I have a RadGanttView in which you can change the task in the columns. So if I click into the cells I can edit the value in it. After the Editing I do a validation. If this validation fails, a errormessage is shown. If this message is showing, I have to set the wrong cell in edit mode. But I wasn't able to do that.
How can I set a specific cell to edit-mode by code?
I already tried so call the TaskEdititngEvent, but didn't work as excpected:
var editingEventArgs = new TaskEditingEventArgs(RadGanttView.TaskEditingEvent, neuerTask);
GanttDiagramm.RaiseEvent(editingEventArgs);
