Use the ClientInstanceName property to specify a unique client-side identifier for a scheduler control. The ClientInstanceName property's value can be used on the client side to programmatically access the client object rendered for the scheduler in client-side script. This property is particularly important in referencing the scheduler when it is contained within a naming container (for instance, within an ASPxPageControl's page).
If the ClientInstanceName property is not specified, a scheduler's client identifier is generated automatically, and equals the value of the scheduler's System.Web.UI.Control.ID property. Note that in this case, client-side programmatic access to the scheduler by its ID is not allowed when it is contained within a naming container.
