This example shows the Fields Customization Window. This allows you to temporarily hide
specific fields and then restore them again when needed.
ASPxPivotGrid allows you to show and hide the Fields Customization Window both on the server (using C# or VB code)
btnCustomizationFields button, we are calling the ChangeCustomizationFieldsVisibility() function which hides or
shows the Fields Customization Window.
The ChangeCustomizationFieldsVisibility function is a part of the ASPxPivotGrid's ClientSideAPI.
The ClientSideAPI is a collection of functions and events available on the client.
These functions are disabled by default. To turn them on, set the EnableClientSideAPI property value to true.
Also, the demo shows the usage of the ClientSide CustomizationFieldsVisibleChanged event.
When fired, this event changes the btnCustomizationFields button caption from "Show" to "Hide" and
vice versa. This event is available only when the EnableClientSideAPI property is true.
