specifying ItemTemplate for RadGridView

[Matt Meleski]

Hi ,

My end goal is to do something similar to a ItemSource Control and dynamically switch out the the Column defintions
for a Grid. In the below Xaml, there are two DataTemplates. I would like to be able to switch out the between MyTemplateOne and 
MyTemplateTwo, by setting the   ItemTemplate property on the RadGridView. Of course this does not work. Is there some other way  way to do this?
Something, that does work is a the RowDetailsTemplate property :
RowDetailsTemplate="{StaticResource EmployeeInfoRowDetailsTemplate}"
But I would like to do the same on the regular Rows.

Thanks, Matt

Hi Matt Meleski,


Unfortunately this is difficult to do in xaml. The approach here would be - have a two collections of columns either declared in code behind or as static resources.
Then when you need to switch the columns use the RadGridView.Columns.Clear() and then RadGridView.Columns.AddRange( .... ) passing here one of your collections.

Looking at your sample code I note the set of columns is almost the same for the two cases and differs by only the last two columns. So you can also add/remove only those two columns in code behind or if they are always present - just toggle their visibility and hide them when not needed.
