执行 RadGrid ItemCommand() 后控件未更新

Question

我有一个 RadGrid，它在 RowClick 上应该向服务器发送一个特定的值。由于页面的性质，所有事件都在服务器端处理。我的 -Radgrid1- 在第一次访问页面时使用默认的“选择”所有 sqldatasource，然后，您可以通过单击另一个 RadGridAnother 来过滤 RadGrid1 项目。其中还有一个不同类别的列表。

会发生什么： 1.点击行 2. radgrid1_ItemCommand(...,...) 被执行。

下面的代码在编辑后变为实际：

protected void MenuKampionati_ItemClick(object sender, RadMenuEventArgs e)
{
    Case = 2;
    Arg1 = "%%";
    Arg2 = e.Item.Value;
    string query = "EXECUTE get_ndeshje_kot31 " + Case.ToString() + ", '" + Arg1 + "', '" + Arg2 + "', 0";
    SqlDataSource MyDataSource = new SqlDataSource(ConfigurationManager.ConnectionStrings["basteConnectionString"].ConnectionString, query);
    this.GridNdeshjet.DataSource = MyDataSource;
    this.GridNdeshjet.DataBind();
}

3。页面“刷新”并且 RadGrid1 包含旧值 + 标签具有默认测试文本。

我已经阅读了有关此问题的所有 Telerik API，并徒劳地尝试了以前的解决方案。 有什么我想念的吗？还是忘记做？有谁知道为什么会发生这种情况？

关于 AJAX，我的经理已指示我不要“AJAX”此页面。希望我的英语足够好解决这个问题。

编辑：我收到了关于我的查询的 PM，我已经在 sqlserver 管理工作室中对其进行了测试，它功能齐全。我现在正在添加包含此控件的 div 的 aspx 代码，外面有标签，一些 aspbutton，仅此而已，与此 div 的内容无关。

第二次编辑，以前的网格更改为 RadMenu。 Codebehind 还是一样的，只是与新的 Menu 相关联。
