Telerik 控件在执行RadGrid ItemCommand（）后不更新

我有一个RadGrid，它在单击行时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。My-Radgrid1-在首次访问页面时使用默认的select all sqldatasource，然后，您可以通过单击另一个Radgrid1来过滤Radgrid1项。它也有一个不同类别的列表

发生的情况是： 1.行被单击 2.radgrid1_项命令。。。，。。。被执行

编辑后，以下代码更改为实际代码：

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();
}

三,。页面刷新，RadGrid1中有旧值+标签有默认的测试文本

我已经阅读了所有关于这个问题的Telerik API，并尝试了previuos解决方案，但徒劳无功。 我有什么遗漏吗？还是忘了做？有人知道为什么会这样吗

关于AJAX，我的经理已经指示我不要在这个页面上使用AJAX。希望我的英语足够好来解决这个问题

编辑：我得到了一个关于我的查询的PM，我已经在SQLServerManagementStudio中对它进行了测试，它功能齐全。我现在正在添加包含此控件的div的aspx代码，外部有标签、一些aspbutton，与此div的内容无关

第二次编辑时，先前的网格更改为RadMenu。Codebehind仍然相同，只是与新菜单关联

      <div>
 <table>
    <tr>

        <td><asp:UpdatePanel ID="panelGetTeGjitha"  runat="server" UpdateMode="Conditional" ChildrenAsTriggers="false" >

你好，杰耶什，谢谢你的回复。在我看到你的答案后，我注意到我的两个网格在不同的UpdatePanel-s中，但我将它们都放在同一个UpdatePanel中，运行测试，但它不起作用。但我必须补充一点，在同一个UpdatePanel中移动它们之后，在回发RadGrid1具有旧值之后，我意外地点击了刷新按钮，这次它显示了过滤后的数据。我想我缺少了一些设置类型，你知道吗？你能提供你的aspx页面代码吗？所以我们可以解决这个问题。我更新了上面的代码，我离开了网格，我想在RadMenu的UpdatePanel上更新它。您好，您的方法工作正常，但是在回发后，更改不会显示，它显示您是否刷新了页面。我想我得从头再做一遍。非常感谢您的时间。我已经检查了您对上述代码的要求，它工作正常。请检查以上代码在单独的页面，让我知道它的工作与否。

  protected void MenuKampionati_ItemClick(object sender, RadMenuEventArgs e)
{

    GridNdeshjet.Rebind();
}

protected void GridNdeshjet_NeedDataSource1(object sender, GridNeedDataSourceEventArgs e)
{

    string strID = string.Empty; // just For Test


    if (MenuKampionati.SelectedItem != null)
    {
        // Get Selected Records  as per item selected in RadMenu

        //Case = 2;
        //Arg1 = "%%";
        string Arg2 = MenuKampionati.SelectedItem.Value;
        //string query = "EXECUTE get_ndeshje_kot31 " + Case.ToString() + ", '" + Arg1 + "', '" + Arg2 + "', 0";
        //SqlDataSource MyDataSource = new SqlDataSource(ConfigurationManager.ConnectionStrings["basteConnection
        strID = MenuKampionati.SelectedItem.Value; // just For Test
    }
    else
    {
        // Get All records From DB
    }


    // just For Test
    dynamic data = new[] {
            new { ID = 1, Name ="Name" + strID},
            new { ID = 2, Name ="Name"+ strID},
            new { ID = 3, Name ="Name"+ strID},
            new { ID = 4, Name ="Name"+ strID},
            new { ID = 5, Name ="Name"+ strID},
            new { ID = 6, Name = "Name"+ strID}
        };


    GridNdeshjet.DataSource = data;
}
