Gets or sets the string that specifies the display format for items in the column.
[Visual Basic]
Overridable Public Property DataFormatString As String
[C#]
public virtual string DataFormatString {get; set;}
[C++]
public: __property virtual String* get_DataFormatString();
public: __property virtual void set_DataFormatString(String*);
[JScript]
public function get DataFormatString() : String;
public function set DataFormatString(String);
Property Value
A formatting string that specifies the display format of items in the column. The default value is String.Empty.
Remarks
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:D2}, would format the cell to display a number with two decimal places.
Note The entire string must be enclosed in curly braces to denote that it is a format string and not a literal string. Any text outside the curly 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 the value in.
For more information on formatting strings, see Formatting Overview.
