處理點擊ListView的子項目

Question

如何處理點擊ListView（細節模式）的子項目？即我需要檢測到哪個列被點擊。

Answer 1

您需要通過它的位置，以確定該列：

private void listView_Click(object sender, EventArgs e) 
{ 
    Point mousePos = listView.PointToClient(Control.MousePosition); 
    ListViewHitTestInfo hitTest = listView.HitTest(mousePos); 
    int columnIndex = hitTest.Item.SubItems.IndexOf(hitTest.SubItem); 
} 

Answer 2

這是爲我工作得好：

private void listView_MouseDown(object sender, MouseEventArgs e) 
    { 
     var info = listView.HitTest(e.X, e.Y); 
     var row = info.Item.Index; 
     var col = info.Item.SubItems.IndexOf(info.SubItem); 
     var value = info.Item.SubItems[col].Text; 
     MessageBox.Show(string.Format("R{0}:C{1} val '{2}'", row, col, value)); 
    } 

Answer 3

可以按如下方式使用ListView.MouseClick事件：

private void listView_MouseClick(object sender, MouseEventArgs e) 
{ 
    // Hittestinfo of the clicked ListView location 
    ListViewHitTestInfo listViewHitTestInfo = listView.HitTest(e.X, e.Y); 

    // Index of the clicked ListView column 
    int columnIndex = listViewHitTestInfo.Item.SubItems.IndexOf(listViewHitTestInfo.SubItem); 

    ... 
}
