Hi Ravi,

You would need to make a programmatic text change for the range of the line like this:

editor.Document.ReplaceText(TextChangeTypes.Custom, editor.Document.CurrentSnapshot.Lines[3].TextRange, "newtext");

For a line background color there are a couple ways to do that:

1) Make a classification tagger and put it over the line's range.  The highlighting style associated with the classification type you assign should have a background.  Some of the Adornments samples show that sort of thing.

2) Make a line-based indicator.  This might be the best way to go.  See samples and docs on indicators.
