Hi,
I am trying to use the show group panel, allowing a user to drag the column names into it, however it keeps throwing an error:
"Error: Sys.WebForms.PageRequestManagerServerErrorException: Invalid group by expression: 'Group By' clause missing"
However if I define an item in the configuration manager it works, properly, So why can't I drag and Drop? :(
I can't see any errors myself and it all works fine on the page except this group panel,
Many thanks for your help
Ryan
