If you have two RadGridView controls and you want to export both of the grids to a common file on two different sheets, it is suitable to use FileExportMode.NewSheetInExistingFile. However, when using the export overload to a stream doesn't respect the ExportMode.

Workaround: use exporting to a file:

            string exportFile = @"..\..\exportedData.xlsx";
            GridViewSpreadStreamExport spreadStreamExport = new GridViewSpreadStreamExport(this.radGridView1);
            spreadStreamExport.FileExportMode = FileExportMode.NewSheetInExistingFile;
            spreadStreamExport.ExportVisualSettings = false;
            spreadStreamExport.RunExport(exportFile, new SpreadStreamExportRenderer());

When I use the Crystal theme on the ribbonbar items disappear from the backstage view.

I found the same behavior on your demo also. So I'm giving you the steps to replicate the behavior there. When I switch to other themes the issue does not seem to happen.

1. Go to the Ribbonbar First Look demo.
2. Switch the theme to Crystal
3. Go to the Backstage view and just move the mouse or hover over the Print preview
4. All items will disappear. The only way to get them back is to switch to another theme.

Please let me know if I can provide any other information to help resolve this issue.

Thank you

Eddy

To reproduce:
- Hide the border and change the BackColor of the form. 
- Dock a MenuStrip to the top. 
- You will notice that there are 2 pixels on the left and right sides of the menu. 

Project is attached as well.

When you copy "Chang" and try to paste it in the editable area, it is not pasted even if the Clipboard data is a valid entry: 

        Me.RadMultiColumnComboBox1.DisplayMember = "ProductName"
        Me.RadMultiColumnComboBox1.ValueMember = "ProductID"
        Me.RadMultiColumnComboBox1.DataSource = ProductsBindingSource

        Me.RadMultiColumnComboBox1.AutoCompleteMode = AutoCompleteMode.Append
        Me.RadMultiColumnComboBox1.MultiColumnComboBoxElement.LimitToList = True

However, the context menu in the text box is available and you can paste even invalid value.

To reproduce:

public Form1()
{
    InitializeComponent();
    
    this.radScheduler1.ActiveViewType = SchedulerViewType.Timeline;
    Timescales scale = Timescales.Hours;
    this.radScheduler1.GetTimelineView().ShowTimescale(scale);

    Appointment app1 = new Appointment(DateTime.Today.AddHours(6), TimeSpan.FromMinutes(25), "A1");
    Appointment app2 = new Appointment(DateTime.Today.AddHours(6).AddMinutes(25), TimeSpan.FromMinutes(16), "A2");
    Appointment app3 = new Appointment(DateTime.Today.AddHours(6).AddMinutes(41), TimeSpan.FromMinutes(12), "A3");

    this.radScheduler1.Appointments.Add(app1);
    this.radScheduler1.Appointments.Add(app2);
    this.radScheduler1.Appointments.Add(app3); 

    this.radScheduler1.EnableExactTimeRendering = true;  
}


Workaround:

 this.radScheduler1.ElementProvider = new MyElementProvider(this.radScheduler1);

public class MyElementProvider : SchedulerElementProvider
{
    public MyElementProvider(RadScheduler scheduler) : base(scheduler)
    {
    }

    protected override T CreateElement<T>(SchedulerView view, object context)
    {
        if (typeof(T) == typeof(TimelineAppointmentsPresenter))
        {
            return new CustomTimelineAppointmentsPresenter(this.Scheduler, view, (SchedulerTimelineViewElement)context)as T;
        }
        return base.CreateElement<T>(view, context);
    }
}

public class CustomTimelineAppointmentsPresenter: TimelineAppointmentsPresenter
{
    public CustomTimelineAppointmentsPresenter(RadScheduler scheduler, SchedulerView view,
        SchedulerTimelineViewElement timelineViewElement) : base(scheduler, view, timelineViewElement)
    {
    }

    protected override void ResolveOverlappingAppointments(SizeF availableSize)
    {
        List<AppointmentElement> appointments = new List<AppointmentElement>();
        foreach (AppointmentElement element in this.AppointmentElements)
        {
            if (element.Visibility != ElementVisibility.Collapsed)
            {
                appointments.Add(element);
            }
        }

        appointments.Sort(new DateTimeComparer(this.Scheduler));
        List<AppointmentElement> arrangedAppointments = new List<AppointmentElement>();

        foreach (AppointmentElement appointment in appointments)
        {
            for (int i = 0; i < arrangedAppointments.Count; i++)
            {
                AppointmentElement otherAppointment = arrangedAppointments[i];

                if (otherAppointment == appointment)
                {
                    continue;
                }

                RectangleF rect = appointment.DesiredBounds;
                rect.Inflate(new SizeF(-2,-2));
                if (otherAppointment.DesiredBounds.IntersectsWith(rect))
                {
                    appointment.DesiredBounds.Y = otherAppointment.DesiredBounds.Bottom;
                    i = -1;

                    continue;
                }
            }

            arrangedAppointments.Add(appointment);
        }
    }
}

Hi,

Font size in ribbon does not change to the font size of custom style. 

See attached video and c# project.

Best regards,

Ziping Wang

To reproduce:
- Add ColumnGroupsViewDefinition and set ShowHeader to false. 
- Set AutoSizeRows to true.

Workaround:
Manually set the row height.
  ViewDefinition.ColumnGroups(0).Rows(0).MinHeight = 50

Use the following code snippet and try to edit the Height. You will notice that the sub-items' order is changed:

            RadPropertyStore store = new RadPropertyStore();
            PropertyStoreItem sizeItem = new PropertyStoreItem(typeof(System.Drawing.Size), "Size", new System.Drawing.Size(100, 25), "The size of the control in pixels.", "Layout");
            store.Add(sizeItem);

            this.radPropertyGrid1.SelectedObject = store;
            this.radPropertyGrid1.SortOrder = SortOrder.Ascending;
            this.radPropertyGrid1.PropertySort = PropertySort.Alphabetical;

To reproduce:
- Add RichTextEditorRuler and RichTextEditor to a form.
- Add some tab stops in the ruler and press the tab key.

Workaround:
void radRichTextEditor1_CommandExecuting(object sender, Telerik.WinForms.Documents.RichTextBoxCommands.CommandExecutingEventArgs e)
{
    if (e.Command is IncrementParagraphLeftIndentCommand)
    {
        e.Cancel = true;
        TabForwardCommand tabForward = new TabForwardCommand(this.radRichTextEditor1.RichTextBoxElement);
        tabForward.Execute();
    }
}

Follow the steps:

1.Create an application and add a RadRibbonForm with name RadRibbonForm1.

2. Create a new class with name RadRibbonForm1.Test.cs and make it partial. It should look like a form.

3. Double click the new class. It will open the designer and some code will be generated in the class which prevents the application from building. The attached gif file with RadRibbonForm illustrates better the specific steps.

The error is reproducible in the First look example of RadPivotGrid:

NOTE: This is my second attempt to get a response from the support team. I am paying for Priority Support, but the ticket below has gone unanswered:

https://feedback.telerik.com/winforms/1487329-popup-calendar-in-raddatetimepicker-does-not-scale-correctly-on-high-dpi-display

See attached screenshot. The popup calendar looks wrong when running on a display with 250% scaling. Surely, that's not correct. The calendar should not be so large and the fonts so small. Am I missing something? I have done all the other steps to enable High DPI support, and as you can see, the textbox area seems to scale fine.

Any ideas? And thanks for your help.

David

RadRichTextEditor renders the text with a little bigger characters spacing than RadRichTextBox and MS Word.
Note: this text spacing problem can be observed in other Telerik controls as well.
