is there a way to create a pop-up window in a VB.Net application, specifically when a button has been clicked?
I'm designing a little help section on a web application I'm working on, and I wanted to have a variety of written steps followed by some sort of "Click here for an example" button that brings up a new window (not a new page, just a new window). The window would simply contain an image control displaying a picture that describes the written steps.
The best example I can come up with is here on Amazon when ordering a clothing item such as a pair of shoes. When the user clicks the "Sizing Info" link button, a pop-up window appears with information to help you order the correct size.
So is there a way to create a pop up like that in VB.Net?
In vb.net not, websites are handled differently. For displaying a popup using asp.net you need a client-side language, like javascript.
For instance this nice jquery script http://jqueryui.com/dialog/
Your vb.net can't open dialogs on client-side. If you need to get/send some information from the server, simply use webservices to send/fetch the information using ajax.

I have a C# web app that pulls a json object from a web service after a button click even. This object has HTML code saved in one of its properties. I need to popup a window to the user from this server side event that displays this HTML.
The event could also return a list of objects so I would need the ability to display the popups one after the other.
What is the best way this handle this issue?
I found the answer I was lookinf for here

I need to implement some, let's call it "dialog" in some old ASP.NET project that I took over. It's huge project so I'm not allowed to implement new things.
I have a form on which user can attach up to 3 file attachments, enter some 10-15 fields, and when required fields are filled, submit button get's enabled.
What need to be done is press submit, wait for any possible response for server, and then display some sort of dialog, alert, lightbox which would display short summary and list of correctly uploaded files.
What would be the best approach to do this in ASP.NET?
Considering jQuery Lightbox is designed for overlaying images rather than HTML I would recommend using FancyBox or FaceBox instead.
I have been given a requirement to take an existing stand-alone web-form (i.e. uses postbacks) and throw it into a lightbox.
The standalone web-form already has save and cancel buttons that have predefined behaviors. For example, the Save button attempts to save the form, and either displays validation errors, or if the operation was successful, redirects to some other page in the app.
However, in the context of this new "lightbox mode", the Save button should additionally close the lightbox if the operation was successful.
I see two options:
Option 1-->UpdatePanel + ModalDialogExtender:
a. Extract a UserControl out of the standalone web-form that includes everything but save/cancel buttons
b. Introduce Save and Cancel EventHandlers on said UserControl
c. Use this UserControl on both the standalone and lightbox versions of the page, and wire up the events appropriately
Option 2-->Client side lightbox (i.e. jQuery)
a. ....
I'm a big fan of jQuery and tend to favor its use for Ajax functionality b/c of the level of control it gives me. On the other had, I also want the simplest solution that will possibly work. Assuming that option 2 is that option, any guidance on how to proceed would be appreciated.
I am using fancybox (see http://fancybox.net/home) with great success. It has a mode where it can show my aspx page (usually an edit form without menus and so on) in an iframe fancybox.
It can also be closed from javascript in the iframe.
I am building a Web Application using asp.net (C#). I come from windows forms development and find myself in a hard spot. Im making an application where the user should edit some simple information about himself, and thus i need to create a new dialog. How do I do that in asp.net? I have a button which event is handled serverside, and when i click lthis button i want to popup a dialog where i can show my custom web control (or any web control, lets make it generic from the start). How do I go about with doing so?
I got some part of the way by looking at the internet, that i need to make a section and set the z-index to 1000, but how do i make it visible (block)? Please help here as i am completely lost...

If you're not concerned about using a library, try Microsoft ASP.NET AJAX Control Toolkit, they have several controls that can create something you want (the ModalPopup control).
The AJAX Control Toolkit has a ConfirmButton extender which will do exactly what you are looking for.
I used to do the following:
1. my new pop up is just a new aspx page like any other page
2. add a button (or just a link) that fires a client side java script function
3. in the function I use window.open and put params to open my popup page with no toolbars or scrollbars and proper size to its content

I am writing an ASP.NET 3.5 web app that displays a list of items. I want to be able to display a non-modal popup with details when the user selects an item. I want to be able to display several detail popups simultaneously. (i.e., the user can click an item to see its details, then click another item to get another popup.) Currently I call RegisterStartupScript during postback to write a "window.open(...)" script to the page when it re-renders. The problem, of course, is that this requires a full page postback and refresh.
It occured to me that this might be a perfect use for XMLHttpRequest or AJAX but I don't know how to do it (or whether it's even possible or smart to do this). Can someone show me the way?
I have the AJAX Extensions installed but I'd prefer not to use the AJAX Control Toolkit.
EDIT:
Some clarification: When the user selects an item a custom event is raised. On the server I handle this event and use some server-side logic to construct a URL which I then use with RegisterStartupScript to construct a "window.open(myUrl...)" script. But posting back the whole page to do this seems inefficient and I'd like to know if I can just make a call to a simple server-side function that constructs the url and sends it back without having to roundtrip the entire page.
Creating a popup has very little to do with AJAX, and a lot more to do with JavaScript. See the jQuery dialog library here. You can then use jQuery's AJAX API to do your server dirty work :)

You can use DHTML Window widget.
It offers many way to display either modal or non modal window.
Also it supports AJAX.
You can use dhtmlwindow for open a new window, or
dhtmlmodal to open a new modal window.
Of course, you can edit it to match your requirement.
Sample:
var insWindow = dhtmlmodal.open("insbox", "iframe","UserMaster.aspx?" + queryStr, "User Master", "width=425px,height=500,center=1,resize=0,scrolling=1", "recal");
Do you really need to open a new window? Opening an absolutely positioned DIV or a new layer on top of the current page in the same window is all the rage these days.
Edit:
I don't think it would limit the number of popups, there is some neat stuff that can be done these days with libraries like jQuery + jQuery UI, you can simply create as many of these DIVs/layers as you need and make them movable, resizable, etc. Only thing that real popups have and these do not is that they do not appear on the tab panel/taskbar.
Yes, you will be limited to the size of the window in which is the main page opened, however, I don't personally see it as a problem since most people surf in a maximized browser window anyways.
Implementation of the oldschool typical popup window is undoubtedly much easier for you, but it also runs into problems with end user popup blockers. Just had that problem # my work, they needed to make a popup during the certificate authentication process for some reason and as soon as Yahoo released a new version their toolbar, it quit working).
