Good one +5!

Solution 1

you can try such as :

XML

finally
{
string script = "<script language='javascript'>yourFunction();</script>";
 Page.RegisterClientScriptBlock("xxx", script);
}

and the function should be in the head section of page such as:

JavaScript

<script type="text/javascript">
        function yourFunction() {
            alert("Hai");
            return;           
        }
    </script>

Solution 4

C#

try
      {
          //my code here
      }
      catch (Exception ee)
      {
         // throw ee;
      }
      finally
      {

          ScriptManager.RegisterClientScriptBlock(Page, this.GetType(), "CallJSFunction", "YourFunctionName()", true);
      }

you can write your js function which you can set in a string variable like this

Java

try
      {
          //my code here
      }
      catch (Exception ee)
      {
         // throw ee;
      }
      finally
      {
string jsFunction="alert('Process comlete');"
          ScriptManager.RegisterClientScriptBlock(Page, this.GetType(), "CallJSFunction", "jsFunction", true);
      }

if you are using Script Manage on your page then the above answer will work other wise you need to add this one
Page.ClientScript.RegisterStartupScript(this.GetType(), "CallJS", "JSFunctionName();", true);
