AJAX :: ModalPopupExtender Preventing Codebehind Event From Firing?
May 21, 2010
Here is what I'm trying to do: Click a button on my page, which in turn makes (2) things happen:Display a ModalPopup to prevent the user from pressing any buttons or changing valuesCall my code behind method, hiding the ModalPopup when finished Here is the ASP markup:
I am performing the search event on the button click and showing the result in datalist inside the model popup on same button simultaneous. but when i am clicking the button it vill not showing the model popup.
In a button click, I need to be able to hide my ModalPanel and then continue running other code server-side. I currently have it this way:
[Code]....
It hides the panel at the of the event handler because that's when the page posts back. So what can I do to hide the panel and then continue running the rest of the server-side code?
Basically what I'm trying to do is the following:
1. Button_display in my webform simply displays my UpdatePanel via ModalPopupExtender.
2. Button_closePanel_Click will hide my UpdatePanel and then run some server-side code, which would display my UpdateProgress control.
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:
[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.
So I have a button on form that is supposed to execute some code-behind on a click event. To this button I also connected a Modal Popup Extender, which once you click OK, it goes away. What doesn't happen (and it should) is btnSendContactForm_Click never gets called.
Using the OnOkScript didn't help me either. I have tried setting the OnOkScript property of the extender, by calling a javascript that simulates the button click on the send button, but that only re-calls the modal pop extender, and a never-ending loop results everytime you click OK.
like to ask how to stop triggering event Timer_Tick when ModalPopup is already shown. I use the following code:
[Code]....
I'd like after 15 seconds the ModalPopup to show, but the timer go on counting and triggering Timer1_Tick event. This operation should happen on user basis. So, if one user ModalPopup shows and stops Timer1_Tick event, for another user on the website, the Timer1_Tick should work.
In the save button click I have the following code.
[Code]....
[Code]....
ModelPopupExtender pops up immediately after clicking the Save button without executing AddClient.How do I make it to pop up after AddClient has been executed?
I did some research and found two lines of code that would make the page postback. But, the method is not being called for the button. how to fire the onclick event with using ModalPopupExtender.
How can I fire a ModalPopupExtender on the SelectIndexChanged event of a dropdownlist?
I only want it to fire when a particular value is chosen in the list.
I tried leaving the PopupControlID value out and calling .Show() on my extender in the onselectchanged event, but it would not allow me to have a blank PopupControlID. If I set the PopupControlID to the ID of my dropdownlist, the popup fires as soon as I click on the dropdownlist control.
I'm using a ModalPopupExtender in my website, to show "accept/cancel" messages, and catch the user selection at the server side. I put two buttons (ok/cancel) at the panel that will be shown as a modal popup, add them a server side event handler, but it does not fire.
I got a strange issue with Gridview in ModalPopupExtender. The OnRowCommand event of the GridView control does not get fired on the first clicking on the button. It will get fired on and after the second clicking.
Unusual one this - IE7 and IE8 both behaving, but Firefox isn't. So, I suspect that I have done something wrong which I am "getting away with" in IE.....I have a DynamicPopulateExtender (DPE) and two ModalPopupExtenders (MPE). A Javascript function shows the first MPE (a "please wait" message) and then retrieves the DPE. When the DPE finishes retrieving, its populated event fires - that hides the first MPE and shows the second one which holds the results retrieved by the DPE.I know that I could have used built in functionality within the DPE to display the "please wait" message. However that would mean displaying the MPE before populating the DPE. I can't do that because I want to size the MPE depending on what comes back from the DPE.So, this is my Javascript:
[Code]....
As I said, it works fine in IE7 and IE8. In Firefox (and Opera and Safari), the "please wait" appears and then nothing else happens.
i'm using ajax tab container control and i have 4 tabs on it. and each tabs contains a datalist. and whenever someone clicks on the datalist he has to redirected on abc.aspx page.so for that i 'm using itemcommand event but facing problem whenever i click on datalist the event is not fired.
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 tabcontainer with a number of tabPanels. Each tabPanel has a placeholder tag which is set dynamically with relevant user control classes(ascx). When a button is clicked from a ascx within a placeholder, the onclick event does not get executed. How can I get this to work??
I have two problems with a databound AJAX Accordion. The Accordion looks like this:
[Code]....
The code behind has this subroutine:
[Code]....
[Code]....
The first problem I'm having is that this subroutine is not fired (I have a breakpoint in it) when the LinkButton inside the accordion is clicked. The Page_Load event fires and there is no error message, javascript errors, etc, but nothing else happens.
The second problem is that I'm not sure how to go backwards with the databind. I want to be able to make use of the UpdateMethod in the ObjectDataSource because I also have textboxes inside the accordion. I will have a Save subroutine that can be called but I'm not sure what code to put inside it.
I have a master page containing a ScriptManager control, and a Content Page containing a ScriptManagerProxy Control. Further on the content page I have an UpdatePanel control containing a GridView control and a server side button control. I have registered the button control as a trigger with the UpdatePanel control asynchronously and have set the UpdateMode of the UpdatePanel to "Conditional". I also have a "JumpLoader" control which is outside the UpdatePanel control. I have the following event for Jumploader wired up through Javascript. I am pasting the relevant sections of the code below:
I have a web application that shows a page containing between 6 and 20 UpdatePanels, contained with Custom Web (.ascx) Controls.
You can see an example of such a page here: [URL]
The problem I'm getting is that when the user FIRST clicks any of the radio-buttons on any of the controls in the page, ALL the radio buttons that have an active selection ALSO fire an rb_CheckChanged event (see application log below). On subsequent radio-button clicks, only that RB fires the event (as expected).
This behaviour is having a dramatic impact on performance. The page loads quickly, and a "normal" RB click provides an AJAX update correctly within 1 second. The problematic first RB click, however, takes up to SIX seconds to process, which is unacceptable from a user experience standpoint.
Developed in VS.NET 2008, ASP.NET 3.5. Also I converted the "Web Site" solution to a "Web Application" (pre-compiled) and got the same performance (still too slow). Release builds run only marginally faster than debug builds.
Why would a single RB selection change cause all RB's that have a "selection" set on them to also fire? (The "selection" is determined through database settings every time the control is populated, which is called from within the parent page control's Page_Load function. This selection is determined also at first page load, since all the controls get populated then, so why would the clicking of an RB cause them all to fire an event, and only once? That's what I don't get...)
I'm trying to get this accordian to get my data to display with a gridview in it, it renders fine, my datatable is being filled and it seem to bind but then there it no data and it skips my itemdatabound event in my code behind... Nothing loads!
if there is a bug with the databound event in vb.net or for this ajax control?
