WrapPanel as container of subitems of expanded node

Hi -
I am trying to implement treeview that will have multiple expandable 1st level nodes. When one of the 1st level nodes is expanded, subitems of that node (they should not be expandable) should be displayed as a grid. I tried with setting Wrap panel for ItemsPanel, but in that case virtualization stops working.

<Style TargetType="telerik:RadTreeViewItem" x:Key="RadTreeViewItemStyle">

<Setter Property="FocusVisualStyle" Value="{x:Null}"/>

<Setter Property="HorizontalContentAlignment" Value="Left"/>

<Setter Property="VerticalContentAlignment" Value="Center"/>

<Setter Property="BorderThickness" Value="1"/>

<Setter Property="Padding" Value="1 4 5 4"/>

<Setter Property="MinHeight" Value="24"/>

<Setter Property="IsDropAllowed" Value="True"/>

<Setter Property="IsEnabled" Value="True"/>

<Setter Property="IsTabStop" Value="False"/>

<Setter Property="KeyboardNavigation.TabNavigation" Value="Local"/>

<Setter Property="Template" Value="{StaticResource TreeViewItemDefaultTemplate}"/>

<Setter Property="ItemsPanel">

<Setter.Value>

<ItemsPanelTemplate>

<WrapPanel Orientation="Horizontal" VerticalAlignment="Bottom"/>

</ItemsPanelTemplate>

</Setter.Value>

</Setter>

</Style>

When I set telerik:TreeViewPanel for ItemPanel, virtualization is working, but subitems of nodes are shown in a vertical list?

Is there any way to achieve that behavior, so subitems are shown in wrap panel, but to keep virtualization working?

Thanks in advance!

Change each Bar color in RadCartesianChart

Hi,

I am creating a RadCartesianChart and adding bar series this way:

chartSafety.VerticalAxis = new LinearAxis();

chartSafety.HorizontalAxis = new CategoricalAxis();

DataTable dtSafety = new DataTable("DATA");

dtSafety.Columns.Add(new DataColumn("Name", typeof(string)));

dtSafety.Columns.Add(new DataColumn("ValueBar", typeof(double)));

dtSafety.Rows.Add(new object[] { "Value1", 70 });

dtSafety.Rows.Add(new object[] { "Value2", 15 });

dtSafety.Rows.Add(new object[] { "Value3", 34 });

dtSafety.Rows.Add(new object[] { "Value4", 87 });

dtSafety.Rows.Add(new object[] { "Value5", 45 });

dtSafety.Rows.Add(new object[] { "Value6", 22 });

dtSafety.Rows.Add(new object[] { "Value7", 33 });

dtSafety.Rows.Add(new object[] { "Value8", 65 });

dtSafety.Rows.Add(new object[] { "Value9", 19 });

dtSafety.Rows.Add(new object[] { "Value10", 41 });

BarSeries barSer = new BarSeries();

foreach (DataRow drSafety in dtSafety.Rows)

{

barSer.DataPoints.Add(new CategoricalDataPoint() { Category = drSafety["Name"], Label = string.Format("{0:N}", drSafety["ValueBar"]), Value = double.Parse(drSafety["ValueBar"].ToString()) });

}

chartSafety.Series.Clear();

chartSafety.Series.Add(barSer);

Is there a way to change the color for each bar in the series while I am creating each data point?

Regards,

Alberto

AnnotationsProvider's problem...

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

Linked style not working.

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.
