I would like to be able to select a number of rows in my grid. Then I would like to select one of the columns in that set and change the value for all the rows simultaneously. Is that doable? Are there any samples I can follow?
We do not have any samples of such a functionality currently.
That said what I can suggest is using the SelectionChanged event in order to save the SelectedItems of the RadGridView. Then you can use the CellEditEnded event in order to update the values of all selected rows. You can encapsulate this logic in an attached behavior. I am attaching a sample project demonstrating this approach for your reference. Feel free to adapt it to your particular scenario.
I remain at your disposal for any further questions you might have.
