PermaLink JQuery UI Dialog and ASP.Net button postbacks11/11/2009 11:40 PM
When you use JQuery UI's Dialog plugin to bring up a div as a dialog, it usually pulls the div out of the form to do this and then ASP.Net elements don't work.  I found this clean solution to this from Ravi's Software+Usability Blog:
In your dialog creation code, add an open event handler:
    $('#divDialog').dialog({
      bgiframe: true, autoOpen: false, height: 175,
      width: 600, minWidth: 200, modal: true,
      open: function(type,data) {
        $(this).parent().appendTo("form");
      },
      close: function(type,data) {
        $(this).parent().replaceWith("");
      }
    });
This will bring the ASP.Net elements back inside the form so they can post back to the ASPX page properly.

Note: added the close event handler to get rid of the duplicate <div> thanks to Carl's comment below.

I ran into this issue while working on a Java web application, and found the latest version of jQuery lets you set "appendTo" during dialog initialization. This worked for me. Doing it this way avoided the need for the open or close functions described above. For example:

$( "#theDialogId" ).dialog({
autoOpen: false, width: 700, appendTo: "#theFormId", etc....

Hi Ken

Thanks for the help, but you forgot to wire a function to the Close event that removes the Div from the form. If you don’t do this then opening the Modal Dialog and closing it without submitting will create duplicates of your Div including the ASP.Net elements.

It took me a while to figure out why I was getting comma separated duplicate entries, so I would recommend updating your post to help as many as you can.

Check out my blog post to see how I did this. { Link }

Thank you sooooo much!

I have spent the morning messing around with nested updatepanels and never even considered that it may have been the JQ Dialog that was messing with me.

You've just earned a medal from me. Any idea what to with UpdatePanel inside Dialog? Or should I make it more simple and just Iframeit there...?

Thanks, this really helped me. I had a situation where multiple dialogs were on the page and because the inline function only runs when the dialog is opened, it does not conflict with the other dialogs. Thanks again.
