我想要的結果是當我選中DropDownList中的值時,點擊BUTTON就可以將想要的結果在GridView中顯示出來,C#中該如何編寫此程序的代碼!Thanks and Best Regards!
代碼如下:  
<form id="form1" runat="server">
    <div>
        &nbsp;&nbsp;<br />
        &nbsp;
        <asp:DropDownList ID="DropDownList1" runat="server" DataSourceID="SqlDataSource1"
            DataTextField="部門名稱" DataValueField="部門名稱">
        </asp:DropDownList>
        <asp:Button ID="Button1" runat="server" OnClick="Button1_Click" Text="Button" />
        <asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:ConnectionString %>"
            ProviderName="<%$ ConnectionStrings:ConnectionString.ProviderName %>" SelectCommand='SELECT "部門名稱" FROM "MYEMPLOYEES"'>
        </asp:SqlDataSource>
        <asp:GridView ID="GridView1" runat="server">
        </asp:GridView>
    </div>
    </form>
