WasMaxSelectedDaysExceeded Property

Indicates if the max selected items would have been exceeded by the selection change.

Syntax

Visual Basic

'Declaration
 
Public ReadOnly Property WasMaxSelectedDaysExceeded As Boolean

C#

public bool WasMaxSelectedDaysExceeded {get;}

Property Value

Returns true if the UltraCalendarInfo.MaxSelectedDays property was exceeded during the selection operation.

Example

This example uses the BeforeSelectedDateRangeChangeEventArgs' WasMaxSelectedDaysExceeded property to determine if the limit on selected days has been reached if it has, the limit is incremented. It also checks the new selection to determine whether the selection includes a weekend day and if it does, the user is prompted.
