    Hi I want use this query and pass returned value as string to my view

    var model = db.LobTables.Where(p => p.Id.Equals(2)).Select(p => p.Clob);

    But I got this error
    System.InvalidOperationException: The model item passed into the dictionary is of type 'Telerik.OpenAccess.Query.Piece`1[System.String]', but this dictionary requires a model item of type 'System.String'

    my view is
    @model string
    @(Html.Kendo().EditorFor(m => m).Name("edit"))

    Hello Saeid,

    The reason is that you are binding the LINQ query to the UI directly, you should execute it first by calling SingleOrDefault() if you expect a single entity:

    var model = db.LobTables.Where(p => p.Id.Equals(2)).Select(p => p.Clob).SingleOrDefault();
