Gets or sets the content of the current selection in the text box.

Namespace:  System.Windows.Controls
Assembly:  System.Windows (in System.Windows.dll)

Syntax

'Declaration
Public Property SelectedText As String

public string SelectedText { get; set; }

<TextBox SelectedText="string"/>

Property Value

Type: System.String
The currently selected text in the text box. If no text is selected, the value is Empty.

Exceptions

Remarks

Getting this property returns a string copy of the current selection. Setting this property replaces the current selection with the specified string.

SelectedText can be used to replace the selected text or to insert new text at the cursor location if no text is selected.

Setting the SelectedText property raises the SelectionChanged event.

Examples

The following code example shows how you can use the SelectedText property.

Private Sub MyButton_Click(ByVal sender As Object, ByVal e As RoutedEventArgs)
    'Contents that are selected in MyTB1 are copied to MyTB2 
    MyTB2.Text = MyTB1.SelectedText
End Sub

private void MyButton_Click(object sender, RoutedEventArgs e)
{
    //Contents that are selected in MyTB1 are copied to MyTB2
    MyTB2.Text = MyTB1.SelectedText;
}
