AJAX :: While Typing Some Text In Search Lable Of Listsearchextender The SelectedIndexChanged Event Is Fired And The Page Is Posted Back?
Jul 9, 2010
In my current web application I have a listbox containing large number of elements. I have used an ajax listsearchextender to help the users in selecting the elements. I have set the autopostback property of listbox true. The application is working fine as expected in internet explorer. But in firefox while I am typing some text in search lable of listsearchextender the selectedIndexChanged event is fired and the page is posted back. So I am not able to selected the item properly using list search extender control. Can you please suggest me how can I stop the selectedIndexChanged event.
A breakpoint is set on FillForm() and this method is called two times but I can't explain myself why this happens. I have client side javascript code, when the form is being send, the onsubmit method is also called twice... Where do I have to search?! Is it a (known) bug? Think I could get it to work with this Thread: [URL] But why is the event fired within the onblur-event when it's fired anyway??
I am using Asynchronous File uploader ajax toolkit control.I want to get knowledge of whether page is posted back due to File uploader or not in Page_Load event of my aspx page.
For that i tried to use Page properties IsAsync, IsCallBack but even page is posted back on responce of File Upload these properties are false,only IsPostback property is True.
Why IsAsync and IsCallBack properties are false ?
I was thinking that since this control upload files Asyncronously, so atleast on File Upload IsAsync property should be True.But that is also false .
In our asp.net web application we load the dropdown list boxes in the page load. We than set the SelectedValue of each dropdown list box to an object from session. We have event handlers for many of the SelectedIndexChanged events of the drop down lists boxes, but these do not get executed when we set the selected value programmatically.
Someone else mentioned this is by design, and only when a user manually changes the drop down list selected index, will the event get raised.
I would think this is a common scenario of wanting the selectedindexchanged event handled when setting the selectedvalue/selectedindex/listitem's selected property, of a DropDownList. What is the suggested way to handle this? Is there a significant drawback of creating a custom control inherited from DropDownList that has the functionality of raising this event when changing the SelectedIndex or SelectedValue?
I've a asp:TextBox and a submit button on my asp.net page. Once the button was clicked, the TextBos's value is posted back. I'm going to keep the the posted-back text value into session, so that other child controls can access to the value during their Page_Load. However, I always get NOTHING ("") in the Page_Load method, and I can read the text out in the button click handler. I know that the "button click event" happens after the Page_Load. So, I'm asking how can I "pre-fetch" the TextBox.text during Page_Load?

I have a listbox with the listsearchextender as follows...
[Code]....
My problem is that when I click in the listbox the prompt is "...h". When I start typing it changes to "...x" where x is the last letter of the listbox item.
Whatever server Control we take on aspx page while in coding phase, all those controls are converted to html controls through the asp.net engine and sent to the requesting web browser. That's fine.
Now, all the controls that are rendered on the browser are html controls. I am bit confused that how after pressing any button (Or any such control that post back pages) page is posted back to the asp.net engine. How such html controls comes to know where (address) they have to go?
If the grid column is clicked to sort i dont want to retireve data agian, i can get it from viewstate, but i dont know if that triggered the post back or if the ImageButton on the page triggered it
It is about ASP.NET MVC3. I have a page with at the top some search criteria and at the bottom the resulting data. The user can type some criteria and use a submit button to retieve data. In my controller, I have an ActionResult function for managing these criteria and return to the same page with a ViewModel class filled.
The problem: the user can click on a line in the resulting table for viewing a detail page. On the detail page, he can navigate to an edit page for editing data. On this page (edit data) I would like to able the user to go back to the search result page (in fact: navigate back two times). What is the best way to proceed? If I "simply" use an ActionLink (without posting data) to my search result page, it will simply display an empty result page with empty search criteria. Maybe I need to keep my search criteria in a session variable? I don't like this kind of thing...

I have a usercontrol and in that i have a dropdown. i need async postback for dropdown selectedindexchanged event. i set the AutoPostBack=true for dropdown. Eventhough the event is not getting fired.
I have a DropDownList in a TabPanel.In a separate TabPanel I have a control wrapped in an UpdatePanel which is tied to the SelectedIndexChanged event of the DDL in the first panel.At run-time I get an error from the UpdatePanel indicating the DDL control does not exist.
I moved the UpdatePanel into the same TabPanel with the DDL.The DDL has AutoPostBack set to true and the event for SelectedIndexChanged never fires.I also turned off Validation in case a validator was capturing it.This all worked fine before I "tabified" this page.
