Hello

 I have a problem with a ascx view control and the view data. If work like this:

 public void AjaxTr<T>(string id, Expression<Action<T>> detailAction,
            Expression<Action<T>> editAction) where T : Controller, new()
        {
            string viewName = ActionUtils.GetViewName<T>(detailAction);
            htmlHelper.RenderPartial(viewName);
        }

There is no more ViewData in the PartialView (ascx-File). The ViewData in the Controller T(detailAction) is existent and correct. But it is empty in the PartialView (there is only the ViewData of the aspx Page where I call the renderPartial Method).

Can you help me with this?

 make sure the ascx file inherits from ViewUserControl.

Ok, maybe I was not precise enough.

I want to dynamically render an action via renderpartial. But renderpartial does not support to render actions as I understand.

I have this function:

public void AjaxDiv<T>(string id, string title, Expression<Action<T>> detailAction,
            Expression<Action<T>> editAction, bool isOpen) where T : Controller, new()
        {

And from the Action<T> editAction I want to get the viewdata or better, I want to call the editAction like when I am just opening it directly via link.

And this function is in a separated class library.

In the view it is like this:

<% AjaxBlocks.AjaxDiv<SupplierProductDataController>("supplierData", "Supplier data",
        c => c.List(product.Id), false); %>

The target is, that the first time I load the view/controller it renders everything. And then I have an AJAX div which updated via JQuery. Everything with the JQuery works perfect. It is just a problem to load the usercontrol with the first page request directly (via ajax the page load is not that smooth cause every block appears another time).

One problem is, that I want to render this partial view but it is from another controller. With this renderview I can only render partialviews (ascx) from shared folders or from the correct controller which contains the main view. Maybe the old renderaction would have solved my problem.

I want to call the editAction like when I am just opening it directly via link.

You want RenderAction, not RenderPartial

 Yes, but there is not more renderaction in Preview 5. What is the solution?

What are you talking about? Of course there is!

Look in Microsoft.Web.Mvc.dll?

 Ok, it works like that. Thank you very much and sorry for the "blindness" (only used the system.web.mvc and visual studio did not recommend any using when I right clicked my mouse).

Now the first request is rendered directly with renderaction and then the block can be edited via ajax.
