输入类型=“电子邮件”设置值在asp.net代码后面

Question

How can I assign value to

<input type="email" class="form-control" placeholder="User name" required="" autofocus="" name="txtEmailId" id="txtEmailId" /> 

in the code behind?

Answer 1

Use runat="server" with markup

<input type="email" runat="server" class="form-control" placeholder="User name" required="" autofocus="" name="txtEmailId" id="txtEmailId" /> 

Now on code behind you can access it via txtEmailId

As Html 5 control is not available using runat attribute. You can directly use the TextBox like this

<asp:TextBox ID="txtEmailId" runat="server" TextMode="Email"></asp:TextBox>
