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.
