Is it possible to prevent an asp.net Hyperlink control from linking, i.e. so that it appears as a label, without actually having to replace the control with a label?

The .Net generated code for a form with the "DefaultButton" attribute set contains poor javascript that allows the functionality to work in IE but not in other browsers (Firefox specifcially).

I'm planning to develop an ASP.NET server control to provide asynchronous username availability validation for new user registrations. The control will allow a developer to point it at a "username" TextBox and it will provide an indication of whether or not the username is available.

I have a few controls that inherit from ASP.NET buttons and use 'onserverclick'. If the user clicks twice, the button fires two server side events. How can I prevent this? I tried setting "this.disabled='true'" after the click (in the 'onclick' attribute) via javascript, but that blocks the first postback as well. ...

I am implementing a HttpRequestValidationException in my Application_Error Handler, and if possible, I want to display a custom message. Now, I'm thinking about the StatusCode. In my current example, it sends a 200, which I think should not be done. I would like to send the (IMHO) more appropriate 400 Bad Request instead. However, at th...

Its true the hardware load balancer could be set to sticky sessions to solve the issue, but in a perfect world, I would like the feature turned off.

I have a scenario wherein, for example, I need to repeat a list of US states and display a table of cities and city populations after the name of each state.
