Using the TDBGrid Component

DBGrid to the Max

Contrary to most other Delphi data-aware controls, the DBGrid component has many nice features and is more powerful than you might think.

Below are ways in which you can get the most out of the TDBGrid Delphi component, separated into categories.

The Basics

You can make the Enter key work like the Tab key in a DBGrid, which also allows Shift+Enter to function like it would if Tab+Enter were used.

See how to fix DBGrid column widths automatically (at run-time) to remove the unfilled space at the right edge of the grid.

It will automatically adjust the column width to fit even the widest entry.

You can also enhance the functionality of a TDBgrid component using colors (coloring rows, columns, cells - depending on a field value).

Some Other Nifty Tutorials

When the DBGrid's Options property includes dgRowSelect and dgMultiSelect, users can select multiple rows within the grid.

One of the most natural and easiest ways to let your users sort a column is to have them click the column title. Follow our guide on how to sort records in Delphi DBGrid for all the information you need to make this happen.
