How to apply search in combobox in custom textbox header

[Mohamad]

hi

I applied the solution in the next link:

but I have problem with the next function:

 Private Function FilterItem(ByVal data As Object) As Boolean

        If (TryCast(data, USState)).LongName.ToLower().Contains(Me.TextBox.Text.ToLower()) Then

            Return True

        End If

        Return False

    End Function

I don't have USState class because my Combobox source is  Datatable, so how we can solve this problem 

[Mohamad]

any help please!
