Updating is not supported by ObjectDataSource 'ObjectDataSource1' unless the UpdateMethod is specified.

Hi,

Can someone help me out regarding this error. As relatively new to .nettiers can somebody tells where to write the update method.I am using the view to retrieve the data. I am using service layer to add my custom methods as per my requirement. Also please give some suggestion about writing my own insert method.

<asp:DropDownList ID="DropDownList1" runat="server" AutoPostBack="True" DataSourceID="pp" DataTextField="Prj_Name" DataValueField="Prj_ID" OnSelectedIndexChanged="DropDownList1_SelectedIndexChanged">

</asp:DropDownList><br />

<data:ProjectsDataSource runat="server" SelectMethod="GetPaged" ID="pp" EnablePaging="True" EnableSorting="True" EnableTransaction="False">

<DeepLoadProperties Method="IncludeChildren" Recursive="False">

</DeepLoadProperties>

</data:ProjectsDataSource>

If you generate webadmin you'll be able to see, how to populate GridView using Typed DataSource controls and also edit record in-line or via FormView
