'Changenameid' is some custom form's method which makes some action based on popup selection. I just copied this code from one my project.

>I understand what you make in the init event of the form
>and after in the grid.column.textbox, but could you explain what
>this line do :
>on selection popup popNames1 frsMain.frmNames.changenameid()
>I mean this part : frsMain.frmNames.changenameid()

>>It works in 3b in slightly different way:
>>*** Form.Init event
>>*** prepare right-click menu
>>define popup popNames1 margin color scheme 4
>>define bar 1 of popNames1 prompt 'Artist'
>>define bar 2 of popNames1 prompt 'Creator'
>>define bar 3 of popNames1 prompt 'Publisher'
>>define bar 4 of popNames1 prompt 'Unknown'
>>on selection popup popNames1 frsMain.frmNames.changenameid()
>>*** grid.column.textbox.rightclick
>>activate popup popNames1 at mrow(),mcol()
>>

>>>Your are all right with your suggestions but, if found that with vfp 3.0b
>>>this command is not available :
>>>DEFINE POPUP mypopup SHORTCUT RELATIVE FROM MROW(),MCOL()
>>>SHORTCUT is not available with vfp 3.0b. I choose to make a form with
>>>the options i want instead of using the right click with a popup menu.
