Thanks Yudi,

thankyou for the help..

I require some logic to be evaluated before a delete occurs, which requires some of the bound columns (hidden) to be passed into the delete sproc too. This is where the challenge arises as i currently cannot get the hidden columns to be passed in, even though they are in the delete element list (see below)

Could you please provide an example of this also.

David

<RootTable DataKeyField="MyId">
<Columns>
<ISWebGrid:WebGridColumn Caption="HiddenId" DataMember="HiddenId" DataType="System.Guid" Name="HiddenId" Width="100px" Visible="false" EditType="NoEdit" >
.....
......

<DeleteParameters>
<asp:Parameter Name="HiddenId" Type="String" />
</DeleteParameters>
