How do I create a Messagebox in ASP.NET web forms?
I can't add system.windows.form.
Please help. I don't want to do it in javascript.
To pop-up a message box you use alert() in JavaScript. You have to use JavaScript to do this.
You can use a ModalPopup from the ASP.NET AJAX control toolkit.
Of course, behind the scenes, it uses JavaScript, but you don't have to write the JavaScript yourself.
in web you have 2 chooices:
create a div and show / hide it with the message
use the alert or confirmation box with javascript
if you're using ASP.NET, and you want this kinda of things out-of-the-box I strongly suggest you to download and use the ASP.NET Toolkit
you will see many solutions in the left side that you can use in your project and one of them is the Modal Popup ... check them out!

I would like to display another web page within a web page... maybe using framnes, then be able to simulate mouse clicks/keyboard input randomally on this new page that is within my page.
Is this possible using asp.net/ javascript or any language. asp.net preferred
Thanks for any input
I dont think it is possible on client. If you are creating a desktop application then may be it could have been done like in automation, but on clint side even javascript cant create events like mouse clicks, it can only handle such events. however you can insert text in text boxes by traversing and accessing DOM in your javascript.
Its Definitely not possible from Server side in ASP.Net
I am making an ASP.NET application. I have a page which displays a list of data [as a GridView].
I need to display a list of objects [as a GridView] in a new view over the current view, not a new window but a kind of AJAX popup, so that the context shiftes on the page to the new view/form!!
Shall i use Modal Window for this? If so, how shall I do it, as the function to open the modal shall be fired when an item of the GridView is selected?
Is there any plugin which can simplify my task?
You could always try the ASP.net Ajax Control Toolkit
http://www.asp.net/ajax/ajaxcontroltoolkit/samples/modalpopup/modalpopup.aspx
It supported by the ASP.net team and it's really easy to use!
There is a good plugin called blockUI for jQuery that will let you achieve this quite easily.
You can use it to show any HTML that you desire or even load an iFrame using that. You can download this plugin and find examples here
http://jquery.malsup.com/block/
If you post some sample code I can probably help you create your modal pop up!
Please do vote up my answer or mark the checkbox next to it, if I helped you at all. Thanks :)
I have tried in my MVC app to add jquery modal dialogs to prompt the user for input, but my code turned really sloppy just prompting the user for 1 field of information.
SharePoint 2010 has ajax overlays that are very functional, some even include the office ribbon.
How is this being done? What libraries can I use where I can open up entire forms as ajax overlays on top of a page?
Thanks so much!
If you want to show complete forms, use http://plugins.jquery.com/project/jquery-framedialog - I haven't tried it with standard SharePoint forms, but it should work if you set the return url to a page that will close the dialog.
If you just need a nicer looking javascript prompt, use the standard jQuery UI dialog and define the html for the form where you are using it.
With MVC you may find it easiest to post the form using ajax (there is a jquery method to serialize a form, though I don't recall the exact syntax) rather than posting the iframe - that gets you a callback structure that is a bit easier to work with if you are doing more complex stuff with the dialogs.
What I am trying to do is create a bit of reusable code that can write a modal popup, either through javascript or using the ajaxcontrol toolkit all from the code behind.
The modal would be a sort of login pop up for controlling access to more restricted areas of the website allowing certain users to re-credential in for higher access.
I was thinking of doing a user control but I forsee some problems with passing all of the appropriate information along without it being completely hoaky.
If anyone has any good links or advice for doing so it would be greatly appreciated!
Thanks!
EDIT: I know how to use the ajax control toolkit and its controls, and I know how to make login screens, I'm asking how to do this entirely from the code behind from a class that would be independent of its implementation
Write a server control or an asp.net extender control like ajax control toolkit does.
The best you can do is download the source of AjaxControlToolkit from CodePlex and explore the source of ModalPopup within that.
Another thing you can do is just simply call the popupExtender to show from the code behind file.
As we know the extender has to be somehow linked to a target control, just add a dummy control as a hidden textbox (actually to hide the control, do it from the asp file, as style="display:none" not from the control properties (visible=false) otherwise it won't work), and then just call from the code behind the extender like this:
DummyTextBox_ModalPopupExtender.Show();
You can call it in the page_load or with anyother trigger.
No need javascript neither client side, just, server side.
Xds.
There's a sample modal popup using the ajaxtoolkit on asp.net
The modalpopupextender in the Ajax control toolkit is easy to use, plus it has a server or client side method for showing the popup (in past versions, I had trouble with the server-side method, but it may have been resolved in the current version).
You could put the modalpopupextender inside the master page, and create a JS method in the master page you can call to invoke the modal popup extender, like:
function showPopup() {
var modal = $find("<%= mpe1.ClientID %>");
modal.show();
}
The contents of the popup can be replaced via javascript, as you control that content.
Add BehaviorID="my_cool_id" to your modalpopup extender and add this to any server function
ScriptManager.RegisterStartupScript(Page, this.GetType(),"id","function pageLoad(){$find('my_cool_id').show();}",true);
I would like to create a javascript modal pop up window to get some values from a user in a ASP.Net 2.0 webpage.
The basic idea is this. When a user clicks a button, a modal window will come up and ask 3 or 4 questions. The asp.net page will not be able to be changed while this window is up. Once the questions have been answered I need to grab the values from this window so the asp.net page has access to them and can handle them in the code behind.
Can I please get some examples on how you would implement this scenario.
Have you looked at the ModalPopupExtender?
http://www.asp.net/ajax/ajaxcontroltoolkit/samples/modalpopup/modalpopup.aspx
The easiest methods would be to either use ModalPopupExtender as mentioned by Jon or potentially use jQuery's thickbox or something similar as well.
Otherwise, you could roll your own JS to do it.
You could use the javascript function 'window.showModalDialog', but it only works in Internet Explorer.
You can pass in and return any number of variables by wrapping them up into an object.
