## 2.JQuery EasyUI弹出对话框解决Asp.net服务器控件无法执行后台代码的方法 ##

var dlg = $('#dd').dialog({
                    title: '导入excel,请选择..',
                    width: 400,
                    height: 150,
                    closed: true,
                    cache: false,
                    modal: true,
                    //href: '../UpLoad.aspx'
                });
                //在点击按钮打开Dialog时，将div append到form里，使按钮生效。 
                dlg.parent().appendTo(jQuery("#form1"));
                
                //导入excel
                $('#A2').click(function () {
                    dlg.dialog('open');
                   
                    //console.info(dlg.parent());
                });

解决方法：在点击按钮打开Dialog时，将div append到form里，使按钮生效。

将弹出div append到属于form里的div，那么服务器端控件就可以正常执行

## 3. 三张表的连接查询现在到datagrid里 ##

3.1 存储过程：

------------------------------------
    --用途：查询PKE_DeviceContent与PKE_Franchiser还有PKE_DeviceNumber的3张表的连接查询
    --项目名称：
    --说明：查询PKE_DeviceContent多余的数据
    --时间：2013-09-08 20:11:23
    ------------------------------------
    ALTER PROCEDURE [dbo].[PKE_DeviceContent_Select]
    @GetOne nvarchar(50)
     AS 
        select a.ConID,a.DeviceNumber,a.longitude,a.latitude,a.AlarmStatus,a.uploadtime,
    a.vehicleState,a.PositionStatus,a.BeginTime,a.EndTime,a.Adderss,b.FranchiserName,c.Remark from 
     PKE_DeviceNumber b
    inner join dbo.PKE_Franchiser c
    on 
     c.FranchiserName=b.FranchiserName
     inner join PKE_DeviceContent a
     on 
     a.DeviceNumber=b.DeviceNumber
     where a.DeviceNumber like '%'+@GetOne+'%'

4.日期组合框DateBox设置readonly的解决方法。

//继承自combo，使用combo的editable属性设置readonly.
                $("#BeginTime").datebox({ editable: false });
                //$("#Content input[name='BeginTime']").attr('readonly', 'readonly');
                $("#EndTime").datebox({ editable: false });
                //$("#Content input[name='EndTime']").attr('readonly', 'readonly');
