When a document is imported from HTML, we set locally to the span elements Times New Roman nevertheless it is not declared anywhere. This breaks the document view if for example we decide to change the RadDocument's default font family or even the NormalWeb style's font. The same applies for the font size as well.
Workaround: Clear the FontFamily property after import
foreach (Span span in this.radRichTextBox.Document.EnumerateChildrenOfType<Span>())
{
span.GetStyleProperty(Span.FontFamilyProperty).ClearValue();
span.GetStyleProperty(Span.FontSizeProperty).ClearValue();
}
Steps to reproduce:
1. Import the following html:
this.radRichTextBox.Document = new HtmlFormatProvider().Import(@"<h1>Hello</h1><h2>World</h2><p>Lorem ipsum<p>");
2. Set the document's default font family to Comic Sans MS:
this.radRichTextBox.Document.Style.SpanProperties.FontFamily = new FontFamily("Comic Sans MS");
Observe: The font in the document is Times New Roman
Expected: The font should be Comic Sans MS
The colspan="0" has special meaning according to the HTML specification http://www.w3.org/TR/html401/struct/tables.html:
-------------------
colspan = number [CN]
This attribute specifies the number of columns spanned by the current cell. The default value of this attribute is one ("1"). The value zero ("0") means that the cell spans all columns from the current column to the last column of the column group (COLGROUP) in which the cell is defined.
-------------------
Workaround: Preprocess the HTML, and delete all occurrences of colspan="0".
Add Korean language to your machine:
Then type 'rkskekfk'. The expected symbols are: "가나다라". However, if you try selecting the entered text, the last symbol disappears:
To reproduce:
this.radRichTextEditor1.Text = null;
If you remove the last span of a paragraph (on a measured document), using the inline collection, a NullReferenceException is thrown.
As a workaround: either make sure the manipulation happens on a non-measured document, or remove the span by using the RichTextEditor's API:
this.radRichTextEditor.Document.Selection.AddDocumentElementToSelection(span);
this.radRichTextEditor.Delete(false);
Open the Demo application >> RichTextEditor>> First Look example and open and empty document. Keep a random key pressed. You are expected to observe delayed text input:
For example, type 'p' in Telugu - 'జ', followed by 'ో' - they are combined in new grapheme - 'జో', or paste the following Thai grapheme: ชื
UI correctly visualizes this, but:
- Text measuring assumes that the grapheme width is equal to the sum of the widths of its parts (characters), which is not correct. Selection and caret position are scrambled because of this.
- There are document positions between the grapheme parts (characters), but shouldn't.
- When the caret is before the grapheme, deleting with "Delete" key deletes the grapheme in multiple steps (character by character), but should delete it in single step. Deleting with "Backspace" works correctly.
- There are some unsupported combinations in some languages. For example in Thai, typing 'z' then 'y' will produce grapheme, but typing 'w' then 'y' will not produce grapheme, and the 'y' should be ignored.
MS Word offers "Go To" option in its Find and Replace dialog:
It is reasonable to add similar scrolling behavior when navigating in document, programatic scrolling and GoTo~() methods.
In the Fluent theme, the Font Size Dropdown of the SelectionMiniToolBar is not wide enough.
This is the used code snippet:
static void Main(string[] args)
{
Telerik.WinForms.Documents.Model.RadDocument templateDocument = GetDocument("Template.rtf");
Telerik.WinForms.Documents.Model.RadDocument contentDocument = GetDocument("Content.rtf");
Telerik.WinForms.Documents.Model.Merging.InsertDocumentOptions options = new Telerik.WinForms.Documents.Model.Merging.InsertDocumentOptions();
options.ConflictingStylesResolutionMode = Telerik.WinForms.Documents.Model.Merging.ConflictingStylesResolutionMode.RenameSourceStyle;
options.InsertLastParagraphMarker = true;
Telerik.WinForms.Documents.Model.RadDocumentEditor templateEditor = new Telerik.WinForms.Documents.Model.RadDocumentEditor(templateDocument);
templateEditor.InsertFragment(new Telerik.WinForms.Documents.Model.DocumentFragment(contentDocument));
string mergedDocumentFilePath = "MergeDocumentsWithRichTextEditor.rtf";
File.Delete(mergedDocumentFilePath);
WriteDocToFile(templateDocument, mergedDocumentFilePath);
}
private static Telerik.WinForms.Documents.Model.RadDocument GetDocument(string rtfFilePath)
{
Telerik.WinForms.Documents.Model.RadDocument document = null;
var rtfImporter = new Telerik.WinForms.Documents.FormatProviders.Rtf.RtfFormatProvider();
using (Stream stream = File.OpenRead(rtfFilePath))
{
document = rtfImporter.Import(stream);
}
return document;
}
private static void WriteDocToFile(Telerik.WinForms.Documents.Model.RadDocument doc, string filename)
{
var rtfExporter = new Telerik.WinForms.Documents.FormatProviders.Rtf.RtfFormatProvider();
string rtfText = rtfExporter.Export(doc);
File.WriteAllText(filename, rtfText);
Process.Start(filename);
}Observed result:
Expected result: keep the After spacing as it is in the original documents.
