确定ListView中单击的列 [英] Determine clicked column in ListView

问题描述

我需要列在C＃

我从的如何确定在ListView 点击的列索引，但我不知道我应该怎么实现它。

I have some sample code from How to determine the clicked column index in a Listview but I'm not sure how I should implement it.

推荐答案

哎呀，大家都懒得张贴code。有三个步骤的流程：

Jeez, everyone's too lazy to post code. There are three steps to the process:

1. 使用获得鼠标位置 Control.MousePosition 并转换为客户区坐标。


2. 调用的HitTest 函数查找鼠标指向。此方法返回大量信息的对象，除了实际的列数等等...


3. 使用的IndexOf 找到列号。
搜索子项目阵列

1. Get the mouse position using Control.MousePosition and convert to client coordinates.
2. Call the HitTest function to find what the mouse is pointing to. This returns an object with lots of information except the actual column number so...
3. Search the subitems array using IndexOf to find the column number.

这里的code：

private void listViewMasterVolt_DoubleClick(object sender, EventArgs e)
{
    Point mousePosition = myListView.PointToClient(Control.MousePosition);
    ListViewHitTestInfo hit = myListView.HitTest(mousePosition);
    int columnindex = hit.Item.SubItems.IndexOf(hit.SubItem);
}
