My Model返回DataTable的集合，如下所示。如何使用MVC RAZOR將DataTable綁定到DropDownList？
如何使用MVC RAZOR將DataTable綁定到DropDownList？
對於每個DataTable，我想爲它創建一個表格行和一個下拉列表。
我嘗試下面的代碼：
foreach (DataTable dataTable in Model.ParameterDataSources)
{
<tr>
<th>
Filter:
</th>
<td>
@Html.DropDownList("ddlFilterDataSource", dataTable, "--Select One--")
</td>
</tr>
}
如何實現這一目標？

## razor ##
@Html.DropDownList("Country", new SelectList(Model.CountryList, "Value", "Text", Model.CountryList.SelectedValue), new { @id = "ddlist", @data_role = "none", style = "color: #fff; background-color: #fff; font-family: Arial, Helvetica, sans-serif; font-size: 10px; color: #333333; margin-left:3px; width:100%; height:20px;" })
## model ##
public class somename
{
public SelectList CountryList { get; set; }
}
public class Country
{
public string ID { get; set; }
public string Name { get; set; }
}
## Controller ##
public ActionResult index()
{
List<Country> objcountry = new List<Country>();
objcountry = GetCountryList();
SelectList objlistofcountrytobind = new SelectList(objcountry, "ID", "Name", 0);
model.CountryList = objlistofcountrytobind;
return View(model);
}
[HttpPost]
public ActionResult Analyze(AnalyzeModels model)
{
List<Country> objcountry = new List<Country>();
objcountry = GetCountryList();
SelectList objlistofcountrytobind = new SelectList(objcountry, "ID", "Name", 0);
model.CountryList = objlistofcountrytobind;
return View(model);
}
**************************************************
## function for GetCountryList##
public List<Country> GetCountryList()
{
DataTable reportDetailsTable = objCommon.GetDetails("tablename");
List<Country> objcountrty = new List<Country>();
int s = reportDetailsTable.Rows.Count;
for (int i = 0; i < s; i++)
{
string d1 = reportDetailsTable.Rows[i][1].ToString();
string d2 = reportDetailsTable.Rows[i][10].ToString();
objcountrty.Add(new Country { ID = d1, LName = d2 });
}
return objcountrty;
}
一個簡單的解決方案是將你的DataTable轉換爲DataView，你應該很好去。
//Controller Code
ViewBag.Employees = new SelectList(objDt.AsDataView(), "id", "name");
我發現所有其他方法非常混亂，所以我在我看來這樣做，似乎工作得很好。我使用vb.net
<select>
@Code
For Each row In Model.dataTable.Rows
@<option>@row(0)</option>
Next
End Code
</select>

的鏈接通過創建視圖特定模型來建議服務器端方法。你的意思是沒有好的方法來實現這個使用RAZOR如上？ – 2012-04-17 10:54:38
