Call javascript function from codebehind in asp.net

Here i will explain how to call javascript function from codebehind without assigning it to any control in asp.net.

We can call javascript functions in two ways

first way is

System.Web.UI.ScriptManager.RegisterClientScriptBlock(Page, typeof(Page), "Script", "document.getElementById('" + button2.ClientID + "').style.display='none';", true);

Seconda way you can call javascript function also

System.Web.UI.ScriptManager.RegisterClientScriptBlock(Page, typeof(Page), "Script", "MyJavascriptFunction();", true);

Like this we can call the javascript functions or buttons in codebehind without assigning it to any control
