来自数据库的 ASP.Net MVC 3 CheckBoxList

发布于 2024-12-06 14:37:43 字数 770 浏览 0 评论 0原文

我有一个名为的表

tb_role
id  role
1   admin
2   user
3   viewer

，视图如下：

<div style="width:50%; float:right;">
    <legend>User Role</legend>
       <table>
        <tr>
         <th>Role</th>
        </tr>
        <tr>
         <td align="center"><input type="checkbox" id="CBRole"/></td>
        </tr>
       </table>
</div>

我想问，如何从表中列出我的复选框（CBRole）？所以我的 CBRole 从我的表中列出。

非常感谢

假设我有这样的角色表：

tb_role
RoleId  Role_Name
     1  SalesCreate
     2  SalesEdit
     3  AgentCreate
     4  AgentEdit

我想在复选框中列出销售角色（SalesCreate 和 SalesEdit，所以它只有 2 个复选框），该怎么做？谢谢

从您的控制器中，您可以使用以下属性填充您的视图模型：

您的 RoleViewModel

public IList<int> RolesSelected { get; set; }
public MultiSelectList Roles { get; set; }

从处理 Get 调用的控制器（例如 /roles/edit/1 ）

 model.RolesSelected = new List<int>();

 //here the code to populate the eventually already selected roles (update case)

 model.Roles = new MultiSelectList(repository.GetRoles(), "Id", "Name", model.SettoriSelected);

执行类似的操作

 @foreach (var item in Model.Roles)
 {
   <div class="MyClass">
     <label for="@item.Value" class="MyClassForCheck">
       <input type="checkbox" id="@item.Value" name="RolesSelected" value="@item.Value" @(item.Selected ? "checked" : "") />@item.Text</label>
   </div>
 }

然后在您的视图中（在表单标记内），您将在控制器中回答 Post 部分，您将访问 RolesSelected 并检查 ID。

在示例中，我放置了一个 div，但您显然可以将其更改为您喜欢的内容。希望有帮助

From your controller you populate your view model with these properties:

Your RoleViewModel

public IList<int> RolesSelected { get; set; }
public MultiSelectList Roles { get; set; }

From controller that handles the Get call (/roles/edit/1 for example)

 model.RolesSelected = new List<int>();

 //here the code to populate the eventually already selected roles (update case)

 model.Roles = new MultiSelectList(repository.GetRoles(), "Id", "Name", model.SettoriSelected);

then in your view (inside a form tag) you will do something like this

 @foreach (var item in Model.Roles)
 {
   <div class="MyClass">
     <label for="@item.Value" class="MyClassForCheck">
       <input type="checkbox" id="@item.Value" name="RolesSelected" value="@item.Value" @(item.Selected ? "checked" : "") />@item.Text</label>
   </div>
 }

in the controller that answer the Post part you will access the RolesSelected with the IDs checked

In the example I have put a div, but yuo can change it to what you like obviously. Hope it helps
