Hello everyone,

I would like to know how their support to put a control on the usercontrol RadCarousel, check the forum and no one to touch this topic. I hope they can give me some suggestion.

Right now I have this:

My main window called Window1.xaml, Radcarosel'm in control here.
My usercontrol called UserControl1.xaml.

What I need is to put the usercontrol in Radcasucel

Hi,

Hi everybody.

I need a suggestion on this issue: I got an object list that I use as itemssource for Carousel. Those objects inside list includes some strings and the image, which comes from a query that, unfortunately, takes very long time due to dimension of images.

The only way to make it faster is to remove image field from the output of the query and set it to null: in this way, obviously, my carouselitems will be without photo.

Now, how can I manage an event (e.g. Click) inside the elements  of my ControlTemplate of my corouselItem? I would like to have something like a "deferred image loading", so the user will see many carouselItem without photo, but when he clicks on the item inside the eventhandler a single specific query will be done for only the image selected (so faster).

I made carouselItem following telerik sample code:

<Setter Property="Width" Value="500" />

I upgraded to the latest 2010 WPF RadCharts and the custom colors for the series are not displayed anymore.  I was doing this for a pie chart and a bar chart that needed specific green and red colors.  Now it displays what I assume is the default colors.  Here is the style for the pie chart, it is similar for the bar chart.  How do I get this to work with the new Charting. 

No documentation for TransitionControl, no for WPF, no for Silverlight etc??? How do you think we can use it?

Hi,

I'm looking at my application and the QSF demos, and am seeing a similar thing happening with RadCarousel.  When you scroll into selection the item on either side of a RadCarousel, it correctly looks focused and selected.  However, on either end of the RadCarousel, you can scroll beyond the last item.  On the Carousel/First Look demo (WPF Q1 2009 SP2), you can scroll three extra notches to the left of "Ann Devon" and three extra notches to the right of "Ana Trujillo."  Thus it seems like there are six "ghost items" in the carousel.  I'm sure you have noticed this, since it is in the QSF itself.  However, I'm wondering, is there any way to disable this in my own RadCarousel (a property or something)?  Personally I think it looks a little weird to be able to scroll past either end of the list of items.  I'd love it if anybody could help me out getting rid of these ghost items!

Also, there's a bit of a quirk with these ghost items - I'm looking again at the Carousel/First Look example.  When an extrememost item is selected (in this case, Ann Devon or Ana Trujillo) by (single or double) clicking on it, scroll out into the ghost items.  You now cannot double click the extrememost item to bring that item in front and in focus.  Now scroll back and (single/double) click on either Georg Pipps or Christina Berglund to bring them front and center.  Now, without clicking on other items (i.e., use the scroll wheel on the mouse or the scroll buttons on the carousel), scroll out to the ghost items (this is, of course, the only way to scroll out into the ghost items, using the mouse or the buttons).  You will now be able to double click on one of the extrememost items and zoom back into the regular items list.  Sorry if my instructions to replicate this are a little foggy... you may need to scroll as far left or as far right into the ghost items as possible in order to see these effects.  However, even if this is a little unclear, it is totally happening every time on my machine and is just a little bit of a bug I think.  I hope it's not just me! :)

Thanks,

In trying out the WPF stuffs, I've noticed there a string for TransitionControl.Transition, instead of enumeration.  Why?
And, what are the acceptable values.

1) Is there a way to have the currentcell enter edit mode when the user starts typing input?

2) Is there a way to move to the next column when the user presses enter?

I want to download trial version of WPF Rad Controls. I find that it takes long time (more than an hour) and in the end hangs.
Finally am not able to download the trial software.
Any suggestions??

I have a RadPane blocking the correct compass, so instead of docking to a higher level, my window becomes a peer to the RadPane within the RadPane to which I want to dock.
