Namespace: DevExpress.Blazor.RichEdit

Assembly: DevExpress.Blazor.RichEdit.v21.2.dll

NuGet Package: DevExpress.Blazor.RichEdit

Declaration

public Interval CodeInterval { get; }

Property Value

Type	Description
Interval	The text buffer interval.

Remarks

A field has the {Code}Result> structure in the text buffer, for instance, {DATE}11/2/2020>. Use the CodeInterval property to get the text buffer interval that contains the field code.

The following example shows how you can use the CodeInterval property to update only FILLIN fields:

<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 cancelled. */
        try {
            documentAPI = richEdit.DocumentAPI;
            @* ... *@
            IReadOnlyList<Field> fields = await documentAPI.Fields.GetAllAsync();
            foreach (Field field in fields) {
                TextSpan fieldCode = await documentAPI.GetTextSpanAsync(field.CodeInterval);
                if (fieldCode.Text.Contains("FILLIN"))
                    await documentAPI.Fields.UpdateAsync(field);
            }
            @* ... *@
        }
        catch (OperationCanceledException e) {
            Console.WriteLine($"{nameof(OperationCanceledException)} thrown with message: {e.Message}");
        }
}

The ResultInterval property allows you to get the text buffer interval that contains the field’s result. Use a field’s Interval property to get an entire field interval.
