Hello,

As a work-around one can use the current RadControls wrappers API to write a helper method iterating through each gridview row and expanding it.

From the API:
RadGridView.Rows – give the list of all rows in the grid
GridViewRow.Expand() – expand the row, basically finding and clicking on a toggle button
Or
GridViewRow.IsExpanded – just changes the IsExpanded value of the actual GridViewRow in the application.

The RadGridView control wrappers reside in the Telerik.WebAii.Controls.Xaml namespace for Silverlight and the Telerik.WebAii.Controls.Xaml.Wpf namespace for WPF.

I hope this helps!
