AJAX :: How To Update Multiple Updatepanels Simultaneously
Feb 3, 2010
I have a page in which there are multiple updatepanels and each of these update panels are trigerred by different triggers.
These update panels are used to do Async post back and the page is updated with the data retrieved from the async post back.
Now the issue i am facing is that since there are multiple update panels, the update done by one panel is lost when the other panels does the post back.
let me know if any one knows on how to solve this issue.

On my page which uses nested master pages, I have several user controls which are in their own UpdatePanels.
I've noticed that when I update something which is in UpdatePanel 2, things are shifting slightly in UpdatePanel 1. Someone told me that when UpdatePanels are used, the page is reloading anyway. Is this true?
How do I prevent UpdatePanel 2 affecting UpdatePanel 1?
P.S. All update panels are set to Conditional in their UpdateMode's.

I just want to make sure that I got this right. If I have two update panels, and updatepanel1 has 10 dynamic controls created from an external button that resides on the page by default.. and then i have a second button which also is on the page by default but is an asynctrigger to updatepanel2...
then when the first updatepanel1 is populated with dynamic controls, then when I click button2 to update the second updatepanel2 with some data, the dynamic controls in updatepanel1 wil;l still remain there right? but does it persist by itself on postback? And if so why?
because when I click button2 to update updatepanel2, it does a partial page postback. So when it does a partial page postback, does that mean it does not destroy updatepanel1's dynamic controls?

I seem to be having issues trying to programmatically update one of the UpdatePanels on a page i'm developing.Basically what i'm trying to do is...
have one update panel on the master page (used to show summary info like errors and success message) and then a updatepanel on the content pages, all of which are conditional. where its not working (or i'm doing something wrong) is when i call a method in the master page to update its updatepanel to show the new summary message it does nothing.
i.e. (content page)
page_load()...
{
try
{
load content. [code]....

I have been reading a lot about UpdateMode set to Conditional on multiple UpdatePanels on a page. It seems that when set to Conditional only the UpdatePanel affected by the event will refresh. It is not happening on my case and I don't know what am I doing wrong.
This is the scenario. I have 4 updatePanel all set to Conditional. I have external buttons that will call the Update method per each panel but the whole page refreshes when I click on any of the buttons.
Here is a sample code:

In my asp.net application in one of the Page I need to create 3 Panels. These 3 Panels I had already kept in 3 Updatepanels. Now, Outside the UpdatePanels, I have a dropdown. Selecting the Value from Dropdown, those 3 panels will be populated from database.
Each of the UpdatePanels have their UpdateProgrees Control. Now What I want is that those 3 UpdatePanels should filled up one by one.
How to achieve this functionality ?

Was wondering if someone can help me out with this multi update problem
I have a webform that populates a single table but due to certain dropdown data conditions it could also potentially populate 3 other tables
The tables information populates a gridview with amounts from accounts etc..
e.g.
Table 1
Site DataType account update
34 SS 12.50 N
Table 2
Site account
34 12.50
Say the above entry has the updated column changed to Y via the webform the amount 12.50 should disappear from the gridview. I was
a bit shortsighted and added the additional tables afterward. The information on the gridview pulls from the additional tables and since
the first table and the additional tables are not linked the data still stays the same in the gridview
I do have an Id column on both tables but unfortunately I added the rest of the tables after the first one so the Id's do not really match.

In general, If multiple users thru an application try to update the same tables in database simultaneously, then by default on what basis the priority will be given.Like if we don't have any extra logic for the locking implemented.

Can someone provide a good example of multiple UpdatePanels being updated by a singe Dynamic Populate extender? Is there some way to have one UpdatePanel trigger another to make a call and subsequently update another UpdatePanel?

I have a user control, that has an update panel and update progress control in it.
I use this user control in more than 1 location on the same page.... problem is, when ucA posts back, I see the update progress control for both ucA and ucB. I assume this is because it is a user control and the update panel and progress are named the same?
Either way - how do I make it so that the update progress only displays for the proper user control?

I have an update panel in my ASP.NET web form with a trigger that will fire a click event when the contents within my update panel is updated (it's a grid view with fields). The event that is fired when then take the changes user made and do some calculation and then update another update panel with that information. This is all fine and dandy when the user tabs along the form and fill out the form in a orderly fashion before hitting any buttons on the page.
If a user accidentally hits another button on the page while changing the content in my grid within the update panel, for example, the user enter a value in my grid view control, without tabbing, the user click the save button. Logically, i believe that the trigger should fire the click event first (event A), and then the save button event (event B). But, consistently I haven't seen event A gets fire correctly while event B gets fire all the time. is there a way to ensure event A always gets fired before event B? also if event A update another update panel without the page will event B fire after the update is complete?

I moved from the FileUpload control to the AsyncFileUpload control.
1) Do AsyncFileUpload controls work under UpdatePanels??? (Please provide example or reference)
2) Can AsyncFileUpload controls be triggerd with an update button (both inside the same updatepanel)?

I have a problem on my website, when using updatepanels:
Most of the time everything works fine, but a few times a day a user will get an error 500 as response to a partial postback in an updatepanel. The problems are:
1) I can see in my server logs that the request is processed without errors.
2) There is no log entry from the function handling AsyncPostBackErrors, although that is the first thing it does.
3) The function handling AsyncPostBackErrors changes the AsyncPostBackErrorMessage, but the users see a generic text which the function will never output.
So my theory is that the request does not cause an syncPostBackError at all. I can see in the logs, that there have always been an AsyncPostBackError from another request at almost the same time. So I suspect that one request somehow gets tainted with the error of the failing request.

I am fairly new to ASP.NET and just started using UpdatePanels.Here's what I'm trying to accomplish. I have a button which is wrapped up in the UpdatePanel like so:
[Code]....
The following is the mark-up for the textbox which is supposed trigger an update when its text changes:
[Code]....
With the current set-up, the button's text doesn't change when the textbox content changes. At first I suspected that the reason it didn't modify button's text was because I didn't set AutoPostBack to true on the textbox (tried enabling and it didn't work though),
but then I why would I want to? I'm not getting any data from the server - I just want to update a button on the client side.
I'd really appreciate if you could point out what I'm doing wrong and maybe also clarify when AutoPostBack is absolutely necessary and what are some of the special cases in which it needs to be used.
