Is there a conflict between RouteValueDictionary and htmlAttributes?

Question

I use RouteValueDictionary to pass RouteValues ​​to ActionLink:

If I code:

<%:Html.ActionLink(SharedResources.Shared_Pagination_First, Model.ActionToExecute, Model.ControllerToExecute, Model.FirstRouteValues, null)%> 

Link Result: Ok:

 SearchArticles?refSearch=2&exact=False&manufacturerId=5&modelId=3485&engineId=-1&vehicleTypeId=5313&familyId=100032&page=0 

But if I code:

 <%: Html.ActionLink(SharedResources.Shared_Pagination_First, Model.ActionToExecute, Model.ControllerToExecute, Model.FirstRouteValues, new { @title = string.Format(SharedResources.Shared_Pagination_LinkTitle, 0) })%> 

Link Result:

 SearchArticles?Count=10&Keys=System.Collections.Generic.Dictionary%602%2BKeyCollection%5BSystem.String%2CSystem.Object%5D&Values=System.Collections.Generic.Dictionary%602%2BValueCollection%5BSystem.String%2CSystem.Object%5D 

What is the problem? The only difference is that in the last I use htmlAttributes

Answer 1

You are using the wrong overload of the ActionLink helper. There is no overload that accepts routeValues as RouteValueDictionary and htmlAttributes as an anonymous object. Therefore, if Model.FirstRouteValues is RouteValueDictionary , then the last argument should also be RouteValueDictionary or a simple IDictionary<string,object> , and not an anonymous object. Similar:

 <%= Html.ActionLink( SharedResources.Shared_Pagination_First, Model.ActionToExecute, Model.ControllerToExecute, Model.FirstRouteValues, new RouteValueDictionary( new { title = string.Format(SharedResources.Shared_Pagination_LinkTitle, 0) } ) ) %> 

or

 <%=Html.ActionLink( SharedResources.Shared_Pagination_First, Model.ActionToExecute, Model.ControllerToExecute, Model.FirstRouteValues, new Dictionary<string, object> { { "title", somevalue } })%> 

Answer 2

There is no overload that matches your parameters, you must either use object for the route and html, or RouteValueDictinary and IDictionary<string,object> .

Same:

 Html.ActionLink(SharedResources.Shared_Pagination_First, Model.ActionToExecute, Model.ControllerToExecute, Model.FirstRouteValues, new Dictionary<string.object> { { "title", somevalue } })
