誰能幫助我?如何在asp.net驗證之前更新面板。使用telerik

我有問題。當更改telerik的radcombobox時,如此驗證文本框句柄。但是我想驗證只在點擊button1時才能處理。

follown代碼:

asp.net

<asp:ScriptManager ID="ScriptManager1" runat="server"></asp:ScriptManager> 
     <telerik:RadAjaxManager ID="RadAjaxManager1" runat="server"> 
      <AjaxSettings> 
       <telerik:AjaxSetting AjaxControlID="RadComboBox1"> 
        <UpdatedControls> 
         <telerik:AjaxUpdatedControl ControlID="RadComboBox1" /> 
         <telerik:AjaxUpdatedControl ControlID="Label1" /> 
        </UpdatedControls> 
       </telerik:AjaxSetting> 
      </AjaxSettings> 
     </telerik:RadAjaxManager> 
     <asp:Panel ID="Panel1" runat="server"> 
     <asp:Label ID="Label1" runat="server" Text="Label"></asp:Label> 
     <telerik:RadComboBox ID="RadComboBox1" AutoPostBack="true" runat="server" DataSourceID="SqlDataSource1" DataTextField="cg_id" OnSelectedIndexChanged="RadComboBox1_SelectedIndexChanged"></telerik:RadComboBox> 
     <asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:TravelConnectionString %>" SelectCommand="SELECT * FROM [Categorys_Group]"></asp:SqlDataSource> 
      </asp:Panel> 
     <telerik:RadTextBox ID="RadTextBox1" runat="server"></telerik:RadTextBox> 
     <asp:RequiredFieldValidator ID="TextBoxRequiredFieldValidator" runat="server" Display="Dynamic" 
        ControlToValidate="RadTextBox1" ErrorMessage="Không được để trống!" ForeColor="Red"></asp:RequiredFieldValidator> 

後面的代碼:

protected void RadComboBox1_SelectedIndexChanged(object sender, Telerik.Web.UI.RadComboBoxSelectedIndexChangedEventArgs e) 
     { 
      Label1.Text = RadComboBox1.SelectedIndex.ToString(); 
     } 

現在,我想改變的時候驗證RadComboBox1,TextBoxRequiredFieldValidator沒有處理程序。它只在點擊按鈕時處理。

我該怎麼辦? 謝謝幫幫我!

請嘗試使用下面的代碼片段。

<telerik:RadComboBox CausesValidation="false" ID="RadComboBox1" AutoPostBack="true" runat="server" DataSourceID="SqlDataSource1" DataTextField="cg_id" OnSelectedIndexChanged="RadComboBox1_SelectedIndexChanged"></telerik:RadComboBox>

現在,我知道它是如何做到的。

我添加ValidationGroup="SelectionFormValidationGroup"進行控件驗證。
