Namespace: DevExpress.Blazor.RichEdit

Assembly: DevExpress.Blazor.RichEdit.v24.2.dll

NuGet Package: DevExpress.Blazor.RichEdit

Declaration

public Interval ResultInterval { 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 ResultInterval property to get the text buffer interval that contains the field’s result.

The following example shows how you can use the ResultInterval property to delete a field but keep it result:

<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;
            @* ... *@
            // Creates and updates a DATE field
            Field newField = await documentAPI.Fields.CreateAsync(10, "DATE");
            await documentAPI.Fields.UpdateAsync(newField);
            // Gets the field result of the updated field
            newField = await documentAPI.Fields.GetAsync(newField.Index);
            TextSpan fieldResult = await documentAPI.GetTextSpanAsync(newField.ResultInterval);
            // Deletes the field
            await documentAPI.RemoveAsync(newField.Interval);
            // Inserts the field result
            await documentAPI.AddTextAsync(newField.Interval.Start, fieldResult.Text);
            @* ... *@
        }
        catch (OperationCanceledException e) {
            Console.WriteLine($"{nameof(OperationCanceledException)} thrown with message: {e.Message}");
        }
}

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