您需要的DataKeyNames添加到您的GridView这样的：

<asp:GridView ID="yourGridViewId" DataKeyNames="REF" ... > 
... 
</asp:GridView>

http://msdn.microsoft.com/en-us/library/system.web.ui.webcontrols.gridview.datakeynames.aspx

You must set the DataKeyNames property in order for the automatic update and delete features of the GridView control to work. The values of these key fields are passed to the data source control in order to specify the row to update or delete.

添加ref参数作为QueryStringParameter

<SelectParameters> 
    <asp:QueryStringParameter Name="ref" QueryStringField="ref" /> 
</SelectParameters>
