Disabling button control event.

[peli]

Hi,,

I want to disable a button control event after first clicked.
The reason is that when the button is clicked, a dataset which holds data
accesses database to save data.
If button is clicked twice, the same data is stored twice. Therefore I want
to disable the button immediately after a client clicked.

Does anyone know about this?
Would you teach me?

Thanks.

hi peliz, there is no automatic way to achieve what you want. You could use
various workarounds, but the easiest way around this would be to use this
free web server control provided by andy smith.

In your save button click event, add the following code:
yourButton.enabled=false

This is excellent.
Thank you very much

YOu cant disable the button like that.
Peliz, maybe i should have said this earlier but if you dont plan to use
that custom control then you might just want to wrap your code within an if
block checking against a session variable or viewstate on whether it is
already set and if false to execute the code and set the viewstate this way
subsequent clicks will fail
like :
if (ViewState("FirstRound") is nothing) then
'execute code and insert/update/delete from db
'after successfull execution set the viewstate
viewstate("FirstRound") = "OK"
else
'code already been executed so do something else or do nothing at all
response.redirect("nextpage.aspx")
End if

or place the logic in your stored proc, that is check to see if the record
has already been added/deleted/updated and if so do nothing, this should be
fairly easy to achieve

The stuff with the viewstate I havent really tested, its off the top of my
head but makes sense so give it a shot
