Eval format in textbox

I have been trying to apply Eval on textbox which its mode is TextMode="Date". The date is not loading in to the text box and this is because the textmode. It seems to be that the Eval format is not working at all. When I remove the textmode it works. I have been trying several on variations and non of them have worked.

Here is some of them:

<asp:TextBox ID="birthdayTB" runat="server" Text='<%# Convert.ToDateTime(Eval("Birthday")).ToString("d")  %>'  TextMode="Date"></asp:TextBox>

<asp:TextBox ID="birthdayTB" runat="server" Text='<%# Eval("Birthday", "{0:dd-MM-yyyy}")  %>'  TextMode="Date"></asp:TextBox>

<asp:TextBox ID="birthdayTB" runat="server" Text='<%# Eval("Birthday", "{0:d}")  %>'  TextMode="Date"></asp:TextBox>

How can I make this work? Thank you.
