Features:

• Data Binding: C1Input controls can function both in unbound and in bound mode. In bound mode, a controls Value is bound to a data source field. C1Input controls support data binding to all .NET data sources. This includes ADO.NET data source objects such as DataTable, DataView and DataSet, and also ComponentOne DataObjects components such as C1ExpressTable, C1ExpressView, C1ExpressConnection, C1DataView, C1DataTableSource and C1DataSet
• Formatting Data: C1Input controls support a rich formatting model, which enables developers to customize the appearance of a controls text in almost any way imaginable. The main function of Formatting is to display a string Text representation of a typed or stored Value
• Validating Data: C1Input controls support data validation both of the raw input string (PreValidation) and of the typed value entered by the user (PostValidation)
• Dropdown and Increment Buttons: The specialized C1Input controls for date-time and numeric editing, C1DateEdit and C1NumericEdit controls support dropdown and increment/decrement (up/down) buttons. Button visibility is controlled by the ShowDropDownButton and ShowUpDownButtons properties
• Error Handling : When C1Input detects an error while parsing or validating input value it fires the ValidationError event, then, by default, it shows an error message. The default behavior can be changed and customized in different ways
• Handling NULL and Empty Values: NULL values (DbNull) can be difficult to handle without appropriate tools. C1Input provides flexible rules for handling nulls allowing the programmer the ability to solve this problem in practically any circumstance
