Merge Merging GridView Header Columns Multiple Headers ASP.NET

问题

protected void GrdLeaveMaster_RowCreated(object sender, GridViewRowEventArgs e)
{
    if (e.Row.RowType == DataControlRowType.Header)
    {
        GridView HeaderGrid = (GridView)sender;
        GridViewRow HeaderGridRow =
        new GridViewRow(2, 2, DataControlRowType.EmptyDataRow,
        DataControlRowState.Insert);
        TableCell HeaderCell = new TableCell();
        HeaderCell.Text = "PaidLeave";
        HeaderCell.ColumnSpan = 2;
        HeaderGridRow.Cells.Add(HeaderCell);

        HeaderCell = new TableCell();
        HeaderCell.Text = "accumulated";
        HeaderCell.ColumnSpan = 2;
        HeaderGridRow.Cells.Add(HeaderCell);

        GrdLeaveMaster.Controls[0].Controls.AddAt(0, HeaderGridRow);
    }
}

I want header does not show in first column it shows on second column

回答1:

TableCell HeaderCell = new TableCell();
HeaderCell.Text = "";
HeaderCell.ColumnSpan = 1;
HeaderGridRow.Cells.Add(HeaderCell);

TableCell HeaderCell = new TableCell();
HeaderCell.Text = "PaidLeave";
HeaderCell.ColumnSpan = 1;
HeaderGridRow.Cells.Add(HeaderCell);

hope it helps
