Disable asp.net button after click to prevent double clicking
Here is a solution that works for the asp.net button object. On the front end, add these attributes to your asp:Button definition:
<asp:Button ... OnClientClick="this.disabled=true;" UseSubmitBehavior="false" />In the back end, in the click event handler method call, add this code to the end (preferably in a finally block)
myButton.Enabled = true;
I have found this, and it works:
btnSave.Attributes.Add( "onclick", "this.disabled = true;" + ClientScript.GetPostBackEventReference(btnSave, null) + ";");
Check this link, the most simplest way and it does not disable the validations.

If you have e.g.
<form id="form1" runat="server"> <asp:Button ID="Button1" runat="server" Text="Button1" OnClick="Button1_Clicked" /> </form>Then you can use
<script type = "text/javascript"> function DisableButton() { document.getElementById("<%=Button1.ClientID %>").disabled = true; } window.onbeforeunload = DisableButton; </script>To disable the button if and after validation has succeeded, just as the page is doing a server postback.
