這是我的代碼,當我運行它時,輸出是什麼。我真的在這一個損失。任何幫助,將不勝感激。我需要將observablecollection添加到observablecollection。
VALIDATIONITEM CLASS:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Collections.ObjectModel;
namespace ValidationWPF.DataSources
{
public class ValidationItem : ObservableCollection<ValidationItem>
{
public ValidationItem()
{
SubItems = new ObservableCollection<ValidationItem>();
}
public ObservableCollection<ValidationMessages> Messages
{
get;
set;
}
public string item
{
get;
set;
}
public IList<ValidationItem> SubItems
{
get;
set;
}
public static IList<ValidationItem> GetItems(string name)
{
var Validation = new ObservableCollection<ValidationItem>();
var item = new ValidationItem();
item.item = "Customer";
var subItem = new ValidationItem();
subItem.item = "Name";
item.SubItems.Add(subItem);
var Message = new ValidationItem();
Message.item = new ObservableCollection<ValidationMessages>().ToString();
subItem.SubItems.Add(Message);
Validation.Add(item);
return Validation;
}
}
}
VALIDATIONMESSAGES CLASS(需要實現到驗證項目類)
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Collections.ObjectModel;
namespace ValidationWPF.DataSources
{
public class ValidationMessages
{
public ValidationMessages(string Message)
{
this.Message = Message;
}
public string Message
{
get;
set;
}
}
}
VALIDATIONUSERCONTROL XAML:
<UserControl x:Class="ValidationWPF.ValidationUserControl"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:telerik="http://schemas.telerik.com/2008/xaml/presentation"
xmlns:local="clr-namespace:ValidationWPF.DataSources"
mc:Ignorable="d"
d:DesignHeight="300" d:DesignWidth="300">
<UserControl.Resources>
</UserControl.Resources>
<Grid x:Name="LayoutRoot" Background="White">
<telerik:RadTreeView x:Name="radTreeView" Margin="8">
<telerik:RadTreeView.ItemTemplate>
<HierarchicalDataTemplate ItemsSource="{Binding SubItems}">
<TextBlock Text="{Binding item}" />
</HierarchicalDataTemplate>
</telerik:RadTreeView.ItemTemplate>
</telerik:RadTreeView>
</Grid>
</UserControl>
OUTPUT:
Customer
Name
Message Below*
*System.Collections.ObjectModel.ObservableCollection'1[ValidationWPF.DataSources.ValidationMessages]
但我的輸出需要包含我在驗證消息類中設置的消息。相反,它包含:System.Collections.ObjectModel.ObservableCollection'1 [ValidationWPF.DataSources.ValidationMessages] – JLott
