最近在做一个项目的时候,用到了Listview,需要选择一个item,来进行删除。
但是当开启了
PullToRefreshListViewControl.IsMultiSelectCheckBoxEnabled = true;
PullToRefreshListViewControl.SelectionMode = ListViewSelectionMode.Multiple;
点击Item还是进入了Listview的Click事件。。。。。。
这里我们就需要用到一个小技巧了,顶一个一个全局变量 bool bMultiSelect = false;
最终效果
在Click事件中,判断是不是多选即可。
现在在xaml中定义三个button,实际工作不需要这么多,我这方便说明演示
一个是开启多选模式,一个是取消多选模式,最后是删除事件
<Button Content="MultiSelect" Click="MultiSelectClick"/>
<Button Content="CancelMultiSelect" Click="CancelMultiSelectClick"/>
<Button Content="DeleteSelected" Click="DeleteSelectedClick"/>
对应的后台code
private void MultiSelectClick(object sender, RoutedEventArgs e)
{
bMultiSelect = true;
PullToRefreshListViewControl.IsMultiSelectCheckBoxEnabled = true;
PullToRefreshListViewControl.SelectionMode = ListViewSelectionMode.Multiple;
} private void CancelMultiSelectClick(object sender, RoutedEventArgs e)
{
bMultiSelect = false;
PullToRefreshListViewControl.IsMultiSelectCheckBoxEnabled = false;
PullToRefreshListViewControl.SelectionMode = ListViewSelectionMode.None;
} private async void DeleteSelectedClick(object sender, RoutedEventArgs e)
{
if (PullToRefreshListViewControl.SelectedItems.Count == )
{
Debug.WriteLine("No items selected");
return;
} for (int i = PullToRefreshListViewControl.SelectedItems.Count - ; i >= ; i--)
{
FaceSet fs = PullToRefreshListViewControl.SelectedItems[i] as FaceSet;
await FacePlusPlusHelper.DeletePersoninCloud(fs.FaceSetToken, fs.OuterId);
SampleItems.Remove(fs);
} if (SampleItems.Count == )
{
bMultiSelect = false;
PullToRefreshListViewControl.IsMultiSelectCheckBoxEnabled = false;
PullToRefreshListViewControl.SelectionMode = ListViewSelectionMode.None;
}
}
然后在Listview的点击事件中屏蔽一下即可
private async void PullToRefreshListViewControl_ItemClick(object sender, ItemClickEventArgs e)
{
if(bMultiSelect)
return; //然后这里写单击item的代码咯
}
o, 对了,PullToRefreshListViewControl是Listview控件。
