What is the JOptionPane input equivalent for C# WebForm

Question

0.00/5 (No votes)

See more:

I've used java only in the past and I'm still getting used to C# so I need to know if it's possible to ask for and accept user input by means of a JoptionPane equivalent.
Bear in mind, I'm working with a WebForm and not a normal Form

I've used ScriptManager.RegisterStartupScript before to display a message but this time I need to also accept input.

All help is appreciated.

A dialog? I'd suggest learning jQuery and then use Jquery UI dialog.

Is there no built in method?
If there isn't I could always call up a WebForm and get it to do it but I'd much rather use a built in method.

Built in dialog? The input() javascript function but I don't think anyone uses it because it's ugly.

Member 11956930 3-Sep-15 13:52pm

Is there any documentation I could use to try that out?

Sorry, it's actually prompt(). http://www.w3schools.com/jsref/met_win_prompt.asp

This doesn't work for me (I'm using C# in Visual Studio)
I'm not too used to C# and I have no idea what 'var' is

C# is the code that runs on your server and it will generate html that is sent to the client. To create a popup on the client, you need JavaScript.

Well this is far more complicated than I expected.
I don't supposed you can point me in the right direction for that.
Also, the program needs to be submitted and run on another computer. Wont that computer require JavaScript as well, or is it just a built-in library

Yes, web development is complicated because of the disconnect between client and server.

You could make a windows forms app instead or a console app.

Javascript should come with every major browser. The other computer will also need IIS to be able to run the webpages. Why are you doing a web app if it will be run on a single computer?

Unfortunately, my lecturer believes that we should start with WebForms and then move on to Windows Forms.

Maybe you attend wrong school. I would never do such things. Anyway, your question and comments suggest that you don't quite understand the Web model ("built-in method" and so on). Please see my answer, but perhaps you should start with learning the basics.

It can be nearly anything. First of all, it's not a good idea to directly transfer the UI ideas from Swing to WebForms, where the basics of technology are very different. By this reason, there is no exact "input equivalent", and cannot be. What to do practically, depends on what exactly you want to achieve. Similarity to JOptionPane cannot be a real goal. The real goal should be formulated in semantically sensitive form.

First of all JOptionPane is used to pop-up some dialog. It's a bad idea to pop-up a web page. Such action is intrusive, inconvenient for the users, and will be blocked by many through some browser plug-in. At the same time, if you really need some modal behavior, you can mimic it on the same page, which should work perfectly fine. One way to do it is the jQuery UI dialog plug-in: https://jqueryui.com/dialog[^].

Also, you can find many 3rd-party jQuery plugin collectively known as "modal popup", featuring different visual effects and styles, such as transitions, and, notably, dimming of the rest of the page. Please see:
http://bfy.tw/AJH[^].

If you need to learn jQuery (highly recommended), please see:
http://en.wikipedia.org/wiki/JQuery,
http://jquery.com,
http://learn.jquery.com,
http://learn.jquery.com/using-jquery-core,
http://learn.jquery.com/about-jquery/how-jquery-works (start from here).

But, more importantly, re-thing the whole idea. Do you really need to input data in a modal manner, to give a modal request to a user? How about a way more powerful model where the user can edit some changes in data at any moment of time? It may need more work, but can provide a lot more usability. The area for entering the parameters can be something line a "div", or some extender control (http://bfy.tw/1ccA[^]).

As I say, it can be nearly anything.
