gridcontrol中添加checkbox复选框

 

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：
