ASP.NET Webforms Gridview 页脚

Question

在 ASP.NET 网络表单中，有没有办法配置 GridView 的 FooterTemplate 以允许页脚溢出，但也保留上面的列宽度，如下所示？就像现在一样，任何页脚溢出也会拉伸其上方的单元格。

Answer 1

您可以使用gridview_rowcreated() 事件来做到这一点。

如果允许行跨度和列具有所需的列和行

根据您的要求修改它。

protected void GridView1_RowCreated(object sender, GridViewRowEventArgs e)
{
    if (e.Row.RowType == DataControlRowType.Footer)
    {
        GridView FooterGrid = (GridView)sender;
        GridViewRow FooterRow = new GridViewRow(0, 0, DataControlRowType.Footer, DataControlRowState.Insert);
        TableCell Cell_Footer = new TableCell();
        Cell_Footer.Text =""; // As per your requirement
        Cell_Footer.HorizontalAlign = HorizontalAlign.Center;
        Cell_Footer.ColumnSpan = 2;
        HeaderRow.Cells.Add(Cell_Footer);

        Cell_Footer = new TableCell();
        Cell_Footer.Text = ""; // As per your requirement
        Cell_Footer.HorizontalAlign = HorizontalAlign.Center;
        Cell_Footer.ColumnSpan = 1;
        Cell_Footer.RowSpan = 2;
        FooterRow.Cells.Add(Cell_Footer);

        Cell_Footer = new TableCell();
        Cell_Footer.Text = ""; // as per your requiremnt
        Cell_Footer.HorizontalAlign = HorizontalAlign.Center;
        Cell_Footer.ColumnSpan = 3;
        FooterRow.Cells.Add(Cell_Footer);

        GridView1.Controls[0].Controls.AddAt(0, FooterRow);

    }
}
