Updating updatepanel from javascript

30-Oct-2015 04:50

NET beta 2, with november CTP, running as a web application. can you post a small demo with the code you're trying to user? Now the problem is that if you have all your Update Panels set to Update Mode=Auto and some of the Update Panels aren't on the page. If it is being updated dynamically then it must be inside another Update Panel. Update Mode=Conditional makes it so that a given Update Panel is only updated when its Update() method is called or when the event originates inside itself.

I have quite a few Update Panels on my page and I didn't set the Update Mode property (which defaults to Auto). I hope I save some other developer some time figuring this out. I was struggling with a similar problem for the past couple of days, except I had a lot of dynamically created update panels on my control that was all conditionally updated. My problem was that I was trying to update() some of them while their parent control's visibillity was set to false. If you have an Update Panel in a container like Tab Panel or Panel, and you make this container invisible dynamically in runtime, then you have this error. After reading your post it came clear to me that the exception was originated when trying to update an update panel that was no longer on the page (as it;s parent control was invisible). I couldn't find any solution for this problem but may be you can find a work-around. Kulkarni Hey all, I have read through this thread and am still having some trouble. Net Code protected void Grid View1_Selected Index Changed(object sender, Event Args e) { Grid View1. It was what the error message says: I had an updatepanel surrounding the updatepanel I was updating. I just wrestled with this for the last two days and I need to make sure that nobody suffers with this again :). I had the same error when I put an Update Panel inside just a normal Panel and fixed the error by moving the updatepanel inside the panel instead. It works if the scriptmanager is on the masterpage or on the not-masterpage as long as I don't put my updatepanel inside anything else.

...there's a possibility that they were registered with the Script Manager but they aren't on the page (if for instance you play with the rendering of the page, which was my project's problem).

If that's the case it will look for the Update Panel in the DOM and it won't be able to find it and you'll get that message.

When there are no frameset and no asp: Content in the middle page, updatepanel runs perfect, however, using frameset and asp:content will cause the follow error in every page using updatepanel. Invalid Operation Exception: Could not find Updatepanel with ID '_ct10: Content Place Holder1: View Msgs'. If they're set to Auto then there's a possibility that they were registered with the Script Manager but they aren't on the page (if for instance you play with the rendering of the page, which was my project's problem).

There are no frames, but a masterpage, with a usercontrol that has an asp: Timer in it. I find the correct ID in the source code, however the error message seems to replace _ with :. a simple page will do just fine (if i can copy it here and run it)...i just want to be sure taht i've got it right before saying something. I'm afraid I have something wrong in my web.config then.... I also have problems with updatepanel triggers, so maybe my whole app is having a problem. I ended up setting most of my Update Panels to Update Mode=Conditional and this fixed it (since all of my updates are either explicit or self contained).
