在ListView中使用DropDownList綁定資料……好麻煩

在Aspx頁中的代碼:

<EditItemTemplate>

    <asp:DropDownList ID="DropDownList1" runat="server">

        <asp:ListItem Value="男">男</asp:ListItem>

        <asp:ListItem Value="女">女</asp:ListItem>

    </asp:DropDownList>

</EditItemTemplate>

 添加事件:ItemUpdating和ItemCreated事件

 protected void ListView1_ItemUpdating(object sender, ListViewUpdateEventArgs e)

        {

            //在更新之前綁定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;

                    }

                }

            }

 protected void ListView1_ItemDataBound(object sender, ListViewItemEventArgs e)

                DropDownList ddlLinkType = (DropDownList)e.Item.FindControl("DropDownList1");

                ListViewDataItem lvDataItem = (ListViewDataItem)e.Item;

                DataRowView rowView = (DataRowView)lvDataItem.DataItem;

                if (ddlLinkType != null && rowView != null)

                    var linksRow = (DAL.DataSetLinks.T_LinksRow)rowView.Row;

                    ddlLinkType.SelectedValue = linksRow.LinkType;

        protected void ListView1_ItemInserting(object sender, ListViewInsertEventArgs e)

            DropDownList ddlLinkType = (DropDownList)e.Item.FindControl("DropDownList1");

            e.Values["LinkType"] = ddlLinkType.SelectedValue;

        protected void ListView1_ItemUpdating(object sender, ListViewUpdateEventArgs e)

            DropDownList ddlLinkType = (DropDownList)ListView1.Items[e.ItemIndex].FindControl("DropDownList1");

            e.NewValues["LinkType"] = ddlLinkType.SelectedValue;

    }
