Thank you for writing.
If I understand correctly, you want to show the popup of a cell in GridViewComboBoxColumn
. If so, you need to first call the BeginEdit
method of the desired cell, and then handle the CellEditorInitialized
event, where you can open the popup:
sender, GridViewCellEventArgs e)
RadDropDownListEditor editor = e.ActiveEditor
sender, EventArgs e)
More information about the editors in the grid is available here: http://www.telerik.com/help/winforms/gridview-editors.html
I hope this helps.
All the best,
the Telerik team
