I am trying hard to get the scrollbar in the textbox to display logs with time stamps but I need to make it noneditable and able to scroll history logs. Please help me out with it.
Thank you.

If you mean you want the text fields to not be editable in the app itself, you could use labels instead, which can be found under User Interface -> Label

Right now, I assume you are using TextBox, right? These can indeed be modified by the user, whereas labels remain static unless the code changes them.

For scrolling, you could use the ScrollArangement layouts found under the Layout tab.

As a side note, I'm not sure if right now it is possible to add more Labels via script. It might be that the only solution right now is to create a fixed number of Labels, and fill them with text using scripts. Maybe someone else could clarify on this.

But I wanted to show logs. Dynamically around 50 lines, each line one under another with scroll. If I use labels, Using 50 labels in a scrollbar layout seems to be a nonfeasible solution. 

I just wanted a display unit which is verticle scrollable when the data goes out of view in the display

Something like this:

Place a vertical scrolling arrangement and fix the height
Inside that place a label and set height to automatic
The label will scroll once the length(height) of your log exceeds the height of the vertical scrolling arrangement

You don't say where your log data is coming from or in what format, I just created a csv from text blocks to make a list

A List Picker is scrollable.

Load its Elements from the list of log entries.

Sometimes people ask for the wrong thing,
not knowing of something better ...
