转载：Asp.net Mvc的问题

转载自：http://www.cnblogs.com/chsword/archive/2008/10/06/aspnetmvc_qa.html

1. 用Html.Form生成表单：

<% using (Html.Form(c => c.Create(), FormMethod.Post, new{id="Create",@class="form" })) { %>
表单内容...
<%}%>

2. 为Helper添加事件：

<%= Html.DropDownList( "ddlStats", new { onchange, "changed();" } ) %>

3. DropDownList初始化：

You can implement a DropDown selector as something like as follows, where this example sets a options called "ScaleMode" on a "Camera" object.

This example is a little more complex because I needed to have 3 associated values:

• (Name) - Name to display to user.
• (Value) - Value to store in DB.
• (ConfigValue) - Value to write to config file.
  

Within the view:

<tr>

    <td>Scale Mode:</td>

    <td><%=Html.DropDownList(null, "ScaleMode", new SelectList(TheProjectName.Models.Camera.GetScaleModes(), "Value", "Name", ViewData.Model.ScaleMode))%></td>

</tr>

Within the Camera model:

public enum ScaleModeType : byte { none = 0, exactFit = 1, uniform = 2, fill = 3 };



public static IEnumerable GetScaleModes()

{

    return new[] {

                new { Name = "None", Value = (int)ScaleModeType.none, ConfigValue = "none" },

                new { Name = "Exactly fit", Value = (int)ScaleModeType.exactFit, ConfigValue = "exactfit" },

                new { Name = "Scale to fit", Value = (int)ScaleModeType.uniform, ConfigValue = "uniform" },

        new { Name = "Scale to fill", Value = (int)ScaleModeType.fill, ConfigValue = "fill" }

    };

And then your CameraController would have something like this:

public ActionResult Update(int id)

{

    try

    {

        viewData.Camera = db.Cameras.Single(a => a.Id == id);

        UpdateModel(viewData.Camera, Request.Form.AllKeys);

        db.SubmitChanges();



        return RedirectToAction("List");

    }

    catch (InvalidOperationException err)

    {

        viewData.ErrorMessage = err.Message;

        return View("Edit", viewData);

    }


4. RenderPartial的使用方法：

<% Html.RenderPartial("viewname");%>

5. 连接输出QueryString问题如/html/index?a=b&c=d

Html.ActionLink("xxx","Index","Home",new{a="b",c="d"},null)

6. Html.之后无智能感知：可能是没编译或建的不是Asp.net mvc的Page
7. Asp.net 不显示中文的解决方法：


    
将页面的culture属性改为中文
    
母板页中Content-Type改为：<meta http-equiv="Content-Type" c>




8. ReadFromRequest不存在的问题：
  Pv5之后已经去除,请用Request.Form/Param/Request.QueryString读取
