GridView: Empty cells when GroupRenderMode is Flat and the control is resized

Empty cells appear when the RadGridView contains many cells in the viewport and the view gets resized.

To work this around you can extract and modify the ControlTemplate of GridViewCell, in order to set the MinHeight property of the "PART_ContentPresenter" element to a number close to the RowHeight of the RadGridView control.

GridView: CellUnloaded is not invoked when the view is scrolled

The CellUnloaded event of RadGridView is not invoked consistent compared to CellLoaded. For example, when you scroll up and down, the CellLoaded event is invoked for each new cell that appears in the view port. However, CellUnloaded is not invoked for cells going outside of the viewport.

Window: InvalidOperationException is thrown when closing a window opened on another UI thread and the Windows11 theme is applied

Window: InvalidOperationException is thrown when closing a window opened on another UI thread and the Windows11 theme is applied

InvalidOperationException when closing a RadWindow opened on a separated UI thread. The exception message is: "Cannot use a DependencyObject that belongs to a different thread than its parent Freezable."

To work this around, you can merge the Telerik.Windows.Controls.Navigation.xaml dictionary in the Resources of all RadWindow instances open on another thread and then set their Style property to the RadWindowStyle from the merged .xaml dictionary.

Map: Custom map provider based on BingRestMapProvider does not display tiles

When you inherit BingRestMapProvider and BingRestTileMapSource, following the custom map provider approach
https://docs.telerik.com/devtools/wpf/controls/radmap/how-to/howto-custom-provider

the map does not display any tiles. This is due to internal property TopLayer not set correctly to the TileMapSource class.

In the StyleFormattingPropertiesDialog, the value of the property FontSize is displayed incorrectly

Created by: Caesar

Comments: 1

Category: RichTextBox

Type: Bug Report

In the StyleFormattingPropertiesDialog, the value of the property FontSize is displayed incorrectly

If FontSize is not explicitly set in the style, the value displayed in the StyleFormattingPropertiesDialog is 16, which is from the const DocumentDefaultSettings.DEFAULT_FONT_SIZE.

But when rendering document, the actural font size is from the StyleDefinition "defaultDocumentStyle".

So if the FontSize in the StyleDefinition "defaultDocumentStyle" is set to a value other than 16 (I set it to a value of 12 in the attached document), the FontSize displayed in the StyleFormattingPropertiesDialog is incorrect.

DateTimePicker: The names of the DependencyProperty and the CLR property of IsDropDownOpen don't match

The CLR property is named IsDropDownOpen, but the DependencyProperty has a type and it is named IsDownOpen. This works at runtime, but it brings an error at design-time.

The error says: "The property "IsDropDownOpen" is not a DependencyProperty. (some additional description here)"

Callout: Setting CanPopupExceedScreen of CalloutPopupSettings to true works only initially

Type: Bug Report

Callout: Setting CanPopupExceedScreen of CalloutPopupSettings to true works only initially

The CanPopupExceedScreen=true setting is not taken into account when the parent window is moved. In that case if the popup reaches the edge of the screen, it will reposition so it doesn't go outside of it. This is the default behavior and setting CanPopupExceedScreen=true should disable it.

To work this around, you can override the OnLocationChanged method of the hosting window and invoke the private ForcePopupPosition method of CalloutPopupService, using a reflection.

 protected override void OnLocationChanged(EventArgs e)
  {
      var popup = this.callout.ParentOfType<Popup>();
      if (popup != null && popup.IsOpen)
      {
          var methodInfo = typeof(CalloutPopupService).GetMethod("ForcePopupPosition", System.Reflection.BindingFlags.Static | System.Reflection.BindingFlags.NonPublic);
          methodInfo.Invoke(null, new object[1] { popup });
      }
  }

pdf viewer selection

Using the mouse to select text inside the `PdfViewer` does not correctly select the text, sometimes it even selects the text of the next line.
The visual indicator of the selected area is slightly above the text as you can see in the attached screenshot.

VirtualizingWrapPanel: Missing item containers when move action is executed over the items collection at runtime

Some items are not rendered when the collection changed of the Items collection of the panel occurs with Move action. Some situations where this can happen are calling the Move() method of observable collection or using the live sorting feature of ListCollectionView, which internally moves the items.

GridView: Column groups disappear when new instances are created and RadGridView is hosted in a TabControl

Column groups may disappear when the RadGridView control is hosted in a TabItem of TabControl. These column groups can disappear when new GridViewColumnGroup instances are created.

Furthermore, resizing a column of RadGridView will result in a NullReferenceException.

To work this around, set the EnableColumnGroupsVirtualization property of RadGridView to False.

RibbonView: Wrong size of the popup showing the minimized tab content after changing the size of the RibbonView in the Windows 11 theme

RibbonView: Wrong size of the popup showing the minimized tab content after changing the size of the RibbonView in the Windows 11 theme

The width of the popup element that shows the selected tab content when RadRibbonView is minimized is wrong in the following situation. A tab in the minimized ribbon is clicked to display its content, then the tab is clicked again. After that, the width of the ribbon is changed. At this point when you open the minimized content, the popup uses the previous size of the RadRibbonView control.

To work this around, you can manually update the MaxWidth of the popup content element on size changed.

public class CustomRibbonView : RadRibbonView
{
    private ContentPresenter popupContent;

    public override void OnApplyTemplate()
    {
        base.OnApplyTemplate();
        this.popupContent = this.GetTemplateChild("SelectedTabContentPopup") as ContentPresenter;
    }

    protected override void OnRenderSizeChanged(SizeChangedInfo sizeInfo)
    {
        base.OnRenderSizeChanged(sizeInfo);
        if (popupContent != null)
        {
            double popupContentPadding = 16;
            popupContent.MaxWidth = this.ActualWidth - popupContentPadding;
        }
    }
}
