          RadCarousel1.Items.Add(ButtonBox1)
          RadCarousel1.Items.Add(ButtonBox2)
          RadCarousel1.Items.Add(ButtonBox3)
          RadCarousel1.Items.Add(ButtonBox4)
  
  Then, my question is
  
  1,How to catch which above button is click in below  subroutin ,
  
  

  Private Sub RadCarousel1_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles RadCarousel1.SelectedIndexChanged
              

      End Sub
  
  2, mouse over item can change mouse icon to hand that item move to path of specific position whcih predefine.
   
  Hope you can me.

  Hi YING JANG LIN,
   
  You can get the selected button using the Carousel's SelectedItem in RadCarousel1_SelectedIndexChanged:
   
  

  me.radCarousel1.SelectedItem

  
  About the second question you can change the mouse cursor using each Carousel item button's events MouseHover and MouseLeave. Refer to the code below:
   
  

  AddHandler buttonBox1.MouseHover, AddressOf imageItem_MouseHover                AddHandler buttonBox1.MouseLeave, AddressOf imageItem_MouseLeave

   

  Private Sub imageItem_MouseLeave(ByVal sender As Object, ByVal e As EventArgs)
Cursor = Cursors.Default       

  End Sub

  Private Sub imageItem_MouseHover(ByVal sender As Object, ByVal e As EventArgs)          

   Cursor = Cursors.Hand       

  End Sub

   
  but you cannot move an item to the specific positions with Drag&Drop, because coordinates for items are evaluated only from RadCarouselCalculator. Please, excuse us for the inconvenience.

  Hi YING JANG LIN,
  
  Thanks for the provided information.
   
  You should cast the SelectedItem to RadButtonElement and show the Text property of the RadButtonElement:
   
  

  Dim selectedButton as RadButtonElement
  selectedButton  = CType(radCarousel.SelectedItem, RadButtonElement)
  MessageBox.Show( selectedButton.Text )
  

  Hope this helps.

  Hello Ying,
  
  The reason that SelectedItemChanged is not working as SelectedIndexChanged is virtualization - this event also fires with non virtualized items, so you can handle SelectedIndexChanged instead of SelectedItemChanged
  
  I cannot find any attached files in your ticket? Can you clarify what do you mean with "run like Telerik run demo Integration section function?" - we do not have any carousel examples in integration section in our example application.

  Hi YING JANG LIN,
  
  This carousel is a custom implementation for our demos only - this implementation is not supported. Please, use RadCarousel instead.
  
  
  All the best,
