更新面板导致验证问题。 [英] update panel causing validation problem.

问题描述

您好，



在我的项目中我使用的是更新面板，工作正常，但问题在于我的验证是在更新面板下。当我没有在我的文本框中提供任何数据并提交表格，验证无效。



请建议我一些解决方案并记住我不能添加任何DDL到我的申请。



提前致谢

请再次查看您的代码..以下是工作

please check your code once again.. below is working

<asp:ScriptManager ID="ScriptManager1" runat="server">
    </asp:ScriptManager>

<asp:UpdatePanel ID="UpdatePanel1" runat="server"><ContentTemplate>
      <asp:TextBox ID="TextBox1" runat="server"></asp:TextBox><asp:RequiredFieldValidator runat="server" ID="rfvtxt1" ControlToValidate="TextBox1" ErrorMessage="Required"></asp:RequiredFieldValidator>
      <asp:Button ID="Button1" runat="server" Text="Button" onclick="Button1_Click" />
      <asp:Label ID="Label1" runat="server" Text=""></asp:Label>
          </ContentTemplate>
          </asp:UpdatePanel>

和背后的代码

protected void Button1_Click(object sender, EventArgs e)
   {
       Label1.Text = "the value is:" + TextBox1.Text; //any code
   }
