I'm not sure if this is the better forum, but I'll start here unless directed to the GridView threads.  When a user initiates a drag and drop from a DataGrid, is it possible to freeze the grid at the current location so no scrolling takes place until the mouseup (i.e. drop).

Thanks.

Hi Mark,


The scrolling behavior when performing drag and drop is enabled by default. Still you may disable it by setting the AutoBringIntoView property of the RadDragAndDropManager. A possible approach may be to set it to false on the DragQuery and enable it in the DropQuery:

private void OnGridViewDragQuery(object sender, DragDropQueryEventArgs e)
{
    var draggedItem = e.Options.Source;
    if (e.Options.Status == DragStatus.DragQuery)
    {      
                ....
      RadDragAndDropManager.AutoBringIntoView = false;      
    }
}

Please let me know whether this approach corresponds to your requirements.

 

All the best,
