[YING JANG LIN]

Hi,

below is my code is add item to carousel

        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.

Thanks

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.

Hi,Peter

thanks your help.

Below is exact code worked for this question and shared to other.

Private Sub RadCarousel1_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles RadCarousel1.SelectedIndexChanged
        Dim selectedButton As RadButtonElement
        selectedButton = CType(Me.RadCarousel1.SelectedItem, RadButtonElement)
        MessageBox.Show(selectedButton.Text)
End Sub

1,another question is code add to Sub RadCarousel1_SelectedItemChanged cann't work That Hope you can tell me what?
2,When Clicked button_next also fire RadCarousel1_SelectedIndexChanged,you can see hardcopy screen at attach file?
3,I hope program run like Telerik run demo Integration section function?

Thanks Peter

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,Peter

I hope get hardcopy of attached file of sample code in Vb.net,
Those samples are satisifiable demand for me.


Thanks

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,
