devexpress.XtraGrid.GridControl 实现多选

转：http://www.cnblogs.com/jlfood/

添加一列,FieldName为 "check"，将ColumnEdit 设置为 复选框 样式。

  将要绑定的DataTable添加列 "check",Type 为 bool。

  绑定DataTable到GridControl。

  获取： string value = gridview.GetDataRow(i)["check"].toString();

         value == "true" ||  "" ("false")

 设置为多选

    gridView1 .OptionsSelection.MultiSelect = true;

   gridView1 .OptionsSelection.MultiSelectMode = DevExpress.XtraGrid.Views.Grid.GridMultiSelectMode.RowSelect;

测试的例子如下：

给gridcontrol添加数据

string strConn = "###";
            OracleConnection oconn = new OracleConnection(strConn);
            string strComm = "select CITY_NAME,DISTRICT_NAME from CC_COMPLAINT_POINT";
            OracleDataAdapter oda = new OracleDataAdapter(strComm, oconn);
            DataSet ds = new DataSet();
            try
            {
                oda.Fill(ds, "cx");
                ds.Tables["cx"].Columns.Add("check",System.Type.GetType("System.Boolean"));

                gridControl1.DataSource = ds.Tables["cx"];
                //Rel.DataSource = ds.Tables["cx"];
                //Rel.DisplayMember = "DISTRICT_NAME";
                //Rel.ValueMember = "CITY_NAME";

            }
            catch(Exception ex)
            {
                MessageBox.Show(ex.ToString());

            }
            finally
            {
                oconn.Close();

            }

string strConn = "###";            OracleConnection oconn = new OracleConnection(strConn);            string strComm = "select CITY_NAME,DISTRICT_NAME from CC_COMPLAINT_POINT";            OracleDataAdapter oda = new OracleDataAdapter(strComm, oconn);            DataSet ds = new DataSet();            try            {                oda.Fill(ds, "cx");                ds.Tables["cx"].Columns.Add("check",System.Type.GetType("System.Boolean"));                gridControl1.DataSource = ds.Tables["cx"];                //Rel.DataSource = ds.Tables["cx"];                //Rel.DisplayMember = "DISTRICT_NAME";                //Rel.ValueMember = "CITY_NAME";                            }            catch(Exception ex)            {                MessageBox.Show(ex.ToString());            }            finally            {                oconn.Close();             }

点击测试check按钮响应如下事件（获取被check的数据）

private void buttonX3_Click(object sender, EventArgs e)
        {
            string value="";
            string strSelected="";
            for (int i = 0; i < gridView1.RowCount; i++)
            {
                value = gridView1.GetDataRow(i)["check"].ToString();
                if (value == "True")
                {
                    strSelected += gridView1.GetRowCellValue(i, "DISTRICT_NAME");

                }
            }
            MessageBox.Show(strSelected);
        }

private void buttonX3_Click(object sender, EventArgs e)        {            string value="";            string strSelected="";            for (int i = 0; i < gridView1.RowCount; i++)            {                value = gridView1.GetDataRow(i)["check"].ToString();                if (value == "True")                {                    strSelected += gridView1.GetRowCellValue(i, "DISTRICT_NAME");                 }            }            MessageBox.Show(strSelected);        }

运行结果如下：
