Data can be stored and displayed in two ways with Objective Grid for Microsoft .NET GridControl objects:

• First, the GridControl properties RowCount and ColCount and the GridControl methods SetStyleRange and SetValueRange can be used to set the size of the grid and to store data directly to the grid.

  With this method, the grid data is stored directly in the GridControl's parameter object. The size and content of the grid is managed entirely by the GridControl and its parameter object.

• Second, the GetStyleRowCol and StoreStyleRowCol events can be used to store and retrieve grid data from your own data structure or structures.

  With this method, you are responsible for managing, to some degree, the size and content of the grid.

For Objective Grid for Microsoft .NET, "Virtual Grid" refers to the second use case (or some hybrid of both use cases).
