Xceed DataGrid for WPF v7.2 Documentation
Convert Method (StatResultConverter)


Xceed.Wpf.DataGrid Assembly > Xceed.Wpf.DataGrid.Converters Namespace > StatResultConverter Class : Convert Method
The result of a statistical function.
The target type is ignored by the StatResultConverter.

A composite format string. If a FormatProvider has been provided, it will be used in combination with the format string to convert the value (see also Composite Formatting topic in Windows SDK).

If parameter is a null reference (Nothing in Visual Basic), value will be returned unmodified.

Composite format strings use braces ("{}") to identify place-holders, which causes an issue when providing a format string to a StatResultConverter in XAML; therefore, the StatResultConverter supports square brackets ("[]") as a substitute for braces. For example, if normally {0:#0.0} would have been used, it would be replaced with [#0.0] when using a StatResultConverter. If braces are preferred, the format string must be preceded with a closing brace (e.g., ConverterParameter={}{0:#0.0}}).

When using square brackets, the 0: that represents the place-holder must be omitted otherwise an exception will be thrown.
The culture info is ignored by the StatResultConverter.
Converts the specified value using the composite format string specified as parameter.

Remarks

The messages returned by a StatResultConverter when an exception occurs during the calculation of a statistical function's result depend on the type of the exception that was thrown. The following table provides a list of exceptions for which default messages have been provided: 

Exception Default message
DivideByZeroException #DIV/0#
Exception #[Exception.Message]#
InvalidSourcePropertyNameException #[InvalidSourcePropertyNameException.SourcePropertyName]#
InvalidValueException #VALUE#
OverflowException #OVER#
