public virtual void AddRange(
	ReportItemBase[] items
)

Public Overridable Sub AddRange ( 
	items As ReportItemBase()
)

Parameters

items

Type: Telerik.ReportingReportItemBase
An array of ReportItemBase objects to add to the collection.

The ReportItemBase objects contained in the items array are appended to the end of the collection.

You can use the AddRange method to quickly add a group of ReportItemBase objects to the collection instead of manually adding each ReportItemBase to the collection using the Add(T) method.

To remove a ReportItemBase that you previously added, use the Remove(T), RemoveAt(Int32), or Clear methods.
