Workaround use the following code to programatically toggle the spell check mode: RadRibbonBarGroup spellCheckGroup = ((RibbonTab)richTextEditorRibbonBar1.CommandTabs[0]).Items[3] as RadRibbonBarGroup; RadToggleButtonElement toggleButton = spellCheckGroup.Items[1] as RadToggleButtonElement; if (this.radRichTextEditor1.IsSpellCheckingEnabled) { toggleButton.CheckState = CheckState.Unchecked; } else { toggleButton.CheckState = CheckState.Checked; }
Due to a namespace conflict, projects which reference Telerik.WinControls.RichTextBox.dll and target .NET 4.5 or above, cannot be built successfully if they are using some of the conflicting types. The conflict comes from the ICommand interface (https://msdn.microsoft.com/en-us/library/system.windows.input.icommand%28v=vs.110%29.aspx) which was moved from PresentationCore.dll to System.dll in .NET 4.5.
Workaround: string match = "www.telerik.com"; string text = File.ReadAllText("..\\..\\test.html"); text = text.Replace(match, "http://" + match); File.WriteAllText("..\\..\\test.html", text);

Workaround: public partial class Form1 : Form { private Telerik.WinForms.RichTextEditor.RichTextBoxUI.Dialogs.SpellCheckingDialog spellDlg; public Form1() { InitializeComponent(); } private void radButton1_Click(object sender, EventArgs e) { this.spellDlg = new Telerik.WinForms.RichTextEditor.RichTextBoxUI.Dialogs.SpellCheckingDialog(); Telerik.WinForms.Documents.UI.Extensibility.SpellCheckingUIManager manager = new Telerik.WinForms.Documents.UI.Extensibility.SpellCheckingUIManager(this.radRichTextEditor1.RichTextBoxElement); FieldInfo fi = this.spellDlg.GetType().GetField("suggestionsListBox", BindingFlags.NonPublic | BindingFlags.Instance); RadListControl suggestionListBox = fi.GetValue(this.spellDlg) as RadListControl; suggestionListBox.DataBindingComplete -= suggestionListBox_DataBindingComplete; suggestionListBox.DataBindingComplete += suggestionListBox_DataBindingComplete; this.spellDlg.ShowDialog(manager, this.radRichTextEditor1.RichTextBoxElement); } private void suggestionListBox_DataBindingComplete(object sender, ListBindingCompleteEventArgs e) { if (((RadListControl)sender).Items.Count == 0) { FieldInfo fiBtnChange = this.spellDlg.GetType().GetField("buttonChange", BindingFlags.NonPublic | BindingFlags.Instance); RadButton btnChange = fiBtnChange.GetValue(this.spellDlg) as RadButton; btnChange.Enabled = false; FieldInfo fiBtnChangeAll = this.spellDlg.GetType().GetField("buttonChangeAll", BindingFlags.NonPublic | BindingFlags.Instance); RadButton btnChangeAll = fiBtnChangeAll.GetValue(this.spellDlg) as RadButton; btnChangeAll.Enabled = false; } } }
To reproduce: public Form1() { InitializeComponent(); this.radRichTextEditor1.IsReadOnly = true; } Workaround: private void Form1_Load(object sender, EventArgs e) { this.radRichTextEditor1.IsReadOnly = true; Telerik.WinControls.RichTextEditor.UI.DocumentWebLayoutPresenter webLayoutPresenter = this.radRichTextEditor1.RichTextBoxElement.ActiveEditorPresenter as Telerik.WinControls.RichTextEditor.UI.DocumentWebLayoutPresenter; webLayoutPresenter.Caret.Width = 0; }

Currently, the scrollbars width is calculated only according to SystemInformation.VerticalScrollBarWidth. Workaround: class MyRTE : RadRichTextEditor { protected override void CreateChildItems(RadElement parent) { var rte = new MyRTEElement(); typeof(RadRichTextEditor).GetField("richTextBox", BindingFlags.NonPublic | BindingFlags.Instance).SetValue(this, rte); parent.Children.Add(rte); } } public class MyRTEElement : RadRichTextBox { protected override SizeF ArrangeOverride(SizeF finalSize) { base.ArrangeOverride(finalSize); System.Drawing.RectangleF finalRect = new System.Drawing.RectangleF(System.Drawing.PointF.Empty, finalSize); System.Drawing.RectangleF clientRect = finalRect; System.Drawing.RectangleF horizontalScrollRect = System.Drawing.RectangleF.Empty; System.Drawing.RectangleF verticalScrollRect = System.Drawing.RectangleF.Empty; System.Drawing.RectangleF presenterArea = clientRect; if (this.VerticalScrollBar.Visibility != Telerik.WinControls.ElementVisibility.Collapsed) { verticalScrollRect = new System.Drawing.RectangleF( new System.Drawing.PointF(finalRect.Right - this.VerticalScrollBar.Size.Width, finalRect.Top), new System.Drawing.SizeF(this.VerticalScrollBar.Size.Width, finalRect.Height)); } if (this.HorizontalScrollBar.Visibility != Telerik.WinControls.ElementVisibility.Collapsed) { horizontalScrollRect = new System.Drawing.RectangleF( new System.Drawing.PointF(finalRect.Left, finalRect.Bottom - this.HorizontalScrollBar.Size.Height), new System.Drawing.SizeF(finalRect.Width, this.HorizontalScrollBar.Size.Height)); if (this.VerticalScrollBar.Visibility != Telerik.WinControls.ElementVisibility.Collapsed) { horizontalScrollRect.Width -= this.VerticalScrollBar.Size.Width; verticalScrollRect.Height -= this.HorizontalScrollBar.Size.Height; } } presenterArea.Width -= verticalScrollRect.Width; presenterArea.Height -= horizontalScrollRect.Height; if (this.RightToLeft) { horizontalScrollRect = Telerik.WinControls.Layouts.LayoutUtils.RTLTranslateNonRelative(horizontalScrollRect, clientRect); verticalScrollRect = Telerik.WinControls.Layouts.LayoutUtils.RTLTranslateNonRelative(verticalScrollRect, clientRect); presenterArea = Telerik.WinControls.Layouts.LayoutUtils.RTLTranslateNonRelative(presenterArea, clientRect); } this.VerticalScrollBar.Arrange(verticalScrollRect); this.HorizontalScrollBar.Arrange(horizontalScrollRect); var contentPresenter = typeof(RadRichTextBox).GetField("contentPresenter", System.Reflection.BindingFlags.Instance | System.Reflection.BindingFlags.NonPublic).GetValue(this) as ContentControl; contentPresenter.Arrange(presenterArea); return finalSize; } protected override SizeF MeasureOverride(SizeF availableSize) { base.MeasureOverride(availableSize); System.Drawing.SizeF horizontalScrollSize = System.Drawing.SizeF.Empty; System.Drawing.SizeF verticalScrollSize = System.Drawing.SizeF.Empty; System.Drawing.SizeF presenterSize = availableSize; if (this.VerticalScrollBar.Visibility != Telerik.WinControls.ElementVisibility.Collapsed) { verticalScrollSize = new System.Drawing.SizeF(this.VerticalScrollBar.Size.Width, availableSize.Height); } if (this.HorizontalScrollBar.Visibility != Telerik.WinControls.ElementVisibility.Collapsed) { horizontalScrollSize = new System.Drawing.SizeF(availableSize.Width, this.HorizontalScrollBar.Size.Height); } presenterSize.Width -= verticalScrollSize.Width; presenterSize.Height -= horizontalScrollSize.Height; //presenterSize = base.GetClientRectangle(presenterSize).Size; this.VerticalScrollBar.Measure(verticalScrollSize); this.HorizontalScrollBar.Measure(horizontalScrollSize); var contentPresenter = typeof(RadRichTextBox).GetField("contentPresenter", System.Reflection.BindingFlags.Instance | System.Reflection.BindingFlags.NonPublic).GetValue(this) as ContentControl; contentPresenter.Measure(presenterSize); return availableSize; } }
To reproduce: use the code snippet below. Please refer to the attached screenshot. public Form1() { RichTextBoxLocalizationProvider.CurrentProvider = new MyRichTextBoxLocalizationProvider(); InitializeComponent(); } public class MyRichTextBoxLocalizationProvider : RichTextBoxLocalizationProvider { public override string GetLocalizedString(string id) { return base.GetLocalizedString(id); } } Workaround: Modify the XML file containing all the strings RichTextBoxLocalizationProvider.CurrentProvider = RichTextBoxLocalizationProvider.FromFile(@"C:\RichTextBoxStrings.xml");. You can download a XML file that contains all the currently used strings from here: http://www.telerik.com/docs/default-source/ui-for-winforms/richtextboxstrings.zip?sfvrsn=2
