Here is my code so far:
If item.IsInEditMode Then
Dim indx As Integer = ctlUserCombo.FindItemIndexByText("Test, Sabo")
Dim cmbo As RadComboBox = CType(item.FindControl("ctlUserCombo"), RadComboBox)
Dim cbox As RadComboBoxItem = CType(cmbo.Items(indx), RadComboBoxItem)
 cmbo.Items(indx).Enabled = False
So I am able to change the Enabled property to False...what I need to be able to do is set the combobox to "Checked".  However the RadComboBoxItem does not have a 'checked' property.  Anyone know how to get the combo box to show checked = true for individual items in the combobox?  
Thanks.
