public enum SummaryUIType : System.Enum
Member | Description |
---|---|
Default | Default is resolved to MultiSelectForNumericsOnly. |
MultiSelect | User is allowed to add multiple summaries per field. |
MultiSelectForNumericsOnly | Same as SingleSelectForNumericsOnly except this option will allow multiple summaries per field. |
SingleSelect | User is allowed to add only one summary per field via the UI. Note that this does not prevent adding multiple summaries per field via code. |
SingleSelectForNumericsOnly | This option will enable the summaries UI for numeric columns only. For data types such as String or DateTime only a limited subset of summaries are valid like Minimum, Maximum etc. Summaries such as Average, Sum etc… are not applicable to them. This option is a way to only display summaries UI for fields that are numeric types. |
SummaryUIType is used for specifying FieldSettings.SummaryUIType property. To actually enable the user interface, set the FieldSettings.AllowSummaries property.
Private Sub Window1_Loaded(ByVal sender As Object, ByVal e As RoutedEventArgs) ' Set the data source. _dp.DataSource = _dataSource ' AllowSummaries enables the UI for the user to be able to select/unselect ' summaries for fields. SummaryUIType specifies whether the user is allowed to ' select single or multiple summaries pereach field. It also has options for ' enabling summary selection UI for numeric fields only or for all fields. ' _dp.FieldSettings.AllowSummaries = True _dp.FieldSettings.SummaryUIType = SummaryUIType.MultiSelect ' To add a summary, use the SummaryDefinitions property of the FieldLayout. ' Each SummaryDefinition object represents a summary calculation to perform ' on a field's data. SourceFieldName specifies the field whose data will be ' summarized. Key is optional and it simply associates an identifier to the ' summary. This identifier can be used later to access the summary via ' indexers of SummaryDefinitionCollection and SummaryResultCollection. ' Calculator specifies the type of calculation to perform on the field data. ' There are five built in calculators of Average, Sum, Minimum, Maximum and ' Count. However you can easily add custom calculators by deriving from ' SummaryCalculator base class and registering the new calculator using the ' SummaryCalculator's Register static method. ' Dim summaryDef1 As SummaryDefinition = _dp.FieldLayouts(0).SummaryDefinitions.Add( _ "PriceAverage", SummaryCalculator.Average, "Price") ' StringFormat specifies the format that will be used to format the summary ' result. ' summaryDef1.StringFormat = "Avg={0:C}" ' Add a second summary. Dim summaryDef2 As SummaryDefinition = _dp.FieldLayouts(0).SummaryDefinitions.Add( _ "PriceTotal", SummaryCalculator.Sum, "Price") summaryDef2.StringFormat = "Total={0:C}" End Sub