To reproduce: 1.Use the provided xml file in the following article: http://www.telerik.com/help/winforms/richtexteditor-localization.html and change these strings: "Documents_ParagraphPropertiesDialog_TextAlignment_Center": "Mittig"; "Documents_ParagraphPropertiesDialog_TextAlignment_Justify": "Block"; "Documents_ParagraphPropertiesDialog_TextAlignment_Left": "Links"; "Documents_ParagraphPropertiesDialog_TextAlignment_Right": "Rechts"; 2.Afterwards, specify the RichTextBoxLocalizationProvider.CurrentProvider by loading the modified file. 3.Run the application, select some paragraph and try to change its alignment. As a result when the ParagraphPropertiesDialog is opened, incorrect alignment text is displayed in the drop-down. If you select a new value a handled ArgumentException is thrown and the paragraph is not aligned at all. Workaround: use a custom ParagraphPropertiesDialog: public Form1() { RichTextBoxLocalizationProvider.CurrentProvider = RichTextBoxLocalizationProvider.FromFile(@"..\..\RichTextBoxStrings - Copy.xml"); InitializeComponent(); this.radRichTextEditor1.RichTextBoxElement.ParagraphPropertiesDialog = new CustomDialog(); } public partial class CustomDialog : ParagraphPropertiesDialog { public CustomDialog() { InitializeComponent(); FieldInfo fi = typeof(ParagraphPropertiesDialog).GetField("radButtonOK", BindingFlags.Instance | BindingFlags.NonPublic); RadButton btn = fi.GetValue(this) as RadButton; btn.MouseDown += btn_MouseDown; } protected override void OnLoad(EventArgs e) { base.OnLoad(e); if (selectedItem != null) { ButtonAlignement.Text = selectedItem.Text; } } public RadDropDownButton ButtonAlignement { get { FieldInfo fi = typeof(ParagraphPropertiesDialog).GetField("radDropDownButtonAlignement", BindingFlags.Instance | BindingFlags.NonPublic); RadDropDownButton radDropDownButtonAlignement = fi.GetValue(this) as RadDropDownButton; return radDropDownButtonAlignement; } } RadMenuItem selectedItem = null; RadDropDownButton radDropDownButtonAlignement = null; private void btn_MouseDown(object sender, MouseEventArgs e) { foreach (RadMenuItem item in ButtonAlignement.Items) { if (item.Text == ButtonAlignement.Text) { selectedItem = item; break; } } if (selectedItem != null) { ButtonAlignement.Text = selectedItem.Tag.ToString(); } } }
To reproduce: - Add some comments and try to navigate through them. - Try add or show/hide the comments while the cursor is in one of the comments. Workaround: Create a custom RichTextEditorRibbonBar and override the following methods: Public Class MyRichTextEditorRibbonBar Inherits RichTextEditorRibbonBar Protected Overrides Sub ButtonNewComment_Click(sender As Object, e As EventArgs) Dim command As New InsertCommentCommand(Me.AssociatedRichTextEditor.RichTextBoxElement) Me.ExecuteCommand(command) End Sub Protected Overrides Sub ButtonDeleteComment_Click(sender As Object, e As EventArgs) Dim command As New DeleteCommentCommand(Me.AssociatedRichTextEditor.RichTextBoxElement) Me.ExecuteCommand(command) End Sub Protected Overrides Sub ButtonPreviousComment_Click(sender As Object, e As EventArgs) Dim command As New GoToPreviousCommentCommand(Me.AssociatedRichTextEditor.RichTextBoxElement) Me.ExecuteCommand(command) End Sub Protected Overrides Sub ButtonNextComment_Click(sender As Object, e As EventArgs) Dim command As New GoToNextCommentCommand(Me.AssociatedRichTextEditor.RichTextBoxElement) Me.ExecuteCommand(command) End Sub Protected Overrides Sub ToggleButtonShowHideComments_ToggleStateChanged(sender As Object, args As StateChangedEventArgs) Dim command As New ToggleCommentsCommand(Me.AssociatedRichTextEditor.RichTextBoxElement) Me.ExecuteCommand(command) End Sub Protected Overrides Sub ButtonDeleteAllComments_Click(sender As Object, e As EventArgs) Dim command As New DeleteAllCommentsCommand(Me.AssociatedRichTextEditor.RichTextBoxElement) Me.ExecuteCommand(command) End Sub Protected Overrides Sub HandleDocumentCommandExecuted(document As RadDocument) MyBase.HandleDocumentCommandExecuted(document) Dim hasComments As Boolean = Me.AssociatedRichTextEditor.Document.EnumerateChildrenOfType(Of CommentRangeStart)().Count() > 0 Me.buttonPreviousComment.Enabled = hasComments Me.buttonNextComment.Enabled = hasComments Me.buttonDeleteComment.Enabled = hasComments Me.buttonDeleteAllComments.Enabled = hasComments End Sub End Class
