How to Change Date Format of Report Parameters of DateTime Type in report Parameter Panel?

[Prabesh]

Hi Telerik Team,

I'm using Telerik Reporting in an ASP.NET MVC application. I have a generic helper method to configure the Telerik Report Viewer using a UriReportSource. Here's the function:

public static class ReportExtension
{
    public static IReportViewerBuilder GetReportViewerConfig(this HtmlHelper htmlHelper, string reportId, string reportSource, Dictionary<string, string> reportParams)
    {
        var uriReportSource = new UriReportSource
        {
            Uri = reportSource
        };

        foreach (var param in reportParams)
        {
            uriReportSource.Parameters.Add(param.Key, param.Value);
        }

        return htmlHelper.TelerikReporting().ReportViewer()
            .Id(reportId)
            .ReportServer(new ReportServer()
            {
                Url = ReadConfigData.REPORT_SERVER_URL,
                Username = ReadConfigData.REPORT_SERVER_USERNAME,
                Password = ReadConfigData.REPORT_SERVER_PASSWORD
            })
            .ReportSource(uriReportSource)
            .ViewMode(ViewMode.Interactive)
            .ScaleMode(ScaleMode.FitPageWidth)
            .PersistSession(false)
            .SendEmail(new SendEmail { Enabled = true })
            .Parameters(new Parameters
            {
                Editors = new Editors
                {
                    MultiSelect = EditorTypes.ComboBox,
                    SingleSelect = EditorTypes.ComboBox
                }
            })
            .EnableAccessibility(false);
    }
}

The Problem:
I'm using DateTime parameters (e.g., dateFrom, dateUntil) in my reports, and they appear in the report 
parameter panel with the format MM/dd/yyyy. I want to show these dates as dd/MM/yyyy.
 


My Questions:
1. Is it possible to customize the display format (e.g., dd/MM/yyyy) of DateTime parameters in the parameter input panel?
2. If not, is there any workaround — such as setting culture explicitly for the viewer?
