Telerik RadGrid 更新命令未触发

Question

所以，我有一个具有典型编辑安排的 RadGrid，它正在工作……但现在不行。永远不要触发 UpdateCommand 事件，在那里设置一个断点并且它没有被到达。让我发疯，因为它一直工作得很好，我想不出我做过的任何事情会导致它。当我单击编辑时，表单打开得很好，取消按钮有效，但更新命令永远不会触发。 在网格中我有：

OnUpdateCommand="pendingVehiclesRadGrid_UpdateCommand" 

And in my code behind I have:

 protected void pendingVehiclesRadGrid_UpdateCommand(object source, GridCommandEventArgs e)
{
blah blah
}

看起来很简单，但正如我所说......什么都没有。如果有新视野的人能提出建议，我将一如既往地感激不尽。

编辑以添加 XML：

我已经尝试重构您的示例并且成功了：

ASPX：

<telerik:RadGrid ID="pendingVehiclesRadGrid" runat="server" AutoGenerateColumns="False"
    CellSpacing="0" GridLines="None" AllowPaging="True"
    DataMember="ID"
    OnNeedDataSource="pendingVehiclesRadGrid_NeedDataSource"
    OnUpdateCommand="pendingVehiclesRadGrid_UpdateCommand" PageSize="20"
    OnItemCommand="pendingVehiclesRadGrid_ItemCommand">
    <MasterTableView DataKeyNames="status,charity,make,model,year,vin,date,id,salePrice,bid,note"
        EditMode="EditForms">

        <CommandItemSettings ExportToPdfText="Export to PDF"></CommandItemSettings>

        <RowIndicatorColumn Visible="True" FilterControlAltText="Filter RowIndicator column" HeaderStyle-Width="20px" />

        <ExpandCollapseColumn Visible="True" FilterControlAltText="Filter ExpandColumn column" HeaderStyle-Width="20px" />

        <Columns>
            <telerik:GridButtonColumn CommandName="History" Text="History" UniqueName="detailBtn" HeaderText="History" HeaderButtonType="PushButton" AutoPostBackOnFilter="True" />

            <telerik:GridBoundColumn HeaderText="Year" ItemStyle-Width="140px" FilterControlAltText="Filter column2 column" UniqueName="column2" DataType="System.Int32" DataField="year" />
            <telerik:GridBoundColumn HeaderText="Make" ItemStyle-Width="140px" FilterControlAltText="Filter column column" UniqueName="column" DataType="System.String" DataField="make" />

            <telerik:GridBoundColumn HeaderText="Sale Price" ItemStyle-Width="140px" FilterControlAltText="Filter column1 column" UniqueName="column6" DataType="System.Decimal" DataField="salePrice" DataFormatString="{0:C}" Display="False" />
            <telerik:GridBoundColumn HeaderText="Notes" ItemStyle-Width="140px" FilterControlAltText="Filter column1 column" UniqueName="unsoldNotesColumn" DataType="System.String" DataField="note" Display="True" />
            <telerik:GridTemplateColumn HeaderText="Latest Status" ItemStyle-Width="240px">

                    <%#DataBinder.Eval(Container.DataItem, "Status")%>

                    <%-- I have to outcomment this, because I don't have any LinqDataSource1 available --%>
                    <%--<telerik:RadComboBox RenderMode="Lightweight" runat="server" ID="pendingVehiclesRadGridupdateComboBox" DataTextField="Status"
                        DataValueField="ID" DataSourceID="LinqDataSource1">
                    </telerik:RadComboBox>--%>
                </EditItemTemplate>
            </telerik:GridTemplateColumn>

            <telerik:GridEditCommandColumn FooterText="EditCommand footer" UniqueName="pendingVehiclesRadGridEditCommandColumn" HeaderText="Edit" HeaderStyle-Width="100px" UpdateText="Update" />
        </Columns>

        <EditFormSettings EditColumn-DataType="System.String">
            <EditColumn FilterControlAltText="Filter EditCommandColumn column" />
        </EditFormSettings>
    </MasterTableView>

    <FilterMenu EnableImageSprites="False" />
</telerik:RadGrid>

代码隐藏：

protected void pendingVehiclesRadGrid_NeedDataSource(object sender, GridNeedDataSourceEventArgs e)
{
    this.pendingVehiclesRadGrid.DataSource = new List<object> {
        new {
            id = 1,
            charity = "charity1",
            vin = "vin1",
            year = 2015,
            make = "make1",
            model = "model1",
            date = DateTime.Now.AddYears(-1),
            bid = (decimal)12000.00,
            salePrice = (decimal)14469.95,
            note = "a new car",
            Status = "NOT SOLD"
        },
        new {
            id = 2,
            charity = "charity2",
            vin = "vin2",
            year = 1967,
            make = "make2",
            model = "model2",
            date = DateTime.Now,
            bid = (decimal)14000.00,
            salePrice = (decimal)19469.95,
            note = "an oldtimer",
            Status = "NOT SOLD"
        }
    };
}

protected void pendingVehiclesRadGrid_UpdateCommand(object sender, GridCommandEventArgs e)
{
    Console.WriteLine("This will be reached!"); // I've put the breakpoint here
}

protected void pendingVehiclesRadGrid_ItemCommand(object sender, GridCommandEventArgs e)
{

}

如您所见，我删除了一些不必要的标记，但这不是问题来源。我还必须删除EditItemTemplate 中的RadComboBox，因为我不能使用LinqDataSource1。

但要明确一点：我不知道为什么它对你不起作用，但我希望这能帮助你跟踪问题。

也尝试对你的 RadComboBox 发表评论。看看这是否是问题的根源。如果没有，您可能会在后面的代码中犯任何错误，可能是在数据绑定本身上。

如果您无法跟踪问题，请尝试在自己的解决方案中隔离问题。通过使用硬编码数据（如我的示例）将其确定下来。如果问题仍然存在，请发布您的测试解决方案中的所有代码或共享解决方案本身没有 Telerik 组件 (!)

@modiX 好的...再次真诚地感谢您的帮助。我还没有弄清楚这个问题，但是在用头撞了两天之后，我意识到在某一时刻，这一切都奏效了，也许在我在表格上所做的所有其他工作中的某个地方，我把它弄坏了，但没有直到为时已晚才意识到这一点。因此，我开始一次剪切三个网格中的每一个及其后面的代码，并将它们粘贴到一个新的页面中。而且......他们工作。

不知道是什么“功能”导致它们崩溃，但我愿意称之为胜利并继续前进……更谨慎；）

再次感谢您的宝贵时间和热心帮助！
