行跨度和列跨度为ASP .NET的GridView在运行时

问题描述

如何在运行时做ROWSPAN和Columnspan在GridView的头？

How to do Rowspan and Columnspan in gridview header at run time?

目前我正与先创建一个表，然后将所有的行和列到它的复杂过程做。

currently I am doing it with a complex process of creating a table first and then adding all rows and columns into it.

后来做的GridView头的合并单元格并添加表到它的行创建的事件。

Later on doing colspan of gridview header and adding table into it on row created event.

code片断：

        Table headerTable = new Table();

    headerTable.CssClass = "tbl";
    headerTable.CellPadding = 1;
    headerTable.CellSpacing = 0;

    TableRow headerRow1 = new TableRow();

    TableHeaderCell headerTableCell = new TableHeaderCell();

    headerTableCell.RowSpan = 2;
    headerTableCell.Text = "SL No";
    headerTableCell.CssClass = "inputFromTo";

    headerRow1.Controls.Add(headerTableCell);

    headerTableCell = new TableHeaderCell();

    headerTableCell.ColumnSpan = 3;
    headerTableCell.Text = "MH1  <br> M. Mark";

    headerRow1.Controls.Add(headerTableCell);

    for (int i = 1; i <= Convert.ToInt16(txtHHColumn.Text); i++)
    {
        headerTableCell = new TableHeaderCell();

        headerTableCell.ColumnSpan = 3;
        headerTableCell.Text = "HH-" + i + "<br> M. Mark";

        headerRow1.Controls.Add(headerTableCell);
    }

    headerTableCell = new TableHeaderCell();

    headerTableCell.ColumnSpan = 3;
    headerTableCell.Text = "MH2 <br> M. Mark";

    headerRow1.Controls.Add(headerTableCell);

    TableRow headerRow2 = new TableRow();

    TableHeaderCell headerCell1;
    TableHeaderCell headerCell2;
    TableHeaderCell headerCell3;

    for (int i = 1; i < Convert.ToInt16(3 + Convert.ToInt16(txtHHColumn.Text)); i++)
    {
        headerCell1 = new TableHeaderCell();
        headerCell2 = new TableHeaderCell();
        headerCell3 = new TableHeaderCell();

        headerCell1.Text = "D Entry";
        headerCell1.CssClass = "inputFromTo";
        headerCell2.Text = "D Exit";
        headerCell2.CssClass = "inputFromTo";
        headerCell3.Text = "Slack";
        headerCell3.CssClass = "inputFromTo";

        headerRow2.Controls.Add(headerCell1);
        headerRow2.Controls.Add(headerCell2);
        headerRow2.Controls.Add(headerCell3);
    }

    headerTable.Rows.Add(headerRow1);
    headerTable.Rows.Add(headerRow2);

    GridViewRow HeaderRow = new GridViewRow(0, 0, DataControlRowType.Header, DataControlRowState.Insert);

    TableCell Cell_Header = new TableCell();

    Cell_Header.ColumnSpan = 10 + (Convert.ToInt16(txtHHColumn.Text) * 3);

    Cell_Header.Controls.Add(headerTable);
    HeaderRow.Cells.Add(Cell_Header);

    gvOfcManHole.Controls[0].Controls.AddAt(0, HeaderRow);

任何有比这更好的主意吗？

Anyone with better idea than this?

推荐答案

是的，我找到了解决我自己的问题。

Yes i found the solution to my own problem

protected void gvOfcManHole_RowCreated(object sender, GridViewRowEventArgs e)
{
    if (e.Row.RowType == DataControlRowType.Header)
    {
        GridViewRow headerRow1 = new GridViewRow(0, 0, DataControlRowType.Header, DataControlRowState.Insert);
        GridViewRow headerRow2 = new GridViewRow(0, 0, DataControlRowType.Header, DataControlRowState.Insert);

        TableHeaderCell headerTableCell = new TableHeaderCell();

        headerTableCell.RowSpan = 2;
        headerTableCell.Text = "SL No";

        headerRow1.Controls.Add(headerTableCell);

        headerTableCell = new TableHeaderCell();

        headerTableCell.ColumnSpan = 3;
        headerTableCell.Text = "MH1  <br> M. Mark";

        headerRow1.Controls.Add(headerTableCell);

        //for (int i = 1; i <= Convert.ToInt16(txtHHColumn.Text); i++)
        for (int i = 1; i <= 1; i++)
        {
            headerTableCell = new TableHeaderCell();

            headerTableCell.ColumnSpan = 3;
            headerTableCell.Text = "HH" + i + "<br> M. Mark";

            headerRow1.Controls.Add(headerTableCell);
        }

        headerTableCell = new TableHeaderCell();

        headerTableCell.ColumnSpan = 3;
        headerTableCell.Text = "MH2 <br> M. Mark";

        headerRow1.Controls.Add(headerTableCell);

        TableHeaderCell headerCell1;
        TableHeaderCell headerCell2;
        TableHeaderCell headerCell3;

        //for (int i = 1; i < Convert.ToInt16(3 + Convert.ToInt16(txtHHColumn.Text)); i++)
        for (int i = 1; i < Convert.ToInt16(3 + 1); i++)
        {
            headerCell1 = new TableHeaderCell();
            headerCell2 = new TableHeaderCell();
            headerCell3 = new TableHeaderCell();

            headerCell1.Text = "D Entry";
            headerCell2.Text = "D Exit";
            headerCell3.Text = "Slack";

            headerRow2.Controls.Add(headerCell1);
            headerRow2.Controls.Add(headerCell2);
            headerRow2.Controls.Add(headerCell3);
        }

        gvOfcManHole.Controls[0].Controls.AddAt(0, headerRow2);
        gvOfcManHole.Controls[0].Controls.AddAt(0, headerRow1);
    }
}
