c# DataGridView绑定DataTable数据源并指定对应

//指定对应关系的关键在于两点：

1、dgv的 AutoGenerateColumns = false;

2、DataGridView新加入列的fieldNameColumn.DataPropertyName = "field-name";//这要和DataTable的属性名一样




 /// <summary>
        /// 设置GridView显示样式
        /// </summary>
        private  void  SetSettingGridViewDisplay()
        {
            //throw new NotImplementedException();
            this .GV_ColumnInfo.AutoSizeRowsMode = DataGridViewAutoSizeRowsMode.AllCellsExceptHeaders;
            this .GV_ColumnInfo.ColumnHeadersBorderStyle = DataGridViewHeaderBorderStyle.Sunken;
            this .GV_ColumnInfo.CellBorderStyle = DataGridViewCellBorderStyle.Single;
            this .GV_ColumnInfo.RowHeadersVisible =  false ;
            this .GV_ColumnInfo.AutoGenerateColumns =  false ;
            this .GV_ColumnInfo.AllowUserToAddRows =  false ;
            this .GV_ColumnInfo.AllowUserToResizeRows =  false ;
        }




显示的时候指定一下：
如下：

 bindingSource.DataSource = itemAttributeDataTable;
                this .GV_ColumnInfo.DataSource = bindingSource;

                DataGridViewColumn fieldNameColumn =  new  DataGridViewTextBoxColumn();
                fieldNameColumn.HeaderText =  "field_name" ;
                fieldNameColumn.DataPropertyName =  "field-name" ; //这个很重要，对应的是你数据源的字段名
                this .GV_ColumnInfo.Columns.Add(fieldNameColumn);

                DataGridViewColumn idColumn =  new  DataGridViewTextBoxColumn();
                idColumn.HeaderText =  "id" ;
                idColumn.DataPropertyName =  "id" ;
                this .GV_ColumnInfo.Columns.Add(idColumn);

                DataGridViewColumn identifierColumn =  new  DataGridViewTextBoxColumn();
                identifierColumn.HeaderText =  "identifier" ;
                identifierColumn.DataPropertyName =  "identifier" ;
                this .GV_ColumnInfo.Columns.Add(identifierColumn);

                //下拉列表绑定时候，DataPropertyName和ValueMember做对比，
                DataGridViewComboBoxColumn typeColumn =  new  DataGridViewComboBoxColumn();
                typeColumn.DataSource = GetComBoxDataSource();
                typeColumn.Width = 200;
                typeColumn.DataPropertyName =  "type" ;
                typeColumn.DisplayMember =  "Text" ;
                typeColumn.ValueMember =  "Values" ;
                typeColumn.HeaderText =  "type" ;
                //typeColumn = ComboBoxStyle.DropDownList;
                this .GV_ColumnInfo.Columns.Add(typeColumn);

                DataGridViewColumn lengthColumn =  new  DataGridViewTextBoxColumn();
                lengthColumn.HeaderText =  "length" ;
                lengthColumn.DataPropertyName =  "length" ;
                this .GV_ColumnInfo.Columns.Add(lengthColumn);

楼主这个问题有几种方法可以解决，我所知道的就有三种，
1，在源头过滤，即使用ＳＱＬ语句时就过滤掉。
2，把ＤＡＴＡＧＲＩＤ的字段的visble设为false.
3，指定ＤＡＴＡＧＲＩＤ的列所对应的ＤＡＴＡＴＡＢＬＥ的列。
可能还有其它方法，楼主还是多试试吧。
