I'm using the RadGrid from prometheus Q3 2007. What I want to do is to add a row in the header of the grid to group the colomuns. Exemple:
... Followed by the standart header, assuming that my grid has 4 columns...
I'm creating my grid programmatically and adding it to a placeholder like the exemple showed here
in the section "Creating ItemTemplate/EditItemTemplate of GridTemplateColumn programmatically".
I' using visual studio 2008, framework 3.5.
