Listview with objectdatasource Delete not working

Question

i have one Listview in my Usercontrol & 1 objectdatasource binded with the ListView. now in objectdatasource's Deletemethod i have taken businessobject as argument but at runtime i am not getting value in my businessobject's properties...

i also tried to use "Bind" instead of "eval" in ItemTemplate. but not getting any value at runtime in my DeleteMethod provided in objectdatasource's Deletecommand... can anybody help to know weather i am mising anything or what?

my Listview's ItemTemplate

 <ItemTemplate>
            <asp:HiddenField ID="hidUserAchievementInfoId" runat="server" Value='<%# Bind("UserAchievementInfoId") %>' />
            <asp:HiddenField ID="hidUserIdField" runat="server" Value='<%# Bind("UserId") %>' />
            <tr>
                <td class="style1">
                    <asp:Label ID="AwardLabel" runat="server" Text="Award "></asp:Label>
                </td>
                <td>
                    <asp:Label ID="lblAward" runat="server" Text='<%# Bind("Awards") %>'></asp:Label>
                </td>
            </tr>
            <tr>
                <td class="style1">
                    <asp:Label ID="FieldofAwardLabel" runat="server" Text="Field of Award "></asp:Label>
                </td>
                <td>
                    <asp:Label ID="lblFieldofAward" runat="server" Text='<%# Bind("FieldofAward") %>'></asp:Label>
                </td>
            </tr>
            <tr>
                <td class="style1">
                    <asp:Label ID="TournamentLabel" runat="server" Text="Tournament "></asp:Label>
                </td>
                <td>
                    <asp:Label ID="lblTournament" runat="server" Text='<%# Bind("Tournament") %>'></asp:Label>
                </td>
            </tr>
            <tr>
                <td class="style1">
                    <asp:Label ID="AwardYearLabel" runat="server" Text="Award Year "></asp:Label>
                </td>
                <td>
                    <asp:Label ID="AwardYear" runat="server" Text='<%# Bind("AwardYear") %>'></asp:Label>
                </td>
            </tr>
            <tr>
                <td class="style1">
                    <asp:Label ID="AwardDescriptionLabel" runat="server" Text="Description "></asp:Label>
                </td>
                <td>
                    <asp:Label ID="lblAwardDescription" runat="server" Text='<%# Bind("AwardDescription") %>'></asp:Label>
                </td>
            </tr>
            <tr>
                <td class="style1">
                    <asp:LinkButton ID="EditButton" runat="server" CommandName="Edit" Text="Edit"></asp:LinkButton>
                </td>
                <td>
                    <asp:LinkButton ID="DeleteButton" runat="server" CommandName="Delete" Text="Delete"></asp:LinkButton>
                </td>
            </tr>
        </ItemTemplate>

Delete Method used in objectdata source's Deletecommand

    public void DeleteUserAchievementInfo(UserAchivementInfoBO BOInstance)
    {
        try
        {
    Int64 UserAchievementInfoId=BOInstance.UserAchievementInfoId
            objUserBasicInfoServiceClient.DeleteUserAchievementInfo(UserAchievementInfoId);
        }
        catch (Exception ex)
        {
            HandleException.LogError(ex);
        }
    }

How about showing us your code, so we can see if something is wrong there? — Oded

Try to add the business object key field(e.g id, key...) to the listview datakeynames property. By doing this, you can at least get the key value in the deleting event.
