When i rey to use a combox i can select from the list but every option i select nothing is show in the control. The value is correct and save to my controlsource but i can't see the description...

The controlsource is a property of an object in my form and this is Init() method of the class i use for all these kind of combo

DoDefault()
Local lcAlias
lcAlias = This.xcAlias
If !Used(lcAlias)
Select * From tTemp Order By Des1 Into Cursor (lcAlias)
Use In tTemp
EndIf
If Used(lcAlias)
This.BoundTo = .T.
This.RowSource = lcAlias + ".Des1,Id"
This.RowSourceType = 2
Endif

The controlsource is set in the form where i use the combo to "thisform.oo.idzo" and thisform.oo.idzo contains a numeric value...
In this control i show two columns, whetre i wanto to show the value from the first and return in the controlsource the value of the second column...
