如何检测列表视图滚动条上的双击? [英] How to detect double click on list view scroll bar?

问题描述

我在WPF上有两个列表视图.第一个列表视图加载了一个数据表.在第一个列表视图中双击一个项目时，selectedItem将移至第二个列表视图.

I have two list view on WPF. The first listview is loaded with a Datatable. When double clicking on one item from the first listview, the selectedItem is moved to the second listview.

由于从DataTable加载了很多元素，因此在第一个列表视图中出现滚动条时会出现问题.如果选择一个项目并双击滚动条向下箭头，则将启动MouseDoubleClick事件，并将所选项目移至第二个列表视图.

The problem arises when appears an scroll bar in the first list view due to a lot of elements loaded from the DataTable. If a select one item and double click on the scroll bar down arrow, MouseDoubleClick event is launched and the selected item is moved to the second listview.

我如何才能检测到滚动条上的双击来防止这种情况发生?

推荐答案

我测试了上面的代码，该代码非常有帮助，但发现以下代码更稳定，因为有时您实际上是双重的，有时将源报告为GridViewRowPresenter.点击一个项目.

I tested the above code which was very helpful, but found the following to be more stable, as sometimes the source gets reported as GridViewRowPresenter when in fact you are double clicking an item.

var src = VisualTreeHelper.GetParent((DependencyObject)e.OriginalSource);
var srcType = src.GetType();
if (srcType == typeof(ListViewItem) || srcType == typeof(GridViewRowPresenter))
{
    // Your logic here
}
