ArcEngine打开属性表如何实现分页的功能？

 //创建空DataTable

            DataTable dataTable = CreateDataTabeByLayer(layer, tablename);

            //取得图层类型

            string shapeType = getShapeType(layer);

            //创建DataTable的行对象

            DataRow dataRow = null;



            ITable table = layer as ITable;

            ICursor cursor = table.Search(null, false);

            //取得ITable中的行信息

            IRow row = cursor.NextRow();

            int n = 0;

            while (row != null)

            {

                //新建DataTable的行对象

                dataRow = dataTable.NewRow();

                for (int i = 0; i < row.Fields.FieldCount; i++)

                {

                    //如果字段类型为esriFieldTypeGeometry,则根据图层类型设置字段

                    if (row.Fields.get_Field(i).Type == esriFieldType.esriFieldTypeGeometry)

                    {

                        dataRow[i] = shapeType;

                    }

                    //当图层类型为Anotation时,要素类中会有esriFieldTypeBlob类型的数据

                    //其存储的是标注内容,如此情况需将对应的字段值设置为Element

                    else if (row.Fields.get_Field(i).Type == esriFieldType.esriFieldTypeBlob)

                    {

                        dataRow[i] = "Element";

                    }

                    }

                }

                //添加DataRow到DataTable

                dataTable.Rows.Add(dataRow);

                dataRow = null;

                n++;



                //为保证效率,一次只装载2000条记录

                //if (n == 2000)

                //{

                //    row = null;

                //}

                //else

                //{
