single-click button / ajax

Hi,
anyone know how to write a single-cilick button? [after click button
is being disabled while the method is executing]
I use this:
<asp:button id="ButtonAdd" runat="server" text="Anuluj"
onclick="Click_ButtonAdd" />
if ( !isPostBack){
ButtonAdd.Attributes.Add("onclick",
ClientScript.GetPostBackEventReference(ButtonAdd, "") +
";this.value='Processing Credit Card Payment...';this.disabled =
true;");
}
and I have with this a big problem.
For time to time this method is executing 2 times. I dont know why.
Instend of add 1 record to database it add 2 records.<laziers@.gmail.com> wrote in message

Aha, right, it is a different problem.
Disabled buttons don't fire postbacks.
You can do something like this:
OnClientClick="this.value='Processing Credit Card
Payment...';this.disabled=true;document.forms[0].submit()" />
It won't fire the server-side onclick event but will cause a postback. You
can communicate the action you want the server to take in a hidden input
field.

disabling after postback is trival.
<asp:button id="ButtonAdd"
runat="server"
text="Anuluj"
onclientclick="window.setTimeout(function(){this.disabled=true;};"
onclick="Click_ButtonAdd" />
but its a bad solution. if the postback takes too long and the user hits f5
(refresh), you will get a second postback. you should code for double
postbacks. render a transaction guid in a hidden field (or viewstate). then
store the guid with the payment posting. your code can then check if its bee
n
processed, and display the proper response.
