Hi,
In project we have noticed that sometimes for RadDiagram.ConnectionManipulationCompleted we receive unexpected values in event.
This problem is not systematic but it occurs often at the drag of new connection.
To make it reproducible for you I used CustomConnectors sample project from Diagram.
For easier analysis I recorded a video with bug and changes to CustomConnectors project.
Best regards,
Bartosz
I have a Pie chart like this:
<telerik:RadPieChart Palette="Arctic">
<telerik:DoughnutSeries ItemsSource="{Binding GraphedStatistics, Mode=OneTime}" ValueBinding="Previous" ShowLabels="True">
<telerik:DoughnutSeries.LabelDefinitions>
<telerik:ChartSeriesLabelDefinition>
<telerik:ChartSeriesLabelDefinition.Template>
<DataTemplate>
<StackPanel Opacity="{Binding Value, Mode=OneWay>
<TextBlock Text="{Binding DataItem.Name}" HorizontalAlignment="Center" Foreground="{StaticResource textBlockForeground}"/>
<TextBlock HorizontalAlignment="Center" Foreground="{StaticResource textBlockForeground}">
<Run Text="{Binding Value, Mode=OneWay, StringFormat=' {0:#}'}"/>
<Run Text="{Binding Percent, Mode=OneWay, StringFormat=' ({0:#}%)'}"/>
</TextBlock>
</StackPanel>
</DataTemplate>
</telerik:ChartSeriesLabelDefinition.Template>
</telerik:ChartSeriesLabelDefinition>
</telerik:DoughnutSeries.LabelDefinitions>
</telerik:DoughnutSeries>
If I generate a pie or doughnut chart the Percent is not updated when I update a value in the bound data source (GraphedStatistics). Note: I am updating the observable collection not replacing it. The graph is redrawn correctly and Value updates correctly.
The version is 22.1.1.0 (not in the options below)
Updated (See that 'Monaco' is the same percentage as before the update, Value is correct and the UI Graph is correct but the segment is clearly not 26%)
Hello,
When I do the following:
and I assign this style to my dynamically created columns from a behavior attached to the RadGridView, the style of the tooltip is the same as the style of the header.
They seem to share the same style, so that when I change one property on the header, the tooltip gets the same, and vice-versa.
Do you repro? I'm on version 2020.3.1020.45.
Thanks,
Arthur
I am using a RadTreeListView with MaterialDesign theme in a Windows WPF application. By default the selected cell is indicated by a grey line at the bottom of the cell. I don't want an indication for the selected cell and used the advise from forum to change the style as follows:
<Style TargetType="telerik:GridViewCell" BasedOn="{StaticResource GridViewCellStyle}">
<Setter Property="CurrentBorderBrush" Value="Transparent"/>
</Style>
This works fine.
But if changing the Windows application with Alt+Tab and then back to my application with Alt+Tab the cell selection (grey underline) is displayed.

Right now, it is not easy to disable styles for standard controls like Button.
Especially when using NoXaml.
You have to create an Empty style on Application level for the control to "rewind" its style.
I do believe this kind of style drags down performance of controls when unloading, since it causes StyleChanged events.
Some explanation about performance (how things work to my understanding). Might be BS, but I spend a few hours debugging through .net code to get this idea:
Issue is, that when control is unloaded, its not part of the logical / visual tree of the application anymore, so it falls back to styles defined on assembly level.
e.g. Themes/Generic.xaml. So the empty styles defined on Application level do not count anymore, but the ones you defined in your theme.
This can be observed on RadTabbedWindow. When unloading pages (like switching between them), controls fall back to the styles defined in the theme from Telerik.Windows.Controls.Navigation, because they are still children of that page.
You can observe this behaviour if you set a Breakpoint in FrameworkElement.OnStyleChanged before unloading a control tree.
If you'd remove the System.Windows.xaml from your theme-dictionaries so that one can decide to merge those styles or not, that would be great.
I've just updated Telerik and are now getting this compile time error:
Severity Code Description Project File Line Suppression State
Error XDG0047 The specified value cannot be assigned. The following type was expected: "IFilteringControl". Modelkatalog.Client C:\develop\data-tool-modelkatalog\Modelkatalog.Client\Controls\List\CarVariantsList.xaml 1
I'm getting this error from 2 XAML documents that both implement a custom Fitler for the RadGridView
I didn't get this error before, and I'm still able to compile and run the project - which kind of defeat the purpose of [Severity: Error]
When selecting a Cell using the Mouse, the BorderColor is different to when navigating via ArrowKeys.
Also it seems that the Property IsSynchronizedWithCurrentItem does not work correctly when using ArrowKeys.
The issue with the Color can be observed in the Demo
Using the microsoft word,In docx document,inserting a shape,and add the text context to the shape,then save.
when radrichtextbox open the file,the program crashed.
private void NotifyIcon_TrayContextMenuOpening(object sender, CancelEventArgs e)
{
BuildContextMenu(NotifyIcon.TrayContextMenu);
if (!App.Current.MainWindow.IsLoaded)
NotifyIcon.TrayContextMenu.IsOpen = true;
}
