Hi,

I'm working on a WPF application which include RadCarousel component (Telerik V2010.3.1314.35). I have some questions about the component. In my RadCarousel, I have multiple images.

1. Actually, I'm trying to know if the click made by the user in the RadCarousel was on the top image or not. If the click was on the top image, I will bring him another RadCarousel full screen with the top image and maybe all associated images ortherwise I will keep the normal behavior.

2. Actually, all existing images in my RadCarousel are not aligned horizontally, all of them are aligned on a "3/4 of a circle line". The problem I have actually is when I bring up a full screen RadCarousel to my users, I'm trying to center the selected image and use the maximum height possible to display the selected image. Because I have the horizonal scroll panel of my RadCarousel visible, which is necessary, plus the fact that my image is centered on the "3/4 of the circle line", I lost spaces to display my image. How I can fix it???

Thank`s

Hello Oliver,

The topmost item is the TopContainer - you may get it like follows:

CarouselItem topmostItem = this.myCarousel.FindCarouselPanel().TopContainer as CarouselItem;

Consequently, you may verify whether the clicked item is the top container. 
Considering your second issue, if you want the path of the carousel to be a horizontal one, you may follow the approach illustrated in this forum thread.
Let me know in case you need any further assistance.

Hi,

If I understand, TopContainer alway return the top most z-index items???

Regarding this, can you explain the difference between, CurrentItem, SelectedItem and TopContainer???
Can you tell me if MoveBy, changing CurrentItem/SelectedItem should altered TopContainer content???

Hi Oliver,

Indeed, the TopContainer is the carousel item with the biggest Z-index. The SelectedItem is the data item of the selected carousel item, while the CurrentItem is the one that holds the focus. The later may or may not coincide with the first one. 
Executing the MoveBy(int value) method will change the TopContainer item, but not the selected one.

Ok nice,

I guest, to force SelectedItem to be equal to the item in top container, I just have to do something like this: SelectedItem = TopContainer.Object

Hello Oliver,

I have tested the sample project in this forum thread and it seems to work correct. May you take a look at this small video illustrating the behavior on my side ? Is it different at yours ?

Hi,

the reverse problem occured when I don't use the "Path" parameter, I'm sorry... :(

Without the "Path" parameter, if I click on the left scrolling button of the carousel navigation bar, the image start scrolling
from left to right... If I use the "Path" parameter and I click on the carousel navigation bar, the image start scrolling
from right to left.

BTW, can you tell me if you have DETAILED help file about Telerik components??? Actually, in VS when I get throught the help of PATH property, I see: Gets or sets the carousel path
So, in this situation, I don't even know what I can use as a values for this propertiy ;)

Thank's

Hello Oliver,

You may run through our online documentation and demos considering examples of RadCarousel and RadCarouselPanel. Furthermore, you may look at our forums as well. However, if this is not enough and you feel there should be articles that need to be added in our documentation or examples, please do not hesitate to share your feedback.
As for setting the path property, the movement direction depends on the defined start and end points of the path. Here is the place to apologize as I picked up a wrong example to simulate the issue you reported. The FirstLook example has a specific path set through the CreateLinePath() method. The default path is the one that you see at the mentioned sample project without setting the Path property. 
If you want to change the direction of the HorizontalPath, you can change the places of the numbers in the Data property. 

 

All the best,

Hi Shameel,

Will it be possible to clarify what your exact issue is? Do you get wrong scrolling directly with the default path of RadCarouselPanel?

Hi Maya,

I solved my issue using the Path Property, The code is given below..

    <Path x:Key="horizontalPath" Stretch="Fill">
                        <Path.Data>
                            <LineGeometry StartPoint="300,200" EndPoint="20,200" />
                        </Path.Data>
                    </Path>
