Control is basically a single line text editor. Data source can be attached to the control, enabling the end user to manipulate with data. Build in context menu is available in the control allowing the end user to perform standard text editing operations.

These operations include:

• Undo last modification.
• Working with the clipboard. Operations Cut, Copy, Paste and Remove.
• Selecting all text.

Control can be used to display value of a field or to serve as a parameter provider. With the help of control's properties it is possible to edit value of a specific data source and to save changes directly to the database.

Control has many properties that define its appearance, design, behaviour etc.
