我正在使用asp.net mvc 4中的应用程序。这里我有一个名为Property as
的模型public class Property
{
public long ID { get; set; }
public long Property_ID { get; set; }
public string Images { get; set; }
public string Title { get; set; }
public long PID { get; set; }
public long Property_Type { get; set; }
public long PropertyDetail_Type { get; set; }
public long Country { get; set; }
public long State { get; set; }
public long City { get; set; }
public string Bedroom { get; set; }
public string Bathroom { get; set; }
public string Location { get; set; }
public decimal Price { get; set; }
public string Description { get; set; }
public string Area { get; set; }
public int Status { get; set; }
public string Purpose { get; set; }
public long User_ID { get; set; }
public DateTime Date { get; set; }
public string CityName { get; set; }
public string StateName { get; set; }
public string CountryName { get; set; }
public long Emp_ID { get; set; }
public int seqnum { get; set; }
[NotMapped]
public SelectList PropertyList { get; set; }
public IEnumerable<Property> PLIST { get; set; }
}
public class PropertyContext
{
SqlConnection con = new SqlConnection(System.Configuration.ConfigurationManager.AppSettings["SQLCONN"].ToString());
public IEnumerable<Property> GetPropertyList(long CityID, string Location, int Property, int Purpose, int Bedroom, int Bathroom, decimal Price1, decimal Price2)
{
con.Open();
SqlCommand cmdProperty = new SqlCommand("SP_CheckProperty", con);
cmdProperty.Parameters.AddWithValue("@City", CityID);
cmdProperty.Parameters.AddWithValue("@Location", Location);
cmdProperty.Parameters.AddWithValue("@Property", Property);
cmdProperty.Parameters.AddWithValue("@Purpose", Purpose);
cmdProperty.Parameters.AddWithValue("@Bedroom", Bedroom);
cmdProperty.Parameters.AddWithValue("@Bathroom", Bathroom);
cmdProperty.Parameters.AddWithValue("@Price1", Price1);
cmdProperty.Parameters.AddWithValue("@Price2", Price2);
cmdProperty.CommandType = CommandType.StoredProcedure;
SqlDataAdapter daProperty = new SqlDataAdapter(cmdProperty);
DataTable dtProperty = new DataTable();
daProperty.Fill(dtProperty);
Search obj = new Search();
con.Close();
return dtProperty.AsEnumerable().Select(row =>
{
return new Property
{
ID = Convert.ToInt64(row["ID"]),
Property_ID = Convert.ToInt64(row["Property_ID"]),
Images = Convert.ToString(row["Images"]),
Title = Convert.ToString(row["Title"]),
PID = Convert.ToInt64(row["PID"]),
Property_Type = Convert.ToInt64(row["Property_Type"]),
PropertyDetail_Type = Convert.ToInt64(row["PropertyDetail_Type"]),
Country = Convert.ToInt64(row["Country"]),
State = Convert.ToInt64(row["State"]),
City = Convert.ToInt64(row["City"]),
Bedroom = Convert.ToString(row["Bedroom"]),
Bathroom = Convert.ToString(row["Bathroom"]),
Location = Convert.ToString(row["Location"]),
Price = Convert.ToDecimal(row["Price"]),
Description = Convert.ToString(row["Description"]),
Area = Convert.ToString(row["Area"]),
Status = Convert.ToInt32(row["Status"]),
User_ID = Convert.ToInt64(row["User_ID"]),
Date = Convert.ToDateTime(row["Date"]),
CityName = Convert.ToString(row["CityName"]),
StateName = Convert.ToString(row["StateName"]),
CountryName = Convert.ToString(row["CountryName"]),
Emp_ID = Convert.ToInt64(row["Emp_ID"]),
seqnum = Convert.ToInt32(row["seqnum"])
};
});
}
}
在上面的类中有一个名为GetPropertyList的方法，它从Sql数据库中获取后获取一些参数并返回Properties列表。我有一个名为Home的控制器，它有一个名为DisplayDetails的动作，在表单提交后调用。此操作采用搜索类型的模型参数。这个名为search的模型具有相同的成员，在GetPropertyList方法中用作参数。我的行动是：
public ActionResult DisplayDetails(Search objCust)
{
