Hello Ignacio,
I'm using 2 TEdit-controls, TEdit1 and TEdit2.=20
When the TEdit1:Value is empty I wish the TEdit2 being disabled.=20
To simulate the WHEN-clause I use the TEdit2:OnCheckState().
METHOD Edit2CheckState( oSender ) CLASS TForm1
RETURN !EMPTY(::oEdit1:Value)
Please take a look to the example.
TEdit1:Value =3D "a"
TEdit2 is enabled
Now delete the "a" and try to leave the TEdit1-control by the Tab-key.=20
The cursor disappears and can't be moved by Tab but only with the mouse.
Regards
Ingo
