RichTextBox: When selecting spans, some of which belong to a list, the numbering option does not allow for adding them in the existing list

Performing selection on spans, some of which are present in a list, does not allow for including all of them in the list. Instead, the current list will have to be removed and reapplied to all selected spans.

MultiColumnComboBox: Search higlighting stops working when the ItemsSource is assigned while the drop down is open

The cell highlighting doesn't work if the ItemsSourceProvider.ItemsSource is set at runtime, while the drop down is open. The filtering of the items works, but the cell content is not colored.

To work this around, make sure to set the ItemsSource before the drop down gets opened.

PivotGrid - Data desappears when sorted

In your demo select PivotGrid - Olap Support

1. add "Exchange Rates: Average Rate" to values
2. sort rows by "Reseller Order Quantity"
-> The grid will be empty

If the list is filtered by "Total Reseller Order Quantity != 0", results will show again. Thus, sorting by a column which contains rows without values seems to be faulty.

Expander: NullReferenceException in the Visual Studio design-time when the IsExpanded property is data bound

The RadExpander element gets underlined in the Visual Studio designer and you can see a NullReferenceException when mouse over the element. The issue occurs only when data bind the IsExpanded property of RadExpander.

There are no issues at runtime. Also, in the common scenario the designer doesn't break. In case the error breaks the designer, you can set the IsExpanded bindining in the code-behind, instead of XAML.

public MainWindow()
{
    InitializeComponent();
    this.radExpander.SetBinding(RadExpander.IsExpandedProperty, new Binding("IsExpanded"));
}

Docking: Compass activation reacts on wrong position when using dragdrop between two RadDocking instances in different windows in per monitor dpi awareness scenario

Created by: Frank

Category: Docking

Type: Bug Report

Docking: Compass activation reacts on wrong position when using dragdrop between two RadDocking instances in different windows in per monitor dpi awareness scenario

In OS two monitors are configured: monitor 1 (3840x2160) scale: 200% and monitor 2 (1920x1200) scale 100%.

Our wpf application has a main window, maximized on screen 1 and a child window maximized on screen 2.

In the app.manifest we use per monitor dpi awareness:

<application xmlns="urn:schemas-microsoft-com:asm.v3">
  <windowsSettings>
    <dpiAware xmlns="http://schemas.microsoft.com/SMI/2005/WindowsSettings">True/PM</dpiAware>
    <dpiAwareness xmlns="http://schemas.microsoft.com/SMI/2016/WindowsSettings">PerMonitorV2,PerMonitor</dpiAwareness>
  </windowsSettings>
</application>

Both windows have a RadDocking instance with a docked RadPane like:

<Grid>
  <telerikDocking:RadDocking Name="Docking"                              
                             HasDocumentHost="True" 
                             telerik:DragDropGroup.Name="VDDragDropGroup">
    <telerikDocking:RadDocking.DocumentHost>
      
            ...
          
    </telerikDocking:RadDocking.DocumentHost>
    <telerik:RadSplitContainer InitialPosition="DockedBottom">
      <telerik:RadPaneGroup>
        <telerik:RadPane Header="Test Panel" IsDockable="True">
          <Border Background="Green">
            <TextBlock Text="Test Panel" HorizontalAlignment="Center" VerticalAlignment="Center"/>
          </Border>
        </telerik:RadPane>
      </telerik:RadPaneGroup>     
    </telerik:RadSplitContainer>
  </telerikDocking:RadDocking>
</Grid>

If you drag and move the docked panel from screen 2 to screen 1 the compass at screen 1 is only shown if the mouse position is in the first quadrant of screen 1 . The compass is shown on the correct place but cannot be activated, so that no dropping is possible.

Without unsing per monitor dpi awareness everything works fine. Unfortunately we must use per monitor dpi awareness for our application.

This bug is also reproducable in V2023.3.1218.

RibbonView: RibbonWindow's maximize icon is updated between its states in the Office2019 theme

Created by: Stenly

Type: Bug Report

RibbonView: RibbonWindow's maximize icon is updated between its states in the Office2019 theme

Using the RadRibbonWindow with the Office2019 theme, the maximize icon is updated when the button is interacted with (it does not change between the maximized and normal states).

To work around this behavior, extract the default ControlTemplate of the RadRibbonWindow element and add an additional Setter with TargetName="maximizeButton" for its Content property, to the Trigger for the WindowState property when its value is set to Maximized. For the Value property of the added Setter, create a new RadGlyph element and set its Glyph property to GlyphWindowCollapse.

The following code snippet showcases this suggestion's implementation:

<Style TargetType="telerik:RadRibbonWindow" BasedOn="{StaticResource RadRibbonWindowStyle}">
    <Setter Property="Template">
        <Setter.Value>
            <ControlTemplate TargetType="telerik:RadRibbonWindow">
                <Border x:Name="outerBorder" Background="{TemplateBinding WindowBackground}" CornerRadius="{TemplateBinding CornerRadius}">

                        <Grid telerik:CornerRadiusHelper.ClipRadius="{Binding ElementName=outerBorder, Path=CornerRadius}" telerik:CornerRadiusHelper.ClipRadiusOffset="{TemplateBinding telerik:CornerRadiusHelper.ClipRadiusOffset}" Margin="{TemplateBinding BorderThickness}">

DateRangePicker: ArgumentOutOfRangeException is thrown when the Separator property is set to a string that contains alpha-numeric/numeric "not required" mask tokens and the clear button is pressed

An ArgumentOutOfRangeException is thrown when the Separator property is set to a string that contains alpha-numeric/numeric "not required" mask tokens, and the clear button is pressed. The control works with a custom RadMaskedTextInput control to parse different date and time patterns for the start and end dates, which replaces the mask tokens with a placeholder, resulting in the exception when updating the Value property of the RadMaskedTextInput when the value is cleared.

