When adding a new document to the same instance of a RichTextEditor, the UIProviderRegistry instance of the RichTextBox will keep a dictionary entry for a SectionLayoutBox that contains a reference to a non cleaned up WaterMarkUiProvider.

This SectionLayoutBox in turn has a reference to a DocumentLayoutBox (parent) which has a reference to an old document instance.

 

A new dictionary entry is added and (retained) for every document loaded.

 

Disposing the old document makes no difference.

 

 

Hi Sir,

We updated telerik and facing some issues with that.

in new update with rich text editor has new property called  MentionBox settings of that auto added in to designer code. 

which creates an error when we run the application.

following line is auto added.

mentionBox1.FocusedItemIndex = -1;

 

we have to comment every time after doing UI changes. and we need to check every time whether that line is commented or not. 

 

Please Help Us.

Thanks,

Ashish.

Provide an option to scale the watermark like in MS Word

Break style is lost when a html is reopened

Introduce support for the IF field. More info here: https://wordmvp.com/FAQs/MailMerge/MMergeIfFields

 

I just updated from 2021.1.326 to 2021.2.615 and suddenly the app hangs and eventually crashes.

The list format is not preserved when exporting to HTML

When exporting a single paragraph to HTML one empty span is added after the content. 

The CSS style names shouldn't contain non-ASCII characters and if present, they should be escaped. HtmlFormatProvider doesn't escape them while exporting and cannot properly import the generated file.

When I have an InlineImage in a horizontally centered paragraph, PrintPreview presents the image unevenly on the page. There should be the same space on left and right, as the page padding is the same all around. See the arrows indicated below:

Hi Team, 

We found an issue in Spell Check Feature in  RichTextEditor, the Spell Checking Dialog auto-correct the spelling issues on scroll without clicking on the "Change" button.

We are able to reproduce this in the Demo application. please have a look at the below screencast.

Thank you.

Show substitute image when the image from the document cannot be rendered 

Make the image loading async and consider reducing their size like MS Word

To reproduce: 

public RadForm1()
{
    InitializeComponent();
    radRichTextEditor1.CommandExecuted += RadRichTextEditor1_CommandExecuted; 
    radRichTextEditor1.ActiveDocumentEditorChanged += RadRichTextEditor1_ActiveDocumentEditorChanged;
}

private void RadRichTextEditor1_ActiveDocumentEditorChanged(object sender, Telerik.WinForms.Documents.UI.ActiveDocumentEditorChangedEventArgs e)
{
    e.OldActiveEditor.CommandExecuted -= RadRichTextEditor1_CommandExecuted;
    e.NewActiveEditor.CommandExecuted += RadRichTextEditor1_CommandExecuted;        
}

 
private void RadRichTextEditor1_CommandExecuted(object sender, Telerik.WinForms.Documents.RichTextBoxCommands.CommandExecutedEventArgs e)
{
    if (e.Command is InsertPictureCommand)
    {

        var imageInline = this.radRichTextEditor1.DocumentEditor.Document.CaretPosition.GetPreviousInline() as ImageInline;
        if (imageInline != null)
        {
            imageInline.Size = new Telerik.WinControls.RichTextEditor.UI.Size(50, 50);
        }
    }
}

When changing the theme to a dark theme the Rich text editor appears to have an issue converting the Styles tab as below. Expected to see conversion from light theme styles to dark themes styles.

According to the Office Open XML specification, the attributes must be used with the prefix of their namespace to ensure that the unique attribute is used. However, some tools generate invalid documents without that prefix. RadRichTextBox throws ArgumentException in such cases. Enable the control to handle similar scenarios without errors.

To reproduce the problem create new blank Word document (from MS Word). Hold Alt key and type 0268. You will see a letter Č (Latin letter C with caron). In Visual Studio create a Word-inspired project, and run it. Copy the text from Word document to the Telerik RTF editor. Now in Telerik RTF editor change the font of this letter to Algerian. I have Algerian font with my Office 2013, so I hope you'll have it too; you can use Symbol font instead of Algerian for the same result. My Algerian font does not support letter Č, so in Telerik RTF editor I will see a narrow empty box (also called "tofu") instead of letter Č.

One cannot paste when the AutomaticallyLoadFormatProviders property is false. Even if you register the format providers manually: 

public MainWindow()
{
    DocumentFormatProvidersManager.AutomaticallyLoadFormatProviders = false;
    DocumentFormatProvidersManager.RegisterFormatProvider(new HtmlFormatProvider());
    DocumentFormatProvidersManager.RegisterFormatProvider(new RtfFormatProvider());
    DocumentFormatProvidersManager.RegisterFormatProvider(new DocxFormatProvider());
    DocumentFormatProvidersManager.RegisterFormatProvider(new Telerik.Windows.Documents.FormatProviders.Xaml.XamlFormatProvider());
    InitializeComponent();
}

Bookmarks are not imported and missing from a specific document scenario.

Workaround: Import and then export the document using the WordsProcessing library and then open it with the editor.

Add support for embedded objects
