How are you opening window form?

footballpardeep 25-Nov-13 13:41pm

Form f=new Form();
f.show();

Why you sre using windows form in web? Any particular reason.

This won't work in the web. C# code executes on the server generating HTML which is sent to the client.

I have developed a customized confirm box. whoes yes/no result we can take on server.

First of all, why? "Opening a window's Form from and asp.net webpage" is already a great fallacy. What are you using, ActiveX? Or do it only locally? Sounds like a technology abuse.

I am using System.Windows.Form.

At server (C# code) if i prompt a conform box(javascript). At server we can't idenify user clicked yes or no. Sp for i that i created confirm box window inheriting Form class.

Wait, wait... Do you show Windows Forms application on server side. How would see an operate it. A cleaning person working between those countless racks with blade host computers?.. :-)

Thanks for the link, but can i get user response from those confirm boxes at server ?

Sergey Alexandrovich Kryukov 25-Nov-13 14:23pm

I have a strong feeling that you don't clear understand what happens on the server side and what on client side and, hence, how Web works. Sorry if I'm wrong here. But anyway, I cannot catch any of your explanations...

Let me try to explain what i want.

Suppose user want to save some data to database , before that i want to do some confirmation. so code of btnSave_Click will be somethink like this.

if(myconfirmBox.Show()=="Yes")
{ //Then this code
}
else
{ // Otherwise this code
}

I have lot's of such confirmations in c# codes

In other words. I tried to design a window similar to like we have MessageBox.show() in window form application, which return DialogResult after user response.

Sergey Alexandrovich Kryukov 25-Nov-13 16:10pm

How is that related to a Web application?

I know its hard to swallow, but your approach is totally incorrect (been there, done that). You must not mix Windows Forms with ASP.Net. Please consider the answer provided and try to learn some more javascript.

It is a bad practice to mix Windows Forms and ASP.Net. They don't work alike and nowdays there are ways to program Web Pages to make them behave almost entirely or even better than a Windows Form (HTML5, jQuery, AJAX, or even with plugins sucha as JavaFX, Flash and Silverlight).

A confirmation can be fetched with a simple javascript "confirm". It works like a Yes/No MessageBox:

XML

<asp:button id="btnConfirm" runat="server" onclientclick="return confirm('Confirm action?');" onclick="btnConfirm_Click" />

The button configuration above will first throw a confirm box, and catch the response on c# or VB for the method btnConfirm_Click which you need to have in advance.

Your current aproach will display erratic behavior such as what you're getting, and will be incompatible with all non-Windows devices (Apple, Android, etc.).
