Below code sample shows hows how to Merge or combine two GridView Header in asp.net. the code i have used is C#. With this you can merge two pr more column with minimal code changes. Lets see the code.

All we nee to write the code in ItemCreated event of the DataGrid

protected void myGridView_ItemCreated(object sender, GridViewRowEventArgs e)
    {
        if (e.Row.RowType == DataControlRowType.Header)
        {
            //custom header.
            GridView gvHeader = (GridView)sender;
            GridViewRow gvHeaderRow = new GridViewRow(0, 0, DataControlRowType.Header, DataControlRowState.Insert);
            TableCell tc1 = new TableCell();

            // First column
            tc1.Text = "Merged Column1";
            tc1.ColumnSpan = 2;
            tc1.BackColor = System.Drawing.Color.Brown;
           
            gvHeaderRow.Cells.Add(tc1l);

             // Second  column 

            tc1 = new TableCell();
            tc1.Text = "Merged Column2";
            tc1.ColumnSpan = 2;
            gvHeaderRow.Cells.Add(tc1);

           gvHeader.Controls[0].Controls.AddAt(0, gvHeaderRow);

          }
}
