Answer 1

您可以通過GridView的RowCreated中的代碼隱藏手動生成頁腳。

例如：

protected void GridView1_RowCreated(object sender, System.Web.UI.WebControls.GridViewRowEventArgs e) 
{ 
    if (e.Row.RowType == DataControlRowType.Footer) { 
     var grid = (GridView)sender; 
     Label lbl1 = new Label(); 
     Label lbl2 = new Label(); 
     TableCell footerCell = new TableCell(); 
     TableCell cell1 = new TableCell(); 
     TableCell cell2 = new TableCell(); 
     TableRow footerRow = new TableRow(); 
     Table footerTable = new Table(); 
     e.Row.Cells.Clear(); 
     footerCell.Controls.Add(footerTable); 
     footerTable.Rows.Add(footerRow); 
     lbl1.ID = "lbl1"; 
     lbl2.ID = "lbl2"; 
     cell1.Controls.Add(lbl1); 
     cell2.Controls.Add(lbl2); 
     footerRow.Cells.Add(cell1); 
     footerRow.Cells.Add(cell2); 
     e.Row.Cells.Add(footerCell); 
    } 
} 

protected void GridView1_RowDataBound(object sender, System.Web.UI.WebControls.GridViewRowEventArgs e) 
{ 
    if (e.Row.RowType == DataControlRowType.Footer) { 
     DataRow row = getFooterSource().Rows[0]; 
     var lbl1 = (Label)e.Row.FindControl("lbl1"); 
     var lbl2 = (Label)e.Row.FindControl("lbl2"); 
     lbl1.Text = row["Col1"]; 
     lbl2.Text = row["Col2"]; 
     e.Row.Cells[0].ColumnSpan = ((DataTable)((GridView)sender).DataSource).Columns.Count; 
    } 
} 

//get some mock-data 
private DataTable getFooterSource() 
{ 
    DataTable tblFooter = new DataTable("Footer"); 
    tblFooter.Columns.Add(new DataColumn("Col1", typeof(string))); 
    tblFooter.Columns.Add(new DataColumn("Col2", typeof(string))); 
    var footerRow = tblFooter.NewRow(); 
    footerRow(0) = "first column's value"; 
    footerRow(1) = "second column's value"; 
    tblFooter.Rows.Add(footerRow); 
    return tblFooter; 
}
