如何在MVC3中为以下Razor代码设置页面加载时"Amount"文本框？

        <tr>
            <th>
                <div class="editor-label">
                    @Html.LabelFor(model => model.Amount)
                </div>                            
            </th>
             <td>
                 <div class="editor-field">
                    @Html.EditorFor(model => model.Amount)
                    @Html.ValidationMessageFor(model => model.Amount)
                 </div>                          
            </td>
        </tr>

我已经使用UltraEdit将.txt文件从ASCII转换为UTF-8.但是,我不确定如何在Windows环境中验证它是否为UTF-8格式.

谢谢!

如何用MVC3中的Web.Config值替换Range值？

[Range(5, 20, ErrorMessage = "Initial Deposit should be between $5.00 and $20.00")
public decimal InitialDeposit { get; set; }

web.config中:

<add key="MinBalance" value="5.00"/>
<add key="MaxDeposit" value="20.00"/>

有人可以给我一个Powershell脚本,它会将文件夹中所有文件的格式从Unicode更改为ANSI吗？这是一个示例文件夹结构:

c:\DBObjects
  +StoredProcs
      - sp1.sql
      - sp2.sql
      - sp3.sql
  +Views
     - v1.sql
     - v2.sql
  .Functions
     - fn1.sql
     - fn2.sql

我为一个文件尝试了以下脚本,它工作正常.但是它会创建另一个文件:

Get-Content sp1.sql -encoding Unicode | Set-Content sp1_Ansi.sql -encoding ASCII

谢谢!

以下jQuery自动完成代码未在MVC3中显示结果.当我调试代码时,我可以看到它正确调用QuickSearchByLastName.有人能告诉我我的代码是否不正确？(我也试过jquery-1.6.2.min.js但没有运气)谢谢!

Index.cshtml:

@using (Ajax.BeginForm(new AjaxOptions
{
    HttpMethod = "GET",
    InsertionMode = InsertionMode.Replace,
    UpdateTargetId = "results"
}
))
{               
    <input type="text" name="q" data-autocomplete="@Url.Action("QuickSearchByLastName","Search")"  />                 
}
<div id="results" >
</div>    


----------------------------------------------------------------
Search Controller:

    public ActionResult QuickSearchByLastName(string term)
            {
                using (var context = new CSCContext())
                {
                    var searchResults = context.Students
                                      .Where(s => s.LastName.Contains(term) && s.IsActive == true)
                                      .Take(10)
                                      .Select(s => new { label = s.LastName });


                    return Json(searchResults, JsonRequestBehavior.AllowGet);
                }                
            }

_Layout.cshtml:
    @Content.Script("jquery-1.4.4.min.js", Url)              
    @Content.Script("jquery.unobtrusive-ajax.min.js", Url)

如何为以下简单搜索条件编写动态Linq查询？1)StudentNumber 2)LastName 3)LastName和FirstName

//if (!String.IsNullOrEmpty(StudentNumber))
var results  = (from s in Students              
                where s.StudentNumber == 1001
                select s
               );

//else if (!String.IsNullOrEmpty(LastName) & (String.IsNullOrEmpty(FirstName))

var results  = (from s in Students              
                where s.LastName == "Tucker"
                select s
               );

//else if (!String.IsNullOrEmpty(LastName) & (!String.IsNullOrEmpty(FirstName))            
var results  = (from s in Students              
                where s.LastName == "Tucker" && s.FirstName == "Ron"
                select s
               );   

我在MVC3应用程序中有两个按钮.

   <input type="submit" name="command" value="Transactions" />  &nbsp;
   <input type="submit" name="command" value="All Transactions" />

当我单击一个按钮时,它会正确回发,但FormCollection没有"命令"键.我还在模型中添加了一个属性"command",并且在发布表单时它的值为null.

public ActionResult Index(FormCollection formCollection, SearchReportsModel searchReportsModel).         {
            if (searchReportsModel.command == "All Transactions")
              ...
            else
              ....
        }

我正在使用IE8.如何在MVC3中使用多个按钮？这个问题有解决方法吗？我做了很多研究,找不到解决方案.
更新:

戴夫:我尝试了你的解决方案,它正在抛出Http 404错误"无法找到资源".

这是我的代码:

[HttpPost]
[AcceptSubmitType(Name = "Command", Type = "Transactions")]
public ActionResult Index(SearchReportsModel searchReportsModel)
{
    return RedirectToAction("Transactions", "Reports", new { ...});
}

[HttpPost]
[ActionName("Index")]
[AcceptSubmitType(Name = "Command", Type = "All Transactions")]
public ActionResult Index_All(SearchReportsModel searchReportsModel)
{
   return RedirectToAction("AllTransactions", "Reports", new { ... });
}

public class AcceptSubmitTypeAttribute : …
