Applying Styles to Cells

True DBGrid for .NET provides three ways to control the display characteristics of individual cells:

By Status	Each grid cell has a cell status that identifies its disposition (any combination of current, modified, part of a selected row, or part of a highlighted row). Using the AddCellStyle method, set style attributes that apply to any possible combination of cell status values.
By Contents	Specify a pattern (called a regular expression) that is used to perform pattern matching on cell contents. When the contents match the pattern supplied in the AddRegexCellStyle method, True DBGrid will automatically apply pre-selected style attributes to the cell.
By Custom Criteria	Using the FetchCellStyle (or FetchRowStyle) event, make decisions about cell colors and fonts each time a cell (or row) is displayed.

Use Style objects defined at design time as arguments to the AddCellStyle and AddRegexCellStyle methods. Or, create a temporary style in code and use it to specialize one or more attributes.

The FetchCellStyle and FetchRowStyle events pass a temporary Style object as the final parameter. By setting its properties, control the appearance of the cell specified by the other event parameters.

In this version of True DBGrid, per-cell font and color control can only be achieved by writing code. However, by creating styles at design time, this code is kept to a minimum. To learn how to create named styles at design time, see Using the C1TrueDBGrid Style Editor.
