AJAX :: Multiview Dynamic Control Disappear Into A Update Panel?
Jan 12, 2010
I have a page with an UpdatePanel in wich I load the menu selected Layout pages, and the layouts loads its contents dynamically.
It works fine, but when I load a Layout that has an Multiview control, the code behind of the Layout don't come in into the if(!Page.IsPostBack), ok, I fixed it with if(multiview.ActiveViewIndex==-1) multiview.setactiveview("viewName").
In the Multiview I have a ListView, in the listview I have Linkbuttons that opens another view and shows the information of the specified row dynamically.
when I click in the link so the page disappear from the update panel... why? I do not a full postback of the page, so I think I don't need to reload that page on the update panel... Right?

I have a page that is mostly dynamically built in the page load of my VB.net code behind page.
The issue is that I made a change to the page and added a button that redirects to a secondary page. When the button is clicked there is a very noticeable lag until the button click event fires because the page is being rebuilt every time.
I had not wrapped the code in the load event in the If not ispostback.... because I have dynamic controls that the user interacts with and I need the page to be rebuilt when the user clicks them.
The dynamic controls are clickable table cells. I did some looking and I found that the RegisterPostBackControl. I thought this would be perfect but, it does not although I maybe using it incorrectly.
Here is the code flow.

I have an invoice form that I want to be able to populate using an ajax control. There will be a section at the top that will allow the user to select a record from a db or create a new one. This section will have several criteria types that can be used to select the records. They will be able to choose the record by the invoice id, date of service....etc.
I'm trying to decide between using the dynamic populate extender and the update panel for the different areas of the invoice. For example, there are different sections that show the customer's info, notes for the invoice, the services performed and the totals for the work done. I want each of these to be dynamic. For example, when a new service is added to the invoice the total is updated. Or if an existing invoice is opened these fields will be populated for that record.
I'm trying to decide if the dynamic populate extender or update panels should be used for each of these dynamic sections of the invoice. It seems like either can be used but I'm not sure which would be better.

Development environment: VS2008, Win XP
Iam working on a web form that incorporate ListView control with Ajax RoundCornerExtender.On my machine everything works fine, and looks okay. After uploading the page to the host server the ListView Item DIV with the round corners looks broken, I contacted the host server support and they asked me to check for version issues, I reinstalled the Ajax Control Toolkit as well as the .Net Framework 3.5 but still no change. When I change the ASP.NET version on the control panel from ver. 2.0 to ver. "2.0 Integrated pipeline" (they say its ver. 3.5) all the Ajax controls disapear from the page.
One more thing I noticed, when the ASP.NET ver. on control panel is set to "2.0 Integrated pipeline" (3.5) and I execute the following -
Response.Write(System.Environment.Version.ToString)
I get ver. 2.0.50727.4200 which is ASP.NET 2.0, why things looks okay on my machine and look different on host server ?

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've exempted the irrelevant bits of code. Essentially, I am trying to change the URL of an image control inside of an update panel inside of a custom user control from a function called inside an update panel from my main page. Using UpdatePanel.Update() isn't working: I end up waiting for the next full page POST to occur before all the updates I make to CustomControl from buttons within the main page's update panel are visible. I verified that Update() was being called via the debugger: there are no issues in that department.
Here, you can see Custom Control and the Button declared. The button is in an update panel to avoid giving a full POST and causing the whole page to reload.
<cust:CustomControl runat="server" ID="CustomControl1">
<asp:UpdatePanel runat="server" ID="UpdatePanel1"> <ContentTemplate>
<asp:Button id="Button1" runat="server" OnClick="DoStuff" />
</ContentTemplate> </asp:UpdatePanel>
This control stores images within their own seperate update panels because rerendering the images is very slow (it requires processing arrays of millions of datapoints) and the user only ever needs to modify one image at a time. I'm using Image1 as an example.

I have a multi view which contains a view which contains a panel. the name of this panel is "Panel1"I have the following code and my HTML does not display in the rendered page. Any idea why this isn't working, i must be doing something wrong? sw = simple html statement, any would produce same result.
String mstring = sw.ToString();
Panel1.Controls.Add(new LiteralControl(mstring));
i am using dotnetnuke also, not sure if that is where the issue is.

We have two update panels on our webpage. Now first update panel is having button cancel. While second update panel is having a file upload control.
Now if the user uploads a file that is going to upload in about 2 mins, and in between, say after 30 seconds the user clicks the cancel button, the upload taking place in update panel 2 should stop.
How do we achieve this ?

