Hi svibuk,
Check the actionName and the routeValues.
As per your code @Url.Action requires two parameter string and object Action(String, Object)
actionName - The name of the action method.
Type: System.String
routeValues - An object that contains the parameters for a route. The parameters are retrieved through reflection by examining the properties of the object. The object is typically created by using object initializer syntax.
Type: System.String
Ensure you are passing valid parameter.
