Tutorial: Opening a Pop-up window in ASP.net

There are many reasons that a user would want to open up a new window from your ASP site. Maybe the clicked on a button or a link, maybe the current page just isn’t doing if for them.  Maybe their current page has self-esteem

issues, or weight issues.  Maybe their current page is getting a little thin on top, or doesn’t really do to well in the bedroom.

Back to maybe they clicked on a button.

Opening a new window from current page is actually quite simple! and can be accomplished in three steps:

  1. Create a control on the page that can handle and “onClick” event. This could be a plain HTML button, an anchor tag, an image, whatever…
  2. Double clicking on the control will open the code for the new HTML control. It should look like this:

function Button1_onclick() { }

Remember, for this to work you’ve got to use a plain HTML control, not a “runat=server” .net control. These are found in the HTML Tab on the left.

And finally, the code that goes inside is:

The parameters are (the url of the new window, the title of the new page, size stuff)

View the page, click on the button/link/whatever and Whala! a new window opens.
