DataGridView Control Architecture (Windows Forms). 3 minutes to read.In this articleThe control and its related classes are designed to be a flexible, extensible system for displaying and editing tabular data. These classes are all contained in the namespace, and they are all named with the 'DataGridView' prefix. Architecture ElementsThe primary companion classes derive from. The following object model illustrates the inheritance hierarchy.The class provides a reference to the parent control and has a property, which holds a value that represents a combination of values from the enumeration.The following sections describe the companion classes in more detail. DataGridViewElementStatesThe enumeration contains the following values:.The values of this enumeration can be combined with the bitwise logical operators, so the property can express more than one state at once.

For example, a can be simultaneously,. Cells and BandsThe control comprises two fundamental kinds of objects: cells and bands. All cells derive from the base class. The two kinds of bands, and, both derive from the base class.The control interoperates with several classes, but the most commonly encountered are,. DataGridViewCellThe cell is the fundamental unit of interaction for the. Display is centered on cells, and data entry is often performed through cells. You can access cells by using the collection of the class, and you can access the selected cells by using the collection of the control.

The following object model illustrates this usage and shows the inheritance hierarchy.The type is an abstract base class, from which all cell types derive. And its derived types are not Windows Forms controls, but some host Windows Forms controls. Any editing functionality supported by a cell is typically handled by a hosted control.objects do not control their own appearance and painting features in the same way as Windows Forms controls.

Instead, the is responsible for the appearance of its objects. You can significantly affect the appearance and behavior of cells by interacting with the control's properties and events. When you have special requirements for customizations that are beyond the capabilities of the control, you can implement your own class that derives from or one of its child classes.The following list shows the classes derived from:.Your custom cell typesDataGridViewColumnThe schema of the control's attached data store is expressed in the control's columns. You can access the control's columns by using the collection. You can access the selected columns by using the collection. The following object model illustrates this usage and shows the inheritance hierarchy.Some of the key cell types have corresponding column types. These are derived from the base class.The following list shows the classes derived from:.Your custom column typesDataGridView Editing ControlsCells that support advanced editing functionality typically use a hosted control that is derived from a Windows Forms control.

These controls also implement the interface. The following object model illustrates the usage of these controls.The following editing controls are provided with the control:.For information about creating your own editing controls, see.The following table illustrates the relationship among cell types, column types, and editing controls. Cell typeHosted controlColumn typen/an/an/an/aDataGridViewRowThe class displays a record's data fields from the data store to which the control is attached. You can access the control's rows by using the collection. You can access the selected rows by using the collection. The following object model illustrates this usage and shows the inheritance hierarchy.You can derive your own types from the class, although this will typically not be necessary. The control has several row-related events and properties for customizing the behavior of its objects.If you enable the control's property, a special row for adding new rows appears as the last row.

This row is part of the collection, but it has special functionality that may require your attention. For more information, see. See also.Recommended Content.

IntroductionSince.NET 4.0, Microsoft is shipping a DataGrid control that provides all the basic functionality needed, like:.To show a basic data grid, just drop a DataGrid control to your view and bind the ItemsSource to a collection of data objects and you're done. The DataGrid provides a feature called AutoGenerateColumns that automatically generates column according to the public properties of your data objects. It generates the following types of columns:. TextBox columns for string values. CheckBox columns for boolean values. ComboBox columns for enumerable values.
