Forms

Yes if you want to maximize the form when opened; otherwise, No. The default is No.

This property is evaluated when the form is opened; it does not impact associated subforms. You can set this property at runtime using C/AL code.

If the MinimizedOnOpen Property is set to No, then MaximizedOnOpen must be set to Yes.

This property is not supported on pages in the RoleTailored client.
