Hi. I was trying to run example code about 'AnnotationsProvider' feature from here:

https://github.com/telerik/xaml-sdk/tree/master/ChartView/WPF/AnnotationsProvider

However, it seems to me that it doesn't working as was supposed. Neither 'AnnotationDescriptor' or 'AnnotationDescriptorSelector' user control are not working properly (I had not seen any annotations at all). Only 'AnnotationCreated' user control drew the annotations by using code-behind event handler. What am i doing wrong?

My current Telerik libraries version is 2017.2.503.4

I want to add legends to doughnut char. Now the colors are hard coded in xaml. But I want to use MVVM. Not sure how to bind it?

1 I had a WPF project work with Kinect hand pointer and want do use Telerik RadCarouselPanel that bind with ListBox. the problem is that the hand pointer scroll speed is too fast, I tried ScrollViewer.CanContentScroll="False" but it break Telerik perspective effect on Listbox. how can I slow it down some how? here is the picture and the code:

 

    <ScrollViewer HorizontalAlignment="Center" Background="Transparent" VerticalAlignment="Center"  VerticalScrollBarVisibility="Disabled" HorizontalScrollBarVisibility="Disabled" Width="1691.381" Height="257.5" Grid.ColumnSpan="4"  Grid.RowSpan="3" Grid.Row="2">
<ListBox x:Name="listBox" Background="Transparent" BorderBrush="Transparent" SelectionChanged="listBox_SelectionChanged" SelectionMode="Single" ItemsSource="{Binding Source={StaticResource NamesTable}}" HorizontalContentAlignment="Center" ScrollViewer.HorizontalScrollBarVisibility="Auto" ScrollViewer.VerticalScrollBarVisibility="Disabled" RenderTransformOrigin="0.5,0.5"  >
<ListBox.ItemsPanel>
<ItemsPanelTemplate>
<telerik:RadCarouselPanel Name="MyCarousel" HorizontalAlignment="Center" VerticalAlignment="Center" Height="300"  Width="2000"/>
<!--<StackPanel Orientation="Horizontal" />-->
</ItemsPanelTemplate>
</ListBox.ItemsPanel>
<ListBox.ItemTemplate>
<DataTemplate>
<StackPanel Orientation="Horizontal"  Height="200" Width="200" >
<Image Margin="3" Source="{Binding pic_path}" RenderOptions.BitmapScalingMode="Fant" RenderOptions.EdgeMode="Aliased"/>
<TextBox Margin="3" Text="{Binding name}" Visibility="Visible"/>

</StackPanel>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
</ScrollViewer>

I am working on a gridview and need to change the appearance between the view mode and the edit mode. I tried to create implicit styles with data triggers to change the background color and font color in Header Row, but it did work.  I can't apply data triggers to head row?

 

Thanks.

 

Hi 

I am trying to copy diagram and then paste diagram.

Serialization and Deserialization is good work for copy, paste, create.

 

However, when i try to copy diagram to other view model, Link does not work.

I found this cause that diagram id was changed when copy diagram.

Except for that, All of that are good working.

 

I wonder some solutions to solve this problem. 

Thanks.

Hello.

We are currently testing the RadRichTextBox control and due to our specific business needs we cannot use the ribbon UI so we are applying styles programmatically.

We are using the sample code from the documentation which describes how to apply a linked style however it does not work in our case - only the paragraph style is applied but the character one is ignored.

Our environment is VS 2017.

.NET Framework 4.6.2. (tried with 4.5 but got the same result).

Here is the code:

StyleDefinition linkedParagraphStyle = new StyleDefinition();
                linkedParagraphStyle.Type = StyleType.Paragraph;
                linkedParagraphStyle.ParagraphProperties.Background = Colors.Yellow;
                linkedParagraphStyle.DisplayName = "linkedParagraphStyle";
                linkedParagraphStyle.Name = "linkedParagraphStyle";

                StyleDefinition linkedCharStyle = new StyleDefinition();
                linkedCharStyle.Type = StyleType.Character;
                linkedCharStyle.SpanProperties.FontWeight = FontWeights.Bold;
                linkedCharStyle.SpanProperties.FontFamily = new FontFamily("Times New Roman");
                linkedCharStyle.DisplayName = "linkedCharStyle";
                linkedCharStyle.Name = "linkedCharStyle";
                linkedParagraphStyle.LinkedStyle = linkedCharStyle;

                this.textBox.Document.StyleRepository.Add(linkedParagraphStyle);
                this.textBox.Document.StyleRepository.Add(linkedCharStyle);
                this.textBox.ChangeStyleName("linkedCharStyle");

 

No matter how we change the linking and the naming of the styles and linked properties it will not apply the character properties.

Any help would be greatly appreciated.

Regards,

R.F.

Hello,

 

I want to modify the icon that will be showed when a row in RadGridView is not valid. I found topics in yours forum, but just for WinForms, and the used event is not exists in WPF.

For WinForms, the ViewCellFormatting event is used, but I don't find the equivalent event for WPF.

 

Can you help me ?

 

Thank you.

How do I hide the current row highlight of a grid?

I have several GridViews on my interface and then on one it has a ChildTableDefinition.  I am trying to have the TAB key insert a row if pressed on the end of the last line on each GridView.  I have followed the instructions and created the KeyboardCommandProvider that overrides the ProvideCommandsForKey method. I have then wired up the KeyboardCommandProvider in the code behind

myGrid1.KeyboardCommandProvider = new Commands.TabKeyCommandProvider(myGrid1);

however the definition for my Child Table is done via a DataTemplate

<telerik:RadGridView.ChildTableDefinitions>
    <telerik:GridViewTableDefinition />
 </telerik:RadGridView.ChildTableDefinitions>
 <telerik:RadGridView.HierarchyChildTemplate>
    <DataTemplate>
           <telerik:RadGridView ItemsSource="{Binding custom_identifier}"
                                              x:Name="ChildGrid1"
                                              ShowGroupPanel="False"
                                              AutoGenerateColumns="False">
                          <telerik:RadGridView.Columns>
                                <telerik:GridViewDataColumn DataMemberBinding="{Binding label}"
                                                                            Header="Custom Identifier"
                                                                            IsSortable="True"
                                                                            IsFilterable="False" />
                           </telerik:RadGridView.Columns>
                </telerik:RadGridView>
          </DataTemplate>
 </telerik:RadGridView.HierarchyChildTemplate>

Now as this child Grid is defined in a template, I can not reference it using the x:Name of "ChildGrid1" in the code behind.  So how do I attach the custom Command Provider to this grid?

 

Also - is there an MVVM way of doing this as doing it in Code Behind is not ideal ??

 

Any suggestions welcome

I have a chart that has two plots on it. I also have a ribbon bar with a few buttons that I'd like to use to control the pan and zoom behaviors of the chart. I'd like to accomplish this exclusively in the XAML file using data triggers. Please excuse the long code snip, but I'd like to provide a complete picture.
