KeyMember Property (OwnersDataBinding)

Gets/sets the field to use to initialize the owner’s Key property when bound.
Syntax
'Declaration
 
Public Property KeyMember As String
public string KeyMember {get; set;}
Example
The following code creates a Datatable with the proper schema to bind to the Owners collection of an UltraCalendarInfo and then sets all the appropriate bindings.

#Region " CreateOwnersDataTable"
    Private Function CreateOwnersDataTable() As DataTable
        Dim newTable As New DataTable()

        'Basic Owner properties
        ' In order to function properly, the table must contain data for 
        ' the Owners Key. Keys are required for an Owner. 
        newTable.Columns.Add("Key", GetType(String))
        newTable.Columns("Key").Unique = true

        'Other Owner properties
        newTable.Columns.Add("Name", GetType(String))
        newTable.Columns.Add("EmailAddress", GetType(String))
        newTable.Columns.Add("Visible", GetType(Boolean))

        'Unlike Appointments, the Owner properties are all covered by 
        'individual members. But we could save space in the database by storing
        'data as binary imports AllProperties and not binding the other fields. 
        newTable.Columns.Add("AllProperties", GetType(Byte()))
        Return newTable
    End Function

#End Region
