Hello Sai, Shubham Kumar Comment is correct. Because in code behind it can t possible get div id/properties with out mention runat="server" attribute. So you need div hide and show use plain HTML and Java script only. Like below HTML Code id = "myBox" style = " display : none ; " > Some Text ....... button onclick= "myFunction()" > Click me /button > Java Script Code function myFunction() { document . getElementById ( 'mybox' ). style . display = "block" ; }

Hi Sai, Try this it will work. function showhide() { if (document.getElementById(" ").style.display == "none") { document.getElementById(" ").style.display = "block"; } else { document.getElementById(" ").style.display = "none"; } } This is just for show hide div.
