Can anyone tell me the easiest way to display a jQuery dialogafter a postback occurs.
Basically i am showing some asp.net controls inside my jQuery dialog and when i click something an event occurs in asp.net
But of course after the postback has finished the screen is brought back up but WITHOUT the jQuery dialog.. This is by design I presume but wondered if there was a way around this?
I am using the updatepanel (asp.net).
Any ideas really appreciated?
Thanks
You could use the ScriptManager.RegisterStartupScript to load the popup. See documentation

I have an asp.net page with a timer embedded in an UpdatePanel (UpdateMode="Conditional", ChildrenAsTriggers="false"). The timer is responsible for updating some components of that page every few seconds.
There are also some HyperLink controls on the page and they open a JQueryMobile dialog when clicked (data-rel="dialog"). The problem is that the timer i mentioned causes postback every few seconds. So when a dialog is opened and then closed, the first such postback after then causes the dialog to open once again.
Using the rel="external" as another attribute of the HyperLinks I mentioned solves the problem, but this is no solution for me. This causes full redirection to the dialog page instead of showing it using AJAX (as if on top of current page).
My idea was to stop the timer when any hyperlink is clicked. This solves the problem, but I have no idea how to start the timer again when the dialog closes. Is it possible to detect when a JQueryMobile dialog is closed? I know, this sounds stupid, but I can't come up with a better idea. Will you help me, please?
So basically, I don't want the JQueryMobile dialog page to show up for the second time after a timer tick. Could you please advise me how to achieve that?
jQuery Mobile with asp.net Web Forms and an UpdatePannel? This just sounds like a horrible combination.
jQuery Mobile and Web Forms fundamentally don't work well together. The specific issue that Web Forms requires a single <form /> element that wraps all controls (and most content). jQuery Mobile attempts to build up the DOM with "virtual" pages via ajax loading. This breaks the PostBack model by submitting the entire form instead of the individual form found within each page template. Now throw UpdatePanels in there...
Your only hope is go exclusively with Single page templates and to disable all ajax loading data-ajax="false" on both links and forms. And just say no to UpdatePanels.
asp.net MVC would give you much greater control over these issues.
I'm building an web application using Asp.Net, How I can load other page or control ( like login or feedback form) in dialog and make sure postback events of that control/page execute successfully.
Take a look at jQuery WoWWindow.
After trying out various JQuery plugins, I finally choose popup extender of Asp.Net Ajax control toolkit.
The problem that I was facing with JQuery plugins, they do not handle postpack event properly. JQuery UI dialog is the closest match to my requirement, I will try it again next time.
I have a dundas chart with ajax zooming and scrolling enable.
It works fine in a webform page. But once I put in a user control and called it from another page I get this error -
the target 'ctl00$ContentPlaceHolder1$uc2$chartVisits' for the callback could not be found or did not implement ICallbackEventHandler.
-when I try to use the zoom and scroll functionality.
What can I do to resolve this problem.
Thank You.
I've seen this error when dynamically adding controls that use AJAX. Make sure you're adding any controls in the OnInit method, or during the Page_Init event. That has solved this problem for me in the past.
I have a problem with expanding/collapsing a Treeview control in an Updatepanel which causes weird behavior and functions fine if placed outside the Updatepanel.
I have found that TreeViews is not supported in updatePanels so my question is:
What is a workaround to avoid a full postback whilst keeping expand/collapse functionality as well as TreeNode_clicks that updates another control?
Also why does it seem that some people use a TreeView inside an Updatepanel with success? Is this only an ASP2 prolbem?
It's the loading of the treeview javascript that fails under an updatepanel. I've tried putting some explanations and options below in bullet points.
The control will work in an updatepanel if it is visible straight away.
The control will not work in an updatepanel if it is made visible after a postback.
If you disable the client side javascript, the control will work in an updatepanel but will cause a postback every time a plus/minus is clicked.
Hope that helps
TreeView in .Net 2.0 doesn't need to postback on expand/collapse.
Have you tried to put an UpdatePanel around the control you wish to update with a trigger
< asp:PostBackTrigger ControlID="treeView" />
As declared by Microsoft, treeview is not compatible with UpdatePanel. So you are having all the issues. I have managed the same to a quite acceptable level in one of my project. You can refer to the posts on the same as follows: http://www.geekays.net/post/Using-TreeView-inside-AJAX-UpdatePanel.aspx and http://www.geekays.net/post/TreeView-control-postbacks-on-check-and-uncheck-of-the-nodes-Checkbox.aspx
Let me know if it helps.
I am trying to get a crosspage postback to work in asp.net 2.0 the issue I seem to be having is the button that I press is meant to use it's on click event to store some session variables based on the values of other controls. This button has crosspage postback property to the relevant page.
The on click event seems to not run at all, it just seems to perform the postback to the other page straight away.
Is this standard behavior? Any work around?
I think I have found my answer

Seems like the transfer will be instant, no onClick event will run. The alternative is to use Server.Transfer in the onClick event.
Any other comments appreciated.
