Thank you both for your answers. @ Rajeesh Menoth I get this messge before compiling the code The result of this expression is always 'false' since a value of type bool is never equal to 'null' of type 'bool'. @ Vinay Singh I get this error --Specified cast is not valid.

Hi Use Ternary Operator in c#. Try this : ItemTemplate > asp:CheckBox ID = cbApproved Checked = ' ' runat = server /> ItemTemplate > Reference : http://www.dotnetperls.com/ternary
