Question

我有以下Telerik RadGrid，我在C＃中使用它：

<MasterTableView Width="100%" EditMode= "InPlace" ClientDataKeyNames="menuID" CommandItemDisplay= "Top">
    <Columns>
        <telerik:GridBoundColumn DataField="Name" HeaderText="Name" SortExpression="Name" UniqueName="Name"></telerik:GridBoundColumn>
        <telerik:GridTemplateColumn UniqueName="Type" HeaderText="Type">
            <ItemTemplate>
                <asp:TextBox ID="Type" Text='<%# DataBinder.Eval(Container.DataItem, "Type") %>' runat="server"></asp:TextBox>
            </ItemTemplate>
            <EditItemTemplate>
            </EditItemTemplate>
        </telerik:GridTemplateColumn>
        <telerik:GridTemplateColumn UniqueName="List" HeaderText="List">
            <ItemTemplate>
                <asp:CheckBox ID="List" runat="server" Checked='<%# DataBinder.Eval(Container.DataItem, "List") %>' />
            </ItemTemplate>
            <EditItemTemplate>
            </EditItemTemplate>
        </telerik:GridTemplateColumn>
        <telerik:GridTemplateColumn UniqueName="loadAtStart" HeaderText="loadAtStart">
            <ItemTemplate>
                <asp:CheckBox ID="loadAtStart" runat="server" Checked='<%# DataBinder.Eval(Container.DataItem, "loadAtStart") %>' />
            </ItemTemplate>
            <EditItemTemplate>
            </EditItemTemplate>
        </telerik:GridTemplateColumn>
    </Columns>
</MasterTableView>

网格填充数据，并在编辑数据时正常工作。

但是，当我单击Telerik提供的“添加新记录”按钮时，会添加一个空行，而不会在添加的新行中编辑列中的任何TextBox或CheckBox。这只是一个空行。我假设我必须在被调用的ItemDataBound事件中动态创建控件，但我没有找到实际的代码。

我该如何解决这个问题？

请尝试使用以下代码段。

    I have modified the parameters according to my requirement and also included all CURD operations.
