I have implemented a drag-drop from one Radgrid to another. When the target grid receives a drop, it updates a SQL table. The target grid is using a DataSourceID to the said SQL table. I have placed a Radgrid.Rebind() in the postback call. Everything works great - except for the first time. When I drop the first item, the target grid does not update but I can see that it updated the SQL table. After the first item, I can continuously drop more items from the source grid and the target grid will refresh every time to represent the data in the SQL table using the Rebind in postback. What would cause the first instance of a rebind to not work properly?
I saw on some posts to place the Rebind in the page's PreRender event but that also did not work. Any suggestions are much appreciated. Thank you.
