You try this code its work...

Using javascript in aspx page

XML

<asp:TextBox ID="TextBox1" runat="server" onkeyup="document.getElementById('TextBox2').value = document.getElementById('TextBox1').value"></asp:TextBox>
<asp:TextBox ID="TextBox2" runat="server"></asp:TextBox>

or

Enable Autopostback property is true then write this code in codebehind

TextChageEevent

textbox2.text=textbox1.text;

Happy coding....
