DateType: Date/Time with default value defined as expression:

=DateAdd("yyyy", -50, Now)



ActionOwnerDate_to

DateType: Date/Time with default value defined as expression:

=Now

I got error on this line:

reportViewer1.ServerReport.SetParameters(rptParameters);


Error:

reportViewer1.ProcessingMode = ProcessingMode.Remote;
var rptParameters = new List<ReportParameter>
{
new ReportParameter("ActionOwnerDate_from",
DateTime.Now.AddYears(-10).ToString(CultureInfo.InvariantCulture)),
new ReportParameter("ActionOwnerDate_to", DateTime.Now.ToString(CultureInfo.InvariantCulture))
