I have a dynamically generated image placed inside an update panel. The image is generated with the Generated Image control (see here for more:
[URL]. This is basically a specialised httphandler linked to a normal asp:image, where the image src is generated dynamically. In my case, I use some GDI+ to dynamically generate the image, based on values from a database query.
The problem I have is that the image does not update when the update panel updates. The image does, however, update if I manually reload/refresh the page (i.e., hit F5). Why is is that some code fires during an update panel update, and not other code? And, more importantly, what can I do to make sure the image generation code does fire during the updatepanel update?

I have a Panel extended by a ModalPopupExtender. Within the panel is a button that uses javascript to display the width of the panel. I have two other buttons: one to show the popup and one to trigger a postback. All the controls sit within an update panel. Before triggering a postback I can show the popup and the button to display the width works fine. After I cause a postback, though, it always reports 0. Here is the page I have:

I work with ModalPopupExtender (ajax control toolkit) asp.net
that is to say that a popup appears which contain one panel with 2 DropDownList (DropDownList1, DropDownList2)price starting from DropDownList1 the DropDownList filled due to the code behind.
My problem is that when I click on the DropDownList1 ModalPopupExtender that contain the Panel is gone because of AutoPostBack = "True" of DropDownList1.

firstly i am not really an ASP.Net developer but i do work in C#.
Anyway one of the application that i develop has an ASP.Net section and i need to amend it.
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.
So i have 2 Pages - Page1 that has the Checkbox on it -

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 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 what I believe is a pretty common/boring/generic implementation of a ModalPopupExtender. I'm using client-side JS to show the dialog when the user clicks a link, and hide it if they click "cancel". I only do a postback if they truly want to save the data.
I can click the link to show the dialog, then click the cancel button to hide it, then click the link to show it... ad infinitum. If I decide to save the data via a postback, everything works well, and the dialog is hidden as a result of the postback, all as expected.
However, once the postback completes, my client-side JS show() never works again. Any attempts to click the link fail quietly; no error messages, the dialog just never shows again.

I have a master page that has a usercontrol on the left side of the page with a dropdown. When the user selects a value from the dropdown I need to load a different aspx page. The new page has a similar (but not the same) looking usercontrol on the left and different content on the right. How can I do this? Also, when the new page is loaded the dropdown must remember its selection.

I'm using the Ajax control toolkit Combo box for filtering purpose. If the number of items in the combo box is more and when i try to select an item in the drop down list, the scroll bar in the list automatically flickers in Internet explorer.I read the known issues section in the Asp.Net Ajax control toolkit website, and they say that When ListItemHoverCssClass is specified and the ComboBox list is scrollable, highlighting a list item will cause the scrollbar to flicker when using the Internet Explorer web browser. To avoid this issue, do not specify the ListItemHoverCssClass property.Am not using any ListItemHoverCssClass Property but still it flickers. Please help me on any work around to solve this. I know Auto Complete extender is a best solution instead of combo box, but the clients need combox that should list everything along with editing in the text box.

I have a situation where I need to have close to 30 drop down lists on one form. The user also wants the autocomplete functionality. I decided to use the ASP.NET AJAX control. So that the page will load faster I hide them until they are needed. But, as more and more become visible the postback time is getting longer and longer.
I know this can be fixed, but I'm not sure how. Can anyone give me any advice, point me to some articles? Do you have a suggestion for another method of doing what I need? Maybe, I shouldn't even be using ComboBoxes for this?

I've a page with a Masterpage.
In this page there is a Panel with ID : "ModalPanel".
There is a ModalPopuExtender on "ModalPanel".
I show this panel (ModalPanel) from code-behind. Works very well!
If in the same page I create another Panel "ModalPanel2" with another ModalPopuExtender : the second panel don't works!!!Why?!
The "ModalPanel2" is always visible! And don't has the behavior of a Modal Panel (like the first one).
