RadCoverFlow can't set invisible for the Image

[Huy Truong The]

Dear,

I met a problem when using  RadCoverFlow control.  That is I can't set invisible for the Image in the RadCoverFlow control.

Here is my sample :

xmlns:telerikNavigation="clr-namespace:Telerik.Windows.Controls;assembly=Telerik.Windows.Controls.Navigation"

 

   <Grid x:Name="LayoutRoot" Background="Ivory">

        <Grid.RowDefinitions>

            <RowDefinition Height="Auto"></RowDefinition>

        </Grid.RowDefinitions>

        <StackPanel Grid.Row="0">

            <telerikNavigation:RadCoverFlow x:Name="coverFlow" CameraY="-80" ItemMaxHeight="160"

            SelectedIndex="0" CenterOffsetY="50" SelectedItemMouseUp="coverFlow_SelectedItemMouseUp">             

                <Image x:Name="imgOrgan" />

                <Image x:Name="imgAcc"></Image>

                <Image x:Name="imgAuthen" ></Image>

            </telerikNavigation:RadCoverFlow>

        </StackPanel>

    </Grid>

 

In Code Behind, set invisible the Image control like that :

        public DashBoard()

        {

            InitializeComponent();

            //that function set image source for image control

SetImage();

            imgAcc.Visibility = Visibility.Collapsed;

            imgAuthen.Visibility = Visibility.Collapsed;

        }

Result:

All Image control is displayed(imgAcc and imgAuthen is not collapsed althought I set it to collapsed status by code behind).

 

Expected result are :

- The image imgOrgan is displayed

- The Image imgAcc,imgAuthen is not displayed

Could you help me solve this problem? thank  you for your help

Best regards,

Huy

Hi Huy Truong The,

Yes, this is the expected behavior as the CoverFlow control doesn't actually show the Image controls, but a CoverFlowPerspectiveItem control. Unfortunately the CoverFlowPerspectiveItem cannot be collapsed as it uses its Visibility property internally. I could suggest you to remove the Image from the Items collection if you are not using ItemsSource. If you do, you could remove it from the source collection. We will track the issue, but I cannot give you any timeframe for that.
