Go Up to Using data controls Index


A Vcl.DBCGrids.TDBCtrlGrid control displays multiple fields in multiple records in a tabular grid format. Each cell in a grid displays multiple fields from a single row.

To use a database control grid

  1. Place a database control grid on a form.
  2. Set the DataSource property of the grid to the name of a data source.
  3. Place individual data controls within the design cell for the grid. The design cell for the grid is the top or leftmost cell in the grid, and is the only cell into which you can place other controls.
  4. Set the DataField property for each data control to the name of a field. The data source for these data controls is already set to the data source of the database control grid.
  5. Arrange the controls within the cell as desired.

When you compile and run an application containing a database control grid, the arrangement of data controls you set in the design cell at run time is replicated in each cell of the grid. Each cell displays a different record in a dataset.
