在Aspx页中的代码:

 

<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;
                    }
                }
            }
        }

 

 

 protected void ListView1_ItemDataBound(object sender, ListViewItemEventArgs e)
        {
            if (e.Item.ItemType == ListViewItemType.DataItem)
            {
                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;
        }
    }
