我是MVC的初學者,想知道如何通過綁定模型設置返回查看。這裏是例子。模型綁定在MVC中查看
public class DataTypes
{
public Guid ItemID { get; set; }
[Required()]
public string Name { get; set; }
[Required()]
public string Status { get; set; }
[Required()]
public DataModel DataModel { get; set; } // This is for Binding
}
public class DataModel
{
public string Activity { get; set; }
public DateTime ?DateTime { get; set; }
}
通過上述模型類,我成功地能夠從UI數據綁定到後端,但問題是,我怎麼能使用上述retrun相同的數據的用戶界面。我想下面的代碼,但是,當它周圍來設置vaules的綁定類(DataModel的)
this.dataType.ItemID = // Guid from stored vaule in DataBase
this.dataType.Name = // Name from stored vaule in DataBase
this.dataType.Status = // Status from stored vaule in DataBase
// Set the activity to UI - ERROR.....!!!!!!
// Error was NullReferenceException unhandled
this.dataType.DataModel.Activity = // Activity from stored vaule in DataBase
this.dataType.DataModel.DateTime = // DateTime from stored vaule in DataBase
return View(this.dataType);
任何工作,爲上述問題?
先感謝, HV
