What type is notesVisible? If it's not a bool but an int:

Visible='<%#((int)Eval("notesVisible")) == 1 ? true : false%>'

Edit: Since you have mentioned that there are nulls:

Visible='<%#Eval("notesVisible") == DBNull.Value ? false : Convert.ToBoolean(Eval("notesVisible"))%>

you need to set visible property with boolean vale "true" or "false"

Eval("notesVisible") is a object not a boolean

Please use it as blow 

Visible='<%#(Eval("notesVisible").ToString()=="somthing"?true:false)%>'

I hope it will help you.
