I want to Design something like this
Suppose
there 3 row with some header and under each row mutiple rows are there
Rate 3.5
Text Image Text
Score 2.4
Text Image Text
Quanity 1.5
Text Image Text
You can set up grouping expression for rows and customize header-row-of-grouped-childrow to show custom-text like "Rate 3.5" or "Score 2.4" or "Quanity 1.5".
To customize header-row-of-grouped-childrow, override onitemcreated event of RadGrid and check if e.Item.ItemType == Telerik.Web.UI.GridItemType.GroupHeader to add custom-text
