    NuGet Package: DevExpress.Blazor.RichEdit

    Declaration

    public ValueTask ShowAllFieldCodesAsync(
        bool doInAllSubDocuments = false,
        CancellationToken cancellationToken = default(CancellationToken)
    )

    Optional Parameters

    Name Type Default Description
    doInAllSubDocuments Boolean False

    true to display field codes in all sub-documents; false to display field codes in the current sub-document only.

    cancellationToken CancellationToken null

    Returns

    Type Description
    ValueTask

    A structure that stores an awaitable result of an asynchronous operation.

    Remarks

    A field has the {Code}Result> structure in the text buffer, for instance, {DATE}11/2/2020>. The Code specifies how the Result should be calculated when the field is updated.

    The Rich Text Editor can display a field as a code or result. Call the ShowAllFieldCodesAsync(Boolean) method to display fields as field codes, or call the ShowAllFieldResultsAsync(Boolean, CancellationToken) method to display fields as field results.

    <DxRichEdit @ref="@richEdit" />
    
    @code {
        DxRichEdit richEdit;
        Document documentAPI;
        @* ... *@
        /* 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;
                @* ... *@
                await documentAPI.Fields.ShowAllFieldResultsAsync();
                await documentAPI.Fields.ShowAllFieldCodesAsync();
                @* ... *@
            }
            catch (OperationCanceledException e) {
                Console.WriteLine($"{nameof(OperationCanceledException)} thrown with message: {e.Message}");
            }
    }
    

    Use a field’s IsShowCode property to get whether the field’s code or result is visible. Call the ToggleViewAsync(Field, CancellationToken) method to change the view mode of a field.
