probably your StatusField isn'T of Type bool?
if it is nummeric (0,1) you could do this:
Checked='<%# 1==DataBinder.E val(Container.D ataItem, "Status")%> '>
if it'S text ("true", "false") you could do this:
Checked='<%# "true" == DataBinder.Eval (Container.Data Item, "Status")%> '>
I guess you got the idea ...

Specified cast is not valid.
That suggests that DataBinder.Eval (Container.Data Item,"AdminRigh ts")
isn't returning an integer. Try writing to the debug log:
DataBinder.Eval (Container.Data Item,"AdminRigh ts").GetType( )

Right. In that case, you need to either cast to byte, and all should be
well.

Yes it will heal if you put a cast on it. It will get well.

Well I'd start by making your code more readably in the first place -
if you break that single line up into several, chances are it'll become
obvious.
That seems a strange compilation error to me, but SelectedValue returns
a string, not an integer. You'll need to use Int32.Parse or
Convert.ToInt32 in order to convert a string to an integer.

I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
