With the following code I'm not getting the pdfviewer working:

<telerik:RadPdfViewer Name="PdfViewer" />

byte[] readAllBytes = File.ReadAllBytes(@"C:/Temp/Invoicer.Data/Rechnungsscans/K4967.pdf");
var memoryStream = new MemoryStream(readAllBytes);
this.PdfViewer.DocumentSource = new PdfDocumentSource(memoryStream, FormatProviderSettings.ReadAllAtOnce);

I'm using the version 2013.2.724.40. Passing the filename hard-coded in the xaml code also not works! Can someone give an hint??

Inheriting styles when pasting

Hello,

Is there a way to inherit the current font settings when pasting text into a RadRichTextBox that was copied from another RadRichTextBox?

If the destination has the text "original text" with Arial font and the source has the text "testing" with no font specified, copying and pasting after "original" should show "original testing text" with Arial font.

The following is what I'm trying:

XAML:

<t:RadRichTextBox Name="txt" Grid.Row="1" FontFamily="inherited" DocumentInheritsDefaultStyleSettings="True"

/>

<TextBox Name="html" Grid.Row="2" HorizontalScrollBarVisibility="Auto" VerticalScrollBarVisibility="Auto"/>

Code Behind:

01.public MainWindow()

02.{

03. InitializeComponent();

04.

05. txt.ChangeParagraphSpacingAfter(0);

06. txt.DocumentContentChanged += TxtOnDocumentContentChanged;

07.}

08.

09.private void TxtOnDocumentContentChanged(object sender, EventArgs eventArgs)

10.{

11. UpdateHtml();

12.}

13.

14.private void UpdateHtml()

15.{

16. var settings = new HtmlExportSettings();

17. settings.DocumentExportLevel = DocumentExportLevel.Fragment;

18. settings.ExportStyleMetadata = false;

19. settings.StylesExportMode = StylesExportMode.Inline;

20.

21. var converter = new HtmlFormatProvider();

22. converter.ExportSettings = settings;

23. html.Text = converter.Export(txt.Document);

24.}

The output shows the following:

<p class="Normal "><span style="font-family: 'Arial';">Original </span>testing<span style="font-family: 'Arial';"> text</span></p>

This causes testing to still be "inherited" since it is not inserted as a child of the span with "Original". Is there any way I can do this or do I need to take over the Paste logic?

Thanks,
Wil

GridViewToggleButton not showing in the second level Hierarchical Grid

Telerik,

I have a problem trying to show the GridViewToggleButton in the second level of the Hierarchical Grid, the problem could have been solved if HasHierarchy had a setter. Since this is not achievable through code and because I was able to use WPF Inspector to change the value of HasHierarchy to make the GridViewToggleButton visible, I would like to request you to find me a workaround to solve this issue.

01.<telerikGrid:GridViewToggleButton MinHeight="24" MinWidth="24" IsHitTestVisible="{Binding IsExpandable, RelativeSource={RelativeSource TemplatedParent}}" Grid.Column="2" IsChecked="{Binding IsExpanded, Mode=TwoWay, RelativeSource={RelativeSource TemplatedParent}}" telerikGridView:SelectiveScrollingGrid.SelectiveScrollingOrientation="Vertical">

02. <telerikGrid:GridViewToggleButton.Opacity>

03. <Binding Path="IsExpandable" RelativeSource="{RelativeSource TemplatedParent}">

04. <Binding.Converter>

05. <telerik:BooleanToOpacityConverter/>

06. </Binding.Converter>

07. </Binding>

08. </telerikGrid:GridViewToggleButton.Opacity>

09. <telerikGrid:GridViewToggleButton.Visibility>

10. <Binding Path="HasHierarchy" RelativeSource="{RelativeSource TemplatedParent}">

11. <Binding.Converter>

12. <telerik:BooleanToVisibilityConverter/>

13. </Binding.Converter>

14. </Binding>

15. </telerikGrid:GridViewToggleButton.Visibility>

16.</telerikGrid:GridViewToggleButton>

17.<Border Grid.Column="2" BorderBrush="#FFB3B3B3" BorderThickness="0,0,1,0" telerikGridView:SelectiveScrollingGrid.SelectiveScrollingOrientation="Vertical">

18. <Border.Visibility>

19. <Binding Path="HasHierarchy" RelativeSource="{RelativeSource TemplatedParent}">

20. <Binding.Converter>

21. <telerik:BooleanToVisibilityConverter/>

22. </Binding.Converter>

23. </Binding>

24. </Border.Visibility>

25.</Border>

Regards,
Jerric Lyns John

P.S. The first level Hierarchical Grid works just fine by showing the GridViewToggleButton but when it comes to the second level, it seems somehow internally HasHierarchy is set as False

How to set RadPropertyGrid DataContext

Hello,

I've got a domain model info class, basically some get-only properties on an INotifyPropertyChanged class. I set the DataContext to an instance of this, but nothing is happening for the RadPropertyGrid. No properties show up.

Question: do the properties need to be settable? Or otherwise have ReadOnlyAttribute attached to them?

Thank ye...

Best regards.

[Solved] problem when bind image and header name

Hi,

I had a separate radpane xaml class, it would dynamically generated radpane if it needs.

My problem is when I bound HeaderName to Header without HeaderTemplate code(where I commented), it is working fine to show headername only. But if I uncommented HeaderTemplate code, I only got image show in the UI, no text.
Below is my code:

<telerik:RadPane x:Class="TemplatorWPF.LoadSource" x:Name="RadPaneSource"

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

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

xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"

xmlns:d="http://schemas.microsoft.com/expression/blend/2008"

xmlns:telerik="http://schemas.telerik.com/2008/xaml/presentation"

xmlns:local="clr-namespace:_ViewModel;assembly=_ViewModel"

mc:Ignorable="d" Header="{Binding HeaderName}"

d:DesignHeight="300" d:DesignWidth="300">

<!--<telerik:RadPane.HeaderTemplate>

<DataTemplate>

<StackPanel Orientation="Horizontal">

<Image Source="../Resources/templator - level 1.png" />

<TextBlock Text="{Binding HeaderName}"/>

</StackPanel>

</DataTemplate>

</telerik:RadPane.HeaderTemplate>-->

<telerik:RadPane.Resources>

Dynamically add View Model RadPane to DocumentHost

Hello,

I've got one or more File View Models, I open them through the command pattern and they land in a "Workspace" view model. It has a Files properties that is an observable collection. There is also the concept of Workspace opened documents and/or ActiveDocument, which should cause the corresponding pane to land in a default DocumentHost and/or activate.

Anyhow, as far as I can figure, I need to be inheriting from RadPane in order to cook up any document or tool windows. Which themselves either aggregate our custom UserControl or themselves have the XAML specified.

Is there a tutorial I can study along these lines?

Thank you.

Best regards.

KeyDown event not triggering on arrow up and down

If I type a letter it goes to the event, but not the arrow keys.

KeyUp does catch the arrow keys, so that's what I'm going to use

I'm basically doing this to put things in edit mode on the arrow up and arrow down:

private void handleArrows(object sender, KeyEventArgs e)

{

RadGridView rgv = (RadGridView)sender;

if (e.Key == Key.Down)

{

RadGridViewCommands.MoveDown.Execute(null);

rgv.BeginEdit();

e.Handled = true;

}

if (e.Key == Key.Up)

{

RadGridViewCommands.MoveUp.Execute(null);