ComboBox: ArgumentOutOfRangeException on ItemsSource reset when AllowMultipleSelection is True

ArgumentOutOfRangeException occurs when the ItemsSource of RadComboBox gets reset. To recreate this the IsSelected property of RadComboBoxItem should be bound too and multiple selection should be allowed.

To work this around, you can disable the autiomation peers globally:

AutomationManager.AutomationMode = AutomationMode.Disabled;

Or you disable them only for the RadComboBox:

public class CustomComboBox : RadComboBox
{
    protected override AutomationPeer OnCreateAutomationPeer()
    {
        return null;
    }
}

The stacktrace:

GridView: ArgumentOutOfRangeException raised with pixelWidth < 0 in call to RenderTargetBitmap constructor when adding a group descriptor

The following exception is raised when adding a ColumnGroupDescriptor to the GroupDescriptors property of a RadGridView. This bug is data specific and I've only been able to duplicate it with a large data set but the issue seems like it could be addressed without the actual data, given that the code causing the issue is apparently passing a pixelWidth < 0.

System.ArgumentOutOfRangeException: 'The parameter value must be greater than zero.

PersistanceFramework: Missing types regarding GridViewColumns cause exceptions when saving

Missing types regarding GridViewColumns cause exceptions when saving:

Workaround

Add the types manually:

radGridView.ItemsSource = sampleData;
manager.AllowGridViewControls();

manager.AllowedTypes.Add(typeof(GridViewToggleRowDetailsColumn));
manager.AllowedTypes.Add(typeof(GridViewDataColumn));
manager.AllowedTypes.Add(typeof(DependencyObject));
manager.AllowedTypes.Add(typeof(Size));
manager.AllowedTypes.Add(typeof(SizeConverter));

var gridViewColumnType = typeof(Telerik.Windows.Controls.GridViewColumn);
var assembly = gridViewColumnType.Assembly;

// Get the internal type by its full name
var internalType = assembly.GetType("Telerik.Windows.Controls.GridViewColumnCollectionInternal", throwOnError: false);

// Use the type as needed (for example, add to AllowedTypes if required)
if (internalType != null)
{
    manager.AllowedTypes.Add(internalType);
}

Licensing: The missing or invalid license dialog and watermark are shown even when a valid license key is installed in an addin project

Licensing: The missing or invalid license dialog and watermark are shown even when a valid license key is installed in an addin project

The dialog and the watermark stating that no license is found are displayed, even when the license key is installed properly. This happens in addin projects, like Excel VSTO Add-in.

To workaround this use the TelerikLicensing.Register method to install your license script key.

public MyWpfUserControl()
{
    TelerikLicensing.Register("your-script-key");
    InitializeComponent();
}

GridView: The scrolling becomes very slow when setting the left and right frozen columns to 0 and resizing the columns so that their summary width is smaller than the data grid's width

The vertical scrolling seems to become very slow and even unresponsive, when the following conditions are met:

left and right frozen columns count is 0
the summary width of all columns is smaller than the width of the RadGridView element

To minimize the issue, you can set the GroupRenderMode property of RadGridView to Nested.

GridView: Exception when resizing column with width set to star and min-width set to 0

Exception when resizing column with width set to star and min-width set to 0.

Set the properties to the above and resize a column to 0 and then to the original width -> an exception occurs.

GridView: The control hangs when resized and frozen columns are enabled (Fluent theme)

Created by: Martin Ivanov

GridView: The control hangs when resized and frozen columns are enabled (Fluent theme)

The RadGridView control hangs when the frozen columns are enabled and the application is resized. The exact resizing depends on the screen resolution and the exact new size. This was originally recreated on a monitor with 1600x900 resolution 125% DPI and the application was maximized (resized from restored to full screen size). The issue occurs in the Fluent theme. Also, the FluentPalette.Palette.ScrollBarsMode static property should be set to Normal.

To work this around, you can overrider the MeasureOverride method of RadGridView and add the following code:

public class CustomGridView: RadGridView
{
    private static readonly PropertyInfo internalColumnsProp = typeof(GridViewDataControl).GetProperty("InternalColumns", BindingFlags.Instance | BindingFlags.NonPublic);
    private static MethodInfo invalidateColumnsMethod;

    protected override Size MeasureOverride(Size availableSize)
    {
        if (EnableRowVirtualization && !double.IsInfinity(availableSize.Height))
        {
            var internalColumns = internalColumnsProp.GetValue(this);
            if (invalidateColumnsMethod == null)
            {
                invalidateColumnsMethod = internalColumns.GetType().GetMethod("InvalidateColumnWidthsCalculation", BindingFlags.Instance | BindingFlags.NonPublic);                     
            }

            invalidateColumnsMethod.Invoke(internalColumns, null);
        }
        return base.MeasureOverride(availableSize);
    }
