WPF Browser as Carousel Item

Hello,

I am using the radcarousel panel and currently I am facing problems with wpf browser element. Namely my carousel contains several frame - elements which are containing a XAML - Page, something like this:

    
                    <ScrollViewer x:Name="carouselScrollViewer" CanContentScroll="True" VerticalScrollBarVisibility="Hidden" Margin="0"> 
        
                        <telerik:RadCarouselPanel x:Name="mainMenuCarousel"  
        
                         ItemsPerPage="3" PathPadding="0,0,0,100" d:LayoutOverrides="Width, Height" ScrollViewer.VerticalScrollBarVisibility="Hidden"> 
        
                            <Frame Width="600" Height="400" Content="Frame" Source="\View\MediaPlayerView.xaml" NavigationUIVisibility="Hidden" IsEnabled="False" ScrollViewer.VerticalScrollBarVisibility="Disabled"/> 
        
                            <Frame Width="600" Height="400" Content="Frame" Source="\View\WebBrowserView.xaml" NavigationUIVisibility="Hidden" ScrollViewer.VerticalScrollBarVisibility="Disabled"/> 
        
                            <Frame Width="600" Height="400" Content="Frame" Source="\View\MediaPlayerView.xaml" NavigationUIVisibility="Hidden" ScrollViewer.VerticalScrollBarVisibility="Disabled" Focusable="False" IsTabStop="False"/> 
        
                        </telerik:RadCarouselPanel> 
        
                    </ScrollViewer>

So my WebBrowserView has an wpf browser element. While scrolling radcarousel wpf browser element stays always top element although frame containing it isn't a selected item and overlaps items in foreground. Is it a common bug in wpf browser element or there is something wrong with radcarousel ?

Thank you.

Animation when hiding pane

Hi!

I am using the "IsHidden" property to hide RadPanes in my WPF application.
This works fine.

What I want to do is to animate the "hiding/showing" of the panes. Is this possible?

Computed Columns / Derived Columns

Can I have a column whose value is derived from the difference of a column in two rows. Like:

For example I have following radgrid:

Row_Id Rank Derived Col

1 5 0

2 7 2

3 7 0

4 3 -4

Derived col = TableRow.Rank - TableRow(-1).Rank

Is it possible using bindings?

Scroll button only visible after window resizing

Hi,

I came across this scenario that appears to be a bug. When I bind a series of items to a RadTabControl that is not wide enough to show them the scroll buttons do not appear until I resize the window. This is the simplest way to duplicate:

XAML:

<Window x:Class="Workbench.RadTabControlTest"

xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

xmlns:Controls="clr-namespace:Telerik.Windows.Controls;assembly=Telerik.Windows.Controls.Navigation" Title="RadTabControlTest" Height="400" Width="500">

<Grid>

<Grid.RowDefinitions>

</Grid.RowDefinitions>

<Button

Width="125"

Height="25"

Click="Button_Click">Set Items</Button>

<Controls:RadTabControl

x:Name="tabs"

Width="250"

Height="150"

Grid.Row="1"

/>

</Grid>

</Window>

And the code behind:

public partial class RadTabControlTest: Window

{

public RadTabControlTest()

{

InitializeComponent();

}

private void Button_Click(object sender, RoutedEventArgs e)

{

tabs.ItemsSource = new[] {"one", "two", "three", "four", "five", "six", "seven", "eight", "nine", "ten"};

}

I am using the latest release and the project is .NET 4.0.

Am I doing something wrong?

Cheers,

Jose

Explicitly Inserting LineBreaks in ColumnHeaders

How can I explicitly indicate that I want a linebreak to be at a certain point in GridViewDataColumn header attribute?

    
            <telerik:GridViewDataColumn Header="Happy<LineBreakHere>(Days)"/>

I want the text to be centered with (Days) appearing underneath "Happy", and I want to do this without implementing any Wrapping/ColumnWidth tricks.

_CreateDelegate not found

I get the following error when I try creating a custom class and wire up to an event in the CellTemplate of a RadGridView. Can anyone explain why this is? I know it is not my code because when I use the custom class in the host page directly, it works.

'MyHyperlink_OnClick' value cannot be assigned to property 'OnClick' of object 'WpfBrowserApplication3.MyHyperlink'. Method 'WpfBrowserApplication3.Page1._CreateDelegate' not found. Error at object 'WpfBrowserApplication3.MyHyperlink' in markup file 'WpfBrowserApplication3;component/page1.xaml' Line 14 Position 24.

I would attache a sample, but the site is not allowing me. Thanks.
