我正在使用Ext.NET和VS2008，ASP.NET。我有一个独特的问题，我无法找到任何解决方案。
有一个GridPanel，在TopBar中有一个删除按钮。 Grid使用RowSelection模型。选择行后，用户单击“删除”按钮。引发客户端事件以确认以下是代码段
<ext:Button ID="btnDelete" runat="server" Text="Delete" Icon="Delete">
<DirectEvents>
<Click OnEvent="Evt_Delete">
<ExtraParams>
<ext:Parameter Name="recordId" Value="(#{grdSanction}).selModel.getSelected().data.VoucherID" Mode="Raw" />
</ExtraParams>
<Confirmation Message="Do you really want to delete sanction?" ConfirmRequest="true"/>
</Click>
</DirectEvents>
</ext:Button>
但问题是我点击是后我得到以下消息基本上是500内部服务器错误。
以下是我在Fiddler中找到的内容：
结果协议主机URL正文缓存内容类型进程注释自定义
1 500 HTTP onyx /pages/sanction.aspx?_dc=1337773867270 4,268 private text / html; charset = utf-8 chrome：920
VS2008的调试器不起作用，因为后面的代码上的事件永远不会引发。 工具栏上的其他按钮工作得很好。有谁知道我在这里失踪了什么？
答案 0 :(得分：1)
我认为你只需要删除#{grdSantion}周围的圆括号。
// Not OK
(#{grdSanction}).selModel.getSelected().data.VoucherID
// OK
#{grdSanction}.selModel.getSelected().data.VoucherID
以下示例演示了完整方案，并且似乎可以按照您的要求运行。