When some commands are executed the RibbonUI is not updated. For example: private void radButton1_Click(object sender, EventArgs e) { ToggleCommentsCommand command = new ToggleCommentsCommand(radRichTextEditor1.RichTextBoxElement); command.Execute(); } Workaround: var button = ribbonBar1.GetType().GetField("toggleButtonShowHideComments", BindingFlags.Instance | BindingFlags.NonPublic).GetValue(this.ribbonBar1) as RadToggleButtonElement; button.ToggleState = (radRichTextEditor1.RichTextBoxElement.ShowComments == true) ? ToggleState.On : ToggleState.Off;
To reproduce: RadDocument document = new RadDocument(); Section section = new Section(); Paragraph p = new Paragraph(); Span span = new Span(); span.Text ="test" + Environment.NewLine + "test"; ReadOnlyRangeStart rangeStart = new ReadOnlyRangeStart(); ReadOnlyRangeEnd rangeEnd = new ReadOnlyRangeEnd(); rangeEnd.PairWithStart(rangeStart); p.Inlines.Add(rangeStart); p.Inlines.Add(span); p.Inlines.Add(rangeEnd); section.Blocks.Add(p); document.Sections.Add(section); this.radRichTextEditor1.Document = document; Workaround: add an empty span as last inline element in the paragraph: RadDocument document = new RadDocument(); Section section = new Section(); Paragraph p = new Paragraph(); Span span = new Span(); span.Text ="test" + Environment.NewLine + "test"; ReadOnlyRangeStart rangeStart = new ReadOnlyRangeStart(); ReadOnlyRangeEnd rangeEnd = new ReadOnlyRangeEnd(); rangeEnd.PairWithStart(rangeStart); p.Inlines.Add(rangeStart); p.Inlines.Add(span); p.Inlines.Add(rangeEnd); /////////////////////////////////////// Span emptySpan = new Span(); emptySpan.Text = " "; p.Inlines.Add(emptySpan); /////////////////////////////////////// section.Blocks.Add(p); document.Sections.Add(section); this.radRichTextEditor1.Document = document;
To reproduce: use the following code snippet and refer to the attached screenshot. Cells' width should be identical in both of the cases. RadDocument document = new RadDocument(); Section section = new Section(); Table t = new Table(); t.Borders = new TableBorders(new Border(2, Telerik.WinForms.Documents.Model.BorderStyle.Single, Color.Black)); TableRow r1 = new TableRow(); TableCell cell = new TableCell(); Paragraph p = new Paragraph(); Span s = new Span(); s.Text = "Header"; cell.ColumnSpan = 3; p.Inlines.Add(s); cell.Blocks.Add(p); cell.PreferredWidth = new TableWidthUnit(TableWidthUnitType.Percent, 100); r1.Cells.Add(cell); TableRow r2 = new TableRow(); TableCell cell11 = new TableCell(); Paragraph p11 = new Paragraph(); Span s11 = new Span(); s11.Text = "Cell1,1"; p11.Inlines.Add(s11); cell11.Blocks.Add(p11); cell11.PreferredWidth = new TableWidthUnit(TableWidthUnitType.Percent, 40); TableCell cell12 = new TableCell(); Paragraph p12 = new Paragraph(); Span s12 = new Span(); s12.Text = "Cell1,2"; p12.Inlines.Add(s12); cell12.Blocks.Add(p12); cell12.PreferredWidth = new TableWidthUnit(TableWidthUnitType.Percent, 10); TableCell cell13 = new TableCell(); Paragraph p13 = new Paragraph(); Span s13 = new Span(); s13.Text = "Cell1,3"; p13.Inlines.Add(s13); cell13.Blocks.Add(p13); cell13.PreferredWidth = new TableWidthUnit(TableWidthUnitType.Percent, 50); r2.Cells.Add(cell11); r2.Cells.Add(cell12); r2.Cells.Add(cell13); t.Rows.Add(r1); t.Rows.Add(r2); section.Blocks.Add(t); document.Sections.Add(section); this.radRichTextEditor1.Document = document; Workaround: do not specify the PreferredWidth proeprty for cells with ColumnSpan>1
Workaround: set the FormBorderStyle property to FixedSingle for the respective dialog. RadForm f = this.radRichTextEditor1.RichTextBoxElement.FontPropertiesDialog as RadForm; f.FormBorderStyle = System.Windows.Forms.FormBorderStyle.FixedSingle;
To reproduce: - Use the cut option in the context menu then dispose the rich text editor and collect the garbage. Workaround: Telerik.WinControls.RichTextEditor.UI.ContextMenu menu = textEditor.RichTextBoxElement.ContextMenu as Telerik.WinControls.RichTextEditor.UI.ContextMenu; textEditor.RichTextBoxElement.ContextMenu = null; RadDropDownMenu ddm = menu.GetType().GetField("radDropDownMenu", BindingFlags.NonPublic | BindingFlags.Instance).GetValue(menu) as RadDropDownMenu;
