Description

Gets or sets a value specifying whether the writung direction is left-to-right at the current input position. If text is selected, the property specifies this attribute for the whole selected text.

Syntax

public bool? LeftToRight { get; set; }

Public Property LeftToRight As Boolean?

Examples

The following XAML example binds the LeftToRight property to a ToggleButton:

<ToggleButton 
    Height="29"
    Name="buttonLeftToRight"
    IsChecked="{Binding ElementName=textControl1, Path=InputFormat.LeftToRight, Mode=TwoWay}">
    Left to Right</ToggleButton>

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

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

inputFormat.LeftToRight = true;
if (inputFormat.LeftToRight != null)
{
    Console.WriteLine("Input Format: Left To Right is available.");
}

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

inputFormat.LeftToRight = True
If inputFormat.LeftToRight IsNot Nothing Then
    Console.WriteLine("Input Format: Left To Right is available.")
End If

Remarks

The property returns null, if the text selection contains multiple paragraphs with mixed setting.
