gridview 里实现 DropDownList

   <asp:TemplateField HeaderText="负责人"> 

                <ItemTemplate> 
                    <%# Eval("Manager") %>//非编辑状态下此列显示的内容 
                </ItemTemplate> 
                <EditItemTemplate> 
                    <asp:DropDownList ID="ddlManager" runat="server"> 
                    </asp:DropDownList> 
                </EditItemTemplate> 
                <ControlStyle Width="50px" /> 
                <HeaderStyle Width="50px" /> 
                <ItemStyle Width="50px" /> 
            </asp:TemplateField>     
     
    在.cs中写如下事件： 
    protected void gridview1_RowDataBound(object sender,GridViewRowEventArgs e) 
    { 
        if (e.Row.RowType == DataControlRowType.DataRow) 
        { 
            if (e.Row.FindControl("ddlManager") != null) 
            { 
                DropDownList ddl = (DropDownList)e.Row.FindControl("ddlManager"); 
                string strSql = "select NameVc from v_UserList"; 
                ddl.DataSource = DataOperation.BindToControls(strSql);//将数据绑定到dropdownlist上 
                ddl.DataValueField = "NameVc"; 
                ddl.DataTextField = "NameVc"; 
                ddl.DataBind(); 
                ddl.SelectedValue = DataBinder.Eval(e.Row.DataItem, "ManagerVc").ToString();//使点击编辑后dropdownlist的当前值为原始值

                 
            } 
        } 
    }
