This page will be helpful for you

// Get a ClientScriptManager reference from the Page class.
ClientScriptManager cs = Page.ClientScript;
Type cstype = this.GetType();
String csName = "MyAlertFunction";

// Check to see if the startup script is already registered.
if (!cs.IsStartupScriptRegistered(cstype, csName))
{
  String jsFunction = "yourFunctionHere()";
  cs.RegisterStartupScript(cstype, csName, jsFunction, true);
}

user scrip manager

    ScriptManager.RegisterStartupScript(this, typeof(string), "SHOW_ALERT",  "alert('')", true);

where in place of alert you can put your javascript code, next argument true puts in script tags automatically so you dont have to write them.
