Bind and Eval query

Hi

I have read the difference between the Eval and Bind.

Eval - One way binding

Bind - Two Way binding

<asp:GridView ID="GridView2" runat="server"> 
        <Columns> 
            <asp:TemplateField> 
                <ItemTemplate> 
                    <asp:TextBox ID="txtName" runat="server" Text='<%# Bind("name") %>'></asp:TextBox> 
                </ItemTemplate> 
            </asp:TemplateField> 
        </Columns> 
</asp:GridView>

Select allOpen in new window

And

<asp:GridView ID="GridView2" runat="server"> 
        <Columns> 
            <asp:TemplateField> 
                <ItemTemplate> 
                    <asp:TextBox ID="txtName" runat="server" Text='<%# Eval("name") %>'></asp:TextBox> 
                </ItemTemplate> 
            </asp:TemplateField> 
        </Columns> 
    </asp:GridView>

Select allOpen in new window

gives the same result. Then how does these 2 things differ.
