Solution 1

Use the SelectedIndex property[^].

Once you have the value you have selected, fetch the values related to this index (the ones that you want to show in textboxes).
These will need to be fetched from the database or a temporary memory store.

Display these values.

XML

<asp:DropDownList  ID="DropDownList1"  runat="server"   AutoPostBack="true"          OnSelectedIndexChanged="DropDownList1_SelectedIndexChanged"    >
             <asp:ListItem>HyperLink</asp:ListItem>
             <asp:ListItem>PasswordRecovery</asp:ListItem>
             <asp:ListItem>PlaceHolder</asp:ListItem>
             <asp:ListItem>LoginName</asp:ListItem>
             <asp:ListItem>Label</asp:ListItem>
        </asp:DropDownList>

<asp:textbox id="TextBox1" runat="server" xmlns:asp="#unknown"></asp:textbox>

XML

<script runat="server">
    protected void DropDownList1_SelectedIndexChanged(object sender, System.EventArgs e)
    {
        TextBox1.Text = "You Selected: " + DropDownList1.SelectedItem.Text;
    }
</script>

You can use database to store records.
