Before binding your DataTable(DataSource) to the grid, check the row count of the DataTable. If its empty (row count = 0) then add a dummy row to the DataTable and then bind it with the grid. Also make the visibility of the dummy row in the grid to false.

Here is some sample code

        if(dt.Rows.Count > 0 )
        {
            //DataSource is not empty
            gvResults.DataSource = dt;
            gvResults.DataBind();
        }
        else
        {
            //DataSource empty, add dummy row
            dt.Rows.Add(dt.NewRow());
            gvResults.DataSource = dt;
            gvResults.DataBind();
           //Make dummy row invisible
            gvResults.Rows[0].Visible = false;
        }
        if(dt.Rows.Count > 0 )
        {
            //DataSource is not empty
            gvResults.DataSource = dt;
            gvResults.DataBind();
        }
        else
        {
            //DataSource empty, add dummy row
            dt.Rows.Add(dt.NewRow());
            gvResults.DataSource = dt;
            gvResults.DataBind();
           //Make dummy row invisible
            gvResults.Rows[0].Visible = false;
        }
