Hallo,

 

I was using "Controldefault" theme and I got such an error message on laptops and desctops with smaller resolution when pointing to the gridview control:

See the end of this message for details on invoking 
just-in-time (JIT) debugging instead of this dialog box.

************** JIT Debugging **************
To enable just-in-time (JIT) debugging, the .config file for this
application or computer (machine.config) must have the
jitDebugging value set in the system.windows.forms section.
The application must also be compiled with debugging
enabled.

For example:

<configuration>
    <system.windows.forms jitDebugging="true" />
</configuration>

When JIT debugging is enabled, any unhandled exception
will be sent to the JIT debugger registered on the computer
rather than be handled by this dialog box.

At the same time on desctops with full HD everything was OK. I solved my problem selecting "Windows7" theme but I don't think it is a normal situation so I decided to inform You.

I use Visual Studio 2019 but I was unable to choose it from the list to finish the ticket.

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. 

Workaround: 

How to reproduce: 

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

this.radDiagram1.RouteConnections = true;

 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. 

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

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));

}

I used RadPageView under the theme "VisualStudio2012LightTheme" .

The ViewMode of RadPageview is Stack.

I wanted to change the font size of page header in runtime but it was not workable.

If I changed the theme to VisualStudio2012DarkTheme or Office2013LightTheme, it worked fine.

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

ArgumentNullExceptionn in the RadPropertyValuesCollection class.

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

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);

 

The issue can be observed in themes having shadows:

- Material 

- Fluent

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

Workaround:

Set it in code:

commandBarToggleButton2.Orientation = Orientation.Vertical

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