public: virtual property String^ DataFormatString { String^ get (); void set (String^ value); }
Property Value
Type: System::StringA formatting string that specifies the display format of items in the column. The default value is String::Empty.
Use the DataFormatString property to provide a custom format for the items in the column.
The data format string consists of two parts, separated by a colon, in the form { A : Bxx }. For example, the formatting string {0:F2} displays a fixed-point number with two decimal places.
Note: |
|---|
The entire string must be enclosed in braces to indicate that it is a format string and not a literal string. Any text outside the braces is displayed as literal text. |
The value before the colon (A in the general example) specifies the parameter index in a zero-based list of parameters.
Note: |
|---|
This value can only be set to 0 because there is only one value in each cell. |
The character after the colon (B in the general example) specifies the format to display the value in. The following table lists the common formats.
Format character | Description |
|---|---|
C | Displays numeric values in currency format. |
D | Displays numeric values in decimal format. |
E | Displays numeric values in scientific (exponential) format. |
F | Displays numeric values in fixed format. |
G | Displays numeric values in general format. |
N | Displays numeric values in number format. |
X | Displays numeric values in hexadecimal format. |
Note: |
|---|
The format character is not case-sensitive, except for X, which displays the hexadecimal characters in the case specified. |
The value after the format character (xx in the general example) specifies the number of significant digits or decimal places to display.
