你可以顯示你正在做數據綁定的代碼？ – 2010-03-17 07:00:09

通過製作函數，在頁面加載事件上的codebehind上進行數據綁定。 – sikender 2010-03-17 07:13:58

應該是這樣......

PostBackUrl='<%# Eval("SystemEmailID", "Edit_SyatemEmails.aspx?id={0}" 
+ "&blogentry=" + Request.QueryString["edit"]) %>'

我會建議你做在後面的代碼。在GridView RowCreated事件：

protected void GridView_OnRowCreated(Object sender, GridViewRowEventArgs e) 
{ 
    if(e.Row.RowType == DataControlRowType.DataRow) 
    { 
     (e.Row.FindControl("ibtnEdit") as ImageButton). PostBackUrl = "~/Edit_SyatemEmails.aspx?blogentry=edit&id=" + DataBinder.Eval(e.Row.DataItem, "SystemEmailID")) 
    } 
}
