AssociatedControlId and UserControls

[MarkT]

I'm new to ASP.NET and have been asked to bring our site into 508 compliance. Right now I'm working on associating labels to form fields. This seems to work well with the built in controls provided but we are also using a lot of usercontrol in our application. I can set the AssociatedControlId of the label to the usercontrol but when you run the application and click on the label it dosen't set focus on the usercontrol.

Is there some trick to associating a label to a usercontrol?

I doubt this cannot be done

Because the Name suggest that

Label.AssociatedControlID Property

This only Can be associated with label ?

By usercontrol if you mean a web user control (*.ascx), then a web user control can be a combination of other controls, so associating a label with a user control does not make sense. Similarly, for server controls, unless it's a server control that renders one single HTML element, it doesn't make sense.

One of the tasks of 508 Compliance is to give labels a for attribute. Fair enough that you have the AssociatedControlID, but you need to understand that the AssociatedControlID will map to a server control which in turn becomes an HTML form field when it is rendered. Because a server control or user control doesn't necessarily become a form field, you need to know in advance what the ID of the form field is going to be (not the ASPX markup ID, but the rendered ID which looks something like ctl$00_blahblah_blah2).

I don't believe that the AssociatedControlID can be assigned to the rendered ID (ClientID), and so you will probably need to do something like this

Label1.Attributes.Add("for", TheOtherControl.ClientID)

Make sense. Thanks.

I will give Attributes.Add a try and see what happens.
