AJAX :: Update Panel Surrounding Whole Listview For Update
Apr 27, 2016
Is it possible to use a script manager, then surround a listbox with an update panel, so that when ever any button is pressed like insert/edit,delete, cancel that it will trigger on these buttons and do an ajax update on the whole listview, if so how ...
I have a ListView control that is inside of an update panel. I have a Button control that calls code behind when clicked and I have a trigger in the update panel that is triggered based on the click event of the button. The button that calls the code behind and inserts a record into the database works fine but I get a full page refresh and the ListView Data is not updated as expected. I then can go to another page, come back and the new data is there. I'm not sure what I missing. Please see the code below.
I have one update panel inside updatepanel i have one dropdownlist .When i change dropdownlist value so as per value button1 which is out of updatepanel not visible =true or false as per dropdownlist value.
I have a formview in Edit Mode, within an update Panel all and these arewithin a Modal Pop Up extender.On clicking Formview Update button, I want an image to appear within the pop up.I have put the image within another panel1 and runat server.For some reason the image is not showing on clicking update button.
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.
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 am building a system for a school project. I currently have several Update Panels on the page that have many different controls on them. I also have a single Label control that i use to display messages to the user. I would like to have this label within an update panel also but there are literally hundreds of triggers that would require it to be updated and i dont want to type an absurd number of triggers for this one control.Is there a way for me to have this one panel update regardless of what happens?
i am confused about the fact that if partial update of dropdowns is possible through Update Panel ,then why we should use asp.net ajax Cascading drop down extender ,that has made same task bit complex by making callback to web services ? what is difference between using update panel and cascading drop down extender ?
I have update panel , in update panel i have one button control which exposes onlientClick event ( it dosent have click event to do postback to server).
and i have one updateprogress panel. So my problem is though i'm performing operation on client side , internally the async event is firing and making updateprogress panel to act (having rotation gif image) which i dont want , as it rotates for 10-15 sec more even after the operation at client side is done !
I am having a weird issue with the update panels. I have an update panel in UpdateMode = Conditional . I have a dropdown list and a grid view..the gridview has to be updated ÖnSelectionChanged event on the dropdown.
The issue here is on changing the selection on dropdown, the onselectionchanged event is triggered, new data is grabbed, bound to gridview..but does nt update the update panel even after the updatepanel.update();
when postback occurs due to update panel's child control then in page load event how can i know that it was dut to update panel ?i.e., i want to differentiate between general postback and postback due to update panel's child control in page load event .How is that possible ?
I have written a Crystal reports web application, that prompts ths user for parameters and then apply them and exports the report to a folder as .rpt and then display the report.
I prompt the parameters on one screen and then display the report on another page. I have the AJAX update panel and update progress controls in the parameter page. When the user enters the parameters and click on ok, I export the report and then loads the report to a session report document and transfer the user to the second page where the report is displayed. I use the following code to do transfer to the seconds page.
I have excluded the report load and parameter assign code here.
In the second page I have the following:
rptViewer.reportsource = Session("rpt")
My problem is this works one time and then stops working the second. What I found out was it comes to the statement:
But it does not even load the show.aspx page. It stays on the parameter page. There are no errors displayed. I could not see any errors when I debug the application also. And out of the blue it works sometimes. And if I remove the update panel and progress control, my report works all the time.
I am working in asp.net 4.5 with VS2013. I have two usercontrols in my aspx page and in my first usercontrol i have gridview with button inside update panel and if i press the button it should pass the value to second userconrol and based on the value i will do some db operation to bind the controls in second usercontrol.
I am wondering is it possible to achieve using AJAX? I need to do this with partial postback without posting entire content of the page.
