| Data Presentation Techniques > Text Formatting > Using Visual Basic's built-in formatting |
True DBGrid supports a variety of data formatting options through the Column object's NumberFormat property, which provides the same functionality as Visual Basic's Format$ function. For example, to display all date values within a column according to the form 26-Apr-97, you would use the Medium Date setting:
| Example Title |
Copy Code
|
|---|---|
TDBGrid1.Columns("HireDate").NumberFormat = "Medium Date" |
|
Note that if you change the NumberFormat property of a column at run time, you do not need to refresh the display, as True DBGrid handles this automatically.
At design time, you can set the NumberFormat property using the Columns property page. For numeric data, the following predefined options are available:
|
Standard |
Display number with thousands separator, at least one digit to the left and two digits to the right of the decimal separator. |
|
General Number |
Display number as is, with no thousand separators. |
|
Currency |
Display number with thousand separator, if appropriate; display two digits to the right of the decimal separator. Note that output is based on system locale settings. |
|
Percent |
Display number multiplied by 100 with a percent sign (%) appended to the right; always display two digits to the right of the decimal separator. |
|
Fixed |
Display at least one digit to the left and two digits to the right of the decimal separator. |
|
Scientific |
Use standard scientific notation. |
|
Yes/No |
Display No if number is 0; otherwise, display Yes. |
|
True/False |
Display False if number is 0; otherwise, display True. |
|
On/Off |
Display Off if number is 0; otherwise, display On. |
|
0% |
Display number multiplied by 100, then rounded to the nearest integer, with a percent sign (%) appended to the right. |
|
0.00% |
Same as Percent. |
For date and time data, the following predefined options are available:
|
General Date |
Display a date and/or time. For real numbers, display a date and time (for example, 4/3/93 05:34 PM); if there is no fractional part, display only a date (for example, 4/3/93); if there is no integer part, display only a time (for example, 05:34 PM). Date display is determined by your system settings. |
|
Long Date |
Display a date using your system's long date format. |
|
Medium Date |
Display a date using the medium date format appropriate for the language version of Visual Basic. |
|
Short Date |
Display a date using your system's short date format. |
|
Long Time |
Display a time using your system's long time format: includes hours, minutes, seconds. |
|
Medium Time |
Display a time in 12-hour format using hours and minutes and the AM/PM designator. |
|
Short Time |
Display a time using the 24-hour format (for example, 17:45). |
