Okay, I've got it to where I can check the Combobox to see if the text already resides there:
If Me.RadComboBox1.FindItemExact(Me.RadComboBox1.Text) Is Nothing Then
But how do I add strings to the combobox?
doesn't work, because it's expecting an object, not a string, as you say. Which option should I use to add a string?
Sorry, still trying to get a handle on Object oriented programming.
