change font during loading

[Tom]

Hi,

Museo font looks different than in word. It is possibile to change only paragraphs with "museo" font to for example "arial" during loading document?

Hello Tom,

In order to replace a particular FontFamily with another when a new document is loaded you can use the RadRichTextBox.DocumentChanged event:

<telerik:RadRichTextBox LayoutMode="Paged" DocumentChanged="editor_DocumentChanged"/>

In its handler you could iterate all RadDocument Styles and Spans and if their FontFamily is Museo change it to Arial. Here is a code snippet demonstrating how to change all spans and styles that have "Comic Sans MS" FontFamily to use "Arial" FontFamily:

private void editor_DocumentChanged(object sender, EventArgs e)
{
    var rtb = sender as RadRichTextBox;
    var doc = rtb.Document;
    foreach (StyleDefinition sd in doc.StyleRepository.Where(sd => sd.SpanProperties.FontFamily.Source == "Comic Sans MS"))
    {
        sd.SpanProperties.FontFamily = new FontFamily("Arial");
    }

    foreach (Span sp in doc.EnumerateChildrenOfType<Span>().Where(sp => sp.FontFamily.Source == "Comic Sans MS"))
    {
        sp.FontFamily = new FontFamily("Arial");
    }

    if (doc.Style.SpanProperties.FontFamily.Source == "Comic Sans MS")
    {
        doc.Style.SpanProperties.FontFamily = new FontFamily("Arial");
    }
}

Hope this helps.
