Hi,

I'm using version 5.2.7.

On the RichTextBox, the property RichTextBox.SelectionStyle.Family seems to always return "Portable User Interface" and not the font family name.  Do you know if I am doing something wrong?

Many thanks,

Adrian

Hi Adrian,

The RichTextBox.SelectionStyle reflects the current selection style at the cursor.  I have tested this and the font family is updated correctly, both here and in the online demo.  Can you provide the code you are using when you reference this property?  Are you using the SelectionChanged event?

Thanks!

Hi Dan,

Thanks for the help...

The control in my Xaml is defined as:

<liquid:RichTextBox x:Name="BodyRichTextBox" SelectionChanged="BodyRichTextBox_SelectionChanged"

                                    AutoWrap="True" EnableContextMenu="True"

                                    HorizontalScrollBarVisibility="Disabled" VerticalScrollBarVisibility="Visible"

                                    LinkClicked="BodyRichTextBox_LinkClicked"

                                    GotFocus="BodyRichTextBox_GotFocus"

                                    Grid.Row="11" Grid.Column="1" Grid.ColumnSpan="2" />

And my SelectionChanged event handler and the involved methods (fairly similar to your main example) read:

        private void BodyRichTextBox_SelectionChanged(object sender, RichTextBoxEventArgs e)

        {

            BoldButton.IsSelected = false;

            if (BodyRichTextBox.SelectionStyle.Weight == FontWeights.Bold)

            {

                BoldButton.IsSelected = true;

            }

            ItalicButton.IsSelected = false;

            if (BodyRichTextBox.SelectionStyle.Style == FontStyles.Italic)

            {

                ItalicButton.IsSelected = true;

            }

            UnderlineButton.IsSelected = false;

            if (BodyRichTextBox.SelectionStyle.Decorations == TextDecorations.Underline)

            {

                UnderlineButton.IsSelected = true;

            }

            this.supressFontEvents = true;

            this.SetStyleButtons();

            this.SetFontComboBoxes();

            this.supressFontEvents = false;

        }

        private void SetFontComboBoxes()

        {

            this.SetComboBox(FontFamilyComboBox, BodyRichTextBox.SelectionStyle.Family);

            this.SetComboBox(FontSizeComboBox, BodyRichTextBox.SelectionStyle.Size.ToString());

            this.SomeText.Text = BodyRichTextBox.SelectionStyle.Family.ToString();

        }

        private void SetComboBox(ComboBox comboBox, string value)

        {

            if (value != null)

            {

                foreach (ComboBoxItem item in comboBox.Items)

                {

                    if (item.Content.ToString().ToUpper(CultureInfo.InvariantCulture) ==

                        value.ToUpper(CultureInfo.InvariantCulture))

                    {

                        comboBox.SelectedItem = item;

                        break;

                    }

                }

            }

        }

        private void SetStyleButtons()

        {

            this.SetButton(BoldButton);

            this.SetButton(ItalicButton);

            this.SetButton(UnderlineButton);

        }

        private void SetButton(IconButton button)

        {

            if (button.IsSelected)

            {

                button.Background = new SolidColorBrush(Color.FromArgb(255, 255, 0, 0));

            }

            else

            {

                button.Background = new SolidColorBrush(Color.FromArgb(255, 0, 0, 0));

            }

        }

Many thanks,

Adrian

Actually, I think I've spotted it now.  It seems to be that 'Portable User Interface' is anything selected that hasn't been created as a particular font.  If I can somehow put the RichTextBox into a default font, it might fix this.

I just added the properties FontFamily="Arial" FontSize="11" as default properties to my RichTextBox.  After the Load, there is then no text without a valid SelectionStyle.Family property.

Cheers,

Adrian
