Here is a part of the highlighted document:

 public RadForm1() 
        {
            RadMapElement.VisualElementFactory = new MyMapVisualElementFactory();
            InitializeComponent();
        } 

Please refer to the attached sample project and follow the steps illustrated in the provided gif file.

Workaround:

        public RadForm1()
        {
            InitializeComponent();

            this.radPageView1.SelectedPageChanged += radPageView1_SelectedPageChanged;
        }

        private void radPageView1_SelectedPageChanged(object sender, EventArgs e)
        {
            if (this.radPageView1.SelectedPage != this.radPageViewPage1)
            {
                SelectionMiniToolBar selectionMiniToolBar = this.radRichTextEditor1.RichTextBoxElement.SelectionMiniToolBar as SelectionMiniToolBar;
                if (selectionMiniToolBar != null)
                {
                    selectionMiniToolBar.Hide();
                }
            }
        }

The performance of the DayView when the control is bound to a large number of recurring appointments and it is grouped by resources needs to be improved.

How to reproduce:

private void RadForm1_Load(object sender, EventArgs e)
{
    this.radWebCam1.TakeSnapshot();
}

Workaround:

public class CustomWebCam : RadWebCam
{
    public override void TakeSnapshot()
    {
        FieldInfo fi = typeof(RadWebCam).GetField("player", BindingFlags.NonPublic | BindingFlags.Instance);
        object value = fi.GetValue(this);

        if (value == null)
        {
            return;
        }

        PropertyInfo propertyInfo = value.GetType().GetProperty("EvrVideoDisplay", BindingFlags.NonPublic | BindingFlags.Instance);
        value = propertyInfo.GetValue(value, null);

        if (value == null)
        {
            return;
        }

        base.TakeSnapshot();
    }
}

Currently, RadFileDialogs uses a RadAutoCompleteBox for specifying the folder/file name. It would be nice to have a drop down with recent files:

Similar to RadMulticolumnComboBox but it should allow multiple items to be checked. Please refer to RadDropDownList and RadCheckedDropDownList. 

Workaround: 

To reproduce:

 radMaskedEditBox1.MaskedEditBoxElement.ContextMenuEnabled = true;

Workaround:

            this.radChat1.ChatElement.InputTextBox.TextBoxItem.TextBoxControl.Multiline = true;
            this.radChat1.ChatElement.InputTextBox.ButtonsStack.Children.Remove(this.radChat1.ChatElement.ShowToolbarButtonElement);
            this.radChat1.ChatElement.InputTextBox.ButtonsStack.Children.Remove(this.radChat1.ChatElement.SendButtonElement);
            StackLayoutElement stack = new StackLayoutElement();
            stack.MinSize = new Size(0, 60);
            this.radChat1.ChatElement.InputTextBox.Parent.Children.Add(stack);
            this.radChat1.ChatElement.InputTextBox.Parent.Children.Remove(this.radChat1.ChatElement.InputTextBox);
            stack.StretchHorizontally = true;
            stack.Orientation = Orientation.Horizontal;
            stack.Children.Add(this.radChat1.ChatElement.InputTextBox);
            stack.Children.Add(this.radChat1.ChatElement.ShowToolbarButtonElement);
            stack.Children.Add(this.radChat1.ChatElement.SendButtonElement);
            this.radChat1.ChatElement.ShowToolbarButtonElement.StretchHorizontally = false;
            this.radChat1.ChatElement.SendButtonElement.StretchHorizontally = false;

I have tried this code. It removes the item from list if we enter a letter first, then key down. But if we select an item then just press key down same item will be shown in the list.

I am working on a Windows Forms Application that load and print PDF document then unload that document  and load new one, but when i call unloadDocument() no new document was loaded :

                   RadPdfViewer rViewer = new RadPdfViewer();
                    rViewer.DocumentLoaded += RViewer_DocumentLoaded;
                    rViewer.LoadDocument(Filepath);
                    rViewer.LoadElementTree();
                    Application.DoEvents();
                    rViewer.PdfViewerElement.StopWaiting();
                    if (rViewer.IsLoaded)
                    { rViewer.UnloadDocument(); }

after unloadde the document i cannot load new PDF doccument?
