What is the equivalent code of MessageBox in ASP.Net? Can anybody help me identify the code in ASP.Net that is equivalent to MessageBox (C#) or Alert (JSCript). I need a message box that will pop up when a certain condition is not fulfilled.
Your response is highly appreciated.

C#:
MessageBox.Show("Your Message Here")StringBuilder str = new StringBuilder();
str.Append("<script language='javascript'>");
str.Append("alert('Your Message')");
str.Append("</script>");
RegisterStartupService("Msg",str.toString()); •

I tried the given code but I receive a message such as StringBuilder not found. Does it need an assembly or header file? What is it?

compiler cant found stringbuilder class since you didnt register the namespace. you can use the class' fully qualified name or you can use the using statement at the top of your code file like :
System.Text.StringBuilder s = new System.Text.StringBuilder();
or include the using statement above your class definition :
using System.Text;
then you wont get any compiler errors.
System.Text.StringBuilder s = new System.Text.StringBuilder();
or include the using statement above your class definition :
using System.Text;
then you wont get any compiler errors.

the easiest way to show a message box is this :
<asp:button id="foo" runat="server" text="foo" onclientclick="alert('message box is shown now')" />
i can help you with the details if you be more specific on what you want?
<asp:button id="foo" runat="server" text="foo" onclientclick="alert('message box is shown now')" />

hi
as per my knowledge the best way for getting message box in asp.net project is creating a class and put there, following code.
'To display the message
Public Sub msgbox(ByVal msg As String, ByVal mypage As Page)
mypage.RegisterStartupScript("msg", "<script>alert('" & msg & "');</script>")
End Sub
then you can use this using object of this class any where in your project.
try this.
Best Luck.

Thanks. I experience some problems again. What if let's say a user had entered an invalid value in a textbox, then a MessageBox should pop up like "Sorry, minors not allowed!". How can I do this?

{
var text = document.getElementById('<%= Textbox1.ClientID %>').value;
var retVal = false;
//forexamle let say you wont allow text longer than 10 characters
if(text.length > 10)
{
alert("the text entered is not valid");
retVal = false;
}
else
{
retVal = true;
}
return retVal;
}
</script>
<asp:button runat="server" id="button1" value="validate" onclientclick="return doValidation()" />
