I used below code but its not working not equal to 0.65 condition .but its working equal to 0.65 condition.

Style heading4 = doc.Styles[StyleIdentifier.Heading4];
heading4.ParagraphFormat.FirstLineIndent = ConvertUtil.InchToPoint(-0.6);
heading4.ParagraphFormat.LeftIndent = -heading4.ParagraphFormat.FirstLineIndent;
heading4.ParagraphFormat.KeepWithNext = false;
heading4.ParagraphFormat.KeepTogether = false;
heading4.ParagraphFormat.TabStops.Add(ConvertUtil.InchToPoint(0.65), TabAlignment.Left, TabLeader.None);
heading4.ParagraphFormat.Style.IsQuickStyle = true;

@Princeshivananjappa Looks like you need to clear/remove tab stop at the specified position. You can achieve this using TabStopCollection.RemoveByIndex or TabStopCollection.RemoveByPosition.

Kindly help me I used your give above property but its not working.
