Hi,

Is it possible to change date format on an editmask control?

When I try to save em_date.Mask = 'dd/mm/yy' I get an error:
"A readonly property can be modified only in an event or function in its parent class"

Is this normal?

Regards,
Marcin

Go to the ancestor of the object in which you havew the EditControl to be modified.
Change the value of the mask in the ancestor in which the control is initially defined (it won;t be ReadOnly).

Just be aware that altering the parent object changes the mask for ALL of the descendants.

Hi Marcin;

  You cannot update that property is what the error message is about. If you open the PB IDE's Object Browser, you'll see that the "mask" property is marked "non-writable", as follows:

 

  You should be using the SetMask() method instead.

HTH
