How to convert true/false to yes/no in grid view column?

Question

Hi All,

I have one boolean column in grid view, which returns true/false. Instead of that I need to show yes/no.

<asp:TemplateField HeaderText="Has Included">
        <ItemTemplate>
                   <asp:Label ID="l8" runat="server" Text='<%# Eval("hasIncluded") %>'></asp:Label>
        </ItemTemplate>
</asp:TemplateField>
