RequiredFieldsValidatior asp.net c#

Question

我有一个包含两个 detailsView 的页面，我尝试为所有字段添加一个 RequiredFieldsValidator，它工作正常，但是当我添加 ValidationGroup 时，验证根本不起作用

问题是什么

第一个详细信息视图：

<asp:DetailsView ID="DetailsView1" runat="server" AutoGenerateRows="False"

Answer 1

尝试像这样使用..

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

您需要将验证组添加到您的 CommandField。例如：

<asp:CommandField ValidationGroup="1" ButtonType="Button" ShowInsertButton="True" />

我还建议您为验证组使用更有意义的名称

RequiredFieldsValidatior asp.net c#

RequiredFieldsValidatior asp.net c#

c#

asp.net

requiredfieldvalidator
