DataGridView中一列一列的绑定

 

1.   DataGridView中一列一列的绑定（列名存在集合arrList中，数据存在DataTable）

解释：集合(arrList)中存SQL语句SELECT中的”名字”转换成DataTable的“列名”

//通过集合中的名字创建列名

protected DataTable CreateTable(ArrayList arrList, DataReader reader)

                            // reader可以从ExecuteReader获得

        {

// DataTable的名字

            DataTable dt = new DataTable("table");

           

//给DataTable定列名

            for (int i = 0; i < arrList.Count; i++)

            {

                DataColumn dtColumn = new DataColumn();

                dtColumn.ColumnName = (string)arrList[i];

                dt.Columns.Add(dtColumn);

            }

 

            //往DataTable里加行

            DataRow dtRow;

            while (reader.Read())

            {

                dtRow = dt.NewRow();

                for (int i = 0; i < arrList.Count; i++)

                {

                    try

                    {

                        dtRow[(string)arrList[i]] = reader.GetValue(i).ToString();

                    }

                    catch

                    {

                        dtRow[(string)arrList[i]] = System.DBNull.Value;

                    }

                }

                dt.Rows.Add(dtRow);

            }

            return dt;

        }

 

DataTable m_listViewInfo = CreateTable（集合名，DataReader名）；

 

//将DataTable绑定到DataView中

DataView dvListViewInfo = new DataView(m_listViewInfo);

dataGridView1.Columns.Clear();

//取消dataGridView1按默认方式显示

dataGridView1.AutoGenerateColumns = false;

//绑定DataView到dataGridView上

dataGridView1.DataSource = dvListViewInfo;

 

DataGridViewTextBoxColumn dtcTimeStamp = new DataGridViewTextBoxColumn();

dtcTimeStamp.DataPropertyName = "TIMESTAMP";//SQL语句得到的列名，可从集合中获得

dtcTimeStamp.HeaderText = "日期";//列头显示的汉字

dtcTimeStamp.Width = 110;

dataGridView1.Columns.Add(dtcTimeStamp);//最后一定要添加进去
