The collection of SelectedCells seems to get stuck after using Select All on the grid. I've seen this behavior in my app and also on your demo site (http://demos.telerik.com/silverlight/#GridView/Selection).
Steps to reproduce on demo site:
Steps to reproduce on demo site:
- Set Selection Unit to FullRow, set Selection Mode to Extended
- Select a row in the grid
- Press Ctrl-A to select all
- Select the row above the currently selected row (this should deselect everything but this row)
- Press Ctrl-C to copy the selected row
- Paste into excel, etc - the selected row is copied/pasted, along with every row above it in the grid
Anyone else seen this? Is there a workaround?
