Disable submit button after user click

[GS]

Hi,

This is probably known solution but I have not found it in minimum amount of code.
I'd like to disable button on client-side after clicking on it.
Just disabling it in javascript do not produce postback event.
Any examples in ASP.NET 2.0?

Thanks,

Don't know about 2.0, but this works in 1.1, give it a try:

1. in the PageLoad event

if (!IsPostBack)
{
ibSomeButton.At tributes.Add("o nclick",
"this.style.dis play='none';");
// other stuff
}

The "ibSomeButt on" is an ImageButton. However, this will not prevent the
user from hitting refresh which can generate a postback.

This will hide the button and not disable it. But the goad is still
acheived. May this will work:

idSomeButton.At tributes.Add("o nclick", "this.disab led= 'disabled' ");

That's correct, but form my experience users don't notice the disabled
state... and still try to click it... so what I do is hide the button and
unhide some text that tells them to wait...

Thanks,

But I wanted to use Button not ImageButton.
I actuallty found the piece of code to do it, the only problem is that
Page.GetPostBac kEventReference is obsolete and I'm supposed to use some new
ASP.NET 2.0 method which I have not figured out how.

btnGetImportInf o.Attributes["onclick"] =
"this.disabled= true;this.value ='Please wait...';" +
Page.GetPostBac kEventReference (btnGetImportIn fo ).ToString();

I have wanted to do this for a long time, however using a method such
as this one does not work (or at least, did not work for me in v1.1)
because if the page was invalid, the onclick would disable the button,
but the form would not be submitted due to the invalid data.

For example, imagine there is a required field called name, which the
user leaves blank and presses submit. The submit button gets disabled,
and then the user is asked to enter their name. Problem.

Or am I missing something?

If you do the field checking on the client side then yes, you have a
problem -- which can be solved by checking first and only if successful
disable/hide the button. If, however, you allow a postback and do the
checking on the server side everything should be fine since after a postback
the page comes back with the button enabled/visible -- the default value...

I image it's the same... haven't tried though... (my code was using an
ImageButton and I just took it from there)

new ASP.NET 2.0 method which I have not figured out how.

btnGetImportInf o.Attributes["onclick"] =
"this.disabled= true;this.value ='Please wait...';" +
Page.GetPostBac kEventReference (btnGetImportIn fo ).ToString();

Sorry, I'm still in the 1.1 land. Untested code, try this:

btnGetImportInf o.Attributes.Ad d("onclick",
"this.disabled= true;this.value ='Please wait...';");

Code below will not work since disabling button happens before postback and
hence no postback happens when you disable button.
