let's say that we have a multiline TextBox into which a collection of Lines is added. TextBox has a VerticalScrollbar enabled so that it activates when the text content is too big for actual size of the TextBox.

By default, Size of TextBox is fixed.

Now, when text content bigger/longer than the TextBox area is loaded into TextBox I need to obtain the actual Height of the TextBox for currently displayed text content (Height which should allow to display the whole content without need of use the scrollbar).

TextBox has WordWrap enabled.

How can we do that?

Clarify: you want to avoid the scrollbar by figuring out the height and then resizing it yourself? – DonBoitnott Oct 10 '17 at 15:42

Well scrollbar should be present, but I need in some cases manually force the size of text area – pitersmx Oct 10 '17 at 15:48
