HI，



使用 selectedIndexChanged 为您的目的的方法。下面的示例代码供参考。

Use the selectedIndexChanged method for your purpose. A sample code below for reference.

protected void ddlCountry_SelectedIndexChanged(object sender, EventArgs e)
   {
       IList<State> states = GetStateList(GetCountryList()[((DropDownList)sender).SelectedIndex]);
       ddlStates.DataSource = states;
       ddlStates.DataBind();
   }
