I'm using Telerik reports in an asp.net MVC project.

A report I'm trying to generate is failing before it gets started, in the [HttpPost] ActionResult in the Controller; I reckon because "if 
(ModelState.IsValid)" is returning false.

I didn't know what IsValid was; on investigation, I see that it is defined in System.Web.Mvc.ModelStateDictionary

So what are the causes of a ModelStateDictionary being invalid? What should I examine or verify?

Hello Clay,

The provided information is not enough to determine what causes the exception. Please check if you have covered the steps from the Telerik Reporting in MVC? Sure. It takes 8 quick steps. blog. You can compare your code with the examples provided in Using Telerik Web ReportViewer in ASP.NET MVC application.

If you need further help, please share the full stack trace, your controller code and the aspx page markup.

All the best,
