi,

I am using DataTemplateSelector in TreeViewControl and as it has a virtual method called "SelectTemplate".

SQL

public override DataTemplate SelectTemplate(object item, DependencyObject dependencyObject)
 {

}

As we all know that, SelectTemplate method will be called when we click on the tree view node. Now, again if we click on same node it does not execute SelectTemplate method as we all know.

But is there any option, property or any alternatives so that SelectTemplate method gets called everytime I click on any node or same node so that it calls SelectTemplate method.

Thanks in advance :)

As we all know? SelectTemplate is called when a DataTemplate is needed. SelectTemplate has nothing to do with a click event, unless that click event is expanding a tree node and the system needs to select templates for the newly visible node(s). If you want to change templates when an event occurs then you'll need to implement that yourself.

Why do you need to do it from code? There is an alternative which I describe here[^]. By doing this, you have one DataTemplate (which controls the conditions for switching the templates), and you change the other DataTemplates to ControlTemplates.

No problem. As long as there's some form of trigger to bind to, this method works. It works so well that I no longer use manual DataTemplateSelectors.
