I set the CLISTOBJ1.lEnabled prperty of CListObjEdit's Property to .F.

Then I droped my custom object on the form and named it ProgRoutinObj
In the CLISTOBJEdit's(which is named lesProgroutin) postinitHook property I added
This.ChangeBizObj(This.Parent.ProgRoutinObj)

In the ProgRoutinObj business objects OnBizObjEmpty and PostRequeryHook methods I added
This.Parent.lseProgRoutin.SetButtonEnabledStatus()
and in its PostInitHook property has the following code
This.AddViewParameter('vp_Programers_IPID', 'v_programers.ipid')

where I want it to pick the parameter value from the v_Programers view and vp_programers_ipid is the view paramter which is used to filter the records in v_progroutin view

the lAutoPrimaryBiz setting of the proRoutinObj is .F.

Yes I am selecting the page on which the object is lying. It doesnot allow me to open the Page at all and give me the error message. I am using the toolbar to open the entire project which consist of a form with four tabs. I am not using a tool bar to open this particular tab.

Thanks for your concern
