Public Overridable Property DataTextFormatString As String

Property Value

The formatting string for data bound to the control. The default value is Empty.



Use the DataTextFormatString property to provide a custom display format the items in a list control.

The data format string consists of two parts, separated by a colon, in the form { A : Bxx }. For example, the formatting string {0:F2} would format the cell to display a fixed point number with two decimal places.


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.


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.


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 following table contains examples of formatting strings and the results. It assumes standard English settings.
