I've attempted to use the FrozenGridView class. I've successfully registered the control in a VS2005 test website and I"m able to add the control to a webpage but when I try to add a column I receive an error message:
Error invoking 'Edit Columns....' Details: The method or operation is not implemented.
As a workaround, I can take a standard Gridview control, and create the required columns. If I cut and paste the "rwg:FrozenGridView" tag prefix on to the standard gridview control, it doesn't have the above problem unless I then try to add an additional column.
I can compile the page and it will render the grid, columns, data and freeze the column header as intended.
Anyone have any suggestions?
