WPF textbox autogrow

Using WPF 3.5, I have a textbox with it's TextWrapping property set to
WrapWithOverflow.

When the number of lines increases in the textbox, how can I make the height
of the textbox grow to accommodate the all of the lines?

Also, I will need to go in the other direction and make the height shrink
when the number of lines reduces.

Thanks.

Hi Moondaddy,

In fact, the TextBox control in WPF has already provided the function of
auto expanding/shrinking with the content entered into it.

To get this feature, set the TextWrapping property of the TextBox to Wrap
or set the AcceptReturn property to true and then place the TextBox control
within a StackPanel (if you place the TextBox in a Grid, the auto
expanding/shrinking feature is not available).

In addition, you should not set the Height property of the TextBox to a
specific value. The value of the Height property of the TextBox displayed
in the Properties window should be "Auto".

If the value of the Height property has alreadly been set to a specific
value, e.g. 200 in your project, delete this value in the Properties window
and press Enter and "Auto" will be displayed in the property entry.

Please try my suggestion and let me know the result.

Sincerely,
Linda Liu
