TextBox.AutoSize Property (Outlook Forms Script)
Returns or sets a Boolean that specifies whether an object automatically resizes to display its entire contents. Read/write.
expression A variable that represents a TextBox object.
True to automatically resize the control to display its entire contents. False to keep the size of the control constant; contents are clipped when they exceed the area of the control (default).
For controls without captions, this property specifies whether the control automatically adjusts to display the information stored in the control. In a ComboBox, for example, setting AutoSize to True automatically sets the width of the display area to match the length of the current text.
If you manually change the size of a control while AutoSize is True, the manual change overrides the size previously set by AutoSize.
For a single-line TextBox, setting AutoSize to True automatically sets the width of the display area to the length of the text in the text box.
For a multiline TextBox that contains no text, setting AutoSize to True automatically displays the text as a column. The width of the text column is set to accommodate the widest letter of that font size. The height of the text column is set to display the entire text of the TextBox.
For a multiline TextBox that contains text, setting AutoSize to True automatically enlarges the TextBox vertically to display the entire text. The width of the TextBox does not change.
