Hello Shahab,
Thank you for your interest in RadCarousel control.
You should use the properties
ButtonPrevious and
ButtonNext that represent the buttons that move the items forward and backward.
For example:
public Form1()
{
InitializeComponent();
this.radCarousel1.ButtonNext.Image = Image.FromFile("MyImage.bmp");
...
I hope this helps.
Don't hesitate to contact us if you have other questions.
All the best,
