I am just starting on MVC so this should be an easy question to answer. I am using MVC 2 for ASP.Net. I have a drop down list which when changes should cause the grid to change as well. I have found a way to catch the change selection event and refresh 开发者_开发技巧the whole form using the code below. The $('#TheForm').submit(); command causes the Index method of the Controller to run, and resets everything back as before. What I want of course is for this method to pick up the new value of the dropdownlist, extract and display the new data in the View accordingly. Is this how I should do it, or should I do more on the client side instead?
$(function () { $("#StatusId").change(function () { $('#TheForm').submit(); }); });
<p>
<% using (Html.BeginForm("Index", "Home", FormMethod.Post, new { id = "TheForm" })){%>
<%: Html.DropDownList("StatusId", (SelectList) ViewData["Status"]) %>
<%}%>
</p>
<p>
<% if (Request.IsAuthenticated) { %>
<%: Html.ActionLink("Add new item", "Add") %>
<% } %>
</p>
<table>
<tr>
<th>
Title
</th>
<th>
Date
</th>
<th>
Status
</th>
</tr>
<% foreach (var item in Model) { %>
<tr>
<td>
<%: Html.ActionLink(item.Title, "Details", new { id = item.ItemCode }) %>
</td>
<td>
<%: String.Format("{0:g}", item.DateCreated) %>
</td>
<td>
<%: item.Status %>
</td>
</tr>
<% } %>
</table>
<p>
<%: Html.Label("Page: ") %>
<% for (int i = 1; i < Convert.ToInt32(ViewData["NumberOfPages"]); i++)
{ %>
<%: Html.ActionLink(i.ToString(), "Index", new { page = i })%>
<% } %>
</p>
The Index action needs a parameter StatusId.
It has to filter the list of items by StatusId. If this does not work please post the code of the action.
