I've been searching around trying to figure out how to apply an empty data text value when my grid has no rows to display. I see it's not something that's built into the RadGridView (not sure why) and it has to be manually created. I've tried a few of the example projects I found but none seem to work correctly. The one I found that actually compiles will show the empty data text even if the data grid has rows. The empty data text is underneath the grid rows.

Thoughts on how to go about doing this?

Thanks!

Hi Maya,
Thank you for the prompt reply. The blog you supplied as a reference is the one I'm currently looking into now, however, there appears to be a bug as I get the following error for this line of code:

Grid rootGrid = gridView.ChildrenOfType<Grid>()[1];

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

I can't seem to figure out why this would throw this error if others have been successful using it. Can you help with this error?

Thanks!
Adam

Hi,

 You can use:

Grid rootGrid = gridView.ChildrenOfType<Grid>().ElementAt(1);  

All the best,

Hi Vlad,
Thanks for that tip, however I'm getting this error now..Sorry to be such a pain...What am I missing now?

'System.Collections.Generic.IEnumerable<System.Windows.Controls.Grid>' does not contain a definition for 'ElementAt' and no extension method 'ElementAt' accepting a first argument of type 'System.Collections.Generic.IEnumerable<System.Windows.Controls.Grid>'


Thanks so much!!

Hello,

 Most probably you do not have:

using System.Linq;
