我有以下列表视图:
单击父行中的红色按钮时,我想显示从属行。通过第二次单击,应再次隐藏行。
我是 WPF 的新手,不知道 1.如何获得可扩展/可折叠的行和 2.如何在父行和子行之间创建关系。
我的 XAML 如下:
<ListView Name="lvUpgrade">
<ListView.View>
<GridView>
<GridViewColumn Width="20px">
<GridViewColumn.CellTemplate>
<DataTemplate>
<Image Source="{Binding Path=Icon}" />
</DataTemplate>
</GridViewColumn.CellTemplate>
</GridViewColumn>
<GridViewColumn Width="75px" DisplayMemberBinding="{Binding Path=Time, StringFormat={}{0:HH:mm:ss}}" />
<GridViewColumn Width="300px" Header="Nachricht" DisplayMemberBinding="{Binding Path=Message}" />
</GridView>
</ListView.View>
</ListView>
后面的代码:
Public Class Upgrade
Public Sub AddMessage(ByVal message As Message)
Me.lvUpgrade.Items.Add(message)
End Sub
Public Class Message
Public Enum MessageType
Normal
Information
Success
Warning
[Error]
End Enum
Public Sub New(ByVal type As MessageType, ByVal message As String)
_Type = type
_Message = message
End Sub
Private _Type As MessageType = MessageType.Normal
Public ReadOnly Property Type As MessageType
Get
Return _Type
End Get
End Property
Private _Message As String = String.Empty
Public ReadOnly Property Message As String
Get
Return _Message
End Get
End Property
Private _Time As DateTime = Now
Public ReadOnly Property Time As DateTime
Get
Return _Time
End Get
End Property
Public ReadOnly Property Icon As BitmapImage
Get
Select Case Me.Type
Case MessageType.Information
Return My.Resources.Information16.ToBitmapImage
Case MessageType.Success
Return My.Resources.OK16.ToBitmapImage
Case MessageType.Warning
Return My.Resources.Alert16.ToBitmapImage
Case MessageType.Error
Return My.Resources.Error16.ToBitmapImage
Case Else
End Select
Return Nothing
End Get
End Property
End Class
End Class
