Hi,

take a look at my code:
// ASPX file: (main parts)
 
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
    <title></title>
</head>
<body>
    <form id="form1" runat="server">
    <div>
    
        <asp:DropDownList ID="DropDownList1" runat="server">
            <asp:ListItem>text1</asp:ListItem>
            <asp:ListItem>text2</asp:ListItem>
        </asp:DropDownList>
        <br />
        <br />
        Edit chosen text:<br />
        New value:
        <asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
&nbsp;<asp:Button ID="Button1" runat="server" onclick="Button1_Click" Text="Button" />
    
    </div>
    </form>
</body>
</html>
 
 
 
// THE CODE BEHIND FILE FOR THE ASPX PAGE:
 
Imports System
Imports System.Collections.Generic
Imports System.Linq
Imports System.Web
Imports System.Web.UI
Imports System.Web.UI.WebControls
 
Public Partial Class dropdownlist_text_edit
    Inherits System.Web.UI.Page
    Protected Sub Page_Load(ByVal sender As Object, ByVal e As EventArgs)
        
    End Sub
    Protected Sub Button1_Click(ByVal sender As Object, ByVal e As EventArgs)
        Dim ID As Integer = DropDownList1.SelectedIndex
        Dim newValue As [String] = TextBox1.Text
        
        ' Update chosen dropdownlist item
            
        DropDownList1.Items(ID).Text = newValue
    End Sub
End Class
