How to show MessageBox on asp.net?

Question

if I need to show a MessageBox on my ASP.NET WebForm, how to do it?

I try: Messagebox.show(\"dd\");

But it\'s not working.

Answer 1

It's true that Messagebox.show("dd"); is not a part of using System.Web;,

I felt the same situation for most of time. If you want to do this then do the following steps.

• Right click on project in solution explorer

• go for add reference, then choose .NET tab

• And select, System.windows.forms (press 's' to find quickly)

u can get the namespace, now u can use Messagebox.show("dd");

But I recommend to go with javascript alert for this.
