    '                Me.Label1.Text = count - 1 & " " & "document/s found."
    '             End If
    '          End While

    '   End Select
    'End Sub
End Class

hope somebody can help me

You should have a different SQL clause depending on your search box. Procedure LoadPeople should start like this

Dim sqlQuery As String

Select Case ComboBox1.SelectedValue.ToString()
    Case "Name"
        sqlQuery = "SELECT * FROM reservation ORDER BY Name"
    Case "Room type"
        sqlQuery = "SELECT * FROM reservation GROUP BY RoomType"
End Select

Since you execute this code from the form's load event, you have to fill search combo in there and set a proper combobox index in order to load "default view" (which could be empty too).
