How to set multiple items as selected in ListBox?

asp.net, c#, listbox, listitem, selected

Solution

What about setting the `Selected`-property of the `ListItem`?

var names = new List<string>(new string[] { "ragu", "raju" });

foreach (var item in lbto.Items)
{
    if (names.Contains(item.Text))
        item.Selected = true;
}

Problem

I have one ListBox with selection mode of multiple. In code behind, I want to set some values as selected. These values are present in a ListItems[] named 'Names'. HTML code: ``` <asp:ListBox ID="lbto" class="chosen" runat="server" Width="450px" Height="20px" SelectionMode="Multiple"> <asp:ListItem>Mandy</asp:ListItem> <asp:ListItem>Amit</asp:ListItem> <asp:ListItem>sundar</asp:ListItem> <asp:ListItem>ragu</asp:ListItem> <asp:ListItem>raju</asp:ListItem> </asp:ListBox> ``` ListItem[] Names contains 'ragu' and 'raju'. Now, when the page loads, the ListBox should contain 'ragu' and 'raju' as selected values.
