In my planned C# MONO application end user can add new columns to database tables and change many char column widths.

I have table which describes all business data input forms

InputForms( Formid, MasterTableName, FieldNameOrExpression, Format, InputMAsk )

I need to allow users to edit data by creating dynamically grids and data edit forms described in this table.

Where to find sample code which implements this ?
MM business object properties and typed datasets are fixed at design time.

How to use dynamics properties in typed datasets and adds them to business objects at runtime ?

IdeaBlade DevForce free framework ( www.ideablade.com ) allows to add custom properties to business objects at runtime.
IdeaBlade has also Dynamic Entity Types which creates business objects at runtime.

Where to find sample code which implements similar functionality ?
