关于在GridView模版里添加DropDownList实现根据下拉列表的不同选择gridview根据条件筛选显示。

 <div>
        &nbsp;<asp:GridView ID="GridView1"
        runat="server"
        BackColor="White"
        BorderColor="#DEDFDE"
        BorderStyle="None"
        BorderWidth="1px"
        CellPadding="4"
        ForeColor="Black"
        GridLines="Vertical"
        OnRowCreated="GridView1_RowCreated">
            <Columns>
                <asp:TemplateField>
                 <HeaderTemplate>
                  <asp:DropDownList
                   runat="server"
                   ID="dropdownlist1"
                   BackColor="NavajoWhite"
                   AutoPostBack="true"
                   >
                  <asp:ListItem Value="0" Text=" "/>
                  <asp:ListItem Value="1" Text="整箱"/>
                  <asp:ListItem Value="2" Text="散货"/>
                  <asp:ListItem Value="3" Text="自拼"/>
