Unfortunately the RadGrid does not support build in the desired functionality. However with the following code snippet you could show the footer aggregates into the RadGrid header:
sender, EventArgs e)
GridHeaderItem header = RadGrid1.MasterTableView.GetItems(GridItemType.Header)
GridFooterItem footer = RadGrid1.MasterTableView.GetItems(GridItemType.Footer)
var value = footer[column.UniqueName].Text;
Additionally I am sending you a simple example which demonstrates the desired functionality. Please check it out and let me know if it helps you.
Looking forward for your reply.
