                    </td>
                </tr>
                <tr>
                    <td>

                                ShowFooter="True"
                                ShowHeaderFilterButton="true"
                                ShowGroupFooter="VisibleAlways"
                                ShowPreview="True"
                                ShowVerticalScrollBar="True"
                                VerticalScrollableHeight="500" />
                            <SettingsBehavior AllowDragDrop="true" ColumnResizeMode="Control" AllowFocusedRow="True" AllowSort="true" />
                            <Columns>
                                <dx:GridViewDataTextColumn Caption="账号" FieldName="UsrID" Name="ColUsrID" VisibleIndex="0" Width="120px">

                                </dx:GridViewDataTextColumn>
                            </Columns>
                        </dx:ASPxGridView>
                    </td>
                    <td>
                        <dx:ASPxGridView ID="ASPxGridView2" runat="server" AutoGenerateColumns="False" KeyFieldName="ItemNO" Width="100%">
                            <Settings
                                GridLines="Both"
                                ShowGroupPanel="False"
                                ShowFooter="True"
                                ShowHeaderFilterButton="true"
                                ShowGroupFooter="VisibleAlways"
                                ShowPreview="True"
                                ShowVerticalScrollBar="True"
                                VerticalScrollableHeight="500" />
                            <SettingsBehavior AllowDragDrop="true" ColumnResizeMode="Control" AllowFocusedRow="True" AllowSort="true" />

                            <Columns>
                                <%--;....................................................................;--%> 
                                <dx:GridViewCommandColumn ShowSelectCheckbox="True" VisibleIndex="0" Caption="选择" Name="ColChk" Width="36px">
                                    <HeaderTemplate>
                                        <dx:ASPxCheckBox ID="DchkAll" runat="server"  
                                            ClientSideEvents-CheckedChanged="function(s,e){ASPxGridView2.SelectAllRowsOnPage(s.GetChecked());}">
                                        </dx:ASPxCheckBox>
                                    </HeaderTemplate>

                                </dx:GridViewDataTextColumn> 
                            </Columns>

                        </dx:ASPxGridView>
                    </td>
                </tr>
            </table>

二、Cs 后端代码

   /// <summary>
        /// 获取 ItemNO 列的内容
        /// </summary>
        /// <returns></returns>
        protected string GetDelID()
        {
            string delId = "";
            //获取选中的记录Id                   
            List<object> lSelectValues = ASPxGridView2.GetSelectedFieldValues("ItemNO");
            if (lSelectValues.Count==0)
            { return ""; };
            for (int i = 0; i < lSelectValues.Count; i++)
            {
                delId += lSelectValues[i] + ",";
            }
            delId = delId.Substring(0, delId.LastIndexOf(','));
            return delId;
        }
