Hi Syman,
If you need text to display exactly as it is entered in a field, you will want to make use of the Rich Text widget.
First, you will need to enter the text in the rich text widget with the data source as your string attribute.
Then you will need to put the rich text widget in a custom content column of your datagrid 2 with the editable option set to never.
Then, your the text will appear in your datagrid 2 with the exact formatting that it is entered with.
Hope this helps!
