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;
        }
    }
