Conditional Expression for TextField

[p.meher09]

I am adding conditional style for textField, I want to display all the negative number in a different color, but the conditional style are applying to entire row instead of the current field. Please suggest how to enable it to a particular filed only?

I can think of two possible places to check.

1. a rectangle element would have been inserted with the conditional style behind the textfields
2. all the textfields would have been applied with the conditional style

sample code below

My problem is I am applying same style to all column, let's say "style1" to three column, and in column 3 one value is -ve, so the conditional style is applying to entire row when value is negative. Do we need to apply different style name for each column?
Please advice.
