ModelState.AddModelError not showing any message

Question

I am using telerik mvc grid. In my table I have unique key defined for a field. And in controller I am catching the error using try ... catch inside DbUpdateException. in catch block I want to handle the error and show error messsage in view. So using following line, ``` ModelState.AddModelError("PROGRAM_ID", "Access for this program already exists."); return View(); ``` But this is not showing error message. Any idea why?

Accepted Answer

Make sure that you have a corresponding `ValidationMessage` in your view with the same key:

```
@Html.ValidationMessage("PROGRAM_ID")
```
