Hi,
I use Microsoft.ReportingServices.ReportViewerControl.WebForms to display reports in my ASP.Net MVC project.
After upgrade to 150.1427.0 version I started getting an exception when setting parameter values that are dates or int values.
Here is the stack trace:
Exception: System.NullReferenceException: Object reference not set to an instance of an object.
at Microsoft.ReportingServices.Common.DateTimeUtil.ParseDateToDefaultFormat(String strDateTime, CultureInfo formatProvider)
at Microsoft.Reporting.WebForms.ServerReport.SetParameters(IEnumerable`1 parameters)
According to the release notes there is a point: "Fixed a datetime parsing issue affecting certain locales."
https://learn.microsoft.com/en-us/sql/reporting-services/application-integration/release-notes-ssrs-application-integration?view=sql-server-ver15
So maybe something was broken there.
As I understand locale is taken from Thread.CurrentThread.CurrentCulture.Name and I have "en-US" value there, but it still doesn't work.
If I downgrade to version 150.1404.0 and the issue has gone.
Is there a way to make it work in 150.1427.0 version?

I am having the same issue and i could track down the cause.
This happens when setting a nullable date report parameter to null.
I assume the parameter parsing was changed and null values not taken into account.
It also breaks convention of null parameter handling in general because other parameters just print a missing value message instead of throwing an exception.
Is there a place where i can report this as a bug?
I have posted it here, but there is still not reply yet.

Hi @ZoeHui-MSFT ,
Ok, thanks. I give it a try on another forum, that you suggested.
Hi @Serhii K ,
The issue is related about develop, I'm not familiar with it.
As far as I known that there is a lot of differences between WebForms and MVC.
ReportViewer requires viewState and that's not in MVC.
We will need to go through some hacks to make it work. Generally speaking, it's not suggested to use the web form control in MVC.
So when we meet with some issue with ReportViewerControl and MVC, it's hard to define the issue.

Your comment was not helpful at all and makes little sense. The report tool is broken following an update. It has nothing to do with mvc and viewstate. I would suggest you you look into the issue instead of reading from a prepared script.
