验证多个控件Asp.Net

Question

所以,我在一个页面上有一个登录框和一个注册框.两者都有RequiredField验证器.现在,当我点击登录或注册时,注册和登录的字段都会得到验证.

但是,我想要它,如果点击注册,只有注册字段得到验证,如果点击登录字段,则验证.

你能帮帮我吗？

非常感谢!

正如Dooie所说,你必须像这样分配VAlidation组

       <table width="100%"> 
       <tr> 
          <td> 
                <asp:TextBox ID="TextBox1" runat="server"></asp:TextBox> 
                <asp:RequiredFieldValidator 
   ID="RequiredFieldValidator1" runat="server" 
   ErrorMessage="RequiredFieldValidator" 
   ValidationGroup="Group1" ControlToValidate="TextBox1"> 
    </asp:RequiredFieldValidator> 
           </td>            
           </tr> 
        <tr> 
            <td> 
                <asp:TextBox ID="TextBox2" runat="server"></asp:TextBox> 
                <asp:RequiredFieldValidator 
     ID="RequiredFieldValidator2" runat="server" 
      ErrorMessage="RequiredFieldValidator" 
      ValidationGroup="Group2" ControlToValidate="TextBox2"> 
      </asp:RequiredFieldValidator> 
            </td> 
         </tr> 
        <tr> 
            <td> 
                   <asp:TextBox ID="TextBox3" runat="server"></asp:TextBox>  
     <asp:RequiredFieldValidator ID="RequiredFieldValidator3" runat="server"                                                
    ValidationGroup="Group3" ControlToValidate="TextBox3"> 
   </asp:RequiredFieldValidator> 
           </td> 
        </tr> 
        <tr> 
         <td> 
              <asp:TextBox ID="TextBox4" runat="server"></asp:TextBox> 
               <asp:RequiredFieldValidator 
                ID="RequiredFieldValidator4" runat="server"       ErrorMessage="RequiredFieldValidator" ControlToValidate="TextBox4">  
                  </asp:RequiredFieldValidator>             
           </td> 
       </tr> 
      <tr> 
           <td> 
                <asp:Button ID="btnSubmit" runat="server" Text="Submit" OnClientClick="javascript:return   validatePage();" /> 
               <asp:Button ID="btnCancel" runat="server" Text="Cancel" /> 
           </td> 
       </tr> 

对于所有验证,然后....从上面的标记中可以看出,有四个必需的字段验证器,在四个验证器中,三个验证组属性已定义.在这种情况下,当您单击提交按钮时,只会执行没有验证组的验证程序,即只执行RequiredFiedlValidator4.由于有多个验证组分配按钮'ValidationGroup不会工作,因为它只会执行属于指定的validaiton组的验证器控件.属于其他验证组的其他验证器控件将不会执行.此外,无法使用按钮控件的ValidationGroup属性指定多个validaiton组.

解决这个问题的方法是调用Page_ClientValidate javascript函数.Page_ClientValidate是ASP.NET生成的javascript函数.该函数将验证组名称作为参数.单击提交按钮时调用的javascript函数将粘贴在下面.

         <script language="javascript" type="text/javascript"> 
      function validatePage() 
      { 
  //Executes all the validation controls associated with group1 validaiton Group1. 
    var flag = Page_ClientValidate('Group1'); 
   if (flag) 
   //Executes all the validation controls associated with group1 validaiton Group2. 
        flag = Page_ClientValidate('Group2'); 
    if (flag) 
   //Executes all the validation controls associated with group1 validaiton Group3. 
       flag = Page_ClientValidate('Group3'); 
  if (flag) 
   //Executes all the validation controls which are not associated with any validation group. 
      flag = Page_ClientValidate(); 
    return flag; 
     } 
 </script>

希望这可以帮助................
