After applying the AJAX Dialog Box Wizard according to the instructions described here, the dialog box in browser should look as it follows:
As you can see in the image above, there are a few elements that characterize a dialog box built with MX AJAX Toolbox:
When the text link in page is clicked, the dialog box opens in the center and the page background becomes grey, making the dialog the main focus.
The width and the height of the dialog box are the ones set when configuring the AJAX Dialog Box Wizard.
The title bar is displayed at the top of the dialog box. The content is retrieved from a file.
Check out the MX AJAX Toolbox demo site and click the MX AJAX Toolbox item in the menu on the left. In that tabset, click the Features tab. The last link in the content there will open an AJAX dialog box. Try it out!
