    Inherits TabbedGroup

The following members return TabbedControlGroup objects:

Remarks

A tabbed group is visually represented by tabbed pages, each of which displays a regular group (a LayoutControlGroup object). Thus, a tabbed group is a container of LayoutControlGroup objects. To access the tabbed group’s child groups, use the TabbedControlGroup.TabPages property. To add tabs to the tabbed group, use the TabbedGroup.AddTabPage method.

The text displayed within a tabbed page header is specified by the BaseLayoutItem.Text property of the corresponding LayoutControlGroup group.

The following image shows a form which contains a layout control. The root group displays two regular layout items (Job Title and Contact Name), regular group (Personal Info) and tabbed group. The tabbed group contains two tabs which display two groups (Photo and Notes):

TabbedGroup_structure

A tabbed group can be created as follows:

via the LayoutControlGroup.AddTabbedGroup method. In this case, the created group is automatically added to the current group..
via the group’s constructor. The new group can then be added to another group via the LayoutGroup.Add or LayoutGroup.Move method.

Example

The following example shows how to create a tabbed group that contains two pages. The first page will display a group with a layout item that contains a PictureEdit editor.

A tabbed group is created using the LayoutControlGroup.AddTabbedGroup method of the root group. Tabs are added via the TabbedGroup.AddTabPage method.

The following image shows the result:
