Databinding within an asp:textbox control

[Luis Esteban Valencia]

am trying to databind within an asp:textbox control. I have tried many
variations found here but nothing seems to work. It works fine if I use a
regular HTML textbox input though. Here is what I have tried:

<asp:textbox id='<%#DataBinder.Eval(Container.DataItem, "EmailID")%>'
cssclass="textbox" runat="server"><%#DataBinder.Eval(Container.DataItem,
"Email")%></asp:textbox>

I get '<%# DataBinder.Eval(Container.DataItem, "segEmailID").ToString() %>'
is not a valid identifier.

Then

<asp:textbox id="<%#DataBinder.Eval(Container.DataItem, "EmailID")%>"
cssclass="textbox" runat="server"><%#DataBinder.Eval(Container.DataItem,
"Email")%></asp:textbox>

I get 'The server tag is not well formed.'

Finally I tried without the #:

<asp:textbox id='<%DataBinder.Eval(Container.DataItem, "EmailID")%>'
cssclass="textbox" runat="server"><%DataBinder.Eval(Container.DataItem,
"Email")%></asp:textbox>

I get '<%DataBinder.Eval(Container.DataItem, "segEmailID").ToString() %>' is
not a valid identifier.

Thanks for your help! BTW - this asp:textbox control is within a
repeater.....

Thanks again!
