ListView单击单元格 产生其他控件

  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 > )
{
//获得选中的行
ListViewItem item = this.listView1.SelectedItems[];
//获得行号
int index=this.listView1.SelectedIndices[];
cmds[index] = new ComboBox();
for (int i = ; i <= ; i++){
cmds[index].Items.Add(i + "");
cmds[index].SelectedItem = "";
cmds[index].Bounds = item.SubItems[].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 = ;
  int pos = GetScrollPos(this.indicatorView.Handle.ToInt32(), );
  foreach (ColumnHeader Column in indicatorView.Columns)//选中的哪一列
  {
    if (mousePos.X + pos >= StartX + Column.Width)
    {
      StartX += Column.Width;
      ColumnIndex += ;
    }
  }
  if (ColumnIndex == this.indicatorView.Columns.Count - )//如果选中最后一列
  {
    int index = this.indicatorView.SelectedIndices[];
    indicatorViewComboBox[index] = new ComboBox();
    for (int i = ; i <= ; i+=)
      indicatorViewComboBox[index].Items.Add(i + "");
    indicatorViewComboBox[index].SelectedItem = "";
    indicatorViewComboBox[index].Bounds = item.SubItems[ColumnIndex].Bounds;
    indicatorView.Controls.Add(indicatorViewComboBox[index]);
    indicatorViewComboBox[index].Show();
  }
  else if (ColumnIndex == this.indicatorView.Columns.Count - ) { //其他列
  
  } }
