How to enable/disable the textboxes with autopostback.

I have 5 textboxes.
<asp:TextBox id="t1" runat="server" Text=""/>
<asp:TextBox id="t2" runat="server" Text="" Enabled="false"/>
<asp:TextBox id="t3" runat="server" Text="" Enabled="false"/>
<asp:TextBox id="t4" runat="server" Text="" Enabled="false"/>
<asp:TextBox id="t5" runat="server" Text="" Enabled="false"/>

I want to enable t2 if t1 is entered.
Similarly t3 should be enabled if t2 is entered.
and so on.

with Autopostback=true

If you need to change the state when TB is entered, you need client side script. Autopostback does nothing with this.
Add this

protected void Page_Load(object sender, EventArgs e)
    {
      t1.Attributes.Add("onfocus", "test('" + t2.ClientID + "')");
    }

Open in new window

and somewhere in the HTML - this

<script>
      function test(id) {
        document.getElementById(id).disabled = true;
      }
    </script>

Open in new window

Hope you'll get the idea.

This may be easier on the client instead.

$("input").change( function() {
    $(this).next("input").attr( {disabled: false} );
});
