Question

I have a list view with 5 columns which is populated via a stored procedure. That is displaying fine.
I also have a Delete method which only takes in one int (the ID) but I am not sure how to define this method in the dataSource of the listview.

I keep getting an error that there is no Delete method which takes in 5 paramteres (the listview’s column names) which of course there isn’t. There is one which takes in 1 int parameter, see below.

I think there must be some error with the DataSource Delete method declaration, can anyone tell?

<asp:ObjectDataSource ID="userListDataSource" runat="server" 
            SelectMethod="GetUserList" TypeName="UserManagerBO" 
            DeleteMethod="DeleteUser">
            <DeleteParameters>
                <asp:Parameter Name="userID" Type="Int32"/>
            </DeleteParameters>
        <SelectParameters>
            <asp:ControlParameter DefaultValue="61" Name="userID" Type="Int32" 
                ControlID="lbUsers" PropertyName="SelectedValue" />
        </SelectParameters>
</asp:ObjectDataSource>

The method to delete is DeleteUser(int userID) and it seems to always look at the SelectParameters, even for my Delete method.

Try dont provide parameter to the deletemethod, by doing this you can get the entire object selected for delete as a parameter. In Delete method,

Public Void DeleteUser(User usr)
{
        //delete user of usr.UserID
}
