Question

所以，假设我有一个用户控件，在aspx文件中调用了7次，我将字段验证器控件放在该用户控件中，问题是每次我点击一些导致回发的按钮，字段验证器总是验证对所有实例的控件我的用户控件，我想要的是验证特定的用户控件，我试过这个：

<asp:TextBox runat="server" ID="DateNew" CssClass="time" Width="185px"/>
<asp:RequiredFieldValidator ID="RequiredFieldValidator1" runat="server" ErrorMessage="Date can not be empty" ControlToValidate="DateNew" ValidationGroup='<%= ClientID %>' Text="*"> </asp:RequiredFieldValidator> 
 <asp:Button runat="server" ID="NewSchedule" Text="Schedule" CssClass="bgrey" 
        OnClientClick="CheckKeyValues()" OnClick="NewSchedule_Click"  ValidationGroup='<%= ClientId %>'/>

这不起作用......任何更正？比以前。顺便说一下这个例子会很棒。

更新：带有7次用户控件的aspx文件

 <asp:ScriptManager id="ScriptManager1" runat="server">
                        </asp:ScriptManager>
                        <div id="divError" class="n fail" style="display:none; margin:15px; width:2330px">

                             </h5>
                             <asp:ValidationSummary ID="ValidationSummary" runat="server" />

C＃：

 public String ValidationGroup
        {
            get 
            { 
                return RequiredFieldValidator1.ValidationGroup;
            }
            set
            {
                RequiredFieldValidator1.ValidationGroup = value;
                RequiredFieldValidator2.ValidationGroup = value;
                RequiredFieldValidator3.ValidationGroup = value;
                RequiredFieldValidator4.ValidationGroup = value;
                RequiredFieldValidator5.ValidationGroup = value;
                NewSchedule.ValidationGroup = value;
            }
        }


  protected void Page_Load(object sender, EventArgs e)
        {

                ValidationGroup = this.ID;
        }

Answer 1

在名为ValidationGroup的Web用户控件上公开属性：

public String ValidationGroup
{
    get { return RequiredFieldValidator1.ValidationGroup; }
    set { 
        RequiredFieldValidator1.ValidationGroup = value; 
        NewSchedule.ValidationGroup = value; 
    }
}

然后将其设置为您在Web表单上创建的每个实例的唯一值。

Answer 2

将验证组的值赋予我所提供的“名称”之类的值。并将相同的验证组添加到要触发验证的控件和其后退应该冷却验证的控件。

     <asp:TextBox ID="TextBox1" runat="server" ValidationGroup="Name"></asp:TextBox>
    <asp:RequiredFieldValidator ID="RequiredFieldValidator1" runat="server" 
        ErrorMessage="Field value is required" ControlToValidate="TextBox1" 
        ValidationGroup="Name"></asp:RequiredFieldValidator>
    <asp:Button ID="Button1" runat="server" Text="Button" ValidationGroup="Name" />
    <asp:Button ID="Button2" runat="server" Text="Button" />

在这种情况下，TextBox1验证仅在单击Button1而不是Button2单击事件时触发。

如何设置RequiredFieldValidator以针对具有多个实例的特定用户控件进行验证？
