Hi, I am using an AdvancedDataGrid where I allow the user to drag and drop datagrid columns to an area(top-section) above the datagrid. This works fine but when a user drops a column in top-section the columns reordering in the datagrid also takes place. That is if the user drags the fifth column to top section in such a way that the fifth column falls directly above the second column, the fifth column becomes the second column. I want to have a logic where if a user drags a column to the top section the column reordering should be disabled. If he drags the column to any other column inside the datagrid, reordering should work.
For this I tried to stop the event propagation for the MouseEvent.MOUSE_UP for both the datagrid and datagridheaderrenderer. But this did not work. I observed that if I stop the propagation of MouseEvent.MOUSE_DOWN the reordering stops working. But I cannot use MouseEvent.MOUSE_DOWN as I do not know where the column has been dragged to in this event. Also in the AdvancedDataGridBaseEx class it looks like the code for reordering is inside the mouseUpHandler but I am not able to stop it execution. I have tried other events like DragEvents and DataGridEvent.HEADER_RELEASE but none seems to work. Please let me know on how I could achieve this. TIA GAurav
