How to implement javascript on button, C#?

Hi,

I would like to implement a javascipt prompting user when they click on the button. For e.g. "Do you really want to enter?"

Thanks.

Is this on a Web Application or a Windows Forms Application ¿

Web application

You've should have posted this question in the ASP.NET forum.

Anyway, the answer

Code:

---

<asp:Button ID="Button1" runat="server" OnClientClick="return confirm('Do you really want to enter?');" Text="Button" />
