Default Enter Button - June 2011

If you download this tip please consider making a modest donation.

One of my clients repeatedly used 'Enter' to login after entering their user name and password rather than using the mouse to click a 'Login' button. I wondered if there was a way to force the login event to fire when the Enter key was pressed. I searched the web and found several suggestions. A web form or Asp.Net panel accepts attribute 'defaultbutton'. I did some testing - it works. So it becomes the June 2011 Tip-of-the-Month.

I published the application on the web. Click here to run the demo application.

The Demo Application

The Asp.Net, VB.Net, VS/2008 project DefaultButton consists of two forms. The forms:


Press 'Enter' to fire the Login button event which redirects to the next page.
In this example the attribute is part of the form definition in the aspx page.


The user name and password are passed in a query string.
Press 'Enter' to return to the first page.
In this example the attribute is added in the CodeBehind page.

DefaultButton Attribute

A web 'runat=server' Form or Asp.Net Panel accepts attribute defaultbutton. This demo uses the Form attribute with both pages. I use the panel attribute in my production application.
