我搜索了並找不到答案我的問題有人可以幫忙嗎?我試圖將一個對象列表綁定到一個列表框。我有正確數量的項目(我仍然可以選擇它們),但我看不到文本。WPF綁定對象到列表框,文本不出現
我的XAML代碼:
<ListBox x:Name="listbox_leave" BorderThickness="0">
<ListBox.ItemTemplate>
<DataTemplate>
<StackPanel>
<TextBlock Text="{Binding leaveName}" />
<TextBlock Text="{Binding numberOfDays}" />
</StackPanel>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
這是後端代碼:
ObservableCollection<Leave> leavelist = new ObservableCollection<Leave>();
leavelist = DbControl.loadLeaveDetails();
listbox_leave.ItemsSource = leavelist;
和我的假類
class Leave
{
public string leaveName;
public string LeaveName
{
get { return leaveName; }
set { leaveName = value; }
}
public string numberOfDays;
public string NumberOfDays
{
get { return numberOfDays; }
set { numberOfDays = value; }
}
}
當我調試,休假ObservableCollection
列表中有所有正確的數據,我的列表框顯示空白,但它有正確數量的對象留在它(我可以選擇他們),但沒有文字顯示。我有這個味精:
System.Windows.Data Error: 40 : BindingExpression path error: 'leaveName' property not found on 'object' ''Leave' (HashCode=44930696)'. BindingExpression:Path=leaveName; DataItem='Leave' (HashCode=44930696); target element is 'TextBlock' (Name=''); target property is 'Text' (type 'String')
