The System.Web.UI.Design.ControlDesigner class, and any derived class, defines the ControlDesigner.TemplateGroups property as a System.Web.UI.Design.TemplateGroupCollection object. The System.Web.UI.Design.TemplateGroupCollection property is typically used only by a design host such as vsprvslong.

The collection dynamically increases in size as objects are added. Indexes in this collection are zero-based. Use the TemplateGroupCollection.Count property to determine how many groups are in the collection.

Additionally, use the System.Web.UI.Design.TemplateGroupCollection methods and properties to provide the following functionality:

• The TemplateGroupCollection.Add(TemplateGroup) method to add a single group to the collection.

• The TemplateGroupCollection.Insert(int, TemplateGroup) method to add a group at a particular index within the collection.

• The TemplateGroupCollection.Remove(TemplateGroup) method to remove a group.

• The TemplateGroupCollection.RemoveAt(int) method to remove the group at a particular index.

• The TemplateGroupCollection.Contains(TemplateGroup) method to determine whether a particular group is already in the collection.

• The TemplateGroupCollection.IndexOf(TemplateGroup) method to retrieve the index of a group within the collection.

• The TemplateGroupCollection.Item(int) indexer to get or set the group at a particular index, using array notation.

• The TemplateGroupCollection.AddRange(TemplateGroupCollection) method to add multiple groups to the collection.

  You can add multiple groups either as an array of groups or as a System.Web.UI.Design.TemplateGroupCollection object that you retrieve through the ControlDesigner.TemplateGroups property of another control designer.

• The TemplateGroupCollection.Clear method to remove all groups from the collection.
