Question

I’m using the RadContinuumAnimation from Telerik inside of my Windows Phone 7 application on a listbox. Now when you get the controls the do give an example which you can download from telerik on how to use it but they hardcode it so it only lets you select the first item.

Ironically when I used it on my listbox in my application it allowed me to select an item in my listbox and it behaved properly but everytime the animation took place it ALWAYS animates the first item.

I found this post in Telerik forums, but I haven’t been able to make much out of it. I tried the setting the ContinuumElement to the SelectedItem but it threw this error:

‘MyApp_2011.Model.MenuItem’ is not a valid value for property ‘ContinuumElement’.

I’m guessing that it has to be a control such as a Textblock but I’m not sure how to access the textblock since the listbox is databound. Does someone with more experience understand why this might be happening or how to solve this?

Answer 1

I think you basically need to do this

if (!(this.continuumElement is TextBlock)) 
            { 
                TextBlock textBlock = ElementTreeHelper.FindVisualDescendant<TextBlock>(this.continuumElement); 

                if (textBlock != null) 
                { 
                    this.continuumElement = textBlock; 
                } 
            }

In your ListBox‘s SelectionChanged event.

private void YourListBox_SelectionChanged(object sender, SelectionChangedEventArgs e)
{
}
