Hi Nirmal,
I have tested on my local environment that as Visakh16 mentioned that you can use function like DATEADD(dd,DATEDIFF(dd,0,@StartDate),@StartTime) 
to get the date/time value based on the date and time parameter you have selectted.
There is also anoher method to add filter in the dataset but not in the query.Details information below for your reference；
Please change the datatype of the @sartdate and @enddate from text to date, if you don't specify an availbel value for these two parameters, you will get an calender picker to select the date.
I assumed the two time parameters will enter the value which format like:hh:mm or hh:mm:ssYou can conver the datetime field in the table to string and then compare with the conbine of the date and time field to filter the data
like below:
Filter add in the dataset like:
Expression:=FormatDateTime(Fields!DateTime.Value)           (String type)
Operator: Between
Value:
=Parameters!StartDate.Value &" "&Right(TimeValue(Parameters!StartTime.Value),8)
=Parameters!EndDate.Value &" "&Right(TimeValue(Parameters!EndTime.Value),8)
Preview the report:
If you still have any problem, please feel free to ask.
