CharacterProperties.HighlightColor Property

Specifies the highlight color of characters.

Namespace: DevExpress.Blazor.RichEdit

Assembly: DevExpress.Blazor.RichEdit.v24.1.dll

NuGet Package: DevExpress.Blazor.RichEdit

Declaration

public Color? HighlightColor { get; set; }

Property Value

Type	Description
Nullable<Color>	The highlight color or null if at least two different characters use different highlight colors.

Remarks

Use a text span’s HighlightColor or a table cell’s CharacterProperties.HighlightColor property to obtain the highlight color of characters in the span or cell. Call the TextSpan.ChangePropertiesAsync or TableCell.ChangePropertiesAsync method to change the highlight color of characters.

Note

The highlight color overlaps the background color.

The following example highlights all characters in a text span in yellow:

<DxRichEdit @ref="richEdit" />

@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");
            await characters.ChangePropertiesAsync(properties => {
                properties.HighlightColor = System.Drawing.Color.Yellow;
            });
        }
        catch (OperationCanceledException e) {
            Console.WriteLine($"{nameof(OperationCanceledException)} thrown with message: {e.Message}");
        }
    }
}
