i want access getdata() method html button..help.plz

we can not call server side function directly client (without registering on server, refer @fubo answer below this), if can security threat. call function browser adding raw html web page, case.

however can postback , in page_load can validate our input button call desired method.

  protected void page_load(object sender, eventargs e)         {             if (!ispostback)             {                 testdiv.innerhtml = @"<input type=""button"" id=""btnsubmit"" value = ""click here"" runat = ""server"" onclick=""__dopostback('btnsubmit','')""/> ";             }             else             {                 var eventtarget = request.form["__eventtarget"].tostring();                 if (eventtarget == "btnsubmit")                 {                     getdata();                 }             }         }          public string getdata() {             response.write("clicked.");         }
