Why Script block is getting created dynamically (VS 2010)?

Hi 

       I have created an application using ASP.NET, C# and run the same in Visual Studio 2010. For each button click event, code behind gets executed then around 20 script block[dynamic] file gets created before the event occurs. It increases the page load time/ even occurrence time. 

      The solution which I tried by surfing through net is run the application without debugging. In that case script block has not created and felt loading time has got reduced(not much). Kindly help me to reduce the loading time(should not take extra after code behind gets executed).

Thanks
