虎搞瞎搞

參考:http://blog.xuite.net/yan.kee/CSharp/14844624?ref=rel

解法如下

C# 加上下面的CODE就OK了  

public override void VerifyRenderingInServerForm(Control control)
        {
        }

下面為過濾物件的Function 在

this.ClearControls(dg); //這邊叫用會過濾掉物件資料
dg.RenderControl(oHtmlTextWriter);

private void ClearControls(Control control)
    {
        for (int i = control.Controls.Count - 1; i >= 0; i--)
        {
            ClearControls(control.Controls[i]);
        }

        if (!(control is TableCell))
        {
            if (control.GetType().GetProperty("SelectedItem") != null)
            {
                LiteralControl literal = new LiteralControl();
                control.Parent.Controls.Add(literal);
                try
                {
                    literal.Text = (string)control.GetType().GetProperty("SelectedItem").GetValue(control, null);
                }
                catch
                {

                }

                control.Parent.Controls.Remove(control);
            }

            else

                if (control.GetType().GetProperty("Text") != null)
                {
                    LiteralControl literal = new LiteralControl();
                    control.Parent.Controls.Add(literal);
                    literal.Text = (string)control.GetType().GetProperty("Text").GetValue(control, null);
                    control.Parent.Controls.Remove(control);
                }
        }
        return;
    }
