Freeze header rows

Hi, In my application i have 2 header rows and i want to freeze them. when i used following code m_PretestListingGrid.Model.Rows.FreezeRange(0,2); m_PretestListingGrid.Model.Rows.FreezeSelection(); it freezed the first 2 data rows. Can you tell how do we freeze the header rows?

Row 0 is the default header and row 1 would be your second header row. So try this code: //2 header rows m_PretestListingGrid.Model.Rows.HeaderCount = 1; // freeze the top 2 rows (includes headers) m_PretestListingGrid.Model.Rows.FrozenCount = 1;
