asp.net mvc parameter from page to a partial view

问题

I'm with a problem, I have a ajax link that pass a parameter, but, the page that it opens does not need that parameter. The page only load 2 partial views, one of those need that parameter passed to the page to load the data correctly, and the other just need to load a form, so, don't need that parameter. How can i acheive this?

回答1:

In order to do what you want, you will need to add the id to the ViewData construct.

var sysfunctions= UnisegurancaService.FunctionsRepository.All();
ViewData["NeededID"] = id
return View(sysfunctions);

then in your view where you render the partial

<%= Html.RenderPartial("GridFunction", (int)ViewData["NeededID"]) %>

Cast as required of course.

Whatever gets pushed in as the second param becomes the .Model in the partial. I would suggest also strongly typing your partials.

Try this:

<% Html.RenderPartial("GridFunction", new ViewDataDictionary {{"Id", ViewData["Id"]}}); %>

UPDATED:

And add this in your controller action:

ViewData["Id"] = Id;

UPDATED:

And in your GridFunction partial View you can access Id as:

<%= ViewData["Id"] %>

//Controller

  public ActionResult EditFunctions(int id)
    {

        var sysfunctions= UnisegurancaService.FunctionsRepository.All();
        return View(sysfunctions);
    }
    // This is the controller (it does no need the parameter "ID")

//This is the view "EditFunctions"

<div id="formFunction">
<% Html.RenderPartial("FormFunction"); %>
</div>


<div id="gridFunction">
<% Html.RenderPartial("GridFunction"); %> // The grid needs the ID to work correctly but its in the parent page not in the partial call....and the call is an ajax call
</div>

If some dependency of the page needs the parameter, then the page needs to know enough to pass the data in, so the page should be able to provide the data. Or, more simply, just add the parameter to the Page's viewdata and be done with it.
