Question

How Can I (Or Is It Possible?) Add Item to Html Combobox ServerSide ?
Or Bind It in behind Code in asp.net ?
Does My question Clear?

Answer 1

Do you want to modify a HTML select tag in code behind?

If yes, here is what you need to do:

1. Add runat=server in your tag
   (<select id="s1" runat="server">)
2. To bind the control server side, use
   a datasource (a datatable for
   example), set the datasource s1.DataSource = dt set the property
   s1.DataTextField to the property of
   the datasource you want to bind as
   the text shown to the user, the
   s1.ValueTextField to the property of
   the datasource to use as the value,
   and call the s1.Databind() method
3. To add/remove items (options) you
   can call
   s1.Items.Add/AddRange/Insert/Remove/RemoveAt
   method.
