一、Dev单元格

二、获取表格数据

 int selectRow = gridView1.GetSelectedRows()[0];
 string id = this.gridView1.GetRowCellValue(selectRow, "id").ToString();

　　

            string colValue = this.gridView1.GetRowCellValue(this.gridView1.FocusedRowHandle, this.gridView1.Columns["qty"]).ToString();
            var s = gridView1.GetDataRow(e.RowHandle)["列名"].ToString();  //当前单元格所在行的数据
　　　　　　　　注意 e.value 获取当前编辑的值，上面对编辑单元格无效，只可以触发 GridView1_CellValueChanging 事件 

　　

'设置单元格中的值
GridView.SetRowCellValue(GridView.FocusedRowHandle, GridView.Columns("列名"),"要设置的值"）
 
'得到单元格中的值
Me.GridView_Analysis.GetRowCellValue(GridView.FocusedRowHandle, "列名")
 
'数据表中当前单元格的值
DataSet.Tables(0).Rows(GridView.FocusedRowHandle).Item("列名")

一、Dev单元格只允许输入数字　

        private void GridView1_CellValueChanging(object sender, DevExpress.XtraGrid.Views.Base.CellValueChangedEventArgs e)
        {
            if (Convert.ToInt32(this.gridView1.GetDataRow(e.RowHandle)["qty"]) < e.Value.ToInt())
            {
                this.gridView1.SetRowCellValue(e.RowHandle, "pick_qty", Convert.ToInt32(this.gridView1.GetDataRow(e.RowHandle)["qty"]));
                this.gridView1.SetRowCellValue(e.RowHandle, "qty-pick_qty", 0);
            }
            else if (e.Value.ToString() == "")
            {
                this.gridView1.SetRowCellValue(e.RowHandle, "pick_qty", 0);
                this.gridView1.SetRowCellValue(e.RowHandle, "qty-pick_qty", Convert.ToInt32(this.gridView1.GetDataRow(e.RowHandle)["qty"]));
            }
            else
            {
                this.gridView1.SetRowCellValue(e.RowHandle, "qty-pick_qty", Convert.ToInt32(this.gridView1.GetDataRow(e.RowHandle)["qty"]) - e.Value.ToInt());
            }
        }

        private void GridData_EditorKeyPress(object sender, KeyPressEventArgs e)
        {
            GridControl grid = sender as GridControl;
            gridView1_KeyPress(grid.FocusedView, e);
        }
        private void gridView1_KeyPress(object sender, KeyPressEventArgs e)
        {
            if (e.KeyChar == '' || e.KeyChar == '
')
            {
                e.Handled = false;
                return;
            }
            GridView view = sender as GridView;
            string s = "0123456789";
            if (view.FocusedColumn.FieldName == "pick_qty" && s.LastIndexOf(e.KeyChar) >= 0)
            {
                e.Handled = false;

            }
            else
                e.Handled = true;
        }
