XML

<asp:ListBox ID="ListBox1" runat="server">
            <asp:ListItem Value="1">Add</asp:ListItem>
            <asp:ListItem Value="2">Sub</asp:ListItem>
            <asp:ListItem Value="3">Mul</asp:ListItem>
            <asp:ListItem Value="4">Div</asp:ListItem>
        </asp:ListBox>
        <br />
        <asp:Button ID="Button1" runat="server" Text="Button" />

C#

protected void Button1_Click(object sender, EventArgs e)
        {
            ListItem l = new ListItem("Sub", "2");
            ListBox1.SelectedIndex = ListBox1.Items.IndexOf(l);
        }

Hope this code may help you.....

Hello,

If you need to select "Libish" from the list box, use the following code.

XML

<asp:Button ID="Button1" runat="server" onclick="Button1_Click" Text="Button" />
    <asp:ListBox ID="ListBox1" runat="server">
        <asp:ListItem>vinod</asp:ListItem>
        <asp:ListItem>Alex</asp:ListItem>
        <asp:ListItem>Libish</asp:ListItem>
    </asp:ListBox>

protected void Button1_Click(object sender, EventArgs e)
{
        ListBox1.SelectedValue = "Libish";
}

Thanks!!!
