I have a requirement where I need to determine the index of a TabPanel based on its ID in order to make it active on Page.Load. I can't use the index directly as there can be a varying number of tabs. And trying to set the TabContainer ActiveTab property using the ID is seemingly not supported. I see that a TabPanel has a TabIndex property, but if I look at this on Page.Load it is always zero. Any ideas why this is the case?
