我有这个标记代码： 

<div id="rowIndirizzo" class="form">
    <label>
        Indirizzo:</label>
    <asp:DropDownList ID="ddlToponimo" CssClass="indirizzo" runat="server" DataTextField="Toponimo"
        DataValueField="Toponimo">
    </asp:DropDownList>
    <asp:TextBox ID="txtStrada" CssClass="textinputStrada" runat="server"></asp:TextBox>
    <asp:TextBox ID="txtNumCivico" CssClass="textinputCivico" runat="server"></asp:TextBox>
</div>
<div id="divCap" class="form">
    <label>
        CAP:</label>
    <asp:TextBox ID="txtCAP" CssClass="textinputCAP" runat="server"></asp:TextBox>
</div>
<asp:RequiredFieldValidator ID="rfvToponimo" CssClass="errore2" runat="server" ControlToValidate="ddlToponimo"
    ErrorMessage="Il campo toponimo dell'indirizzo è obbligatorio." Display="Dynamic"
    ValidationGroup="Step4_StruttPrivata1Step" Style="color: Red; display: block !important;"></asp:RequiredFieldValidator>
<asp:RequiredFieldValidator ID="rfvStrada" CssClass="errore2" runat="server" ControlToValidate="txtStrada"
    ErrorMessage="Il campo strada dell'indirizzo è obbligatorio." Display="Dynamic"
    ValidationGroup="Step4_StruttPrivata1Step" Style="color: Red; display: block !important;"></asp:RequiredFieldValidator>
<asp:RequiredFieldValidator ID="rfvNumCivico" CssClass="errore2" runat="server" ControlToValidate="txtNumCivico"
    ErrorMessage="Il campo numero civico dell'indirizzo è obbligatorio." Display="Dynamic"
    ValidationGroup="Step4_StruttPrivata1Step" Style="color: Red; display: block !important;"></asp:RequiredFieldValidator>
<asp:RequiredFieldValidator ID="rfvCAP" CssClass="errore2" runat="server" ControlToValidate="txtCAP"
    ErrorMessage="Il campo CAP è obbligatorio." Display="Dynamic" 
    ValidationGroup="Step4_StruttPrivata1Step" Style="color: Red;
    display: block !important;"></asp:RequiredFieldValidator>
<asp:RegularExpressionValidator ID="revCAP" runat="server" ControlToValidate="txtCAP"
    ValidationExpression="^([0-9]{5})$" ErrorMessage="Il formato del CAP è errato (Es. 01234)"
    Display="Dynamic" ValidationGroup="Step4_StruttPrivata1Step" Style="color: Red;
    display: block !important;" />
<asp:Button ID="btnSearchIndirizzo" OnClientClick="return false;" class="buttonnext" runat="server" Text="Inserisci"
    ValidationGroup="Step4_StruttPrivata1Step"></asp:Button>

我有一些控件可以验证按钮单击，但我不想要回发（我不能使用输入按钮，因为不触发 rfv）。我已经尝试过 onclientclick 事件......但没有。

更新：我已修改 dummyFunction 代码以显式触发客户端验证并在页面无效时停止回发。

在您的按钮标记上尝试以下属性

UseSubmitBehavior = false

您可能还想尝试

OnClientClick = "return dummyFunction();"

然后有一个JS函数dummyFunction如

 function dummyFunction(){

//this command will explicitly fire the validation
    Page_ClientValidate();
    return Page_IsValid; //Page_IsValid is set to true or false depending on whether a page is valid or not after client validation
    }

您可以在进一步进入 onClientClick 之前使页面进行验证我的意思是您可以从 OnClientClick 触发它，它将执行必填字段验证器。

只需将其添加到您的客户端点击功能中：

函数 myOnClientClick()

{

if (Page_ClientValidate()) // 这将触发验证器

{

//然后做客户端的事情

}

}
