引自： www.cnblogs.com/pursuedream/articles/807397.html 运用鼠标事件point 类 Point mousePos = new Point(0,0); 在ListView的鼠标事件下          private void listView1_MouseMove( object sender, System.Windows.Forms.MouseEventArgs e)          {              // record mouse position              mousePos.X = e.X;              mousePos.Y = e.Y;          } 然后对ListView的双击事件处理        //found clicked item    ListViewItem item = listView1.GetItemAt(mousePos.X,mousePos.Y); //获取鼠标所点击在哪一列上 存在ListView产生滑块，这样就不能精确获得显示列的X，Y值，为获取滑块滑动的距离，可以使用API来得到 using System.Runtime.InteropServices;           [DllImport("user32")] public static extern int GetScrollPos(int hwnd, int nBar) ;                  // locate text box                  Rectangle rect = item.GetBounds(ItemBoundsPortion.Entire);                  int StartX = rect.Left;                  int ColumnIndex = 0 ;                  // get ColumnIndex                 //得到滑块的位置                 int pos = GetScrollPos(this. listView1 .Handle.ToInt32(),0);                  foreach (ColumnHeader Column in listView1.Columns)                  {                      if (mousePos.X + pos >= StartX + Column.Width)                      {                                                              StartX += Column.Width;                          ColumnIndex += 1 ;                      }                  }                  // locate the txtinput and hide it. txtInput为TextBox                  txtInput.Parent = listView1;                  // begin edit                  if (item != null )                  {                      rect.X = StartX;                      rect.Width = listView1.Columns[ColumnIndex].Width; //得到长度和ListView的列的长度相同                      txtInput.Bounds = rect;                      // show textbox                      txtInput.Text = item.SubItems[ColumnIndex].Text;                      txtInput.Visible = true ;                      txtInput.Focus();                  } 向ListView加载数据 ListViewItem item; foreach(DataRow dr in ds.Tables[0].Rows) {       item = new ListViewItem(dr[0].ToString());        item.subItem.add(dr[1].ToString());      ListView.Item.Add(item); }
