'Declaration
 
Public Property DataIndex As Integer

'Usage
 
Dim instance As GridColumn
Dim value As Integer
 
instance.DataIndex = value
 
value = instance.DataIndex

public int DataIndex {get; set;}

public: __property int get_DataIndex();
public: __property void set_DataIndex( 
   int value
);

public:
property int DataIndex {
   int get();
   void set (    int value);
}

Data index identifies the data displayed in a column. When you set a data index you actually define a scheme for your grid.
For example you need to display the following data structure in the grid:
{Name, Age, E-mail}
and you add appropriate columns to the Grid control.
Records represented by GridDataRow are collections of GridDataItem objects.
DataIndex specifies an index in this collection:

GridColumn colName = new GridColumn ();
colName.DataIndex = 0;

GridColumn colAge = new GridColumn ();
colAge.DataIndex = 1;

GridColumn colEmail = new GridColumn ();
colEmail.DataIndex = 2;

Now the order of columns in GridControl.ColumnCollection is not important, because the data for our columns can be retrieved using DataIndex.
