Requirement as per client in all reports that on page load report will be loading with default values for filter and after that user can select any values in any filter criteria and click on button in that case report needs to be updated on the basis of filter criteria. Currently i am using Reportviwer with html helper Please help me your earliest i have to give this Demo to client on Thursday evening.

   var typeReportSource = new TypeReportSource() { TypeName = "ClientTrackingReport" };
    typeReportSource.Parameters.Add("X", Model.X);
    typeReportSource.Parameters.Add("Y", Model.Y);
    typeReportSource.Parameters.Add("Z", Model.Z);
    typeReportSource.Parameters.Add("A", Model.A);

Hi Praveen,

You can find general information how the HTML5 Report Viewer and Reporting REST service work in the following forum thread: 400 Bad Request for /api/reports/clients/{client_id}/parameters.

In your scenario you use the assembly qualified name of the report, which has to be in the format <namespace>.<report_name>, <assembly_name>. Then to avoid the persisting of the report between requests you need to set the viewer's persistSession option to false. The parameters passed from the report source object will be mapped to the report's ReportParameters collection by key.

Parameters which Visible property is set to false would not be listed in the viewer's parameters area. Details how to update their values from outside the viewer are available in the How To: Pass values to report parameters help article.

In future, if it is an emergency please use our support ticketing system, which assigns response time based on your support subscription.
