    ...

The ClientInstanceName property is important when a control is contained within a naming container, for instance, within an ASPxPageControl‘s page or an ASPxPopupControl‘s window.

If the ClientInstanceName property is not specified for a control, the control’s client identifier is generated automatically and equals the value of the control’s System.Web.UI.Control.ID property. Note that in this case, client-side programmatic access to the control is not allowed when the control is contained within a naming container.
