Html label tag and ASP.NET -

In the ASP.NET application & lt; Label & gt; What is the best way to use tags? I want it to be valid XHTML, accessible and usable.

I think the optimal way is:

  & lt; Label = "username" & gt; Username: & lt; / Labels & gt; & Lt; Input type = "text" id = "user name" runat = "server" />  

But if the above code is in an ASP.NET user control, the input id will change, which means the "for" attribute for labels is useless. I can control the label tag one server and it can set the "to-do" attribute for the code (username id. Client id) but it seems that there is a lot of work for such a simple thing.

I have also seen this HTML used in the past:

   & Lt; / Labels & gt;  

What is the optimal approach?

I & lt; Asp: label ... associate control id = "user name" ... & gt; Control for this & lt; Label & gt; is sung in the form of tags and set the attribute to fit appropriately.

Note that you can also nest other tags within the label control you want:

  & lt; Asp: Label ID = "UsernameLabel" Text = "Username:" AssociatedControlID = "UsernameTextBox" runat = "server" & gt; & Lt; ASP: Textbox ID = "UsernameNext Box" Runat = "Server" /> & Lt; / ASP: Labels & gt;
