We have KeyTipService enabled on our RadRibbonView. Some of our users want to use Alt + Key Code (example Alt + 132) to insert special characters when typing into a textbox. The problem is RadRibbonView is trapping the Alt command when used this way.

Compare to an application like MS Word 2013. Just hitting Alt and releasing brings up the key hints for navigating the ribbon. Hitting Alt + 132 enters an "ä". With RadRibbonView, hitting Alt even if combined with other keys always brings up the hint text and prevents default behavior of the textbox.

Is there a way to prevent this?

Video Sync with Time Line Events on Click

New to using WPF and Telerik, but I have been tasked with trying to find a way to sync Telerik with a video playback.

Our customer has a video of a training sessions and he wants to put that into this program we have for After Action Reviews or AAR.

In this AAR program we have a Telerik Time line that shows at which point in the training certain events took place, and then the specific metrics of that event. Now they want to implement this video into the program so every time they goto the AAR there is a video of the training next to the Telerik Timeline.

What I need to figure out:

* How can I sync up the video and the Telerik timeline, so that if they click to look at a certain event, the Video jumps to the corresponding spot in the video. Or if they move the video slider to say 3min mark, the Telerik timeline ALSO moves to that exact spot.

Thanks

Prevent nodes from being selected

I have a RadTreeView bound in an MVVM style application. If a selection does not contain Details I need to disable the ability to click on that node and keep the currently selected node highlighted. The user should still able to expand and collapse.



I have tried to bind to PreviewSelected but the SelectedItem property still gets hit even if I switch e.handled = true and I lose the node highlighting on the currently selected node. 



<

UserControl.Resources>

<ResourceDictionary>

<Style x:Key="PHToCItemContainerStyle" TargetType="{x:Type telerik:RadTreeViewItem}" BasedOn="{StaticResource RadTreeViewDefaultItemPlusMinusStyle}">

<Setter Property="IsExpanded" Value="{Binding IsExpanded, Mode=TwoWay}"/>

<Setter Property="IsSelected" Value="{Binding IsSelected, Mode=TwoWay}"/>

</Style>

<DataTemplate x:Key="Measure">

<TextBlock Text="{Binding Name }" Style="{StaticResource RadTreeViewItemSelectedTextBlockDefaultStyle}" VerticalAlignment="Center"/>

</DataTemplate>

<HierarchicalDataTemplate x:Key="Condition" ItemTemplate="{StaticResource Measure}" ItemsSource="{Binding Measures}">

<TextBlock Text="{Binding Name}" Style="{StaticResource RadTreeViewItemSelectedTextBlockDefaultStyle}" />

</HierarchicalDataTemplate>

<HierarchicalDataTemplate x:Key="ConditionGroup" ItemTemplate="{StaticResource Condition}" ItemsSource="{Binding Conditions}" >

<TextBlock Text="{Binding Name }" FontWeight="Bold" Style="{StaticResource RadTreeViewItemSelectedTextBlockDefaultStyle}" />

</HierarchicalDataTemplate>

</ResourceDictionary>

</UserControl.Resources>

<telerik:RadTreeView

x:Name="RadTree"

telerik:TextSearch.TextPath="Name"

Loading Layout Loses DataBinding

When I load my layout all of my binding content is gone. I had a similar issue with Header content on a RadDocumentPane and the solution was to use a HeaderTemplate. This did resolve my issue with the header but when I try a similar approach with a ContentTemplate I have no success.

Is there a way to preserve my RadPane content when I load the layout?

I have the following XAML:

<telerik:RadPane x:Name="rpIndexPane" CanUserClose="False" ContextMenuTemplate="{x:Null}" CanDockInDocumentHost="False" Header="Index"

telerik:RadDocking.SerializationTag="IndexPane" DataContext="{Binding}">

<ItemsControl.Template>

</ScrollViewer>

</ControlTemplate>

</ItemsControl.Template>

<ItemsControl.ItemTemplate>

</Button>

</DataTemplate>

</ItemsControl.ItemTemplate>

</ItemsControl>

</telerik:RadPane>

Show diagram is slow

Hello,

I have a RadDiagram in which I load 400 items with almost 50 binding properties per-item, like for example BackgroundColor, FontSize, Width, Height, Visibility, etc…

Example of BackgroundColor property for binding:

private Brush backgroundColor ;
public Brush BackgroundColor
{
get{ return backgroundColor; }
set
{
backgroundColor = value;
OnPropertyChanged(“BackgroundColor”);
}
}

Each item is a derived class from MyNode:NodeViewModelBase with DataTemplate:

<telerik:RadDiagram.ShapeStyle>
<Style TargetType="telerik:RadDiagramShape">
<Setter Property="Position" Value="{Binding Position, Mode=TwoWay}" />
<Setter Property="Background" Value="{Binding BackgroundColor} " />
<Setter Property="BorderBrush" Value="Transparent" />
……………

The performance is very bad. It last up to 5 seconds to display the whole diagram with all items over it.

Any help to enhance the performance?

Loading layout breaks template bindings

Hello. I kind of necroposted in other thread about this issue. That thread seems to be inactive though, so I thought I might as well start a new one, and add some context.

So, long story short, I am trying to implement MVVM with RadDocking and I am having troubles with data binding. Whenever I call LoadLayout method all the binidings that were set in templates break, and i don't know how to fix them.

This is the global style, I'm applying to RadPanes:

<DataTemplate x:Key="HeaderTemplate">

<StackPanel Orientation="Horizontal">

<Image Margin="0,0,3,0" Source="{Binding Screen.IconSource}" Width="16" Height="16""/>

<TextBlock Text="{Binding Screen.Title}"/>

</StackPanel>

</DataTemplate>

<Style TargetType="{x:Type Controls:RadPane}">

<Setter Property="HeaderTemplate" Value="{StaticResource HeaderTemplate}"/>

<Setter Property="TitleTemplate" Value="{StaticResource HeaderTemplate}"/>

</Style>

This is my viewmodel class which represents a single pane:

public class ScreenViewModel

{

public ScreenViewModel(IScreen screen)

{

Screen = screen;

}

public IScreen Screen { get; private set; }

private

RadPane _pane;

          //this property is set in DockingPanesFactory.CreatePaneForItem method

public RadPane Pane

{

get { return _pane; }

set

{

_pane = value;

_pane.Content = Screen.View;

_pane.Header = this;

RadDocking.SetSerializationTag(_pane, Screen.ContentId);

}

//+some other irrelevant properties

}

//this is my model

interface IScreen

{

UIElement View { get; }

string Title { get; }

string ContentId { get; }

ImageSource IconSource { get; }

}

And this is how I load the layout:

public ObservableCollection<ScreenViewModel> Screens { get; set; }

public void Load(string file, IScreenFactory screenFactory)

{

if (!File.Exists(file)) return;

Screens.Clear();

using (var fs = File.OpenRead(file))

{

var doc = XDocument.Load(fs);

foreach (var screenId in doc.Descendants("RadPane").Select(x => x.Attribute("SerializationTag").Value))

{

//some factory wich creates models by their IDs

IScreen screen = screenFactory.RestoreScreen(screenId);

Screens.Add(new ScreenViewModel(screen));

}

if (Screens.Any())

{

fs.Position = 0;

//after this call all template the bindings break

_radDocking.LoadLayout(fs);

}

After the LoadLayout call I can see that header content is set, and that the template is applied, but the bindings set by this template are broken (VS Output is flooded by binding exceptions), which results in empty pane headers. What am I doing wrong?
