Hi Eric,

sorry for send this mail, but i need a few help.

im using the grid mvc contrib in my project and i find an scenarios that cant solve.

I put in a partialview the grid, that will draw for call of  ajax.beginform updating a div that render a html.renderpartial.
in ajax methos, call a action in controller that set an viewdata used from grid. but the grid in this scenarios dont work.

if i calling the action in controller via common form without ajax, works fine but i need update the infos at a div in my main page.

have you an suggestion?

I have an action page, which uses a renderpartial (ascx) where is the
grid.

The viewdata used from this grid is updated out either through form
ajax (ajax.beginform).

The error: the table is not generated by html.grid resulting in
empty table grid, the viewdata having a list of data.
If you call the ascx out of ajax, it works.

Works fine for me.

These are the steps I took to create a working example:

controller:

public class TestController : Controller {
   public ActionResult Index() {
      return View();
    }

    //This action will be called by Ajax
   public ActionResult PeopleGrid() {
       var people = new List<Person> {
                new Person() { Name = "Person 1", Id = 1 },
                new Person() { Name = "Person 2", Id = 2 },
                new Person() { Name = "Person 3", Id = 3 },
                new Person() { Name = "Person 4", Id = 4 },
            };

            ViewData["people"] = people;
           
            return View();
    }
}

Partial view - PeopleGrid.ascx

<%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl" %>

<%@ Import Namespace="MvcContrib.Samples.UI.Models"%>

<%@ Import Namespace="MvcContrib.UI.Grid"%>

<%= Html.Grid<Person>("people").Columns(column => {
        column.For(x => x.Id);
        column.For(x => x.Name);
}) %>

Main view - Index.aspx

<%@ Page Title="" Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage" %>
<asp:Content ID="Content1" ContentPlaceHolderID="MainContent" runat="server">
    <script type="text/javascript" src="/Scripts/MicrosoftAjax.js"></script>
    <script type="text/javascript" src="/Scripts/MicrosoftMvcAjax.js"></script>
   
   
    <% using (Ajax.BeginForm("PeopleGrid", new AjaxOptions { UpdateTargetId = "grid-placeholder" })) {%>
        <input type="submit" value="Load Grid" />
    <% } %>

    <div id="grid-placeholder"></div>
</asp:Content>

This works as expected.
