C# - Using JQuery Instead Of AJAX To Simulate UpdatePanel Functionality?
Jun 6, 2010
I am developing an asp.net web application and stand on jQuery plug-ins for any aspects of my Interface. But unfortunately I have to use AJAX only for its UpdatePanel to enable partial rendering. Is there any way to use jQuery for partial rendering and act such an UpdatePanel?
Here's my situation:I've got a parent UpdatePanel (with ChildrenAsTriggers set to false and UpdateMode set to conditional) that contains a webpartzone which loads webparts with user controls inside them at runtime. Both the parent UpdatePanel and the child UpdatePanel (also set to ChildrenAsTriggers=false and UpdateMode=Conditional) obviously have triggers set up that are relevant to them.
The problem is that whenever the parent UpdatePanel fires an asynchronous postback, the child UpdatePanel in my user control gets fired off as well thereby causing my user control to be re-rendered. I don't want this to happen. Outside of initially loading the user control, I want that user control to only get updated/rendered again when a trigger inside itself is fired,not when the parent (outer framework) fires off one of its triggers. A ParentAsTrigger property (set to "false") for the child UpdatePanel would be perfect if it existed.
Note that I've tried eliminating the child UpdatePanel inside the user control and then loading the triggers for those controls to the parent UpdatePanel at runtime, but that doesn't work because the user control is being invoked within CreateChildControls() -- I get an exception when I attempt to do that.
If I set up a repeater that has LinkButton controls, an UpdatePanel works great. If I add child elements to the LinkButton,such as SPAN, the UpdatePanel stops working as expected. If you click on the area of the LinkButton everything still works, but if you click on the area of the SPAN inside of the LinkButton, you get a full PostBack.I've tried setting ChildrenAsTriggers to true and a few hundred other things. Nothing seems to work. I think the UpdatePanel sees that the "click" event happened on the SPAN and doesn't know to capture it for an async postback.
When the user click on TreeNew button appears the modal dialog, then he/she choose an option an click Ok button to do a postback.I need that the server side execute TreeNew_Click method: How can I do that?
If I use __doPostBack('TreeNew', '') it throws me the following error: "Object expected".
UPDATE:I found the origin for the error: the function __doPostBack is not defined. I'm not going to delete the question because I think Chris Clark's answer is so interesting.
I have an UpdatePanel with a MultiView inside. I am using jQuery to call the server to run some logic and based on it, change the view in the MultiView. The problem is that the updatepanel is not getting refreshed.
I am trying to integrate a JQuery script to have a video lightbox (with a youtube video) inside an asp.net updatepanel that does a postback before the lightbox is loaded. The code is perfectly working if it is put outside the updatepanel Bascically in my aspx page I have an updatepanel with two panels, one of them is initially not visible and it contains the ligthbox :
I have a button inside the updatepanel that if pressed makes the pnlVideoLightbox visible. Then I just click on the thumbnail that should fire the lightbox but the browser redirects to the youtube website instead of firing the JQuery code.
I have a webform which has a textbox called "Branch ID" and onblur of that textbox it shows "Spinner wheel" animation after the field and checks the Branch ID in table for existence using Ajax call and Ajax call returns the text if its available or not and after finishing ajax call it hides the animation. Since I've put update panel before the textbox my jquery code which hide/unhide the spinner animation is not working. here is the code
Here is the WebService Code
Now how to hide the animation as jQuery not working inside update panel.
I've a dropdown and a listview inside an updatepanel (Master/Child relationship) so based on value selected in dropdown the listview gets populated. The Listview allow user to perform Edit/Insert/delete of records. I have to implement a scenario when a user is editing/inserting a record and if he tries to navigate away/change the value in dropdown he should be prompted to save the data and if he choose yes in JS Confirm Dialogue then the currently edited/inserting record should be saved (for which i'm trying to mimic the click of the update/insert button using js). I've attached change eventhandler of dropdown using JQuery which is getting called properly bind. [Code]....
This code gets bind using Sys.Application.add_load(saveChanges); I also tried the following Sys.WebForms.PageRequestManager.getInstance().add_initializeRequest(saveChanges);Sys.WebForms.PageRequestManager.getInstance().add_endRequest(saveChanges). The eventhandler gets called correctly but the click() doesn't work! Also the reason I'm calling click() method of button is to perform the validations via RequireValidator/RangeValidators.
Now i am having two dropdown one is asp dropdownlist and 2ND is MultiSelect-DropDownList-with-CheckBoxes. 2nd dropdown is populating on selected value of first.On page load it works fine. Now, on change of value in dropdown, selected index change 2nd dropdown (MultiSelect-DropDownList-with-CheckBoxes) fills but i see a list box instead of dropdown.
i'm just getting started with asp.net and ajax. My question is : is it possible to make an ajax request and simulate the server response in the code behind. in other words can the request be sent to the code behind of the same page? if it's possible haw can i perform this ?
With Repeater I am doing All functionality(Update And Delete).On Item command.But On Iteam command My page rfresh every time And it take time Reason of post back.But i want to do all functionility with Jquary So my aplication performnce increase.And reduce response time. My mail Id Is firstname.lastname@example.org.If possible send me example on my mail Id.
I load an aspx page in iframe inside a jQuery UI dialog to update some data, and after dialog is closed I need to update an updatepanel in parent page. how can I do that? to be more specific, there is a datagrid in parent page and after I edit data in a dialog modal iframe, I want to update the row in datagrid.
I am using multiple user control in my web page. Each of these usercontrol has $(document).ready() method. Because i am using an update panel, i am binding all the events again in end_request event. But I dont want to do that in all my usercontrols. Is is possible to do this at a common place(only once)?
May be it's the same question i have i asked before but the issue is the same and i didn't find any resolution so i have to write it again with the expectation that it would be solved this time.My question is i am using two list boxes and one list box is populated by putting the list the list item tag in listBox1 on aspx page and i want to implement functionality like add and remove between two list boxes i mean removing an item from listBox1 should be added to second and removing an item from second should be added to first. While i tried my own but the problem is that on post back it come to same condition. I have implemented the add remove functionality by using the jQuery but the problem is that on post back it come to same condition so i want a good solution for this ow should i implement this so that on post back it retain it's value please ris me off from this issue.I found some solutions for this on Google that i should make some other class which will extend ListBox base class but i couldn't understand that and how should i code for that so please explain me that code if possible.
