I have an application with two RadGrids on the page together. I have drag/drop functionality for each grid, which works fine. However when dragging from one grid to the other, It creates the Javascript errors copied below. On some environments, depending on the version/settings of the browser, it can cause a 404 error. I have tried to solve this issue by adding code to my RowDrop event handler that ignores all drops from other grids. But these errors are happening before the RowDrop is called.
How can I prevent these errors without losing the ability to drag/drop within the same grid?
Message: Sys.WebForms.PageRequestManagerServerErrorException: Cannot find a cell bound to column name 'Tasks'

Hi Paul,
The RowDrop client event cannot be cancelled, but the RowDropping event can. You can check in the RowDropping handler what is the destination of the dropped rows and cancel the event if it is another RadGrid.

Here is an example which performs a similar check:
