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，行为符合预期，客户端代码警告该字段是必需的。

但是当我指定ValidationGroup（如上例中所示）并且我单击文本框为空的按钮时，客户端代码什么都不做，按钮单击事件触发，Page.IsValid等于true，我的代码继续，与预期相反。

任何想法如何解决这个问题？

Answer 1

您在验证者上缺少验证组。

无需在控件（文本框）上指定验证组，而是在验证器上指定验证组，并在按钮上指定要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" />

Answer 2

在不在文本框中的验证器中尝试使用ValidationGroup =“NewDepartmentValidationGroup”

<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" />

ValidationGroup的RequiredFieldValidator不验证
