Question

我正在使用MVC开发一个项目，但是还集成了ViewModel层。我正在使用两个不同的数据表。第一个称为用户。那有很多不同的属性。第二个称为UserProfile。里面只有用户名电子邮件和密码。这些表通过“用户编号”字段在数据库中链接。

我有一个视图，该视图允许创建用户，以及有关将使用下拉列表选择的商店定义，StoreOwnerDefinition，商店区域定义和商店类型定义的信息。如何从视图的下拉列表中选择所选择的信息到SQL数据库中。

这是我在Controller中拥有的：


       public ActionResult UserCreateNew()
            {


              DataTable dt = new DataTable();
              // Open UserStoreDefinition table and create a List.
              dt = new DataTable();
              string constr =
             string strSQL = 

              using (DataAccess da = new DataAccess(constr))
              {
                dt = da.GetDataTable(strSQL, CommandType.Text);
              }

              // Convert a DataTable to a list. 
              m.lstStoreDefinition = LinqExtensions.ToListof<UserStoreDefinition>(dt);

              dt = new DataTable();
              //strSQL = "StoreOwnerDefinitions";
              strSQL = "SELECT distinct StoreOwnerName, StoreOwnerNumber FROM UserStoreDefinition"
                + " WHERE (UserStoreDefinition.UserNumber = " + m.UserNumber + ")"
                + " AND (UserStoreDefinition.StoreOwnerNumber <> -1)";

              using (DataAccess da = new DataAccess(constr))
              {
                dt = da.GetDataTable(strSQL, CommandType.Text);
              }
              m.lstStoreOwnerDefinitions = LinqExtensions.ToListof<UserStoreDefinition>(dt);

              dt = new DataTable();
              //strSQL = "StoreRegionDefinitions";


              using (DataAccess da = new DataAccess(constr))
              {
                dt = da.GetDataTable(strSQL, CommandType.Text);
              }
              m.lstStoreRegionDefinitions = LinqExtensions.ToListof<UserStoreDefinition>(dt);

              dt = new DataTable();
              //strSQL = "StoreTypeDefinitions";
              strSQL = "SELECT distinct StoreTypeName, StoreTypeNumber FROM UserStoreDefinition"
              + " WHERE (UserStoreDefinition.UserNumber = " + m.UserNumber + ")"
              + " AND (UserStoreDefinition.StoreTypeNumber <> -1)";

              using (DataAccess da = new DataAccess(constr))
              {
                dt = da.GetDataTable(strSQL, CommandType.Text);
              }
              m.lstStoreTypeDefinitions = LinqExtensions.ToListof<UserStoreDefinition>(dt);

              # endregion

              return View(m);
            }

    ```

    In my View Model I have: 

    ```

    and in the View I have: 

    ```





    <div class="spacerBody">
        <h2 class="admin-home-link orange-titles orange-titles-large">@Html.ActionLink("Create Users", "AdminIndex")</h2>

        <div class="to-link navlinks"> @Html.ActionLink("Users", "UserList") | @Html.ActionLink("Manage User Role", "RoleManageUser")</div>

        <p>&nbsp;</p>
        @using (Html.BeginForm())
        {
            @Html.AntiForgeryToken()
            @Html.ValidationSummary(true)


            <fieldset>
                <legend>Registration Form</legend>
                <ol class="comtrexBlue-text">
                    <li>
                        @Html.LabelFor(m => m.UserName)
                        @Html.TextBoxFor(m => m.UserName)
                    </li>
                    <li>
                        @Html.LabelFor(m => m.Password)
                        @Html.PasswordFor(m => m.Password)
                    </li>
                    <li>
                        @Html.LabelFor(m => m.ConfirmPassword)
                        @Html.PasswordFor(m => m.ConfirmPassword)
                    </li>

                    <li>
                        @Html.LabelFor(m => m.Email)
                        @Html.TextBoxFor(m => m.Email)
                    </li>
                </ol>
                <button class="btn larger" type="submit">Create</button>
            </fieldset>

        }


      <div class="form-group">
        <div class="input-group-btn">
          <div class="btn-group btn-group-justified" data-toggle="buttons">
            <label class="btn btn-primary">
              @Html.DropDownList
            </label>
            <label class="btn btn-primary">
              @Html.DropDownList
            </label>
            <label class="btn btn-primary">
              @Html.DropDownList
            </label>
            <label class="btn btn-primary">
              @Html.DropDownList       </label>
          </div>
        </div>
      </div>
    </div>

我想我的第一步是从视图中获取下拉信息。不执行存储过程并传递参数不是。

Answer 1

您需要将表单发布回控制器，并传递表单数据：

1）在BeginForm中设置动作，控制器和方法

@Html.BeginForm("UserCreateNew", "CONTROLLERNAMEHERE", FormMethod.Post)

2）修改UserCreateNew操作以将表单数据作为UserCreateNewViewModel

public ActionResult UserCreateNew(UserCreateNewViewModel userData)
        {

userData然后应在表单中输入所有数据。
