Public Property CellEditingTemplateSelector As DataTemplateSelector

Dim instance As UXGridView
Dim value As DataTemplateSelector
 
instance.CellEditingTemplateSelector = value
 
value = instance.CellEditingTemplateSelector

public DataTemplateSelector CellEditingTemplateSelector {get; set;}

public:
property DataTemplateSelector^ CellEditingTemplateSelector {
   DataTemplateSelector^ get();
   void set (    DataTemplateSelector^ value);
}

A rather unique scenario is where the users would like to have different editing control for the same column that depends on the data that currently being edited. This can be achieved elegantly in UXGridView by using CellEditingTemplateSelector. It works similarly to any other template selectors.

The following code shows how to create the editing template selector and used it in UXGridView.
