I have several functions running on a postback that can take a little time to complete.When postback is initiated I show a loading image with this code:
[Code]....
I want to be able to add code to this function so if user tries to leave at this point they are informed the operation is not complete.I found this code:
[Code]....
This works but I only want the code to be active when the loading image is active.I tried the following but it shows the alert message when the page eventually posts back:
I'd like to know how I can warn a user when they're leaving a page where they've changed data (i.e. "You have unsaved data on this page, are you sure you want to abanon it?"). For example, the page has a few dropdown lists, some textboxes, etc. I'd like to warn them if they try to leave the page before saving the data. How can I do this? To add to my confusion, I also have a dropdown menu control (skmMenu) on the page that doesn't seem to have any events I can tie into.
I have to warn the user when leaving the gridview row in edit mode without saving or cancelling the data. How can I achieve this? I have a javascript function which simply prompts the user when he/she leaves the screen which is not serving the purpose.
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?

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.
I 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?
I have a Gridview inside and UpdatePanel, Rows in this Gridview contains a DropDownsLists, each row has this attribute:
€œe.Row.Attributes["onclick"] = ClientScript.GetPostBackClientHyperlink(this.GridViewPJ, "Select$" + e.Row.RowIndex);", to select rows on mouse click.
If i click on the dropDownlist Contained by the row, this algo launch a postback, so I can never see this DropDownList deployed.I need a Way to stop this postback. Is teher a solution for this?
i have some textbox that i validate with a customvalidator control (only, and must be, server side function) and i have an imagebutton control for submit.I must stop the postback if there are some errors in the validation function.I set the validation property argumets.isvalid = false in the customvalidator function but doesn't work, the postback continue.i have tried to set the imagebutton property postbackurl = "" in the validation function but doesn't work.
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've tried an Update panel but that just grays out the text area after it does the update.
On my form I have a button that pops up a panel to select an option from. It does a postback to fill in a textbox with the selected data. The other controls such as other textboxes and dropdowns are reset. Any way to stop this? Or do I have to save the settings and set it back on the postback?
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 have a page with several asp buttons defined on a Master Page. I only wish these buttons to be activated when they are selected by the mouse click. I have one button on the content of the form, that is the button I want to execute if the user hits enter and it is selected or they use the mouse. So in a nutshell. how do I stop the buttons on the master page from executing unless the user mouses them?
