How to popup a msgbox from asp.net code-behind?

[Guest]

I am writing a web application using asp.net(vb.net). And, I have an asp:
button in the web form, I would like to prompt some message to user, when the
user click on the asp:button. How to I do such? Because I notice that, I
can't use msgbox as writing window application.

Thanks....and have a nice day.

You can fill javascript in the code-behind file 2 ways:

1. just use Response.Write("<script
language='javascript'>alert('aa');</script>");

2. RegisterStartupScript or RegisterClientScriptBlock
RegisterStartupScript will reponse a javascript block to client so that the
client will execute the script once the page was loaded completed.
RegisterClientScriptBlock is usually used for a function or somethig.
