Class GridModel

This is the GridModel class that holds all data information about a grid and provides methods to completely initialize a grid and attach it later to a GridControlBase so that its contents can be rendered to the screen.

Syntax

public class GridModel : IGridVolatileCellStylesHost, IOperationFeedbackProvider, IDisposable

Remarks

A GridModel holds all data for a grid. It offers many events that you can subscribe to and modify the default behavior of the grid. A GridModel holds a GridCellModelCollection that holds models for all cell types used in the grid. If a cell queries for a new cell type that is not found in the cell model collection, it tries to instantiate a GridCellModelBase object for the specific cell type. A QueryCellModel event is raised to allow you to create custom cell types on demand. But you can also instantiate cell models for custom cell types at initialization and add them to CellModels.

There is also a GridControl class that combines both GridModel and GridControlBase into one class. This gives you easier access to all methods of GridModel.

Constructors

GridModel()

Initializes a new GridModel.

Declaration

public GridModel()
