You can call the function from code behind like this    MyForm aspx cs  protected void MyButton Click object sender  EventArgs e        Page ClientScript RegisterStartupScript this GetType     myScript    AnotherFunction      true       MyForm aspx   lt html xmlns  http   www w3 org 1999 xhtml  gt   lt head id  Head1  runat  server  gt   lt title gt My Page lt  title gt   lt script src  http   ajax googleapis com ajax libs jquery 1 10 2 jquery min js  type  text javascript  gt  lt  script gt   lt script type  text javascript  gt      function Test             alert  hi                ButtonRow   show              function AnotherFunction                 alert  This is another function           lt  script gt   lt  head gt   lt body gt   lt form id  form2  runat  server  gt   lt table gt       lt tr gt  lt td gt               lt asp RadioButtonList ID  SearchCategory  runat  server  onchange  Test     RepeatDirection  Horizontal   BorderStyle  Solid  gt                  lt asp ListItem gt Merchant lt  asp ListItem gt                  lt asp ListItem gt Store lt  asp ListItem gt                  lt asp ListItem gt Terminal lt  asp ListItem gt               lt  asp RadioButtonList gt           lt  td gt       lt  tr gt       lt tr id  ButtonRow style  display none  gt            lt td gt               lt asp Button ID  MyButton  runat  server  Text  Click Here  OnClick  MyButton Click    gt           lt  td gt       lt  tr gt       lt  table gt    lt  form gt
