Hello Steven,
MaskedTextBox works only with string values, hence the "45.77" value is formatted as string (from left to right) and that is why the displayed value is "457.7".
In order to accomplish your goal, you will need to pad the value before setting it to the widget. In other words, you will need to create " 45.77" (notice the space) value before setting to the widget.
