Question

你好我用asp.net mvc 4开发一个应用程序，并且我使用kendo添加DataGridView！我有一些麻烦：

我想在datagridview

中为列添加两个属性

我有一个模特＆＃34;用户＆＃34;和模型＆＃34;项目＆＃34; 当用户创建新项目时，我必须将他的姓名和姓氏添加到datagridview 这是我的界面：

这是我的控制者：

＆＃13;

 public ActionResult Projet_Read([DataSourceRequest]DataSourceRequest request)
        {
            var projets = (from a in db.Projets
                          join b in db.Utilisateurs on a.UtilisateurID equals b.UtilisateurID
                          select new 
                          { 
                              ProjetId=a.ProjetId,
                              nomP=a.nomP,
                              DateDebut=a.DateDebut,
                              DateFinPrevue=a.DateFinPrevue,
                              DateFinReele=a.DateFinReele,
                              etat=a.etat,
                              Description=a.Description,
                              U=b.Prenom // U=b.Prenom +" "+b.Nom
                          });
            DataSourceResult result = projets.ToDataSourceResult(request, projet1 => new
            {
                ProjetId = projet1.ProjetId,
                nomP = projet1.nomP,
                DateDebut = projet1.DateDebut,
                DateFinPrevue = projet1.DateFinPrevue,
                DateFinReele = projet1.DateFinReele,
                Description = projet1.Description,
                etat = projet1.etat,
                U=projet1.U
            });
             return Json(result);
        }

＆＃13;

这是我的观点：

＆＃13;

<legend class="legend">Tous Les Projets</legend>
@{
    Layout = "~/Views/Shared/admin.cshtml";
}
<link href="~/Content/Gridmvc.css" rel="stylesheet" />
<script src="~/Scripts/gridmvc.js"></script>
<script src="~/Scripts/gridmvc.min.js"></script>
<div class="container-fluid placeholders">
    <div style="height:850px">
        @(Html.Kendo().Grid<mvc_depences.Models.Projet>()
        .Name("grid")
        .Columns(columns =>
        {
            columns.Bound(c => c.U).Title("Chef de Projet").Width(145);
            columns.Bound(c => c.nomP).Title("Nom Projet");
            columns.Bound(c => c.DateDebut).Title("Date Debut");
            columns.Bound(c => c.DateFinPrevue).Title("Date Fin Prevue");
            columns.Bound(c => c.DateFinReele).Title("Date Fin Réelle");
            columns.Bound(c => c.etat).Title("Etat");
            columns.Bound(c => c.Description).Title("Description");
            columns.Command(command => { command.Edit().Text("Modifier"); }).Width(150);   
        })
      .Editable(editable => editable.Mode(GridEditMode.PopUp))
      .Pageable()
      .Selectable(selectable =>
      {
          selectable.Mode(GridSelectionMode.Single);
          selectable.Type(GridSelectionType.Row);
      })
      .Filterable()
      .Scrollable()
      .DataSource(dataSource => dataSource
          .Ajax()
          .Model(model => model.Id(p => p.ProjetId))
          .Read(read => read.Action("Projet_Read", "Projet"))
          .Update(update => update.Action("Projet_Update", "Projet"))
      )
        )
    </div>
</div>

Answer 1

嗯，我没有使用过Kendo UI的经验。我的猜测是你尝试在SQL查询中连接字符串。您可以尝试首先获取所有数据（包括姓氏和姓氏）并将其映射到您的视图中。

控制器：

@app.route('/callback')
def callback_handling():
    env = os.environ
    code = request.args.get('code')

    json_header={'Content-Type': 'application/x-www-form-urlencoded'}

    token_url = "https://{domain}/oauth/token".format(domain='mydomain')

    token_payload = {
        'client_id': 'myid',
        'client_secret': 'mysecret',
        'redirect_uri': 'http://localhost:8080/callback',
        'code': code,
        'grant_type': 'authorization_code'
    }
    encoded = urllib.urlencode(token_payload)



    user_url = "https://{domain}/userinfo?access_token={access_token}"\
            .format(access_token=token_info['access_token'])

user_info = urlfetch.Fetch(user_url, method=urlfetch.GET, headers=json_header)

    session['profile'] = user_info
    return redirect('/dashboard')

在视图中：

public ActionResult Projet_Read([DataSourceRequest]DataSourceRequest request)
        {
            var projets = (from a in db.Projets
                          join b in db.Utilisateurs on a.UtilisateurID equals b.UtilisateurID
                          select new 
                          { 
                              ProjetId = a.ProjetId,
                              nomP = a.nomP,
                              DateDebut = a.DateDebut,
                              DateFinPrevue = a.DateFinPrevue,
                              DateFinReele = a.DateFinReele,
                              etat = a.etat,
                              Description = a.Description,
                              Prenom = b.Prenom,
                              Nom = b.Nom
                          });
            DataSourceResult result = projets.ToDataSourceResult(request, projet1 => new
            {
                ProjetId = projet1.ProjetId,
                nomP = projet1.nomP,
                DateDebut = projet1.DateDebut,
                DateFinPrevue = projet1.DateFinPrevue,
                DateFinReele = projet1.DateFinReele,
                Description = projet1.Description,
                etat = projet1.etat,
                Prenom = projet1.Prenom,
                Nom = projet1.Nom
            });
             return Json(result);
        }

这应该可以解决问题

我刚刚在sql请求中进行了连接，并且我保持其他代码不变！

public ActionResult Projet_Read([DataSourceRequest]DataSourceRequest request)
        {
            var projets = (from a in db.Projets
                          join b in db.Utilisateurs on a.UtilisateurID equals b.UtilisateurID
                          select new 
                          { 
                              ProjetId=a.ProjetId,
                              nomP=a.nomP,
                              DateDebut=a.DateDebut,
                              DateFinPrevue=a.DateFinPrevue,
                              DateFinReele=a.DateFinReele,
                              etat=a.etat,
                              Description=a.Description,
                              U=b.Prenom +" "+ b.nom
                          });
            DataSourceResult result = projets.ToDataSourceResult(request, projet1 => new
            {
                ProjetId = projet1.ProjetId,
                nomP = projet1.nomP,
                DateDebut = projet1.DateDebut,
                DateFinPrevue = projet1.DateFinPrevue,
                DateFinReele = projet1.DateFinReele,
                Description = projet1.Description,
                etat = projet1.etat,
                U=projet1.U,
            });
             return Json(result);
        }

DataSourceRequest将属性添加到网格视图kendo
