asp.net - ActiveTab setting in javascript -

-

when setting tabcontainer first tab active tab through javascript following code : 

var tc = document.getelementbyid('<%= tabcontainer.clientid %>'); tc.firstchild.lastchild.style.visibility = "hidden"; tc.set_activetabindex(0);

i getting exception like:

propert or method not supported object.

note second line succefully hides second tab panel third line raises excception

any suggestion how set tab active through javascript?

error generated line

tc.set_activetabindex(0);

we don't have built-in set_activetabindex() method.

you should apply appropriate css properties enabling/disabling tabs.
