Hi Daniil,
Ok Let me explain.
I have a masterpage with menupanel on the left and a header control and footer control.andon clicking the menu items, i want to open the child pages in different tabs.exactly same as the way we see in the ext.net examples page.
For this i am creating a tabpanel inside the contentplaceholder in the master page and trying to open each page inside it in different tabs..but when i call the javascript function to open/add tabs on clicking menuitem the tabpanel isnt passed as a result it shows null..and hence i end up getting error.
Will you please help me achieve this??
i have been breaking my head on this for the past 2 weeks no but still no luck.
here i am posting my masterpage code:
