Disabling a button but calling its server code

[Paul]

Hi

I am trying to create an "Update" button for my form.

So far I have got it working fine, posting back and
updating the record. Great!

However, I now want to make it so that when a user
presses "Update", the caption changes to "Updating..."
and the button disables (to prevent multiple form
submissions).

I can change the caption of the button easily enough, but
if I try disabling the button the server code fails to
run. I suppose this kind of makes sense - why would you
want to run code for a disabled button - however, to
achieve what I want I DO NEED to run the code. I have
tried calling __doPostBack from the buttons onclick event
but this doesn't work.

Any ideas?

Thanks, Paul.

I've tried this but to no avail.

If I disable the button in jscript and then call
__doPostBack(xxx_Update) the update event still doesn't
get called.

But you dont need to call the __dopostback for button. the button sends
the Form without __dopostback.

Try to disable the button with some delay. Instead of "disabled=true", try
"window.setTimeout('PartyEdit_Update.disabled=true ', 100)"

Hi Natty

I have tried this and the button disables but the form
doesn't post back.

Heres the server code I use:
this.Update.Attributes["onclick"] = this.Update.ClientID
+ ".disabled=true;";

And this results in this on the client:
<input type="submit" name="PartyEdit:Update"
value="Update" onclick="PartyEdit_Update.disabled=true;if
(typeof(Page_ClientValidate) == 'function')
Page_ClientValidate(); " language="javascript"
id="PartyEdit_Update" class="UpdateControl" />

I think the validation code checks to see if the button
is enabled and as I've disabled it it fails to run.
