Namespace: DevExpress.Blazor.RichEdit

NuGet Package: DevExpress.Blazor.RichEdit

C#
public class CharacterProperties :
    ICharacterProperties

The following members return CharacterProperties objects:

#Remarks

Pass a CharacterProperties object to the TextSpan.ChangePropertiesAsync method to set properties of all characters in a text span. You can customize individual character properties or call the CopyFrom(TextSpan) method to copy properties from another text span.

Pass a TableCellProperties object to the TableCell.ChangePropertiesAsync method to change table cell settings. The TableCellProperties.CharacterProperties setting allows you to change text formatting settings of a cell.

The following example copies character properties between two text spans:

Razor

@code {
    DxRichEdit richEdit;
    Document documentAPI;

    protected override async Task OnAfterRenderAsync(bool firstRender) {
        if (firstRender)
            try {
                await InitializeDocument();
            }
            catch (TaskCanceledException) { }
        await base.OnAfterRenderAsync(firstRender);
    }

    async Task InitializeDocument() {
    /* Surround the code that contains an asynchronous operation with a try-catch block to handle
    the OperationCanceledException. This exception is thrown when an asynchronous operation is canceled. */
        try {
            documentAPI = richEdit.DocumentAPI;
            TextSpan characters = await documentAPI.AddTextAsync("New Text");
            IReadOnlyList<Paragraph> paragraphs = await documentAPI.Paragraphs.GetAllAsync();
            foreach (Paragraph p in paragraphs) {
                TextSpan currentCharacters = await documentAPI.GetTextSpanAsync(p.Interval);
                await currentCharacters.ChangePropertiesAsync(properties => {
                    properties.CopyFrom(characters);
                });
            }
        }
        catch (OperationCanceledException e) {
            Console.WriteLine($"{nameof(OperationCanceledException)} thrown with message: {e.Message}");