if ((!string.IsNullOrEmpty(Request.Form["Bathroom"].ToString())) && (!string.IsNullOrEmpty(Request.Form["Bathroom"].ToString())) && (!string.IsNullOrEmpty(Request.Form["City"].ToString())) && (!string.IsNullOrEmpty(Request.Form["PropertyType"].ToString())) && (!string.IsNullOrEmpty(Request.Form["Purpose"].ToString())))
{
objCust.Bathroom = Convert.ToInt32((Request.Form["Bathroom"].ToString()));
objCust.Bedroom = Convert.ToInt32((Request.Form["Bedroom"].ToString()));
objCust.PropertyType = Convert.ToInt32((Request.Form["PropertyType"].ToString()));
objCust.Purpose = Convert.ToInt32((Request.Form["Purpose"].ToString()));
objCust.Maximum = Convert.ToDecimal(Request.Form["Maximum"].ToString());
objCust.Minimum = Convert.ToDecimal((Request.Form["Minimum"].ToString()));
objCust.Location = Convert.ToString((Request.Form["Location"].ToString()));
objCust.City = Convert.ToInt64(Request.Form["City"].ToString());
if (objCust.Minimum.ToString().Equals("1"))
objCust.Minimum = 1;
else
objCust.Minimum = Convert.ToDecimal(objCust.Min);
if ((objCust.Maximum.ToString().Equals("1")))
objCust.Maximum = 1;
else if ((objCust.Maximum.Equals("17")))
objCust.Maximum = 1;
else
objCust.Maximum = Convert.ToDecimal(objCust.Max);
PropertyContext MCon = new PropertyContext();
Property objProperty = new Property();
objProperty.PropertyList = new SelectList(MCon.GetPropertyList(objCust.City, objCust.Location, objCust.PropertyType, objCust.Purpose, objCust.Bedroom, objCust.Bathroom, objCust.Minimum, objCust.Maximum));
AutoComplete1.Models.IEnumerable<Property>{ objProperty.PropertyList});
return View("DisplayDetails", new List<Property> { objProperty });
}
else
{
Search objCity = new Search();
objCity.Property = new SelectList(MCon.GetPropertyList(), "ID", "PropertyName");
objCity.PurposeList = new SelectList(MCon.GetPurpose(), "ID", "PurposeName");
return View("Default", objCity);
}
}
我的显示详细信息视图是：
@model IEnumerable<AutoComplete1.Models.Property>
@{
ViewBag.Title = "DisplayDetails";
Layout = "~/Views/Shared/_Layout.cshtml";
}
<h2>DisplayDetails</h2>
<ul class="row">
@foreach (var item in Model)
{
var @impath = item.Images;
<li class="col-sm-4">
<!--======= TAGS =========-->
<span class="tag font-montserrat rent"> @Html.DisplayFor(modelItem => item.Purpose)</span>
<section>
<!--======= IMAGE =========-->
<div class="img"> <img class="img-responsive" src="@impath" alt="" />
<!--======= IMAGE HOVER =========-->
<div class="over-proper"> <a href="#." class="btn font-montserrat">more details</a> </div>
@*</div>*@
<!--======= HOME INNER DETAILS =========-->
<ul class="home-in">
<li><span><i class="fa fa-home"></i> @Html.DisplayFor(modelItem => item.Area)</span></li>
<li><span><i class="fa fa-bed"></i> @Html.DisplayFor(modelItem => item.Bedroom)</span></li>
<li><span><i class="fa fa-tty"></i> @Html.DisplayFor(modelItem => item.Bathroom)</span></li>
</ul>
<!--======= HOME DETAILS =========-->
<div class="detail-sec"> <a href="#." class="font-montserrat">sweet home for small family</a> <span class="locate"><i class="fa fa-map-marker"></i> @Html.DisplayFor(modelItem => item.Location), @Html.DisplayFor(modelItem => item.CityName)</span>
<p>@Html.DisplayFor(modelItem => item.Description) </p>
<div class="share-p"> <span class="price font-montserrat">@Html.DisplayFor(modelItem => item.Price)</span> <i class="fa fa-star-o"></i> <i class="fa fa-share-alt"></i> </div>
</div>
</section>
</li>
}
</ul>
这里的一切都运转良好。控制器操作DisplayDetails在表单提交上获得正确的参数。正确的Prroperty List来自数据库。但是当我将列表发送到视图时，它没有绑定到正确的值。任何人都可以在这里帮助我。
