    TextBoxExt textBoxExt1 = new TextBoxExt();
textBoxExt1.Text = "textboxext1";
this.Controls.Add(textBoxExt1);
    Dim textBoxExt1 As New TextBoxExt()

textBoxExt1.MaximumSize = new System.Drawing.Size(267, 104);
textBoxExt1.MaximumSize = New System.Drawing.Size(267, 104)
textBoxExt1.MinimumSize = New System.Drawing.Size(267, 104)

Multiline

The TextBoxExt control can be customized to display multiline text using the following properties:

  • Multiline - Spans the text of the edit control to more than one line.
  • WordWrap - Indicates whether the lines are automatically word-wrapped for the multiline edit controls.
  • ScrollBars - Enables scrollbars when the text overflows the size of the text box. The available options are horizontal, vertical, both, and none.
textBoxExt1.Multiline = true;
textBoxExt1.WordWrap = true;
textBoxExt1.ScrollBars = System.Windows.Forms.ScrollBars.Vertical;
textBoxExt1.Multiline = True
textBoxExt1.WordWrap = True
textBoxExt1.ScrollBars = System.Windows.Forms.ScrollBars.Vertical
