Hi Stefan,
thanks for your help, I make a little bit modification, when release the button at selected row and the control key was pressed, the row is deselected. I use OnMouseUpLeft and a private flag at behavior Class.
I have other doubt, I only Drag if the .AllowRowReorder=True at source RadGrid, but I don´t like reorder the source, How I supress ou disable the reorder event
Thanks
Paulo
