如何访问wirzardstep旁边验证下拉列表？

问题描述

我试图找出如何评估wizardstep下一个按钮（或其他方式）以要求使用select作为第一个选项验证下拉列表。



我尝试过：

< asp：WizardStep runat =serverTitle =个人信息ID =step2> 
 
< asp：TextBox ID =txtsqlEmailrunat =serverVisible =False>< / asp：TextBox> 
< table border =1width =100％> 
< colgroup> 
< col style =width：60％> 
< col style =width：40％> 
< thead> 
< tr> 
< td style =text-align：right> 
员工ID：
< td> 
< asp：TextBox ID =txtEmpIdrunat =serverWidth =200pxAutoPostBack =TrueBackColor =＃3366FFEnabled =FalseForeColor =White>< / ASP：文本框> 
< / td> 
< / tr> 
< tr> 
< td style =text-align：right>标题：< / td> 
< td> 
<  - ！想要使用下一步按钮验证磁贴 - >

< / tr> 
< / thead> 
< / table> 
< / asp：WizardStep> 

解决方案

I am trying to find out how to assess a wizardstep next button (or another way) to require validate a dropdownlist with "select" as the first option.

What I have tried:

<asp:WizardStep runat="server" Title="Personal Information" ID="step2">
                
                <asp:TextBox ID="txtsqlEmail" runat="server" Visible="False"></asp:TextBox>
                <table border="1" width="100%">
                    <colgroup>
                        <col style="width: 60%">
                        <col style="width: 40%">
                    <thead>
                        <tr>
                            <td style="text-align: right">
                            Employee ID:
                        <td>
                            <asp:TextBox ID="txtEmpId" runat="server" Width="200px" AutoPostBack="True" BackColor="#3366FF" Enabled="False" ForeColor="White"></asp:TextBox>
                        </td>
                        </tr>
                        <tr>
                            <td style="text-align: right">Title:</td>
                            <td>
                                    <--!Want to require validate the tile using the next step button-->
                                <asp:DropDownList ID="DDTitle" runat="server" DataTextField="Title" DataSourceID="SqlTitle" AppendDataBoundItems="true"></asp:DropDownList>
                                <asp:RequiredFieldValidator ID="RequiredFieldValidator4" runat="server" ControlToValidate="DDTitle" ErrorMessage="Please select Title" Font-Size="Small"                                ForeColor="#FF3300"></asp:RequiredFieldValidator>
                            </td>
                        </tr>
                        <tr>
                            <td style="text-align: right">First Name:</td>
                            <td>
                                <asp:TextBox ID="txtFN" runat="server" Width="200px"></asp:TextBox></td>
                            <tr>
                                <td style="text-align: right">Last name:</td>
                                <td>
                                    <asp:TextBox ID="txtLN" runat="server" Width="200px"></asp:TextBox></td>
                            </tr>
                        <tr>
                            <td style="text-align: right">Email:</td>
                            <td>
                                <asp:TextBox ID="txtemail" runat="server" Width="200px" Enabled="False" BackColor="#3366FF" ForeColor="White"></asp:TextBox></td>
                        </tr>
                    </thead>
                </table>
            </asp:WizardStep>
