Hi,

I have implemented the same and get the error in "EmptyDataTemplateBehavior" class, when compile the project and the error is:

 Cannot apply indexing with [] to an expression of type 'System.Collections.Generic.IEnumerable<System.Windows.Controls.Grid>'   in EmptyDataTemplateBehavior.cs

Please give a solution for the same.

Thanks

Hi Kevin,

Please use FirstOrDefault() method in this case instead of index.

Hi Sandy,

Could you try the approach mentioned above calling FirstOrDefault() method instead of using an index ? Did you get the same exception ?

Hi Kevin,

You can get the root grid as:

//Option 1:
Grid rootGrid = _grid.ChildrenOfType<Grid>().FirstOrDefault();
//Option 2: 


Grid rootGrid = _grid.ChildrenOfType<Grid>().ElementAt(0);

Hello Kevin,

I am sending you a sample project illustrating how you can define empty data template for different grids in separate tab items.
I hope that helps.
