You can give your end users the ability to select the row summaries for a field in xamDataPresenter™ by setting the AllowSummaries property of a FieldSettings object to True. When you set the AllowSummaries property to True, xamDataPresenter will display a summary button in the field labels. Your end users can click the summary button to display a summary selection dialog box. In the summary selection dialog box, they can select the row summaries they want to see. You can manually add summaries for a field using XAML or procedural code even if you do not set the AllowSummaries property to True.
In addition to the AllowSummaries property of a FieldSettings object, you can also use the following properties to modify summary related behaviors:
SummaryDisplayArea - This property determines the location where XamDataPresenter displays the summary results.
SummaryUIType - This property determines whether an end user can select a single summary or multiple summaries for a field. The default value for this property is MultiSelectForNumericsOnly. If you want to enable summaries for non-numeric fields, you have to set this property to either SingleSelect or MultiSelect.
You can set the summary related properties on xamDataPresenter’s FieldSettings property and/or on a Field object’s FieldSettings property. Any summary related property that you explicitly set on a field level will override the corresponding summary related property that you set on the xamDataPresenter control level.
The following example code demonstrates how to enable row summaries.
In XAML:
...
<igDP:XamDataPresenter Name="xamDataPresenter1" BindToSampleData="True">
<igDP:XamDataPresenter.FieldSettings>
<igDP:FieldSettings
AllowSummaries="True"
SummaryUIType="MultiSelect"
SummaryDisplayArea="InGroupByRecords, BottomFixed" />
</igDP:XamDataPresenter.FieldSettings>
</igDP:XamDataPresenter>
...
In Visual Basic:
Imports Infragistics.Windows.DataPresenter ... Me.xamDataPresenter1.FieldSettings.AllowSummaries = True Me.xamDataPresenter1.FieldSettings.SummaryUIType = SummaryUIType.MultiSelect Me.xamDataPresenter1.FieldSettings.SummaryDisplayArea = SummaryDisplayAreas.InGroupByRecords Or SummaryDisplayAreas.BottomFixed ...
In C#:
using Infragistics.Windows.DataPresenter; ... this.xamDataPresenter1.FieldSettings.AllowSummaries = true; this.xamDataPresenter1.FieldSettings.SummaryUIType = SummaryUIType.MultiSelect; this.xamDataPresenter1.FieldSettings.SummaryDisplayArea = SummaryDisplayAreas.InGroupByRecords | SummaryDisplayAreas.BottomFixed; ...
