I have a textbox with an autocomplete extender.The user types in a few chars and usually gets a few to a few hundred suggestions back.And its pretty quick.This is on a formview control at the bottom by the paging. It is for a "Go to" feature.But it is returning the suggestions from the same list of search results from the previous page.(It's really the same page but I just toggle the visibility between the GridView Results and the FormView details).And if they select "All Tickets" its possible to get 5000 results from the search.
Now the autocomplete is really doing the same search as the search results did which is like 46 seconds. And then weeding it down further with the prefix (chars they type in the autocomplete textbox).I have a Return to list button. And I want the Button to interrupt, stop, cancel, abort, or somehow just not wait for the WebMethod to finish, and do a PostBack right away.Since btnReturnToList is a normal postback I can't really use PageRequestManager to check if in async or last postbackelementId or anything.
I'm using Javascript to create a DIV element and open up a new page by using onclientclick. This works great. Now, I need to write to it from the server side and this element must be created before it is posted back.
How do I get the javascript to execute before the postback?
Currently, I have to press the button twice because the element doesn't exist to write too on the first click.
To be clear, I need this to execute before the "OnClick" of the button.
Update: It looks like the Javascript function is called before the postback but the element is not updated until I run the second postback.
Update: Unfortunately it is a bit more complicated then this.
I'm creating a div tag in javascript to open a new window. Inside the div tag, I'm using a databinding syntax <%=Preview%> so that I can get access to this element on the server side. From the server side, I'm injecting the code.
I'm thinking this may be a chicken-egg problem but not sure.
UPDATE!
It is not the Javascript not running first. It is the databinding mechanism which is reading the blank variable before I'm able to set it.
I have this import function which can be changed by the client in his desired way.Now I want to code such that if the client tries to import his own data on the page and doesnot give the tags in the order mentioned below his import function should be stopped.
It shouldn't make any changes unless the tags are in the right format because the problem now is if the tags are not in the right format when client changes then its importing over the existing files and directing to an error page which I dont want it should simply stop the import function if they are nt in the order.the code for this function is below

I have 2 textboxes and a submit button inside a .net composite server control. I tried to only postback when submit button is clicked. I set autopostback = false for both textboxes. But either one still trigger submit button's onclick event by hitting "Enter" inside textbox. How can I stop postback by enter key?

When 'return false' is fired, I'm assuming that the function is stopped at that point and there's no need for exit fors and things like that?
I have an aspx page with two buttons, one of the buttons has an OnClick attribute to a function that should be run when clicked. When the other button is clicked there is an if statement checking if the page is a postback, if it is then I run some statements that need to be run when that button is clicked. That postback button works fine. However, the other button, when it's clicked the function it's supposed to call never executes, and the statements inside if (Page.IsPostBack) get executed instead. What can I do to fix this? Is there a way to make the button that calls a function not do a Post back?

I want to add a Checkbox which when Checked by the User will set a Session variable.
This Session variable will then be accessed on another page where it will include/disclude some SQL and therefore change the behaviour of a Search.

I have a JQuery Dialog that is opened when a button is clicked. The first time around, it should do a postback, but when the dialog closes and I click the refresh button of the broswer, it sends the data again and duplicates the data I just entered. Should I add a return false somewhere so it doesn't postback when the dialog is closed. Here is the script:

When I use a RadEditor I want to enable the editor's spell check (working thus far). After a spell check the user can either click on the radmodule (toolbar thing) to either "finish spellcheck" or "cancel." Which is all fine and dandy except the "finish" button causes a postback!! I don't want that at this point!! "cancel" more or less does what I want to happen - I mostly just want a "done" or a way to stop the postback.

I am using GeoMap in my website, and GeoMap is little below in Web Page.I am using filters in GeoMap, i.e., when user selects any station and clicks on "button", all the locations related to selection shows in GeoMap. But everytime when I filter and click on button, page loads and scroll upward then again to see the filteration result in Geo Map, I had to scroll down my page.I want that when I filter any station and click on button, page should stick to that GeoMap section. It should not go upward until user scrolls the page.For this I tried using "Update panel" but then GeoMap javascript is not working.
View 1 RepliesI want to stop postback if a certain value from a ddl is selected.
I've used VB to create a page whereby if a certain value from a ddl is selected then a hidden panel becomes visible. The problem is the likely answer to a majority of my ddl's is 'No' (or a no type response), however, even though the panel visibility remains false upon selecting No a postback still occurrs, the page refreshes and moves back to the top. I suppose this is a question with 2 possible solutions (or 2 questions rather)
1: Is there anyway of setting postback to false if selected value = No? A typical example of how my code appears is below
[Code]....
(i've used the value '1' to represenet Yes)
2: Is there a way of setting the page position after postback? As you can see in my code above i've set the focus on the next control (being a Radio Button) but i mean, is there an actual way of defining where the scroll bar is set?
