As a result, my dialog's HTML needs to be dynamically generated at runtime. My usual case is that the contents of the dialog box are driven by data that the user has currently entered on the page.

.Do something to update the page from the dialog. Here's a skeleton for the standard functions: I typically have my OK button finish by calling the Cancel button's function. I follow my button definitions with their functions. A typical dialog has two buttons: an OK button (which will call a function that does something) and a Cancel button (which will call a function that just closes the dialog), so my usual button definitions look like this:

To work with the jQueryUI dialog, these literals must have a name property (the text that the button will display) and a click property (the function to execute when the user clicks the button). Inside that DisplayUpdateCustomerDialog function, my first step is to use a set of JavaScript object literals to define the buttons I want to add to the dialog.

Because I usually retrieve the HTML from the server, my div element starts out with nothing in it:įinally, I need some JavaScript code to wire up my showDialog button to a function that will, eventually, display the dialog (I've called that function DisplayUpdateCustomerDialog): The dialog displays HTML stored somewhere on the page so I use a non-displayable div element to hold that HTML. The page also needs a submit button, of course: You'll also need the jQueryUI CSS file to set the appearance of your dialog:įor my case study, I'm assuming a form that displays a customer id and name along with a button that allows the user to update the customer information through a dialog (I assume that the bulk of the page is handling some other information). I've assumed an ASP.NET MVC project for my sample code but, if you're working in an ASP.NET WebForms project, you can use the ASP.NET Web API.Ī View that uses the plug-in needs script tags for both the jQuery and jQueryUI libraries. For most scenarios where you'll use the dialog plug-in, you'll also need a Web service to deliver the HTML your dialog will display. To use the jQueryUI dialog plug-in you'll need to add the jQuery and the jQueryUI libraries to your project.

Finally, with a dialog your communication with the server involves less overhead than first displaying a completely new page and then re-displaying the original page: your application is more scalable and the user gets a more responsive UX.

Second, because you never leave the original page, you avoid any navigation problems related to going away and returning to the original page. First, with a dialog, the original page is still in the browser so your code behind your dialog still has access to the page's data (and, for the same reason, you can easily update the page with data from the dialog). That's good because there are lots of benefits to just popping open a dialog. Fortunately, the jQueryUI dialog plug-in makes it easy to duplicate the desktop dialog box in a Web page (and pop-up blockers don't interfere with it). In a Web application, on the other hand, the default solution is to send the user to another page, then return them to the original page when the task is completed. One of the things desktop developers take for granted is the ability to open a dialog box to gather more data from the user or to allow the user to perform a related task.
