How to avoid modal popup closing on postback ?.. I have a popup window displaying a grid view after a buttonclick event. but the pop up closes after the button is clicked ?? Can anyone help ??
Look at this question it may help you, just recall the modalpop.show() again.
How do I prevent the closing of modal popup window(ModalPopupExtender) on postback?
In general, you will need to preserve the modal popup state in order to reinitiate it again after the postback.
What I can suggest is to setup a hiddenfield control that only holds the state of your modal (0-1, true-false, whatever you like), and with Javascript, it's easy to change the hiddenfield value in order to reflect the current popup state.
When the page get posted back and reloads again, setup an onload javascript function that checks for the hiddenfield's value, and then react based on it to show the popup again as soon as the page is loaded.
You can use an asynchronous postback or set a flag and show the dialog again after the postback.

Textbox inside modal popup becomes empty on button click. I am getting empty string on code behind. Is there any solution to fix this?
which modal is that?
if this is an fancyBox modal u should use this one the configuration of the fancybox:
parent: "form:first"
Okay,
I have this scenario:
There is a user control with an update panel within it. There is a button within that update panel with proper postback trigger being set. The button_click event is also defined well. I need to call a full postback of the parent aspx page once the "button_click" event is completed. Under ideal case, all the form submission events such as postbacks occur before event based methods are executed. This means my page will first be reloaded then the button click event will be executed. I want something like to reverse this operation. First Button_click event execution then one postback after that on the aspx page(this page calls the user control-> and this user control has the updatepanel with button in it).
Any possible way out would be highly appreciated.
I don't think there's a way to change ASP.NET's lifecycle, like the one you described. A (dirty) way of postbacking the parent page is however to put a hidden button on that page, and call it via javascript in the UC. (via ScriptManager.RegisterStartupScript)
If user don't checked, I want to show asp:ModalPopupExtender and get numeric value from this form.
I'm using asp.net wizard control. I don't know "finish" button id. Can somebody help me?
You should set the target of the ModalPopupExtender as a dummy control, i.e., a hidden Button, LinkButton,... that never is going to be clicked by the user.
The Wizard control have a method called FinishButtonClick. Here is where you have to check the state of the CheckBox and show or not the popup calling to the method Show() of the ModalPopupExtender. You also can call to the Click() method of the hidden control or do it with JavaScript usign the BehaviourID of the ModalPopupExtender. Your choice.
Cheers!
To get "Finish" button id, just open the page in browser & view the rendered html code (Right Click -> View Source). From their you can get the finish button id.
And after getting "Finish" button id, you can easily associate a Client-Side event to do the required job.
I have a made panel with ajax modal popup which opens on a simple button.But i want to open popup with data grid default edit button or select button
Have a look at this ModalPopup Demonstration, http://www.asp.net/web-forms/overview/ajax-control-toolkit/modalpopup/launching-a-modal-popup-window-from-server-code-cs
You will have a better understanding how the modal popup works.
I have an aspx.cs page with the following code:
hypPopup.Attributes.Add("onclick",
"window.open('Popup.aspx',
'',
'height=650,
width=800,
location=no,
toolbar=no,
status=no,
scrollbars=yes,
resizable=yes');
return false"
);
When I click the hypPopup link, the window pops up which is fine, but if I close it and refresh the page, the popup keeps popping up. I have to leave the page and come back for it to stop popping up on every refresh. Is this behavior by default or is there a fix to it?
hypPopup.Attributes.Add is done in the Page_Load
If the hypPopup button is set to run on the server, try removing that. Maybe its causing a repost and something int hat repost triggers the button click, so when you refresh the page its resimulating the repost and the click?
I don't know... just trying to think of something!
I have tested this using both <asp:Hyperlink> and <asp:LinkButton> on both Firefox 3.0.6 and IE 6, neither of which reproduce this sort of behavior. The popup window will not appear if I refresh the page (which is in fact the desired behavior since client-side events should only be fired by specific client-side actions.)
What browser are you using? Is that the exact code being fired, or is there more to it then what is displayed?
