Windows Mobile，如何重写ComboBox? [英] Windows Mobile, How to rewrite the ComboBox?

问题描述

我们知道，ComboBox的下拉列表的大小是固定的，因此我想将listview或datagrid放入组合框的下拉列表中.

但是我发现Windows.Forms.dll中不包含ToolStripControlHost和ToolStripDropDown.

那我该怎么办?请帮我 ！

非常感谢.

As we know, the size of the dropdownlist of the ComboBox is fixed, so I want to put a listview or datagrid into the droplist of the combobox.

But I found the ToolStripControlHost and ToolStripDropDown are not included in the Windows.Forms.dll.

So what can I do? Please Help me !

Thank you very much.

推荐答案

您可以使用Form.Controls集合在运行时添加新的ListView/DataGridView对象. ComboBox还具有一个OnDropDown事件(如果我没记错的话)，您可以将其挂接并显示它.

然后在Leave事件上或选择之后，再次使其不可见，将其从Form.Controls和Dispose()

You can use the Form.Controls collection to add a new ListView/DataGridView object at runtime. The ComboBox also has a OnDropDown event (if I remember correctly), that you can hook to position and show it.

Then on the Leave event or after a selection, make it invisible again, remove it from the Form.Controls and Dispose()
