我正在構建一個猜字遊戲的管理界面,因此管理員用戶可以通過選擇將出現在遊戲中的單詞來設置遊戲,然後選擇單詞中的哪些字母將被編碼。ASP.net MVC 3在我的表格的每一行中處理多個複選框
MainGameTable編輯頁面.....
@model GameServer.ViewModels.GameTableModel
@section Javascript
{
<script src="@Url.Content("~/Scripts/jquery.validate.min.js")" type="text/javascript"></script>
<script src="@Url.Content("~/Scripts/jquery.validate.unobtrusive.min.js")" type="text/javascript"></script>
}
@{
ViewBag.Title = "GameTableEdit";
Layout = "~/Views/Shared/_Layout.cshtml";
}
<h2>GameTableEdit</h2>
@using (Html.BeginForm("GameTableEdit", "Admin", FormMethod.Post, new { enctype = "multipart/form-data" }))
{
@Html.ValidationSummary(true)
<fieldset>
<legend>GameTable</legend>
@Html.HiddenFor(model => model.GameTableId)
@Html.HiddenFor(model => model.GameTableNumber)
<div class="editor-label">

</div>
<div class="editor-label">
@Html.LabelFor(model => model.SubjectId)

<p>
<button type="submit" name="button" value="Save">Save</button>
</p>
</fieldset>
}
<div>
@Html.ActionLink("Back to List", "Index")
</div>
部分Page_for每個表中的單詞
@model GameServer.ViewModels.GameTableModel
@if (Model.SelectedLinewords.Count != null && Model.SelectedLinewords.Count > 0)
{
<table>
<tr>
<th>
Select Word
</th>
<th>
LineWord
</th>
<th>
Characters to Display
</th>
</tr>
@Html.EditorFor(x => x.SelectedLinewords)
</table>
}
的編輯器模板的每一行:
@model GameServer.ViewModels.SelectedLineWord
<tr>
<td>
@Html.CheckBoxFor(x => x.isSelected)
</td>
<td>
@Html.DisplayFor(x => x.LineWord)
</td>
<td>
@Html.HiddenFor(x=>x.LineWordId)
@Html.HiddenFor(x=>x.LineWord)
@{ char[] lineword = Model.LineWord.ToCharArray(); }
@for (int i = 0; i < Model.LineWord.Length; i++)
{
<input type="checkbox" name="DisplayCharPosition" value="@i" /> @lineword[i]
}
</td>
</tr>
這裏是我的ViewModel
public class SelectedLineWord
{
[Required]
public Guid LineWordId { get; set; }
[Required]
public String LineWord { get; set; }
public int[] DisplayCharPosition { get; set; }
[Required]
public bool isSelected { get; set; }
public SelectedLineWord()
{
}
public SelectedLineWord(Guid linewordid, String word, String displaycharposition)
{
LineWordId = linewordid;
LineWord = word;
String[] pos = displaycharposition.Split(',');
DisplayCharPosition = new int[word.Length];
for (int i = 0; i < word.Length; i++)
{
DisplayCharPosition[i] = 0;
}
for (int i = 0; i < pos.Length; i++)
{
DisplayCharPosition[Int32.Parse(pos[i])] = 1;
}
}
public SelectedLineWord(Guid linewordid, String word, bool issel)
{
LineWordId = linewordid;
LineWord = word;
isSelected = issel;
}
}
public class GameTableModel
{
[Required]
public Guid GameTableId { get; set; }
[Required]
public Guid GameMatrixId { get; set; }
[Required]
[Display(Name = "Table Subject")]
public int SubjectId { get; set; }
[Required]
[Display(Name = "Minimum Complexity")]
public int ComplexityId { get; set; }
[Required]
public int GameTableNumber { get; set; }
[Required]
[Display(Name = "Include a Bonus table")]
public bool IsBonus { get; set; }
[Display(Name = "Table Subject")]
public Dictionary<int, string> Subjects;
[Display(Name = "Minimum Complexity")]
public Dictionary<int, int> Complexities;
public List<GameTableLine> GameTableLines { get; set; }
public List<SelectedLineWord> SelectedLinewords { get; set; }
public GameTableModel()
{
try
{
//get a connection to the database
var data = new GameServerDataModelDataContext();
//Fetch the subjects reference data
var subjects = from c in data.Subjects orderby c.Subject1 select new { c.SubjectId, c.Subject1};
Subjects = new Dictionary<int, string>();
foreach (var subject in subjects)
{
Subjects.Add(subject.SubjectId, subject.Subject1);
}
//Fetch the complexities questions
Table<Complexity> dComplexities = data.GetTable<Complexity>();
Complexities = new Dictionary<int, int> { { 0, 0 } };
foreach (var complexity in dComplexities)
{
if (complexity.Complexity1 != null)
Complexities.Add(complexity.ComplexityId, (int)complexity.Complexity1);
}
}
catch (Exception ex)
{
//[TODO: Complete the exception handeling code.]
}
}
}
我的問題是,當我點擊保存按鈕時,傳遞給控制器的模型已經正確填充了所有內容,但是爲DisplayCharPosition選擇的複選框返回null。我期待的是一個int []填充了選擇顯示的字符的索引。
有人能幫我理解我做錯了什麼嗎?
我沒有得到任何迴應,所以我已經關閉的問題,並接受我自己的答案。 – Sheedy75