I use Update Panel in some parts of the page and when the user click on Insert Button, I want to save all the data which is got from the Update Panel's controls. But the data from the Update Panels' controls are not saved in the database. When I debug, the data are in the textbox and hidden field, they are in the Update Panel. But they are not save in the database. Other values, which is not in Update Panel, are saved in the database.
How can I take the data from the Update Panel?
Here is some of code.

I have an accordion control in my web site. And in one of the panels, I have a drop down list box where, when the user selects an item, it updates the labels right below the ddlistbox. I have it so that it maintains the scroll position when the ddlistbox has an autopostback, but it's very obvious that the whole page posts back. My question is, can I/should I just enclose the ddlistbox and the labels (and a couple of text boxes) in an AJAX update panel? I already have a ToolScriptManager (because of the accordion control), so I don't need to have another script manager, right? I can just put the update panel (with the other controls inside of it) right in the accordion panel, right? Then when the ddlistbox posts back it won't have the delay of the whole page posting back? And it'll still execute the event handler for the listbox selection change? Does this sound right? I'm just looking to make the post back "invisible", and I would like to do a partial postback of just these few controls.

I am trying to wrap my head around update tabels, the thing thats boring me is if i should use one or multiple panels. When i load a control into my update panel should that control have it's own update panel? Or will it use the updatepanel it's loaded into? Is it even possible to dynamicly load a control into an updatepanel and do async post backs from there? Let me paint you a picture:

I have 2 user controls. The first user control generates custom paging and assigns the output as a string literal. The second user control is a simple repeater which uses values from the paging control via a query string to decide which relevant chunk of data to retrn.
The custom paging control is embeded in the custom reapeater control. In my my page, I simply call the customer erpeater control and everything works treat.I now want to add update panels to this but I can't think where to start.
The paging control looka like this.

working on .net framework 3.5 with vb
I have displayed 50% of text on label control..then i have given a dynamic link to Read More.
when i clicks on Read More it passes query string of id of that content to same page which shows full content.
Now, what I want is when I clicks on Read More link the page postback then loads the full content. So, is there any way to avoid postback using update Panel for any links generated dynamically on Label control.....?

Having a bit of trouble here. I know that if you want to use a fileupload control inside an AJAX update panel then you need to create a trigger for the control that performs the uploading postback to the updatepanel, but the problem is, I have an update panel that contains web usercontrols. I therefore can't add a trigger to the control(FileUpload) directly because it exists in the web control.

I've been wrecking my brain on how to solve this but I'm all out of idea. I have a FileUpload control within an UpdatePanel. I have a button, let's call this btnSave, that saves the FileUpload.PostedFile into an sql server. What happens is that when the btnSave is clicked, I would save the file to a ViewState as well as upload it to the sql server. I also have an ImageButton, call this btnDel, that clears up the ViewState that holds the File in the viewState. This btnDel is an Asynchrounouspostback trigger to the UpdatePanel that holds the FileUpload control. If I browse a file, click on btnSave, everything would work fine. However, if I browse a file, click save, click on btnDel, browse anotherfile using FileUpload, and click save, sometimes FileUpload.PostedFile has a file and sometimes it is null. I'm really not sure what's causing this. I know that there is an issue of incompatibility if btnSave is made to be an asynchronouspostback trigger to the updatePanel. I don't see how making btnDel an asynchronouspostback trigger could affect this.
If I do take out the FileUpload control from the UpdatePanel and remove btnDel as a trigger, everything works fine except a postback is generated, which the client does not like.

I have block of code that consists of a textbox a button and a dropdown. The text entered in the text box filters the dropdownlist when the user clicks the button. The Ajax works great when it is in a simple page but if I put the same code in a User control I get flicker.

when I click on a record in gridview it should call the SelectedIndexChanged event and do some operations.
SelectedIndexChanged event is working OK, but when I put the gridview inside ajax updatepanle SelectedIndexChanged event will not response even if I add AsyncPostBackTrigger trigger for SelectedIndexChanged event.

I am using an update panel in my ASP.NET code. My problem is very simple and straight forward.
There is button which send some group SMSs to different users.
I used update panel to show UpdateProgress on my page.
On click of the button I wish to hide the button and some other labels on the page.
The problem is that after clicking the button everything else works find but these control's state does not change.
Funny thing is when i click the button, it does some checks and update a label text with error resultant values, if error is there. It works fine.
But after removing the error, I click the button once again to do the processing. Then everything on code works fine, but the label which was showing doesnot hide.
Code is as follows:
