itemheight and itemwidht?

[Lorenzo]

Hello! I'm recently trying to implement a DataboundListbox with wrap mode and reading on the documentation (http://www.telerik.com/help/windows-phone/raddataboundlistbox-features-virtualizationstrategies.html), I should be able set t the ItemHeight and ItemWidht properties when defining StackVirtualizationStrategyDefinition properties.

I have no idea how to implement this behaviour differently!

[Lorenzo]

Uhm, I don't know why, but it seems that iI cut part of the message away.

What i wanted to say is that i can't find the way to set those options while designing in xaml. I attached an example of the behavior.

Hi Lorenzo,

Thank you for contacting us.
The StackVirtualizationStrategyDefinition does not support item width and item height. One way to achieve the result you're looking for would be to do something like this:

<telerik:RadDataBoundListBox x:Name="listBox1" Height="200">
    <telerik:RadDataBoundListBox.ItemContainerStyle>
        <Style TargetType="telerik:RadDataBoundListBoxItem">
            <Setter Property="Width" Value="200" />
            <Setter Property="BorderThickness" Value="2" />
            <Setter Property="BorderBrush" Value="Blue" />
            <Setter Property="Background" Value="Red" />
        </Style>
    </telerik:RadDataBoundListBox.ItemContainerStyle>
    <telerik:RadDataBoundListBox.VirtualizationStrategyDefinition>
        <telerik:StackVirtualizationStrategyDefinition Orientation="Horizontal" />
    </telerik:RadDataBoundListBox.VirtualizationStrategyDefinition>
</telerik:RadDataBoundListBox>

Give it a try and let us know how it goes.

Thanks for the response, it works like a cake! thank you very much.

I have another issue however. It's not connected to the previous issue but i don't want to create too many discussions so i'll keep it here.

I'm trying to implement an ItemAdded animation to the previous, more specifically a RadPlaneProjectionAnimation.

If i use the same exact animation on the Itemremoved event the program works fine, but if I use that on the said ItemAdded event, the items don't load correctly and they don't show up. ( i see brief artifacts on the screen ). If I use for example a RadFadeAnimation the ItemAdded event works as intended, but that's not the animation I'm looking for.

I do want to point out that in the Defining Orientation section of the Windows 8 XAML documentation, it still references ItemHeight and ItemWidth as controlling the layout.

Hello Thomas,

Thank you for the valuable feedback. We will remove these properties from the documentation on the next update.
