我有列表框,其中包含垂直列出的按鈕和相關數據,如下所示;找到列表項索引 - WP7
<ListBox Name="CTransactionList" Margin="0,0,0,0" >
<ListBox.ItemTemplate >
<DataTemplate>
<Button Width="400" Height="200" Background="#6A040B2E" Click="completetransact">
<Button.Content >
<StackPanel Orientation="Horizontal" Height="200" Width="400">
<Image Source="{Binding Type1}" Width="80" Height="80" VerticalAlignment="Top" Margin="0,40,0,0"/>
<StackPanel Orientation="Vertical" Height="200">

<TextBlock Width="100" FontSize="22" Text="Name:" Height="30"/>

<TextBlock Width="290" FontSize="14" Text="{Binding Def1}" Height="65" TextWrapping="Wrap" FontStyle="Italic"/>
</StackPanel>
</StackPanel>
</StackPanel>
</Button.Content>
</Button>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
而我用這些類綁定數據;
[DataContract]
public class CTransaction
{
[DataMember]
public String Date1 { get; set; }
[DataMember]
public String Amount1 { get; set; }
[DataMember]
public String Type1 { get; set; }
[DataMember]
public String Time1 { get; set; }
[DataMember]
public String Dis1 { get; set; }
[DataMember]
public String Def1 { get; set; }
[DataMember]
public String Cdate1 { get; set; }
[DataMember]
public String Strpt1 { get; set; }
[DataMember]
public String Endpt1 { get; set; }
[DataMember]
public int Index1 { get; set; }
public CTransaction(String date1, String amount1, String type1, String time1, String dis1, String def1, String cdate1, String strpt1, String endpt1,int index1)
{
this.Date1 = date1;
this.Amount1 = amount1;
this.Time1 = time1;
this.Dis1 = dis1;
this.Def1 = def1;
this.Cdate1 = cdate1;
this.Strpt1 = strpt1;
this.Endpt1 = endpt1;
this.Index1 = index1;
switch (type1)
{
case "FR":
this.Type1 = "Images/a.png";
break;
case "TA":
this.Type1 = "Images/b.png";
break;
case "DA":
this.Type1 = "Images/c.png";
break;
case "CC":
this.Type1 = "Images/mount.png";
break;
}
}
}
如上所示,我有一個名爲Index1的數據綁定,該數據綁定使用任意整數爲按鈕編制索引。我想用這段代碼刪除用戶指定的索引按鈕;我確切的願望是刪除點擊按鈕(即如果第二個按鈕被點擊,然後刪除第二個按鈕)。我試圖在其中嵌入一些索引(即索引1)來刪除它,但我找不到任何可能的方法;我也失敗了。
這是我試過的方式;
上面給出的移除代碼僅基於整個列表項目計數移除索引項目。我的意思是,例如,第一個元素總是有'0'索引。它不關心我的Index1數據(我可以通過selectedButton作爲sender方法檢索Index1數據)我希望我可以刪除包含用戶指定的Index1數據的按鈕。
我該怎麼做?
在此先感謝。 (Windows Phone 7的)
