AJAX :: Modal Popup Does Not Work With ScriptManager.RegisterStartupScript
Sep 20, 2010
I am using a masterpage that contains a javascript script (does not matter what it does) and on each page under that masterpage I am registering that script to run on page load. On the page under the masterpage, I am calling a modalpopupextender to display on a button click. Now, if I disable the register startupscript, the popup extender works fine, if I register the startup up script it does not
here is the script regster call
ScriptManager.RegisterStartupScript(Me, Me.GetType(), "addscript", "miscscript()", True)
I have also tried this
Page.ClientScript.RegisterStartupScript(Me.GetType(), "addScript", "miscscript()", True)
I had this working fine using the second example when using .net 4 and the Ajax toolkit for 4 but I am now having to rollback to 3.5 due to a vendor requirement.
Here is a little bit of extra info:
If I put the script in page and not in the masterpage and just run with a window.onload, both work fine, which is why I have figured that it must be something that I am doing with the registration of the script.
When I say it does not matter what I put as the sript, I mean, it can be a complex element property adjustment or a simple alert, nothing seems to work.
I have this script in the masterpage because the script is used on everypage of the website.
I am also using the modalpopextender.show() on button click instead of using the element that it is attached to being the launching element.

I am using a third party UI Library (devexpress) to implement some data grids. These grids work with Callbacks (not UpdatePanel partial Postbacks).
I am trying to use Scriptmanager RegisterStartupScript to execute some code on the client after the callback. This works great with partial postbacks but does not work with Callbacks.
Is there any way to queue client side code for execution inside the callback server side handler?

I want to alert some message on the click of a Button which is inside the Update Panel. Therefore I used "scriptmanager.registerstartupscript" but after using this I found that my event started responding slowly. Can anyone please help me in finding an alternative of "scriptmanager.registerstartupscript".The point that needs to be noted is that the button is in an Update Panel. And its my cenessity to find some alternative of it.

I have a user control that needs a javascript function so I put my JS code in a variable and used the ScriptManager.RegisterStartupScript in Page_PreRender of the control as follows
StringBuilder jscode = new StringBuilder();
jscode.Append(@"<script language=javascript>");
jscode.AppendLine(@"function MyFunc(x) { {alert('hi'); }");
jscode.AppendLine(@"</script>");

Anyone know why RegisterStartupScript won't work in the UploadedComplete event? It used to work just fine, but in version 40412, it doesn't do anything.
I had started another thread called 'AsyncFileUpload Broken??!!??', before I realised what was causing the problem. Now that I have found the culprit, I thought a new thread is needed on this issue alone.

I am trying to get the modalPopup to work. Don't get any errors, the panel popsup as is supposed to, but the background doesn't gray out and the background of the panel doesn't display correctly either (it is black). The background of the main page doesn't change. To make sure I wasn't doing something wrong, I downloaded the samplcode (vb) from the AJAX website, and created a completely new web page, css file, .vb file, etc. Still have the same issue. I am using the latest version of ajaxcontroltookit ( 4.1.40412.0), VS 2010 RC, and VB)

Modal Popup user control (its a message box) on top of a modal popup with javascript that maintains postback on a scrollable div all inside of an update panel causes my page to flash on postback of the user control. If any one of the peices (user control, modal popup, javascript) are missing everything works fine. The javascript is maintaing scrollback on a scrollable listview on the page. A modalpopup is shown on top of this main page that is for report parameters. The user control is used for validation and is displayed if a parameter is invalid. I know this may not be the best design, but it can't really change unless its a minor change. Heres the js if anyone wants to see popup or styles let me know.
//Begin methods to maintain or reset scroll position during postback.
var controlIds = [];
var scrollTops = [];
//Register a control to maintain its scroll position on postbacks.
function MaintainPostback(controlId) {
controlIds.push(controlId);
}
//Find the div/control id in the controlIds array and set its scroll position to 0.
function ResetControlScrollTop(controlId) {
var index = 0;
while (index < controlIds.length) {
if (controlId == controlIds[index]) {
scrollTops[index] = 0;
return;
}
index++;
}
}............

I look for a good way for arrangement Admin pages Items
for example Admin Upload Page consists of these sections:
* make a new folder
* delete folder
* upload file in folder
* show folders information (in a gridview)
* download test
so I think one way is showing this sections in modal
but when I tried make a new folder in modal after clicking in create folder button modal disappeared.
Is there any way that modal doesnt disappear until user click close button?
I mean I want modal to behave like a page.
If there isn't a way what to do for classification sections?

I'm using modal popup extender and panel with calendar in it. Click the "Next / Previous Month" closes the modal popup. How do I tell the modal popup to ignore click events in a calendar control inside the panel targeted for popup? I'm confused because when using extender before, you had to click OkButton or Cancel to close popup. I have update panel for reason. I just minimized the code for easy review.

I have one page with a panel that makes up my ModalPopup. On the ModalPopup there is an updatepanel with a textbox and a button in it. There is a textbox on the "parent" page and I want to click the button on the modalpopup and move the data from the popup textbox to the parent textbox. So far, no joy. I have a line in the code behind to move the data between textboxes and I have also tried javascript to do the same thing but I am not able to make this happen unless i click the button twice.

How can I get one modal popup to trigger a second modal? And in between each modal, I need to execute server code.
Page load, check if question needs answering -> Modal 1 -> User answers -> run server code to check if question two needs answering -> Modal 2 -> show page.
I could do this using a series of asp:Views if there is not a clean way, the management just really likes the modals

I can't use RegisterStartupScript('window.open...) because then Google Chrome silently blocks the popup window. I can't use javascript onclientclick in the markup, since I have to open the popup window after running some code in the button click event handler.
