Hello,
 
I have the following code that works if the values are true/false. If I have a null value I get an exception.
 
- <ItemTemplate>  
-     <asp:CheckBox ID="cbApproved" Checked='<%# Convert.ToBoolean(Eval(ValApproved")) %>' runat="server"/>  
- </ItemTemplate>  
Any ideas how to fix that?  
 
Thank you in advance.
