Update Panel Not Working In User Control

Nov 12, 2010

I am fixing issues in a project where I was not able to figure out a solution for the below problem. There are multiple user controls in Main.aspx page. First one is header.ascx which is added directly in .aspx page. and the others are added dynamically from Page_Init event. Basing on the hyperlink clicked from the menu on the left side of the main page, the respective user control is displayed.

Now, If I try to add script-manager/update panel inside any of the dynamic user controls, the respective user control page throws error. I have noticed that the header.ascx control is using scriptmanager. Is it creating the problem? How to handle this kind of issue?

AJAX :: Update Panel & Update Progress In User Control / Multiple Instances On Same Page

Feb 16, 2010

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?

AJAX :: Using A User Control's UpdatePanel.Update() From A Page-level Update Panel's Function Call?

Jul 14, 2010

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.

AJAX :: File Upload Control Not Working In Update Panel?

Feb 15, 2011

I have 3 upload controls ,one listbox and two button controls in page. One button control named Attach has the code to add the files to listbox form 3rd file upload control and the 2nd button control named Save has the code to save the files of 1st and 2nd file upload controls in application folder and items of listbox to database.

The issue is couldn't maintain the state of 1st and 2nd file upload controls after browsing the files to file upload controls and clicking on Attach button control to add file name to listbox which was browsed by 3rd file upload control.So i placed the 3rd file upload control, Attach button and listbox in update panel but its not working. My requirement is when clicked on save button files of 1st and 2nd file upload controls in application folder and items of listbox to database, but 1st and 2nd file upload controls will loose the files as soon as Attach button is clicked to add filename of 3rd fileupload control to listbox.

AJAX :: How To Update Panel With User Control

Nov 5, 2010

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.

AJAX :: Odd Behavior On Setting Focus In User Control With Update Panel?

Nov 9, 2010

I'm having a bit of an issue in my ASP.Net application moving focus from a textbox in one user control to a text box in the next user control on the page after postback. I've searched high and low over the last several days to find a solution but, for whatever reason, have been unable to do so.

I have a page that has user controls loaded dynamically to allow a user to enter data.The number and type of user controls loaded to the page is determined at run time based on a database query.It is possible than many controls of the same type can be loaded. Each user control has its own update panel. Within the update panel of each control is a regular asp panel. Inside of the regular panel there are at least 2 server controls (any other controls that may exist in the user control are not affected by this issue) - a text box and a button.The defaultbutton property of the regular panel is set to the ID of the button within the user control. The desired behavior is to allow the user to enter data into the textbox on one user control hit enter to save the data on that user control the application will set focus to the textbox of the next user control on the page after the data from the "current" user control has been saved. Other considerations;

The application uses master pages. We make extensive use of ajax and the ajaxtoolkit in the application. I am using Visual Studio 2010 and .Net 4 The issue - when first entering the page, one can enter data into the first textbox and press the enter key. Data from "current" user control is correctly saved and focus is correctly moved to the next user control on the page.

Data can be entered into the textbox of "new" user control and when the enter key is pressed, the data is correctly save. The focus appears to move correctly to the next user control on the page.Data cannot be entered into the textbox of the control. Pressing the enter key will not save the data (because none was entered) but the focus will move to the textbox of the next user control on the page.

Data can be entered into the textbox of the user control. When the enter key is pressed, the data is correctly saved and the focus appears to move correctly to the textbox of the next control on the pageBasically, steps 3 and 4 are repeated until the end of the user controls on the page, alternating between being able to enter data and not. Other items of note When one is able to enter data into the textbox of a user control, one can correctly tab through the textboxes of each user control until the end of the page When one is not able to enter data into the textbox of a user control, pressing the tab key will take the focus to the address bar of the browser.

I created a much simplified example of the scenario described above and was able to consistently reproduce the "bad" focus behavior. All of the ajax toolkit controls and code where stripped out of the sample to rule the toolkit out as a cause. The behavior still occurs without the toolkit.

I am including the code for default.aspx and WebUserControl1.ascx.

AJAX :: Hosting Windows User Control In A Webpage Inside An Update Panel

Jun 8, 2010

I am hosting a Windows User Control in my web page using <object> tag. Everything works fine when the control is outside the updatepanel and is independent of other web controls but when I move the control inside the update panel, it doen't load the user control properly.

<object id="myBrowser" classid="http:MyBrowser.dll#MyBrowser.UserControl1" height="20" width="400" VIEWASTEXT></object>

why it doesn't render the control properly and what can I do to fix it?

I tried moving the user control outside the update panel but since this user control is shown/hidden dynamically and is rendered based on other web controls which are inside an Update Panel, the user control is not shown at all.

User Control Inside Update Panel Causing Full Page Postback

Jul 13, 2010

I have a user control with linkbuttons (used for paging) and a repeater inside an update panel. The paging works correctly, but is causing a full page postback every time I click through to the next page.

The update panel looks like this:

[code]....

So far, I have tried adding an async postback trigger for the user control, which does cause an async postback but does not update the rest of the text in the update panel. In otherwords, the async postback occurs and the next page shows up, but the original text in the repeater is there as well just below it.

I have also confirmed that I have IDS set on my linkbuttons, since that can trigger a full postback inside an update panel.

I have tried changing the update panel mode (Always, Conditional, ChildrenAsTriggers, etc.).

None of it makes a difference - the only thing that actually causes an async postback is to use the trigger, but then the rest of the content in the update panel is not updated, so I get duplicate content.

'Loop through the update panel controls on the page and find the one that is involved in the postback (isInPartialRendering)

I have a form that has a table(TABLE1)...and inside TABLE1 i am linking to a sql data source....at the bottom of the table i have a 'Add' button.

When the user clicks the add button...a modal popup appears (POPUP1) and inside the POPUP1 the user can click a link that can add a user...when the link button is clicked...a panel within POPUP1 is set to visible = true.

I have one update panel around the whole table and the add button...when i click add and then click the link to add a user....the modal popup disappears.

C# - Update Panel Working Very Slow?

Mar 20, 2011

I'm writing an app in which user can register. While registering the one may choose several options and according to these regiester fields are visible or not and are required or not. I came up with an idea that all fields will be in in the updatePanel and when users changes registration options I would set visibility of these fields on the server side.

It works but incredibly slow and whats more on the FF I have the given error:

The state information is invalid for this page and might be corrupted

3 checkboxes with other fields are in the updatePanel

Each field is in dl tag with runat="server>

I had to do it like that cause for "required" option I simply add css class to this dl (need in in javascript validation. If field should be visible I set visible="false" for given dl and then that field for example FirstName with title and so on isn visible after postback.

Am I doing something wrong ? Why does it take so long (~4 min on localhost) and in firefox it doesnt really work (when I use debug I think that process completes without errors on ff, I dont understand that at all :)

If update Panel is so weak what would be other option to change visibility and adding required class to all dls. Logic is quite complicated and has to make query to DB so simple javascript would be quite tricky.

Oh and I'm using ASP.Net and cant upgrade on this project.
