Question

我的Usercontrol＆amp;中有一个Listview 1个与ListView绑定的objectdatasource。现在在objectdatasource的Deletemethod我已经将businessobject作为参数，但在运行时我没有在我的businessobject的属性中获得价值......

我还尝试在ItemTemplate中使用“Bind”而不是“eval”。但是在objectdatasource的Deletecommand中提供的DeleteMethod中没有在运行时获取任何值... 任何人都可以帮助了解天气我正在做什么或什么？

我的Listview的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>

删除objectdata中使用的方法 source的Deletecommand

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

尝试将业务对象键字段（例如id，key ...）添加到listview datakeynames属性。通过这样做，您至少可以在删除事件中获取键值。

带有objectdatasource的Listview删除不起作用
