I have a master/detail RadGrid that is using the detail row footer to display a sum of the detail rows. What I need to do is to display only the detail row footer row values but hide all of the actual detail rows. How can I do this?

Thanks,

Steve Holdorf

Hello Steve,

Could you please try the following approach and let me know if it helps you?
protected void RadGrid1_PreRender(object sender, EventArgs e)
{
    HideDetailItems(RadGrid1.MasterTableView);
}
public void HideDetailItems(GridTableView tableView)
{
    GridItem[] nestedViewItems = tableView.GetItems(GridItemType.NestedView);
    foreach (GridNestedViewItem nestedViewItem in nestedViewItems)
    {
        foreach (GridTableView nestedView in nestedViewItem.NestedTableViews)
        {
            foreach (GridDataItem dataItem in nestedView.Items)
            {
                dataItem.Visible = false;
            }
            if (nestedView.HasDetailTables)
            {
                HideDetailItems(nestedView);
            }
        }
    }
}

That should do the trick.

Kind regards,
