Wdatepicker start date cannot be greater than end date, end time cannot be less than start time

<input class= "Input_calendar inputcss" id= "StartDate" runat= "Server" type= "text"  
Onfocus= "Wdatepicker ({maxdate: ' #F {$dp. $D (\ 'endDate\ ') | | \ ' 2120-10-01\ '} ') "  style=" height:30px; width:153px; />

Note: If more than one function is required for control in Wdatepicker, each function is separated by commas. such as: onclick= "Wdatepicker ({maxdate: ' #F {$dp. $D (\ ' endtimevalue\ ') | | \ ' 2120-10-01\ '} ', datefmt: ' Yyyy-mm-dd '}) "

<input class= "Input_calendar inputcss" id= "endDate" runat= "Server" type= "text" onfocus= "Wdatepicker ({mindate : ' #F {$dp. $D (\ 'startdate\ ')} ', MaxDate: ' 2120-10-01 '}) "  style=" height:30px; width:153px; " />



The start date cannot be greater than the end date, the most error-prone place is the yellow background section, and the control ID forgets to set. MaxDate is the maximum date range.
