Question

我在单一选区有一个名单Box,其中包含一些项目。我执行道,用户能够将项目重新排序为“rag”; 一切工作都很出色,但确实看着,因为如果 mo子倒, cur子正在转过一个项目,清单箱就自动选定一个项目。

To be specific: To disable flickering in some situations I only move items when the item is dragged more than half over another item. When I start dragging item1 over item2 to place it behind item2, I want item1 to be selected while dragging. What happens is that item2 gets selected as soon as the cursor moves over item2. How can I get rid of this behavior?

我已经在PreviewMouseMove试图将e.Handled = 变为实情,同时拖累一些物品,但是这赢得了一定帮助。

如欲见该守则,请登陆网站。这是一种行为,它使任何具有IList作为数据来源的清单箱能够通过拖拉来调整其内容。

Answer 1

我最干净的解决办法是继承项目,执行我自己的“座标”。

Answer 2

这可能推翻了下降部分,但你是否试图把名单BoxItem的 mo取掉? MSDN有。

希望这一帮助。

This is a ListView. And I did not go into the detail of you code. But I do PreviewMouseLeftButtonDown on the ListViewItem and I don t have the problem you describe.

 <ListView.ItemContainerStyle>
            <Style TargetType="{x:Type ListViewItem}">
                <EventSetter Event="PreviewMouseLeftButtonDown" Handler="ListView1Item_PreviewMouseLeftButtonDown" />
                <Setter Property="AllowDrop" Value="True" />
                <EventSetter Event="DragDrop.Drop" Handler="ListView1Item_DragDrop" />
                <Style.Triggers>                     
                    <DataTrigger Binding="{Binding DispDetail}" Value="False">
                        <Setter Property="Visibility" Value="Collapsed"/>
                    </DataTrigger>
                </Style.Triggers>
            </Style>
        </ListView.ItemContainerStyle>
