usage of GridView.OnRowUpdating

[Jeff]

hi

asp.net 2.0

I'm having problem updating a GridView. The problems is that the website
complains it don't find the update method. The problem is caused by the
updateparameters. The UpdateMethod take 3 parameters: Id (DataKeyNames),
Kode and Desc.

Here is the markup of both GridView and ObjectDataSource:
<asp:GridView ID="gvwPhoneType"
runat="server" OnRowUpdating="gvwPhoneType_RowUpdating"
OnRowDataBound="gvwPhoneType_DataBound"
OnRowEditing="gvwPhoneType_RowEditing"
OnRowDeleting="gvwPhoneType_RowDeleting"
DataSourceID="odsPhoneType" DataKeyNames="Id"
OnRowCancelingEdit="gvwPhoneType_RowCancelingEdit"
AutoGenerateEditButton="true"
ShowFooter="true"
AutoGenerateColumns="false" >
//columns go here

<asp:ObjectDataSource ID="odsPhoneType"
TypeName="DAL.SqlServer2005.SqlSupportProvider"
SelectMethod="getPhoneTypes" UpdateMethod="updatePhoneType"
InsertMethod="insertPhoneType" runat="server">
<UpdateParameters>
<asp:Parameter Type="Char" Name="type" Direction="Input" />
<asp:Parameter Type="string" Name="desc" Direction="Input" />
</UpdateParameters>
<InsertParameters>
<asp:Parameter Type="Char" Name="Type" />
<asp:Parameter Type="string" Name="Desc" />
</InsertParameters>
</asp:ObjectDataSource>

UpdateMethod:
public override void updatePhoneType(int id, char type, string desc)

So I thought about manually calling the UpdateMethod from the OnRowUpdating
event. Possible? any suggestions?
