RadDiagram by-step routing

Hi!

I would like to implement step by step routing not shape to shape like that:

- click on shape's connector

- click some points on diagram

- finally click another shape's connector

Clicks are marked as red circle in attechement 0.png. Is it possible and where should I start?

Another short question is about moving connection. Is there a way to avoid displacement of rigth angle between shape's connector and the first connection point? See illustration in attachement 1.png.

IsSynchronizedWithCurrentItem not working as expected

Using v2018-03:

According to https://docs.telerik.com/devtools/wpf/controls/radgridview/troubleshooting/first-row-always-selected I have to set IsSynchronizedWithCurrentItem =False when I don't want the first element to be selected automatically. Doing this the variable the SelectedItem is bound to is not overwritten, this is good. But the element referenced by SelectedItem is not highlighted in the tree. I need the tree to highlight the item referenced in SelectedItem as it was before the TreeListView instantiated.

Thanks in advance!

CellStyleSelector and PivotGrid

Is there a way to attach to the underlying CellStyleSelector event of the pivot's data grid?

Would like colorize the cell's background color depending on which group and row is selected.

I was trying to use the DataTemplateSelector selector before, but the UI virtualization was causing this to break when scrolled.

Text creating does not work while starting to draw text region at image or another shape

Hello!

Text creating does not work while starting to draw text region at image or another shape.

But when I start to draw text region at empty space it works and after that I can start drawing it at image too.

Could you tell me how to fix it? ( to make it work at first time?)

Best regards,

RadDropDownButton Control Template

Hi.

I'm trying to customize the RadDropDownButton and in order to do so i have to rewrite some triggers but in order to do so I must rewrite the complete control template!!!!

I've followed the tutorials to extract the template using Blend or Visual Studio but it seems somehow incomplete:

<Style x:Key="FocusVisual">

<Setter Property="Control.Template">

<Setter.Value>

<ControlTemplate>

<Rectangle Margin="2" SnapsToDevicePixels="true" Stroke="{DynamicResource {x:Static SystemColors.ControlTextBrushKey}}" StrokeThickness="1" StrokeDashArray="1 2"/>

</ControlTemplate>

</Setter.Value>

</Setter>

</Style>

<SolidColorBrush x:Key="Button.Static.Background" Color="#FFDDDDDD"/>

<SolidColorBrush x:Key="Button.Static.Border" Color="#FF707070"/>

<SolidColorBrush x:Key="Button.MouseOver.Background" Color="#FFBEE6FD"/>

<SolidColorBrush x:Key="Button.MouseOver.Border" Color="#FF3C7FB1"/>

<SolidColorBrush x:Key="Button.Pressed.Background" Color="#FFC4E5F6"/>

<SolidColorBrush x:Key="Button.Pressed.Border" Color="#FF2C628B"/>

<SolidColorBrush x:Key="Button.Disabled.Background" Color="#FFF4F4F4"/>

<SolidColorBrush x:Key="Button.Disabled.Border" Color="#FFADB2B5"/>

<SolidColorBrush x:Key="Button.Disabled.Foreground" Color="#FF838383"/>

<Style x:Key="RadDropDownButtonStyle1" TargetType="{x:Type Button}">

<Setter Property="FocusVisualStyle" Value="{StaticResource FocusVisual}"/>

<Setter Property="Background" Value="{StaticResource Button.Static.Background}"/>

<Setter Property="BorderBrush" Value="{StaticResource Button.Static.Border}"/>

<Setter Property="Foreground" Value="{DynamicResource {x:Static SystemColors.ControlTextBrushKey}}"/>

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

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

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

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

<Setter Property="Template">

<Setter.Value>

<ControlTemplate TargetType="{x:Type Button}">

<Border x:Name="border" BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}" Background="{TemplateBinding Background}" SnapsToDevicePixels="true">

<ContentPresenter x:Name="contentPresenter" Focusable="False" HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}" Margin="{TemplateBinding Padding}" RecognizesAccessKey="True" SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}" VerticalAlignment="{TemplateBinding VerticalContentAlignment}"/>

</Border>

<ControlTemplate.Triggers>

<Trigger Property="IsDefaulted" Value="true">

<Setter Property="BorderBrush" TargetName="border" Value="{DynamicResource {x:Static SystemColors.HighlightBrushKey}}"/>

</Trigger>

<Trigger Property="IsMouseOver" Value="true">

<Setter Property="Background" TargetName="border" Value="{StaticResource Button.MouseOver.Background}"/>

<Setter Property="BorderBrush" TargetName="border" Value="{StaticResource Button.MouseOver.Border}"/>

</Trigger>

<Trigger Property="IsPressed" Value="true">

<Setter Property="Background" TargetName="border" Value="{StaticResource Button.Pressed.Background}"/>

<Setter Property="BorderBrush" TargetName="border" Value="{StaticResource Button.Pressed.Border}"/>

</Trigger>

<Trigger Property="IsEnabled" Value="false">

<Setter Property="Background" TargetName="border" Value="{StaticResource Button.Disabled.Background}"/>

<Setter Property="BorderBrush" TargetName="border" Value="{StaticResource Button.Disabled.Border}"/>

<Setter Property="TextElement.Foreground" TargetName="contentPresenter" Value="{StaticResource Button.Disabled.Foreground}"/>

</Trigger>

</ControlTemplate.Triggers>

</ControlTemplate>

</Setter.Value>

</Setter>

</Style>

How can i get a complete copy of the RadDropDownButton styles and templates?

IsEnabled not working for ComboBox in PropertyGrid

The example below has a RadComboBox inside a RadPropertyGrid, with a Checkbox controlling the IsEnabled property of the RadComboBox. However, setting IsEnabled=false doesn't do anything. The same example works fine if I use a regular Grid instead of a RadPropertyGrid though.
