TextBox.SelectionLength Property

Definition

Namespace:

System.Windows.Controls

Assembly:

PresentationFramework.dll

Gets or sets a value indicating the number of characters in the current selection in the text box.

public:
 property int SelectionLength { int get(); void set(int value); };

public int SelectionLength { get; set; }

member this.SelectionLength : int with get, set

Public Property SelectionLength As Integer

Property Value

Int32

The number of characters in the current selection in the text box. The default is 0.

Exceptions

ArgumentOutOfRangeException

SelectionLength is set to a negative value.

Remarks

Getting this property returns the number of characters in the current selection. Setting this property adjusts the length of the current selection to the specified value, keeping the beginning of the selection fixed.

In general, when the specified selection length causes the selection to end in an invalid position (for example, between a carriage return and a new-line character, or inside a tag), the selection length automatically adjusts so that the resulting selection starts and ends in valid positions.
