以combobox为例。

  假如一行里面只有一个combobox。

    //在类中声明一个控件数组
    private ComboBox[] cmds = null;

    //initview中调用dao组件获得显示的对象列表
    List<Indicator> plist = idao.queryIndicators();

    //根据对象列表个数new一组cmds
    cmds=new ComboBox[plist.Count];

    //在view的SelectedIndexChanged事件中
    if (this.listView1.SelectedItems.Count > 0)
    {
        //获得选中的行
        ListViewItem item = this.listView1.SelectedItems[0];
        //获得行号
        int index=this.listView1.SelectedIndices[0];
        cmds[index] = new ComboBox();
        for (int i = 1; i <= 50; i++){
            cmds[index].Items.Add(i + "");
            cmds[index].SelectedItem = "20";
            cmds[index].Bounds = item.SubItems[3].Bounds;
            listView1.Controls.Add(cmds[index]);
            cmds[index].Show();
        }        
}

 

   如果一行有多个combobox呢? 这和一行一个的区别在于,一行两个不仅需要确定选中的是哪行,还要确定哪列。

  虽然只差这一点,但是实现确完全不同。


  private void indicatorView_MouseMove(object sender, MouseEventArgs e)//获取鼠标位置
  {
    mousePos.X = e.X;
    mousePos.Y = e.Y;
  }


private
void indicatorView_Click(object sender, EventArgs e) {   ListViewItem item = indicatorView.GetItemAt(mousePos.X, mousePos.Y);//根据鼠标当前位置得到item   Rectangle rect = item.GetBounds(ItemBoundsPortion.Entire);   int StartX = rect.Left;   int ColumnIndex = 0;   int pos = GetScrollPos(this.indicatorView.Handle.ToInt32(), 0);   foreach (ColumnHeader Column in indicatorView.Columns)//选中的哪一列   {     if (mousePos.X + pos >= StartX + Column.Width)     {       StartX += Column.Width;       ColumnIndex += 1;     }   }   if (ColumnIndex == this.indicatorView.Columns.Count - 1)//如果选中最后一列   {     int index = this.indicatorView.SelectedIndices[0];     indicatorViewComboBox[index] = new ComboBox();     for (int i = 0; i <= 50; i+=10)       indicatorViewComboBox[index].Items.Add(i + "");     indicatorViewComboBox[index].SelectedItem = "20";     indicatorViewComboBox[index].Bounds = item.SubItems[ColumnIndex].Bounds;     indicatorView.Controls.Add(indicatorViewComboBox[index]);     indicatorViewComboBox[index].Show();   }   else if (ColumnIndex == this.indicatorView.Columns.Count - 2) { //其他列      } }
