Hi,

I'm trying to get the "applying the user-selected theme" exercise in Chapter 6 to work and can't. The behaviour is that the theme-switching works for the login page but not for the default/home page. In the case of the home page the theme switches successfully from Monochrome to DarkGrey when the latter theme is selected in the drop down list, but when I then select Monochrome in the drop down again nothing happens. If I follow the link to the login page and select 'Monochrome' in the drop down it switches themes as expected (and if i follow the link back to the home page the correct theme is set there too).
I can see from setting a breakpoint in the ThemeList_SelectedIndexChanged() function in master.cs that that function isn't getting called when I select 'Monochrome' in the dropdown list from the home page and I can't see why that might be - any ideas?

thanks
Lorna

found my problem. At some point in an earlier exercise I had set the ViewStateMode to disabled for my default page; doh. I haven't worked out why this causes the behaviour I saw (ie why would disabling viewstate mean I could switch from monochrome to darkgrey, but not back again - why does the ThemeList_SelectedIndexChanged() function only get called the first time. ), but I'll mull that over...
