Question

When i am setting the tabcontainer first tab as active tab through javascript with the following code :

var tc = document.getElementById('<%= tabContainer.ClientID %>');
tc.firstChild.lastChild.style.visibility = "hidden";
tc.set_activeTabIndex(0);

i am getting the exception like:

Propert or method not supported with this object.

note that the second line succefully hides the second tab panel but the third line raises the excception

Any suggestion how to set a tab active through javascript?

Answer 1

Error is generated for line

tc.set_activeTabIndex(0);

We don’t have built-in set_activeTabIndex() method.

You should apply appropriate CSS properties for enabling/disabling tabs.
