I think that this is a general question: I have a RadDocking with document host. Generally I can load many tab inside the panel, every tab has his viewmodel that it is an instance of the same class.
When I binding a control property to a viewmodel property I need to bind it to the correct instance.
Now I use binding in code behind using a variable index such as 

pane.SetBinding(RadPane.HeaderProperty, new Binding()
{
    Path = new($"MainVM.Partitions[{_vm.MainVM.PartitionAttiva.Partition.Id}])
});

Hello.  I'm trying to create a vertical RadSlider with a custom Thumb that will display the current value of the slider, and has a pair of up/down buttons that the user can click to increment the slider by a fixed amount.

I've styled my Thumb to have Height="30" and Width="100", and the custom thumb appears as expected.  However, there are two problems.  First, because my RadSlider has Orientation="Vertical", I'm only able to drag the slider until the thumb is 100 px below the top of the slider - the width of the Thumb.  When the Thumb is at the maximum position, the slider value is 100% - but I'd like the Thumb to move through the entire length of the slider's Track.

The second problem is, when the slider is set to zero, the custom content of my Thumb appears below the bottom of the slider - I would like it to be centered on the bottom of the slider's Track.

Setting a margin on the Thumb only changes the proportion of "dead" space in the slider; if the Margin is 50, then I can only drag to within 50 px of the top or bottom of the slider.

Thank you!

When I use the WindowsFormsHost in Radbusyindicator,

then I change the window size, and the UI shows very slowly and seems wrong.

The content of the WindowsFormsHost is just a Label.

I am not sure if there are some details in this case.

<telerik:RadBusyIndicator IsBusy="False">
        <Grid>
            <Grid.RowDefinitions>
                <RowDefinition Height="*"/>
                <RowDefinition Height="30"/>
            </Grid.RowDefinitions>
            <WindowsFormsHost>
                <cc:UserControl1/>
            </WindowsFormsHost>
        </Grid>
    </telerik:RadBusyIndicator>

Hello! I have a RadGanttView with custom columns (which can be switched on and off on fly). The problem is that after any interaction with this control GridView part shows horizontal scroll bar, but splitter doesn't go right although there is more than enough space to resize (Picture 1).

It doesn't really matter how many columns are there - GridView resizes itself to be a bit smaller than enough to fit all the columns and doesn't expand anymore (Picture 2), leaving at least 0.5 cm of free space on the right (on 17" FullHD display) (Picture 3).

At the same time there is no problem with shrinking, it's possible to move splitter to the left until GridVIew part becomes completely invisible.

Thanks, Dmitrii

UPD: I've checked variables in Dynamic Visual Tree and found that ExtentWidth of TreeRenderingPanel element is always 3 units more than needed. Is there a way to fix this?

not sure why the size of the combobox arrow is that small , any idea how to change it?

Thanks,

Hello,

I noticed that the RadRichTextBox is not working as expected.

According to the documentation, SHIFT + ENTER should create a new line and ENTER a new paragraph.
For some reason the ENTER key is not working. My final go is to switch between SHIFT + ENTER and ENTER as described in the following link:

https://www.telerik.com/forums/wpf-radrichtextbox---swapping-enter-key-and-shift-enter-keys-behavior

How can I do that? the AcceptReturn is set to True, but the PreviewKeyDown event is not triggered for ENTER.

Hi Team,

In my LineSeries chart I want to change the color of the line dots based on a property of my bound list item.

The ItemSource of my LineSeries is an ObservableCollection<MonthlyTracking> . The MonthlyTracking class looks like this:

   public class MonthlyTracking : INotifyPropertyChanged
    {
        [....]

        private string monthString;
        public string MonthString
        {
            get => this.monthString;
            set
            {
                this.monthString = value;
                this.OnPropertyChanged(nameof(this.MonthString));
            }
        }

        private double actualValue;
        public double ActualValue
        {
            get => this.actualValue;
            set
            {
                this.actualValue = value;
               this.OnPropertyChanged(nameof(this.ActualValue));
            }
        }

        private int statusId;
        public int StatusId
        {
            get => this.statusId;
            set
            {
                this.statusId = value;
                this.OnPropertyChanged(nameof(this.StatusId));
            }
        }

     [....]

    }

My XAML Code looks like this:

<telerik:RadCartesianChart>
     <telerik:RadCartesianChart.HorizontalAxis>
        <telerik:CategoricalAxis ShowLabels="True"/>
     </telerik:RadCartesianChart.HorizontalAxis>
	 
     <telerik:RadCartesianChart.VerticalAxis>
        <telerik:LinearAxis />
    </telerik:RadCartesianChart.VerticalAxis>
                
	<telerik:RadCartesianChart.Series>                   
         <telerik:LineSeries ItemsSource="{Binding MonthlyTrackingList}" CategoryBinding="MonthString" ValueBinding="ActualValue" >
             <telerik:LineSeries.DefaultVisualStyle>
                <Style TargetType="Path">
                    <Setter Property="Width" Value="10" />
                    <Setter Property="Height" Value="10" />     
                    <Style.Triggers>
                        <DataTrigger Binding="{Binding StatusId}" Value="1">
                            <Setter Property="Fill" Value="LimeGreen" />
                        </DataTrigger>
                        <DataTrigger Binding="{Binding StatusId}" Value="2">
                            <Setter Property="Fill" Value="LightCoral" />
                        </DataTrigger>
                    </Style.Triggers>
                </Style>
            </telerik:LineSeries.DefaultVisualStyle>
         </telerik:LineSeries>
    </telerik:RadCartesianChart.Series>
	
</telerik:RadCartesianChart>

The line is drawn in the chart. Unfortunately my binding in telerik:LineSeries.DefaultVisualStyle is wrong. The property StatusId is not found. Can you help me?

Kind regards,

Mario
