Adding first blank row to combobox

Hi
I am populating the combobox with following code. I would like to ADD AND display a blank row as first row while loading the combobox and want to get rid of -1.
private void Fillcmbmenusubgroupid()
{
try
{

bucketmenusubgroup.PredicateExpression.Add(MenusubgroupFields.Flag ==
StandardFlag.recordvalidflag);
adaptermenusubgroup.FetchEntityCollection(datasourcemenusubgroup, bucketmenusubgroup,
0,
new SortExpression(
MenusubgroupFields.Description |
SortOperator.Ascending));

cmbmenusubgroupid.DataSource = datasourcemenusubgroup;
cmbmenusubgroupid.ValueMember = "MENUSUBGROUPID";
cmbmenusubgroupid.DisplayMember = "DECRIPTION";
cmbmenusubgroupid.SelectedIndex = -1;

}
catch (Exception ex)
{
GlobalErrorHandler.LogMessage(ex.StackTrace);
}
finally
{
adaptermenusubgroup.CloseConnection();
}
}

<asp:DropDownList ID="DropDownListID" AppendDataBoundItems="true" runat="server">
<asp:ListItem Text="Default text" Value="Default value" />
</asp:DropDownList>

Append data bound items = true make sure that it will not remove your default item

Try Create a object of ListItem specify value and text and then set the selected property of the listitem object to true and add listItem object to dropdownlist items collection. If the default that you want to set is already in your dropdown list then you can iterate over dropdownlist Items collection and set the selected property of the desired item in the collection.
