PB.Net, Datawindow and Readonly

Hi everyone!

Im pretty new to powerbuilder and its  my first time to build an app using powerbuilder.net

my situation here is, I have created a data entry application that consists of 2 datawindow to show the product, and product version respectively. The values/contents of the version_datawindow are dependent on the index of product_datawindow. i have set both of the datawindows to dw_prod.object.datawindow.@readonly=true/dw_ver.object.datawindow.@readonly=true. I have a ribbon menu control for my action handlers.

Whenever i press the Add button, two datawindows will set is @readonly property to false.

my question is this.

1. when i press the ADD button, the datawindows are still on @readonly=true
   • i have put the protect in the script so whenever the add is clicked, the newrow is only editable
   • i have put tab order in my datawindows
2. is it a bug that datawindows cannot change @readonly property?
3. what would be the reasons why i cannot type on my datawindow?

notes:

i have tried this methods

dw_prod.object.datawindow.readonly='yes'/'no';

dw_prod.modify("Datawindow.readonly='Yes'/'No'")

please help.

thanks guys and more power!
