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.

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

Anyway, the answer

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