Remarks

Use the pfx-default-value property value to evaluate events and properties using Power Fx expressions instead of static default values. You can use this to:

  • Responsively size the control
  • Access connectors
  • Provide sample data
  • Reference theme properties
  • Custom events

Note

  • You can use any Power Fx expression, but you must make sure the expression is valid when importing the control.
  • If you use inner quotes or other special characters, wrap the value in single quotes, For example: pfx-default-value='"Test"'
  • You can reference other controls (including screens) and their properties. Write these references as: %ControlName.ID%.ControlProperty. For example: pfx-default-value='SubmitForm(%MyFormName.ID%)'
  • Write enums, like DisplayType and ScreenTransition as: %EnumName.RESERVED%.EnumValue. For example: pfx-default-value='Back(%ScreenTransition.RESERVED%.Cover)'
  • If pfx-default-value is included, then it takes precedence over default-value.
