Syntax
public class CaptionSection : RowElementsSection, IDisposable, IDisposedEvent, IIsDisposedProperty, ITreeTableCounterSource, ITreeTableSummaryArraySource, IRowElementsContainer, IContainerElement, IElementTreeTableSource, IElement
Remarks

This is the first section within a group which provides the caption bar above the column headers. CaptionSection is a display element and will be an item returned by the Table.DisplayElements and Table.GroupedElements collection.

CaptionSection is also a section that can be accessed through the Group.Sections collection of its parent group.

If a caption should be displayed at the beginning of each group, then CaptionSection (s) are created when the grouping for a table is initialized. The grouping engine loops through all sorted records and categorizes them. For each new group, the virtual TableDescriptor.CreateGroup factory method is called. The TableDescriptor.CreateGroup method instantiates a CaptionSection by calling the virtual TableDescriptor.CreateCaptionSection factory method.

Examples

The following example creates a string based on the CaptionSection's parent Group number of direct child elements (as usually shown in the caption element for a group in GroupingGrid). Use the ParentGroup property to get access to the parent Group of this CaptionSection:

            CaptionSection cs;
            object cat = cs.ParentGroup.Category;
            if (cat == null)
                cat = "(null)";
            string caption = "{2} Item(s)";
            string groupName = cs.ParentGroup.Name;
            if (groupName != "")
                caption = "{0}: {1} - " + caption;
            return string.Format(caption, groupName, cat, cs.ParentGroup.GetChildCount());
