Make text range invisible for printing

[Marcílio]

Its possible a read only text range turn invisible for printing? That is, a read only text range followed by a editable range. And, when sent to printer, print only the editable part (the read only part leave just a white space on the printed page).

Is that possible with the RadRichTextBox?

Hi,

One option would be to intercept the printing command, apply transparent fore color to parts of the document, print, and then undo the change, for example:

this.radRichTextBox.CommandExecuting += (sender, e) =>
{
    if (e.Command is PrintCommand)
    {
        var rangeStart = this.radRichTextBox.Document.EnumerateChildrenOfType<PermissionRangeStart>().First();

        this.radRichTextBox.BeginUndoGroup();
        this.radRichTextBox.Document.Selection.SelectAnnotationRange(rangeStart);
        this.radRichTextBox.ChangeTextForeColor(Colors.Transparent);
        this.radRichTextBox.EndUndoGroup();
    }
};

this.radRichTextBox.CommandExecuted += (sender, e) =>
{
    if (e.Command is PrintCommand)
    {
        this.radRichTextBox.Undo();
    }
};
