How to: Position the Cursor at the Beginning or End of Text in a TextBox Control

The following Extensible Application Markup Language (XAML) code describes a TextBox control and assigns it a Name.

<TextBox
  Name="tbPositionCursor"
>
  Here is some text in my text box...
</TextBox>

To position the cursor at the beginning of the contents of a TextBox control, call the Select method and specify the selection start position of 0, and a selection length of 0.

tbPositionCursor.Select(0, 0);

To position the cursor at the end of the contents of a TextBox control, call the Select method and specify the selection start position equal to the length of the text content, and a selection length of 0.

tbPositionCursor.Select(tbPositionCursor.Text.Length, 0);
