推荐答案

亲爱的朋友，

您必须编写组合框选择的索引已更改事件，更改后可以获取国家/地区的ID，然后可以从中获取该国家/地区的相应州并相应地填充状态组合框.

Dear Friend,

You have to write the combobox selected index changed event on the change of which you can get the ID of the country and from there you can fetch the corresponding states of that country and fill the combo box of states accordingly.

Please refer this:-http://msdn.microsoft.com/en-us/library/system.windows.forms.combobox.selectedindexchanged.aspx[^]

I hope this will help you out.

Thanks

您好，

您可以在combobox1_SelectedIndexChanged事件上绑定第二个组合框.
