C# 带有模板控件的ASPxGridView在IE 9.0&；中显示数据需要更多时间；10

我正在开发显示学生出勤情况的ASPxGridView。为此，我通过sqlqry筛选1600名学生中的60名学生。网格控件是在Design Environment中创建的，它有两列RollNo&Name和两列template列（即ASPxCombobox用于考勤状态，ASPxTextBox用于备注）。下面列出了设计窗口代码

<dx:ASPxGridView ID="dxgrd_StudentAttendance" runat="server" Theme="Glass" Width="800px"  AutoGenerateColumns="False" onprocesscolumnautofilter="dxgrd_StudentAttendance_ProcessColumnAutoFilter">

<Columns>

<dx:GridViewDataTextColumn FieldName="Name" VisibleIndex="2" Caption="Name of the Student" Width="300px">
</dx:GridViewDataTextColumn>

<dx:GridViewDataColumn FieldName="Attendance" VisibleIndex="3" Caption="Attendance Status" Width="100px">

                            <dx:ASPxComboBox ID="dxcb_AttStatus" runat="server" ValueType="System.String" Theme="Glass" Width ="100px">

问题是，在没有模板控件的情况下在aspxgridview中显示数据所花费的时间是可以接受的（比如1或2秒）。但是使用模板控件，在aspxgridview中显示数据所花费的时间大约是15到20秒（这是不可接受的）。提供的任何帮助或建议都将对我有很大帮助

谢谢你，你可以用这个

像这样

SqlDataSource sqlds_StudentAttendanceSection = new SqlDataSource();
SqlDataSource sqlds_StudentAttendanceDept = new SqlDataSource();

sqlds_StudentAttendanceSection.SelectCommand = String.Format("Select b.roll_no, b.Name from tbl_AcademicYear a, tbl_Student_Master b, tbl_Dept_Master c," +
