根据SSRS中的参数值调整日期值

Question

We have a SSRS report with Year , Start-Date, End-Date Fields ( Start-Date and End-Date are Date controls and Year is a Combo Value). I need the value of Start-Date and End-Date to be Restricted based on Year value.

For eg: If the Year value is 2016 , then the Start-Date and End-Date value should be between 01/01/2016 and 12/31/2016 .

How to do this in SSRS ?. Please Help

Answer 1

This can be accomplished with one drawback. Your date picker will no longer be a calendar it will be a drop down list with the dates.

Create a query that produces the list of dates you are looking for and add it to the report as a data set. Then in the properties of your Start-Date and End-Date report parameters click on the default values pane. Choose get values from query, select the appropriate dataset, value field, and label field.

After that when you run the report you will have a drop down with the list of dates your query returned. Just make sure you make your dates query dependant on the year report parameter.

I'd use the Year value to determine if StartDate and EndDate are dates between Year . Using a expression you can get the year from StartDate and compare it against Year value, based on that comparision you can set another parameter ( StartDateHidden ) which is hidden for users and populated depending on the comparision.

Expression for StartDateHidden .

=IIF(
  Paramaters!StartDate.Value.Year = Parameters!Year.Value,
  Paramaters!StartDate.Value,DateSerial(Parameters!Year.Value,1,1)
)

Note it populates StartDateHidden with the StartDate value if it is a date in Year value, otherwise it will set the first date of the Year value.

You can use any default value for cases when StartDate is not in the Year value.

Expression for EndDateHidden .

=IIF(
  Parameters!EndDate.Value.Year = Parameters!Year.Value,
  Parameters!EndDate.Value,DateSerial(Parameters!Year.Value,12,31)
)

Let me know if this helps.
