Hiii Alll

I need to display a message to the user after clicking the button control. How to do this in c#.net? I could not find Msgbox() option as we hav in vb.net.

can any one help me

Hi.
If I do so Am gettin this error
Error The name 'MessageBox' does not exist in the current context
Do we hav to create a separate function or to use any namespace for this.

I guess the Call is done within a Form?
The MessageBox is included in the namespace System.Windows.Forms
Do you have this in your using at the top?
Or have you tried to write

System.Windows.Forms.MessageBox.Show("This is a message");

MessageBox is only available in Window Applicaitons. In ASP.NET, you cannot use the MessageBox class or MsgBox function like you can in a Window Applicaitons, but you can emulate this functionality by streaming out a javascript alert instruction like this:

Response.Write(@"<script language='javascript'>alert('This is my Message')</script>");

In ASP.NET with code Behind VB I have used msgbox().
It worked well.
But in C# :( am gettin into trouble

Okai..
This is my sample code for Palindrome checking.
Got a string in textbox 1.

TextBox2.Text = StrReverse(TextBox1.Text)
            If TextBox1.Text = TextBox2.Text Then
                MsgBox("String is palindrome", MsgBoxStyle.OkOnly)
            Else
                MsgBox("Not a palindrome", MsgBoxStyle.OkOnly)
            End If

This code is done in Asp.Net webapplication with VB code behind.
Can u say how to use message box with C# code behind:?:

So this is a Web application in c#.net
Well then you cannot use the Messagebox. This function / method
is used within an windows application
As mention earlier , you can solve this by using Javascript or ms.Ajax (Popup /modalpopup)

Hmmm Fine....
In C# we have to use script for messageBox.Okay let me do.
Tnx...

Select the function name "MsgBox", right click and from the menu select Go to Defenition and post the fuction defenition here. I suppose its a user defined function

Hi again

I yust wonder who this could be done..
Do as i told over.. in button click method

System.Windows.Forms.MessageBox.Show("This is a message");

then select: project -> add reference
Then scroll down to System.Windows.Forms and select this.
Press ok

Hi,

I dont think what Frank is saying will work when deployed (But i will gladly be proven wrong as i would like to be able to use the messagebox functionality in an asp.net app). The messagebox will throw an exception because you can not show a modal form on a clients machine when it is created server side. The only real option avaliable is to Use javascript or Ajax as someone has mentioned earlier in this thread.

Page.ClientScript.RegisterClientScriptBlock(typeof(Page), "SCRIPT", string.Format("alert('Hello World')"), true);

This is the only solution that works within this post:
Page.ClientScript.RegisterClientScriptBlock(typeof(Page), "SCRIPT", string.Format("alert('Hello World')"), true);
