带有ValidationGroup的RequiredFieldValidator不验证

Question

这是我的标记：

Name: 
<asp:TextBox ID="txtNewName" runat="server" ValidationGroup="NewDepartmentValidationGroup" />
<asp:RequiredFieldValidator ID="vldtxtNewName" runat="server" ControlToValidate="txtNewName"
    ErrorMessage="Required Field" /><br />
Description: 
<asp:TextBox ID="txtNewDescription" runat="server"          
    ValidationGroup="NewDepartmentValidationGroup"/>
<asp:RequiredFieldValidator ID="vldtxtNewDescription" runat="server" 
    ControlToValidate="txtNewDescription" ErrorMessage="Required Field" /><br />
<asp:Button ID="cmdCreate" runat="server" Text="Create"
     ValidationGroup="NewDepartmentValidationGroup" OnClick="cmdCreate_Click" />

当我删除ValidationGroup属性时，行为与预期一致，客户端代码警告该字段为必填字段。

但是，当我指定ValidationGroup (如上面的示例所述)并在文本框为空的情况下单击按钮时，客户端代码什么也不做，按钮单击事件激发，Page.IsValid等于true，我的代码继续执行，这与预期相反。

有什么办法解决这个问题吗？

Answer 1

验证器上缺少验证组。

不需要在控件(文本框)上指定验证组，而是在验证器上指定验证组，并指定要在其上发布有效数据的按钮！

试试这个：

    Name: 
<asp:TextBox ID="txtNewName" runat="server" />
<asp:RequiredFieldValidator ID="vldtxtNewName" runat="server"
     ControlToValidate="txtNewName" ValidationGroup="NewDepartmentValidationGroup" 
     ErrorMessage="Required Field" /><br />
Description: 
<asp:TextBox ID="txtNewDescription" runat="server" />
<asp:RequiredFieldValidator ID="vldtxtNewDescription" runat="server" 
    ControlToValidate="txtNewDescription" ErrorMessage="Required Field"
    ValidationGroup="NewDepartmentValidationGroup" /><br />
<asp:Button ID="cmdCreate" runat="server" Text="Create"
     ValidationGroup="NewDepartmentValidationGroup" OnClick="cmdCreate_Click" />

尝试在验证器中使用ValidationGroup="NewDepartmentValidationGroup“，而不是在文本框中

<asp:TextBox ID="txtNewName" runat="server"  />
        <asp:RequiredFieldValidator ID="vldtxtNewName" runat="server" ControlToValidate="txtNewName"  ValidationGroup="NewDepartmentValidationGroup"
            ErrorMessage="Required Field" /><br />
Description: 
<asp:TextBox ID="txtNewDescription" runat="server"          
    />

<asp:RequiredFieldValidator ID="vldtxtNewDescription" runat="server" 
    ControlToValidate="txtNewDescription" ErrorMessage="Required Field" ValidationGroup="NewDepartmentValidationGroup"/><br />

<asp:Button ID="cmdCreate" runat="server" Text="Create"
      ValidationGroup="NewDepartmentValidationGroup" OnClick="cmdCreate_Click" causesvalidation="true" />
