Differences between the DataGridView and DataGrid controls
The DataGridView control provides numerous basic and advanced features that are missing
in the DataGrid control. Additionally, the architecture of the DataGridView control
makes it much easier to extend and customize than the DataGrid control.
Multiple column types
The DataGridView control provides more built-in column types than the DataGrid control.
These column types meet the needs of most common scenarios, but are also easier
to extend or replace than the column types in the DataGrid control.
Multiple ways to display data
The DataGrid control is limited to displaying data from an external data source.
The DataGridView control, however, can display unbound data stored in the control,
data from a bound data source, or bound and unbound data together. You can also
implement virtual mode in the DataGridView control to provide custom data management.
Multiple ways to customize the display of data
The DataGridView control provides many properties and events that enable you to specify
how data is formatted and displayed. For example, you can change the appearance
of cells, rows, and columns depending on the data they contain, or you can replace
data of one data type with equivalent data of another type.
Multiple options for changing cell, row, column, and header appearance and behavior
The DataGridView control enables you to work with individual grid components in numerous
ways. For example, you can freeze rows and columns to prevent them from scrolling;
hide rows, columns, and headers; change the way row, column, and header sizes
are adjusted; change the way users make selections; and provide ToolTips and
shortcut menus for individual cells, rows, and columns.
The only feature that is available in the DataGrid control that is not available
in the DataGridView control is the hierarchical display of information from two
related tables in a single control. You must use two DataGridView controls to
display information from two tables that are in a master/detail relationship.
