EditStyle, masks in fields

  • I have two questions wíth reference to EDITSTYLE,WPFEditStyleComboStyle (in Delphi is it Propertíes - Options - Edit Style) - in your Delphi help document wpf_engl.pas see:

    WPFP_PropertyAdd([wobiObject],WPFP_A_EDITSTYLE,WPFEditStyleComboStyle,-1,WPFP2,'EditStyle', 'Edit Style','Style of the edit field (drop down, spin ...)','Options\Field');

    1) How can I open (in form) ComboStyle through keyboard? With mouse is it easy, but I want to do it per keyboard too. Is it possible assign these akcions some shortcut keys?

    2) How can I create mask for this field? (EditStyle, f.e.: calendar, calculator, etc.). For example: When I write some value in field data type calculator, I need through the mask verify accuracy of inserted record - this verification through masks I want to use generally - so in others data type fields too (EditStyleText, TextBox, etc.).
