“更新”面板中的必填字段验证程序 [英] Required field validator with Update panel

问题描述

大家好，

我被困在一个代码中。请帮帮我。在此先感谢。



我试图从我们的数据库检查用户名可用性。我有一个页面有控件：电子邮件ID的文本框，密码的文本框和必填字段验证器与密码框相关联。



问题是当我点击按钮检查可用性时，所需的字段验证器被触发，我无法执行所需的工作。以下是代码：

< asp：scriptmanager id =ScriptManager1runat =serverenablepartialrendering =truexmlns：asp =＃unknown> ; 
< / asp：scriptmanager> 
< asp：updatepanel id =UpdatePanel1runat =serverxmlns：asp =＃unknown> 
< contenttemplate> 
< table align =centerclass =style1> 
< tr> 
< td align =leftclass =style5> 
电子邮件ID *< / td> 
< td align =leftclass =style4> 
< asp：textbox id =txtuidrunat =server>< / asp：textbox> 
< / td> 
< td class =style8> 
< asp：requiredfieldvalidator id =RequiredFieldValidator1runat =server> 
 ControlToValidate =txtuidErrorMessage =登录ID必须

< td>

< asp：linkbutton id =lbtavlblerunat =serveronclick =lbtavlble_Click>检查

< table align =centerclass =style1>

< asp：requiredfieldvalidator id =RequiredFieldValidator2runat =serverxmlns：asp =＃unknown>

字体粗体=真字体 - 斜体=假& gt;< / asp：requiredfieldvalidator> 
< / td> 
< td> 
& nbsp;< / td> 
< / tr>< / table> 

解决方案

你可以通过将ValidationGroup添加到您的LinkBut​​ton并将另一个带有ValidationGroup的RequiredFieldValidator添加到您的Eamil Id TextBox来解决这个问题

我的意思是说...添加一个必填字段如下



< asp：requiredfieldvalidator id =RequiredFieldValidator3runat =serverxmlns：asp =＃unknown>

ControlToValidate =txtuidErrorMessage = 登录ID必须Font-Bold =TrueValidationGroup =avbl>





并将链接按钮更新为



< asp：linkbutton id =lbtavlblerunat =serveronclick =lbtavlble_Clickvalidationgroup =avblxmlns：asp =＃unknown> ;检查可用性

我有一个不同的场景，这对我不起作用。但我确实找到了解决方案，你可以在我的博客上阅读：

Hello everyone,
I am stuck in a code. Please help me out. Thanks in advance.

I m trying to check the username availability from our database. I have a page having controls: a text box for email-id,text box for password and a required field validater is associated with the password box.

The problem is that when ever i click the button to check the availability, the required field validater is fired and i can not perform the desire work. Here is the code of it:

<asp:scriptmanager id="ScriptManager1" runat="server" enablepartialrendering="true" xmlns:asp="#unknown">
        </asp:scriptmanager>
        <asp:updatepanel id="UpdatePanel1" runat="server" xmlns:asp="#unknown">
            <contenttemplate>
                <table align="center" class="style1">
                    <tr>
                        <td align="left" class="style5">
                            Email ID *</td>
                        <td align="left" class="style4">
                            <asp:textbox id="txtuid" runat="server"></asp:textbox>
                        </td>
                        <td class="style8">
                            <asp:requiredfieldvalidator id="RequiredFieldValidator1" runat="server">
                    ControlToValidate="txtuid" ErrorMessage="Login ID is must" 
                    Font-Bold="True"&gt;</asp:requiredfieldvalidator>
                        </td>
                        <td>
                            &nbsp;</td>
                    </tr>
                    <tr>
                        <td align="left" class="style5">
                            <asp:linkbutton id="lbtavlble" runat="server" onclick="lbtavlble_Click">Check 
                Availablity</asp:linkbutton>
                        </td>
                        <td align="left" class="style4">
                            <asp:label id="lblerror" runat="server" forecolor="Red"></asp:label>
                        </td>
                        <td class="style8">
                            &nbsp;</td>
                        <td>
                            &nbsp;</td>
                    </tr>
                </table>
            </contenttemplate>
        </asp:updatepanel>
    <table align="center" class="style1">
        <tr>
            <td align="left" class="style5">
                Password</td>
            <td align="left" class="style4">
                <asp:textbox id="txtpasword" runat="server" textmode="Password" xmlns:asp="#unknown"></asp:textbox>
            </td>
            <td class="style8">
                <asp:requiredfieldvalidator id="RequiredFieldValidator2" runat="server" xmlns:asp="#unknown">
                    ControlToValidate="txtpasword" ErrorMessage="Pls Type ur Password" 
                    Font-Bold="True" Font-Italic="False"&gt;</asp:requiredfieldvalidator>
                   </td>
            <td>
                &nbsp;</td>
        </tr></table>

解决方案

Hi,
you can solve this by adding ValidationGroup to your LinkButton and adding another RequiredFieldValidator with that ValidationGroup to your Eamil Id TextBox

I mean to say .. to add a required field as follows

<asp:requiredfieldvalidator id="RequiredFieldValidator3" runat="server" xmlns:asp="#unknown">
ControlToValidate="txtuid" ErrorMessage="Login ID is must" Font-Bold="True" ValidationGroup="avbl">


and update your link button as

<asp:linkbutton id="lbtavlble" runat="server" onclick="lbtavlble_Click" validationgroup="avbl" xmlns:asp="#unknown">Check Availablity

I had a bit of a different scenario and this didn't work for me. I did however find a solution, you can read it on my blog:
