Here is my handler for when the button is clicked $('div#code_apply_btn').click(function() { $(this).html('PLEASE WAIT');

I will provide additional information if necessary. [WebMethod] public byte[] Transfer() { return File.ReadAllBytes(@"4MBFile.zip"); } I am using C# and .NET 4. (I changed the initial settings for the project from 2.0 to 4.0). A webmethod uses a kind of serialization so I guess there will be some overhead. Am i really

When I use URLRewriting the URL is different in instances that I supply a parameter from instances when I do not. Can anybody help me with this

The server side has the traditional Web Method implemented so as to capture data sent and execute SQL queries based on it.

问题 I have a LinkButton on a page that performs a post-back, but also has an onClientClick event. The idea is to set some session variables in the background from client-side data (don't ask). I've placed a break point in the web method to step through our code, and what we're experiencing is that depending on the browser, the PageMethods may return a success message, failure message, or no message at all . Additionally, the web method may or may not get called, regardless of the PageMethods
