我有 ItemsControl 绑定到 ObservableCollection,一切都很好,除非 ObservableCollection 为空,ItemsControl 将显示一个空行!
<ItemsControl Visibility="Visible" ItemsSource="{Binding ocItemsinInvoice,Mode=TwoWay}"
x:Name="test" Margin="10,-32,0,207" Width="412" HorizontalAlignment="Left">
<ItemsControl.ItemsPanel>
<ItemsPanelTemplate>
<UniformGrid Columns="1" VerticalAlignment="Top" />
</ItemsPanelTemplate>
</ItemsControl.ItemsPanel>
<ItemsControl.ItemTemplate>
<DataTemplate>
<Button x:Name="btnOpenInvoice" Style="{StaticResource OpenInvoicesButton}"
FontSize="12" Width="300" Height="60" Foreground="#ff252526">
<StackPanel Orientation="Vertical">
<TextBlock Text="{Binding Item.ItemName}"
HorizontalAlignment="Center" VerticalAlignment="Center" />
</StackPanel>
</Button>
</DataTemplate>
</ItemsControl.ItemTemplate>
</ItemsControl>
我怎样才能删除它?
