    I have a series of Radgrids (linked to Objectdatasources), and I'm wondering if there is a way to detect and *not show* a radgrid if that data source has no rows.

    There are 5 different Radgrids, and typically for any specific parent item no more than 2 or 3 will have any content, but it always changes. hence I'd like to show the grid if there is any data, hide it otherwise.

    Any and all suggestions are appreciated.

    Hi Derek,

    You can check whether a particular RadGrid has data items in the control's PreRender event handler and set Visible = false:

    protected void RadGrid1_PreRender(object sender, EventArgs e)
    {
        RadGrid grid = sender as RadGrid;
        if (grid.MasterTableView.Items.Count == 0)
        {
            grid.Visible = false;
        }
    }


    Best wishes,
