I am trying show a jQuery modal popup when error occurred in controller and display a same view where controller trying return.


How can we do that?

 HttpPost
 Function Traitement(model As TraitementViewModel) As ActionResult
     Dim exception As Exception = Nothing
    ...

     Catch ex As Exception
         Exception = ex
     End Try
     If (exception IsNot Nothing) Then
         Return PartialView("Errors", Statics.GetErreursForException(exception))
     End If
End Function

What I have tried:

partial View "Errors"

<pre>@ModelType IEnumerable(Of String)
<div>
 <hr />
        <h2>Les erreurs suivantes se sont produites</h2>
        <ul>
            @code
                For Each msg As String In Model
                @<li>
                    @msg
                </li>
                Next
            End Code
        </ul>
    </div>
