Use the tertiary expression '?':

<asp:TemplateField HeaderText="Name">
                <ItemTemplate>
                    <%# Eval("Bla Bla Bla").ToString().Length <= 15 ? Eval("Bla Bla Bla") : Eval("Bla Bla Bla").ToString().Substring(0,15) %>
                </ItemTemplate>
            </asp:TemplateField>
