An expression tree may not contain a dynamic operation - mvc
asp.net-mvc, model
Solution
Expressions cannot be used with dynamic types. You will have to use strongly typed view models:
@model Tuple<IEnumerable<VM1>, IEnumerable<VM2>, IEnumerable<VM3>>
Problem
I have this in my code: ``` @model Tuple<IEnumerable<dynamic>, IEnumerable<dynamic>, IEnumerable<dynamic>> @(Html.Telerik().Grid(Model.Item3) .Name("Grid") .DataKeys(keys => keys.Add(c => c.Id)) ) ``` And I get the error: An expression tree may not contain a dynamic operation. Here is the controller code: ``` FirstClass firstC= new FirstClass (); IEnumerable<dynamic> first= firstC.All(); SecondClass secondC= new SecondClass (); IEnumerable<dynamic> second= secondC.All(); ThirdClass thirdc = new ThirdClass (); IEnumerable<dynamic> third= thirdc .All(); Tuple<IEnumerable<dynamic>, IEnumerable<dynamic>, IEnumerable<dynamic>> result = new Tuple<IEnumerable<dynamic>, IEnumerable<dynamic>, IEnumerable<dynamic>>(firstC, secondC, thirdc ); return View(result); ``` How to resolve this?
