Thanks for the response Ivan. I've been trying to make this work and i can't get it fully working. The code you gave me pined the row to the bottom like i wanted and works good. I can't get rid of the cell borders in my summary row though.
I played with my code and yours and here's what i found
if i comment out all the custom code you added to yours (3 lines):
this.radGridView1.MasterTemplate.ViewDefinition = new MyTableViewDefinition();
this.radGridView1.ViewRowFormatting += new RowFormattingEventHandler(radGridView1_ViewRowFormatting);
this.radGridView1.ViewCellFormatting += new CellFormattingEventHandler(radGridView1_ViewCellFormatting);
and run your project, your summary row doesn't have cell lines anyway. Mine does. what is adding them to mine but not yours?
see the attached image for an example.
