Question

if (colFilter.Contains(" IN ") == true )
                {
                    var temp1 = colFilter.Trim().Split(new string[] { "IN" }, StringSplitOptions.None);

                    colName = GetStringBetweenChars(temp1[0], '[', ']');

                    var filterValsList = temp1[1].Split(',');

                    newColFilter += string.Format("({0} != null && (", colName);

                    string orOperator = "";

                    foreach (var filterVal in filterValsList)
                    {
                        double tempNum = 0;
                        if (Double.TryParse(filterVal, out tempNum))
                            newColFilter += string.Format("{0} {1} = {2}", orOperator, colName, filterVal.Trim());
                        else
                            newColFilter += string.Format("{0} {1}.Contains({2})", orOperator, colName, filterVal.Trim());

                        orOperator = " OR ";
                    }

                    newColFilter += "))";
