ASP.NET ListView中使用DropDownList绑定数据方法

在Aspx页中的代码:

    <asp教程:DropDownList ID="DropDownList1" runat="server">
        男
        女
   

 

 添加事件:ItemUpdating和ItemCreated事件

 protected void ListView1_ItemUpdating(object sender, ListViewUpdateEventArgs e)
        {
            //在更新之前绑定DropDownList
            DropDownList ddGender = (DropDownList)ListView1.Items[e.ItemIndex].FindControl("DropDownList1");
            e.NewValues["Gender"] = ddGender.SelectedValue;
        }
 

 

protected void ListView1_ItemCreated(object sender, ListViewItemEventArgs e)
        {
            if (e.Item.ItemType == ListViewItemType.DataItem)
            {
                DropDownList ddlGender = (DropDownList)e.Item.FindControl("DropDownList1");
                if (ddlGender != null)
                {
                    ListViewDataItem lvDataItem = (ListViewDataItem)e.Item;
                    DataRowView rowView = (DataRowView)lvDataItem.DataItem;
                    if (rowView != null)
                    {
                        var userRow = (DataSetUsers.UsersRow)rowView.Row;
                        ddlGender.SelectedValue = userRow.Gender;
                    }
                }
            }
        }
