AJAX :: Multiple UpdatePanels Should Execute One By One, But Button Is Outside Those Updatepanel
Jul 14, 2010
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 ?

I am having now two UpdatePanels on the same content page. One is a big UpdatePanel and another is a very small one. I can insert the little one content to the big one, but it means some info I don't need to update with Ajax at all will be init two, because of UI issues. What is better for performance? One big UpdatePanel or a small ones?

I hope this is a really easy question but I'm struggling with it. I have a GridView that has an UpdatePanel within a TemplateField.
The idea is that the user can make simple alterations without a full page load being required.
I have simulated my page functionality in the following example, which simulates a database hit, gridview databinding and updatepanel functionality.
When you press any of the + or - buttons in the GridView, the form controls in the bottom UpdatePanel also post their contents back. I have seen this by using Firebug. On my real page however this is causing excessive bandwidth and is nearly the same as a full postback.
how I can force ONLY the appropriate UpdatePanel's contents to postback for processing, rather than all the UpdatePanels?? I've tried experimenting with Triggers but just can't get it working properly.

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 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:

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.

I'm trying to understand how to execute AJAX animation on an asp button that has to execute code on Postback. In other words, I have button with code behind that needs to be excuted, but at the same time want to be able to have one of animation extenders be applied to it. I understand that I need to use the BeginRequest Event, I'm just not sure how, or which javascript commands to use to call the ajax animation so the postback will still occur.

I'm not sure if this is an easy issue to solve, but I can't seem to figure it out. I have a ModalPopupExtender (obviously) for a panel that contains a two labels, two textboxes, and two buttons (Ok and Cancel). What I would like to do is when the Ok button is clicked, the page post back and the server click event execute (along with normal page events). When I try adding "__doPostBack("ModalOk", "");" as the OnOkScript, the page posts back, but the click event doesn't execute. (the click event is Protected Sub ModalOk_Click(blah blah) Handles ModalOk.Click).
The only way I got it to work (which is fine with me, I just thought I'd ask why it isn't working normally) is by checking to see if the Request.Form("__EVENTTARGET") is equal to "ModalOk". If it is, then I call the ModalOk_Click() sub. Like I said, this is fine with me, but it should be able to be avoided. If the __EVENTTARGET is equal to "ModalOk", then the "Handles ModalOk.Click" event should automatically be called, shouldn't it? Following with the general problem here, how does the server determine which events (other than the page events) to execute (or at least which button.click event)? I understand that the __EVENTTARGET supplies what causes the postback, but if a button is clicked then __EVENTTARGET is not set. So then does the page check the Request.Form for a button? Or is it more complex/simple than what I'm asking?

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 want to trigger two Async Postbacks at once using UpdatePanel's via their associated buttons such as the example at the end of [URL] When you click the first button, then immediately click the second button, the first button's message never gets updated. By clicking the second button, the first async Post back seems to be cancelled. Why does this happen?
I saw this article about only allowing one postback to occur at a time here: [URL] Is this the desired behavior for Multiple update panels? Can only one run async code at once? What's the point of it being async if you can't do multiple at once? Here's what I'm trying to do overall: I want a webpage where I click a button which causes C# code to search a certain webpage and parse it. Based on the parsed information, it should automatically start searching multiple other webpages. All the while, I want the web UI to be updated with the progress.
Button Press and the client UI says "Searching..." Then the webpage is found so I want to display "Parsing..." Then the webpage parsing is complete and multiple other websites are searched at the same so the UI will display:
Webpage 1 updating...
Webpage 2 updating...
Webpage 3 updating...
Then when the Webpage 1 -3 are done updating, they change their progress message to Complete. I just started looking into ASP a few days ago and I have two ideas how to approach this problem: zy first idea was to use UpdatePanels and UpdateProgress because they seemed easy to get in there. However, the part of updating multiple webpage status messages at once doesn't appear to be possible since I can't have two UpdatePanels updating at the same time to make changes to the client UI. The one that is started second takes over the processing and the client UI isn't refreshed until that second asynch postback is complete. Ideally, there would be a way to refresh the UpdatePanel's mid postback............

I have the following:
<asp:UpdatePanel ID="upd" runat="server">
<ContentTemplate>
<script> alert("execute again"); </script>
<asp:LinkButton ID="go" runat="server" Text="Exec JS" />
</ContentTemplate>
</asp:UpdatePanel>
The first time the page renders the script is executed. If I click the button to cause a postback it doesn't execute again. Is there a way to make it execute the scripts again?

I have a GridView and Details view inside an updatepanel. When I set the page's default button to a link button in the Gridview, it works fine. Any subsequent attempt to change the default button to another link button(edit,update,etc) in the Details View doesn't work.

Re: Asp.net 2.0, VS 2005, Ajax 1.0
I am a newbie to ajax. I have started adding the ajax functionality to a current project. So added all the required contents in the web.config.
I have a master page in my project and I have a simple aspx page also using this master page.
All i have on the page is a script manager, an updatepanel and with in the updatepanel are three text boxes, a calender extender, an image button and a save button. When I click on the save button the first time the save button's event doesn't trigger but the second time I click it triggers. Similarly, the text_changed events of the text boxes dont trigger the first time.

This is working... no problem with that... The problem is this button, that I add into an UpdatePanel:

I just can't catch the click event of the button.

I have an asp button in an update panel within a TabContainer. I am having troubles accessing this button from javascript.
I need to access the onclick event of this button. The onclick event call a C# code from the code behind.
Without the TabContainer and Update panel I do
document.getElementById('btnID').click();
and it works.

I have a master page containing a ScriptManager control, and a Content Page containing a ScriptManagerProxy Control. Further on the content page I have an UpdatePanel control containing a GridView control and a server side button control. I have registered the button control as a trigger with the UpdatePanel control asynchronously and have set the UpdateMode of the UpdatePanel to "Conditional". I also have a "JumpLoader" control which is outside the UpdatePanel control. I have the following event for Jumploader wired up through Javascript. I am pasting the relevant sections of the code below:
