Hi Kapil,
As per my Knowledge, better to specify xmllist as dataprovider to menubar
and getMenuByID function doesnt have finite number. It is better to write
code that when you click on some component it has to activate. Because if it
has infinite number it will compile fast and get stuck somewhere. In if
condition you need to wirte as
if(condition1)
{
menuBarXML.DataProvider = menuItem.id;
}
I think this will help you a little bit to solve your issue.
Regards,
Kiran
