Modal Loading Popup On Async Postback?

Sep 9, 2010

I have a web application that does some complicated data retrieval tasks and so I am trying to show a modal dialog box with a loading message when the tasks begins. I am using ASP.Net 3.5, the jQeury popup I am using is bPopup.

Firstly, I have a table where the rows can be clicked. Im am using a script from[URL] to do an async postback from the table row. Here is my function

[Code]....

so the $("#<%=lDiv.ClientID %>").openPopup(); opens up my loading modal and then the server starts doing its thing. When the server finishes though how would I then close the dialog box?

I just need to call one line of code like $("#<%=lDiv.ClientID %>").closePopup();

AJAX :: Modal Popup Using Modal Disappear In Postback

Jan 24, 2013

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?

AJAX :: Modal PopUp's OkClick Causing Full Page Postback?

Apr 28, 2010

I am having issue with my ModalPopUpExtender's OKControlID. I have a button inside an update panel that should do AsyncPostBack. The button works fine and runs server side code but it causes full page postback. How do I solve this issue? I want the 'OK' button inside the modalpopup to call the serverside code and update Label control 'label3' without causing the page flash. Given below is my code;

MarkUp:

<html xmlns="http://www.w3.org/1999/xhtml" >
<head id="Head1" runat="server">
<title>Next Gen Web Browser</title>
<script src="http://ajax.microsoft.com/ajax/jquery/jquery-1.3.2.js" type="text/javascript"></script>

AJAX :: Modal Popup Close After Postback Event In An Ascx File (user Control)?

Feb 15, 2011

I have an aspx page with multiple modal popups. These modal popups are trigger in the page behind code using .Show() and .Hide().

This is what I have in the .aspx page for the particular modal popup under discussion:

[Code]....

The example below demonstrates the type of calls I am making to the modal popup extenders. Basically using the Datalist item command, the datalist commands are responsible for triggering my modal popups.

[Code]....

They all work fine after postbacks except the "activityReport" case (the last one). The only difference with this modal popup is that it contains a user control and all the postbacks are happening in the user control. So the problem is that in the last case whenever a postback happens in the user control then the modal popup is close.

1. If I separate the modal popup and place it in a page all by itself and trigger it to .Show() through a button click in the page behind code then the modal popup doesn't close. See below example.

[Code]....

2. The button click event in the test page looks as follow:

Dim iCounter as Integer
Dim iQuantity as Integer = 10
Protected Sub btnFoo_Click Handles btnFoo Yadda
For i as Integer = iCounter to iQuantity - 1
//do something with AsyncPostBackTrigger until iCounter = iQuantity - 1

I am new to the concept and feel like there must be something really easy that I am missing.

C# - 'Loading' Web Page For Async Call?

May 13, 2010

I have a simple web page in ASP.NET / C#. Currently to fully render the data I require calling a block of code that runs on background threads and can take multiple minutes to complete. I've got it to the point (using the async attribute on the page declaration) to execute and return fine with the html once it's done. What I'd like it to do is allow me to return immediately with a 'loading page' of some sort and then have that page be updated when the background work has been completed. Right now I get nothing on the page while the background work is being processed.

AJAX :: Async Loading Of Measurements Into An Array And Visualize Them To A Chart?

Dec 13, 2010

I have to code a chart which get his data of a PLC-control. The problem is that the PLC send every second a measurement to my program, so I have to refresh the chart every second. Via a timer-element of AJAX I can load the chart every second with new data, but I don´t know how I can make this asynchronous.

I want to have this:

The chart-Website should refresh the chart every second via the ajax-timer. The measurements which were used should stand in an array which is updated with the PLC-control-Function.

BUT I DON´T KNOW HOW I CAN DO THIS!!!

AJAX :: Async Loading Of List - Similar To Facebook And Twitter?

I tried to search around, but could not find anything for this question which must be wrong, because I would guess there were a lot of topics about it.

Anyway, I would like to load lists on my site in a similar style to Facebook and Twitter, where initially x records are loaded into the list, and then after the page has loaded the list expands downwards with more rows of content, or add a "more" button in the end. I am using ASP.NET with C#.

AJAX :: Modal User Control On Top Of A Modal Popup + Javascript Causes Page Flash

Jul 29, 2010

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++;
}
}............

AJAX :: Modal Popup Click Control Within Panel Is Closing Popup

Jul 27, 2010

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.

AJAX :: Modal Popup Moving Data From Popup To Parent

AJAX :: Get One Modal Popup To Trigger A Second Modal?

Aug 19, 2010

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
