Examples

The following XAML example shows how to bind a combo box to the FontSize property using GetFontSizes to fill the combo box with available font sizes.

…
xmlns:tx="clr-namespace:TXTextControl.WPF;assembly=TXTextControl.WPF"
…
<Window.Resources>
    <tx:MeasureConverter Unit="Point" Decimals="1" x:Key="twipsConv" />
</Window.Resources>
…
<ComboBox
    Name="cbFontSize"
    IsEditable="True"
    IsReadOnly="True"
    Width="50"
    DropDownOpened="cbFontSize_DropDownOpened"
    Text="{Binding
    ElementName=textControl1,
    Path=InputFormat.FontSize,
    Converter={StaticResource twipsConv}}" />

private void cbFontSize_DropDownOpened(object sender, EventArgs e) {
    cbFontSize.ItemsSource = textControl1.InputFormat.GetFontSizes();
}

Private Sub cbFontSize_DropDownOpened(sender As Object, e As EventArgs)
    cbFontSize.ItemsSource = textControl1.InputFormat.GetFontSizes()
End Sub

The following example changes the formatting applied to text entered at the end of a document by using InputFormat.GetFontSizes.

textControl.Text = "Project summary";
textControl.InputPosition = new InputPosition(textControl.Text.Length);
InputFormat inputFormat = textControl.InputFormat;

string[] results = inputFormat.GetFontSizes("Arial");
foreach (string text in results)
{
    Console.WriteLine(text);
}

textControl.Text = "Project summary"
textControl.InputPosition = New InputPosition(textControl.Text.Length)
Dim inputFormat As InputFormat = textControl.InputFormat

Dim results As String() = inputFormat.GetFontSizes("Arial")
For Each text As String In results
    Console.WriteLine(text)
