推荐答案

DropDownList控件的OnSelectedIndexChanged事件，您可以在列表中填充适当的数据.

OnSelectedIndexChanged event of DropDownList control, you can fill the appropriate data in the list.

<aspropdownlist cssclass="TxtBox" id="Project" runat="server" tabindex="13" autopostback="true" onselectedindexchanged="Project_SelectedIndexChanged"></aspropdownlist>

Project_SelectedIndexChanged事件将填充相邻的DropDownList控件.

Project_SelectedIndexChanged event will fill the adjacent DropDownList control.
