DevExpress.Data.Filtering.Helpers.LikeData.CreateContainsPattern已过时

   protected override string OnCreateLookupDisplayFilter(string text, string displayMember)
        {
            List<CriteriaOperator> subStringOperators = new List<CriteriaOperator>();
            foreach (string sString in text.Split(' '))
            {
                string exp = DevExpress.Data.Filtering.Helpers.LikeData.CreateContainsPattern(sString);
                List<CriteriaOperator> columnsOperators = new List<CriteriaOperator>();
                foreach (GridColumn col in Columns)
                {
                    if (col.Visible && col.ColumnType == typeof(string))
                        columnsOperators.Add(new BinaryOperator(col.FieldName, exp,BinaryOperatorType.Like));
                }
                subStringOperators.Add(new GroupOperator(GroupOperatorType.Or, columnsOperators));
            }
            return new GroupOperator(GroupOperatorType.And, subStringOperators).ToString();
        }

修改成以下代码

      protected override string OnCreateLookupDisplayFilter(string text, string displayMember)
        {
            List<CriteriaOperator> subStringOperators = new List<CriteriaOperator>();
            foreach (string sString in text.Split(' '))
            {
                List<CriteriaOperator> columnsOperators = new List<CriteriaOperator>();
                foreach (GridColumn col in Columns)
                {
                    if (col.Visible && col.ColumnType == typeof(string))
                        columnsOperators.Add(new FunctionOperator(FunctionOperatorType.Contains, new OperandProperty(col.FieldName), sString));
                }
                subStringOperators.Add(new GroupOperator(GroupOperatorType.Or, columnsOperators));
            }
            return new GroupOperator(GroupOperatorType.And, subStringOperators).ToString();
        }
