c# - asp.net动态添加GridViewRow

Question

我看过这篇文章How to programmatically insert a row in a GridView?但我无法让它添加一行我在 RowDataBound 上尝试过，然后在 DataBound 事件上尝试过，但它们都不起作用这里是我的代码，如果有人可以告诉我如何动态地添加一行到 GridView 的末尾而不是 Footer 那反正我的代码不起作用

protected void CustomGridView_DataBound(object sender, EventArgs e)
{
    int count = ((GridView)sender).Rows.Count;
    GridViewRow row = new GridViewRow(count+1, -1, DataControlRowType.DataRow, DataControlRowState.Insert);
    //lblCount.Text = count.ToString();
    // count is correct
    // row.Cells[0].Controls.Add(new Button { Text="Insert" });
    // Error Here adding Button 
    Table table = (Table)((GridView)sender).Rows[0].Parent;
    table.Rows.Add(row);
    // table doesn't add row          
}

使用 RowDataBound 事件，将任何控件添加到 TableCell，并将 TableCell 添加到 GridViewRow。最后将 GridViewRow 添加到 GridView 的指定索引处:

protected void gv_RowDataBound(object sender, GridViewRowEventArgs e) 
{ 
    GridViewRow row = new GridViewRow(e.Row.RowIndex+1, -1, DataControlRowType.DataRow, DataControlRowState.Insert); 
    TableCell cell = new TableCell();
    cell.ColumnSpan = some_span;
    cell.HorizontalAlign = HorizontalAlign.Left;

    Control c = new Control(); // some control
    cell.Controls.Add(c);
    row.Cells.Add(cell);

    ((GridView)sender).Controls[0].Controls.AddAt(some_index, row);
} 

这可能不是您所需要的，但它应该给您一个想法。
