Transition Control to Change the user control after some time interval

[Nikhil]

Hi,

I have 2 Silverlight user controls added in the page. i want to show them at the same place in the page. like at start control1 will be displayed and after some time Control1 will be collapse and control 2 will be displayed. For transition purpose i am want to use Rad Transition control. I tried to do that but somewhere i am failing to add those controls to Transition control.
Could you please help me.

Hi Nikhil,

I would suggest you to check this blog. There is a demo attached to it, so you can examine it. You can place whatever elements you need into the <adRotator:AdsCollection> tag from the demo, for example:

<adRotator:AdsCollection>
    <Button Content="1" Width="60" Height="60"/>
    <Button Content="2" Width="60" Height="60"/>
    <Button Content="3" Width="60" Height="60"/>
    <Button Content="4" Width="60" Height="60"/>
</adRotator:AdsCollection>

Hope this helps.

Hi Nikhil,

I used this AdCollection class that you mentioned below and it works like a charm!

Now...I have a collection of UserControls (views) that I am using the Transition Control to cycle through. They are defined as such:

<telerik:RadTransitionControl x:Name="radTranstionControl"
              chartExtensions:ChartRotatorExtensions.ItemChangeDelay="0:0:20"
              chartExtensions:ChartRotatorExtensions.CurrentSelectedIndex="0"
              VerticalAlignment="Center" HorizontalAlignment="Center">
            <telerik:RadTransitionControl.Easing>
                <BackEase EasingMode="EaseInOut" Amplitude="1" />
            </telerik:RadTransitionControl.Easing>
            <telerik:RadTransitionControl.Transition>
                <telerikTransitions:PixelateTransition />
            </telerik:RadTransitionControl.Transition>
            <chartExtensions:ChartRotatorExtensions.ItemsSource>
                <chartExtensions:ChartsCollection>
                    <RadChartViews:PriorityTicketView />
                    <RadChartViews:TotalElapsedOpenTicketsView />
                </chartExtensions:ChartsCollection>
            </chartExtensions:ChartRotatorExtensions.ItemsSource>
        </telerik:RadTransitionControl>

You can see my views being added to the ChartsCollection object. These views contain RadCharts. If you want me to post this to the RadChart forum, I will. But since this has to do with a subject found here (and I am using the Transition Control), I posted it here.

Anyway, my problem is these views get instantiated in order to put them into the collection. When you cycle through, the first chart displays fine. All subsequent charts display default data only regardless of how I programmatically create and databind them.

My question is, what is the best way to see if a RadChart has been simply created (i.e. new RadChart() ) and contains dummy data or if it has real data in it?

Hello,

RadChart does not display default data, so if a chart displays any data, it has been populated. You can peek the value of RadChart.DefaultView.ChartArea.DataSeries in order to check what data is currently displayed by the chart, but the bottom line is that if RadChart displays data, it has been put there.

All the best, Ivo
