StringFormat Property
See Also  Example
Infragistics.Windows.DataPresenter Namespace > SummaryDefinition Class : StringFormat Property

Specifies the format to use to when displaying the summary result's value.

Syntax

Visual Basic (Declaration) 
Public Property StringFormat As String
C# 
public string StringFormat {get; set;}

Remarks

StringFormat specifies the format to use when displaying the summary result's value. The resulting value is returned by the SummaryResult's SummaryResult.DisplayText property.

String format is used with the String.Format method to format the summary value. This lets you specify any arbitrary text inside the format. String.Format method is called with summary result's value, sumamry calculator name (Sum, Average etc...), summary definition's key, and the source field name as parameters. This means that you can refer to any of these values inside the format you specify using {0}, {1}, {2} and {3} respectively.

The default value of this property is "{1} = {0}".

Example

The following code demonstrates the usage of SummaryDefinition's StringFormat and StringFormatProvider properties and also the Field's SummaryStringFormats property.

    Private Sub Window1_Loaded(ByVal sender As Object, ByVal e As RoutedEventArgs)
        _dp.DataSource = _dataSource

        Dim fieldLayout As FieldLayout = _dp.FieldLayouts(0)

        Dim summary As SummaryDefinition = fieldLayout.SummaryDefinitions.Add(SummaryCalculator.Sum, "Price")

        ' StringFormat property's value is used to format the summary result using String's Format
        ' method. See .NET String.Format method for more information on available formatting options.
        summary.StringFormat = "Sum={0:C}"

        ' You can also specify a string format provider to use for the summary result.
        summary.StringFormatProvider = System.Globalization.CultureInfo.GetCultureInfo("fr-FR")

        ' Also note that SummaryStringFormats property of the Field can be used to control the format
        ' that gets assigned to summaries that the user selectes via the user interface (summary icon
        ' on the field label). This is in the format of "calculator_name1: format1, calculator_name2: format2".

            "sum: TOTAL={0:c}, average: AVG={0:c}, count: COUNT={0}, minimum: MIN={0:c}, maximum: MAX={0:c}"
