Hi, i have the a combobox named cmbYear, inside the combobox have the items year eg. 2014, 2013, etc. The items are bind through data source as below:
<dx:ASPxComboBox ID="cmbYear" runat="server" ClientIDMode="AutoID"
        DataSourceID="yearDataSource" ValueType="System.String"
        ValueField="Years" TextField="Years" SelectedIndex="-1">
           <dx:ListBoxColumn Caption=" " FieldName="Years" />
    <asp:SqlDataSource ID="yearDataSource" runat="server"
        ConnectionString="<%$ ConnectionStrings:vsCustomizationRequestConnectionString %>"
        SelectCommand="SELECT DISTINCT YEAR(CreateDate) AS Years FROM CRF_Project ORDER BY Years DESC">

and now i want to add a new item on TOP or in another word as the first item in the combobox and i use the following codes:
cmbYear.Items.Insert(0, new ListEditItem("Latest"," "));

if (cmbYear.SelectedItem != null)
    if (cmbYear.SelectedItem.Text == "Latest")
        yearsStatus = DateTime.Now.ToString("yyyy");
        yearsStatus = cmbYear.SelectedItem.Text.TrimEnd();
    yearsStatus = DateTime.Now.ToString("yyyy"); ;

but when i run my program, the new item which is "Latest" cannot be displayed inside the combobox, any idea?

Remove the current combobox and insert a new combobox.
