Hi,
We are using WinForms Q1 2008 SP1 RadGridView.
The problem we are facing is that even though we have disabled drag drop of the columns in the grid, if the user tries to drag any column header outside the form or within the grid other column and wait for few seconds (>= 5 Sec) , following runtime error is coming
object reference not set to instance of an object.
What we are trying to do is disable column drag and drop of grid columns, I have already tried MasterGridViewTemplate.AllowDragToGroup = False , column chooser , column reorder everything false.
Note : we are having timer tick event set for 5 seconds which refreshes the grid every after 5 sec.
if we remove timer event , above problem gets resolved.
Even we dont want effect of drag and drop.
We need solution for this with timer enabled ASAP.
Please help.
Regards
Vishal
