AJAX :: Stop ModalPopupExtender From Closing Every Postback?

Sep 25, 2008

I've placed a ModalPopupExtender in a WebUserControl to gather and display information to the user. The problem is that, whenever ANY button is clicked, or DropDown control is changed (i.e., anything that causes a postback), the ModalPopupExtender closes. This is not the desired behavior. Taking some advice from a coworker, I've placed a "dummy" button in the Web User Control in the same area of the OK/Cancel buttons, and set its display style to "none". Then I assigned the TargetControlID, OKControlID and CancelControlID to the dummyButton. After that, in the code-behind page I used an UpdatePanel1.FindControl(). FindControl() to delve into and retrieve the ModalPopupExtender, and use its Show() method to start it up. This worked just fine, but even with the OK/Cancel buttons set to a currently non-button, every control that causes a postback closes the modal window. I was also advised to try moving the control containing the ModalPopupExtender out of the UpdatePanel (I'm aware that was just grasping at straws), but this caused a run-time error. I'm am not a super JavaScript guru, and would prefer to find a solution that doesn't require an exhaustive journey into that realm. What I want is to explicitly open and close the modal window via my C# code, and not to have it close every time the user does something in it.

AJAX :: Buttons Not Firing After Closing ModalPopupExtender?

Nov 18, 2010

I hava an aspx page with a couple of tables and an UpdatePanel on top of the page. Everything on the page works fine until I show (from code-behind) the UpdatePanel (via ModalPopupExtender). The modal works OK after showing, but the problem is that when I close/hide it (using CancelControlID or a custom button with code behind) some control on the page stop firing events.

More exactly one Button and RowCommand on a GridView (both are NOT part of the UpdatePanel).

Here's the UpdatePanel code:


After this code is all the rest of the aspx page - including the Button and RowCommand that stop firing after showing and closing the update panel.

Where's the error?

AJAX :: How To Stop ModalPopup From Closing

Sep 1, 2010

I have a simple example of a ModalPopup with a panel that appears in the center of the ModalPopup and a couple of buttons in that panel. One of the buttons is a cancel and the other is an OK button. No matter how many other buttons that I add each one closes the ModalPopup. I need to keep the ModalPopup open so that I can run a few calculations then click a close button.

I am not sure where this error is comming from or even if this is the right place to put this. I have this event that fires when I click a link button in the Modal Popup, and yes the link button is set to not cause validation


When this event fires for some reason the modal popup window closes. How do I stop this from happening. If you need more code I will gladly provide it.

AJAX :: ModalPopupExtender Hides After Postback?

Apr 27, 2007

I am using the ModalPopupExtender to show a modal dialog. In the dialog I have a Do-Something button performing a very simple operation (copying text between two textboxes which are part of the modal dialog).

Everything is inside a UpdatePanel.

Every time I activate the Do-Something button the Dialog hides !Why ?

Is there a way to make the modal dialog stay between postbacks ?

Here is the ASP.NET code for my Modal Dialog:

AJAX :: Can't Get Width Or Height Of ModalPopupExtender After Postback

Feb 2, 2010

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:

AJAX :: ModalPopupExtender: After Postback, Client-side Show() No Longer Works

Mar 23, 2010

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.

AJAX :: Dynamically Created ModalPopupExtender In GridView Template Is Lost On Postback?

Nov 26, 2008

I have a dynamically create modalpopupextender within a template of a GridView. It is dynamically created on the GridView_DataBound() event.When I click the button on the GridView row it invokes the popup correctly. However, when the popup closes, a postback event occurs. Now when I click the button again, the popup doesn't appear. Im guessing this is since the page has posted back without databinding the modalpopupextender that was created as a result of the previous postback, no longer exists? So how do I get round this? If I rebind the gridview in the Page_Load of the postback then all I get is an empty gridview....

AJAX :: Stop AutoComplete SeviceMethod With Normal PostBack Button?

Dec 13, 2010

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.

How To Prevent Closing Of ModalPopup On Postback

Feb 3, 2010

I'm using the ModalPopupExtender control from the AJAX toolkit. This control extends a panel which contains a CreateUserWizard control. However, the validation of the CreateUserWizard control causes a postback to the server, which closes the popup. I'd like the popup to remain open, even after the postback.

AJAX :: ModalPopupExtender -- Fetch Data In Modalpopupextender

Apr 7, 2010

I would really appreciate if someone can find out what's wrong with this code.

Here is my question. I have textboxes in a modal popup extender (City, state, zip) and there is an image button search for searching the address from the database. All this functionality is within a control (.ascx file). This control is added to the page where it needs to be displayed and is being displayed when a user click the Address button (the code for it is not shown here). The method ShowAddressSearch() in the control is being called from the page and it displays the popup.

When the user enters any of the 3 values and hits search a server event is fired up and the result should be displayed in a grid. What is happening is, when the user hits the search button the server call is made and the data fetched from the db but the modal popup closes itself here is the code for this. I would really appreciate if someone can find out where and how popup is getting closed.

Stop Postback For RadEditor With Spellcheck?

Jul 7, 2010

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.
