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.

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 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.

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.

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'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.

I created a .NET user control to work as a DropdownCheckbox and added Jquery to give the sliding and hide effects. The code is as below:

This control works fine in a normal page, but once I put it inside an update panel it doesn't work. Is there a work around or simply I can't use JQuery inside update panel?

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.

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.

Does anyone know a simple way to determine if a user control is contained in an update panel that was triggered for async postback?
At the moment, the only pseudo logic for this I can think of is?
'Loop through the update panel controls on the page and find the one that is involved in the postback (isInPartialRendering)
'Try to find the user control as a child of the update panel

I want a Javascript function to be called automatically after the UpdatePanel has finished updating its contents. I don't want to use:
Sys.WebForms.PageRequestManager.getInstance().add_endRequest
and then call a JS function. This is because I have more than one update panels and I'll have to write all the condions to check which UpdatePanel was actually called and then do something. Can something be done using Triggers in UpdatePanel. Kindly let me know how this can be done.
It would be great of you could post a sample code too.
