Placement Modes in Xamarin Rotator (SfRotator)

11 Aug 20225 minutes to read

By default, the rotator control displays the dots of each rotator item. It can be changed to any of the following types:

• Default
• None
• Outside

DotsPlacement

The Display Type of Rotator can be modified using the DotsPlacement Mode. The “None” type can be used when the dots are not needed for the rotator control.
