To reproduce:

-double click an option in the MultiColumnCombobox editor and close the editor in the selected index changed event.

Other themes are also missing the IsSelected state, the fix should also handle them.

Caret jumps several symbols to the right when arabic or persian is used and user deletes the dot symbol. As a result the wrong symbol is deleted.

One should not be able to use the ribbon bar buttons when a protected document is opened or the rich text editor is read-only. 

Use attached to reproduce. 

Using the RadDocumentEditor class, the users can change the margin of the current section. However, there isn't a method allowing them to change the default section margin of the document. 

Use attached to reproduce (the orientation must be set at design time)

Workaround:

Set it in code:

commandBarToggleButton2.Orientation = Orientation.Vertical

The issue can be observed in themes having shadows:

- Material 

- Fluent

The issue can be reproduced on a touch device after performing zoom in and zoom out

ChartPanZoomController panZoomController = new ChartPanZoomController();
panZoomController.PanZoomMode = ChartPanZoomMode.Both;
this.radChartView1.Controllers.Add(panZoomController);

 

Currently, the event arguments do not expose the data item.

ArgumentNullExceptionn in the RadPropertyValuesCollection class.

The issue can be reproduced by setting the AssociatedControl property in the designer and later at run-time.

Use attached to reproduce. Broken in version 2018.3.1016.40

Workaround:
private Size minSizeState;
private Size maxSizeState;
protected override void HandleDpiChanged()
{
    //base.HandleDpiChanged();

    float scaleFactor = 1f;

    if (this.oldDpi != 0)
    {
        scaleFactor = (float)this.currentDpi / this.oldDpi;
    }
    else if (this.oldDpi == 0) //Form shown for the first time.
    {
        scaleFactor = (float)this.currentDpi / 96f;
    }

    if (scaleFactor == 1f)
    {
        return;
    }

    this.maxSizeState = this.MaximumSize;
    this.minSizeState = this.MinimumSize;
    this.MinimumSize = Size.Empty;
    this.MaximumSize = Size.Empty;
    
    this.Scale(new SizeF(scaleFactor, scaleFactor));
   
    this.MinimumSize = TelerikDpiHelper.ScaleSize(this.minSizeState, new SizeF(scaleFactor, scaleFactor));
    this.MaximumSize = TelerikDpiHelper.ScaleSize(this.maxSizeState, new SizeF(scaleFactor, scaleFactor));

}

When RadRichTextBox.IsReasdOnly is true, RadRichTextBox.CommandExecuting is not raised when the user double clicks the header or footer area.

 The scroll in the SuggestedActionsElement cannot be made visible, one can scroll only with the mouse. Introduce a property so there is an indication that additional items are available.

In addition, the CreateChatElement in RadChat class should be made virtual. 

How to reproduce: 

this.radDiagram1.RoutingService.Router = new Telerik.Windows.Diagrams.Core.OrgTreeRouter() { TreeLayoutType = Telerik.Windows.Diagrams.Core.TreeLayoutType.TipOverTree };

this.radDiagram1.RouteConnections = true;

When there are no data rows in the grid the new row is current and the message is not displayed. In some themes, the grid looks like there is a single row which is confusing to the end users.
