我正在使用Telerik Radgrid作为我的aspx页面。我在这里上传了截图。这里的问题是，如果radgrid中没有项目，则“没有要显示的记录”消息应该扩展到网格的末尾。如果您看到屏幕截图，则网格中的消息框会在网格实际结束之前结束。我上传了我用过的代码。有什么出路吗？

答案 0 :(得分：0)
这就是NoRecordsTemplate的用途：
<telerik:RadGrid ID="RadGrid1" runat="server">
<MasterTableView ...>
<Columns>
...
</Columns>
<NoRecordsTemplate>
<!-- TEMPLATE FOR WHEN THERE ARE NO RECORDS -->
</NoRecordsTemplate>
</MasterTableView>
</telerik:RadGrid>
