display confirm message box for action

[Grey]

how to design confirm message box, like Javascript Confirm box, in ASP.NET??
if the user click "YES" in the confirm box, i need to do something, else do
other things. Do I need to have javascript confirm box or ASP.NET has such
feature??


Million thanks.

For client-side user interaction, use JavaScript.

for example:
create a button: button1
Page_Load():
this.Button1.Attributes.Add("onclick","javascript:if(confirm('No to
cancel?')== false) return false;");

if "Cancel" button pressed, this page will not post back.

Just to add to this.

You can ONLY cancel the post back with javascript like this, you cannot
branch and "do other things".

for example:
create a button: button1
Page_Load():
this.Button1.Attributes.Add("onclick","javascript:if(confirm('No to
cancel?')== false) return false;");

if "Cancel" button pressed, this page will not post back.

Just a note: don't change the javascript to the seemingly identical but shorter
return confirm('No to cancel?')
because .Net can add it's own javascript to that onclick handler. This shorter
version would prevent the execution of that code! This is also why you *need*
the closing ";" to separate your code from the additional code.

By the way, you don't need to specify "javascript:" for an onclick handler.

I've never seen that recomendation before. Is it related to the classic
"validator ate my onclick event" problem?

one example of problem:

Is it possible to have button text as Yes/No instead of OK/Cancel ??

AFAIK, not with a javascript confirm. Maybe using vbscript msgbox...?
