Sometimes I need to be able to allow the users to choose not only the date but the time as well when displaying DateTime report parameters in my reports. There is no out-of-the-box functionality to achieve this and I am forced to implement custom parameter editors -  Creating and Using Custom Parameter Editors in HTML5 ReportViewer - Telerik Reporting.

I should be able to set whether a DatePicker or DateTimePicker widget should be used for DateTime parameters from the report viewer's initialization options, such as how I can change the editor for single/multi-value parameters in the HTML5 report viewers - HTML5 Report Viewer Options Overview - Telerik Reporting.
