Hi,
We are trying to verify the contents of a RadGridView, but are not getting the correct number of rows or cells. The code we are using is as follows :

​SilverlightApp app = ActiveBrowser.SilverlightApps()[0];
​Telerik.WebAii.Controls.Xaml.RadGridView rgv = app.Find.ByType<Telerik.WebAii.Controls.Xaml.RadGridView>();

Log.WriteLine(rgv.Rows.Count.ToString());
Log.WriteLine(rgv.Rows[0].Cells.Count().ToString());

Now we could have 500 rows and 5 columns, but the Log just shows the row count to be 2 and cell count to be 1. Any ideas as to why it is not bringing back the full RadGridView ??
As a heads up the RadGridView is being populated by Dynamc Data (as seen in this demo ... http://demos.telerik.com/silverlight/#GridView/DataSources )

Cheers ... Rob.

Hello,

That can indeed happen in case of virtualized items control in Silverlight, which is usually the case with RadGridView. Virtualization has been introduced in Silverlight for performance reasons, however it makes the automation quite hard. The problem is items (rows/columns in this case) are not available in the visual tree until you scroll to make them visible (in addition you can't rely on the other of items as you can get them from the visual tree).

Please check this article for example how to accomplish iterating over all items in virtualized GridView. There are a few similar articles in the same section which you may find useful as well.
