The method "ClearValue" on Span object is gone in Q3

[hwsoderlund]

Code like the following does not work anymore:

private void HtmlDataProvider_SetupDocument(object sender, SetupDocumentEventArgs e)
{
    foreach (Span span in e.Document.EnumerateChildrenOfType<Span>())
    {
        span.ClearValue(Span.FontSizeProperty);
        span.ClearValue(Span.FontFamilyProperty);
        span.ClearValue(Span.FontStyleProperty);
        span.ClearValue(Span.FontWeightProperty);
    }
}

I have replaced it with the following:

private void HtmlDataProvider_SetupDocument(object sender, SetupDocumentEventArgs e)
{
    foreach (Span span in e.Document.EnumerateChildrenOfType<Span>())
    {
        if (span.Style != null)
        {
            span.Style.ClearPropertyValue(Span.FontSizeProperty);
            span.Style.ClearPropertyValue(Span.FontFamilyProperty);
            span.Style.ClearPropertyValue(Span.FontStyleProperty);
            span.Style.ClearPropertyValue(Span.FontWeightProperty);
        }
    }
}

Is this the correct way to solve the issue?

Best regards,

Hello Henrik,

We had made the ClearValue method internal, as we have thought that it is not used. We will make sure to make it public again in the internal build next week.

For the time being, you can use the following approach, which has the same effect:

private void HtmlDataProvider_SetupDocument(object sender, SetupDocumentEventArgs e)
{
    foreach (Span span in e.Document.EnumerateChildrenOfType<Span>())
    {
        span.GetStyleProperty(Span.FontSizeProperty).ClearValue();
        span.GetStyleProperty(Span.FontFamilyProperty).ClearValue();
        span.GetStyleProperty(Span.FontStyleProperty).ClearValue();
        span.GetStyleProperty(Span.FontWeightProperty).ClearValue();
    }

Kind regards,
