You can just place this line in a JavaScript function     doPostBack  btnSubmit   OnClick      Or do something like this       btnSubmit   trigger  click

var clickButton   document getElementById   lt    btnClearSession ClientID   gt     clickButton click      That solution works for me  but remember it wont work if your asp button has      Visible  False    To hide button that should be triggered with that script you should hide it with  lt div hidden gt  lt  div gt

You can fill a hidden field from your JavaScript code and do an explicit postback from JavaScript  Then from the server side  check that hiddenfield and do whatever necessary
