Scrollbar for a Text Box

Hello All,

I have a text box and I have very less space to drag it. So, with the space available, I can see only 25 characters in the text box. But, the value in the text box would always be greater than 100 characters.

So, I thought of having a scrollbar for this text box. Theres is a property called "SCROLLBAR" for this textbox. But even when I set this property, I am not able to see the scrollbar.
