情况是这样的，现在的节点移动是通过更改sqlser语句，然后再从新查询刷新一遍实现，能不能做成异步的？跪求，在线等！
问题补充：
是.NET
这是移动节点的代码：
Config cf = new Config();
Config cfGetTable = new Config();
string newPaixuCode = string.Empty;
string newDepartCode;
DepartInfo dinfo = new DepartInfo(departCode);
if (!dinfo.IsGetData)
{
throw new Exception("没有找到要移动的单位");
}
try
{
String d = VBFunction.Left(parentCode, 6);
if (VBFunction.IsNumeric(d) && VBFunction.Right(parentCode, 2) == "00")
{
throw new Exception("该单位下面不能够有单位");
}
if (departCode.Length <= parentCode.Length && departCode == VBFunction.Left(parentCode, departCode.Length))
{
throw new Exception("不能将单位移动到他的子单位下面");
}
//
int tempRecordcount = 1;
cf.TranBegin();
// '更新排序
DataTable rs1 =
cfGetTable.GetTable("select * from zb_DepartBasicInfo where left(单位代码,len(单位代码)-4)='" + parentCode +
"' and len(单位代码)=" +
(parentCode.Length + 4).ToString() + " order by 排序");
if (rs1.Rows.Count > 0)
{
for (int i = 0; i < rs1.Rows.Count; i++)
{
// rs1!排序 = rs1.AbsolutePosition
// rs1.Update()
UpdateSque(rs1.Rows[i]["单位代码"].ToString(), IntToCode(i), cf);
cf.TranRunSql("update ZB_DepartBasicInfo set 排序=" + i + " where 单位代码='" + rs1.Rows[i]["单位代码"] + "'");
// rs1.MoveNext()
}
tempRecordcount = rs1.Rows.Count;
}
// '获得新的单位代码
// ExtendCode = GetNewDepartCode(parentCode, "DepartBasicInfo");
newDepartCode = GetNewDepartCode(parentCode);
//
//
//获得新的排序码
DataTable rs;
if (parentCode.Length == 6)
rs = cfGetTable.GetTable("select 排序 from zb_code where 行政区划代码='" + parentCode + "'");
else
rs = cfGetTable.GetTable("select 整体排序 as 排序 from zb_DepartBasicInfo where 单位代码='" + parentCode + "'");
if (rs != null)
newPaixuCode = rs.Rows[0]["排序"] + IntToCode(tempRecordcount);
//
// //判断单位是否重复
// rs =
// cfGetTable.GetTable ("select count(*) from zb_DepartBasicInfo where 单位名称='" + dinfo.DepartName
// + "' and 单位代码!='" + departCode +
// "' and left(单位代码,6) ='" + VBFunction.Left(parentCode, 6) + "'");
// if (VBFunction .CInt (rs.Rows[0].ToString())> 0)
// throw new Exception("在该地区已经存在该单位");
//
// '开始修改单位信息
cf.TranRunSql("update zb_DepartBasicInfo set 单位代码='" + newDepartCode + "' + Right(单位代码,len(单位代码)-" +
departCode.Length +
"), 排序='" + tempRecordcount + "', 整体排序= '" + newPaixuCode + "' + Right(整体排序,len(整体排序)-" +
departCode.Length +
"-1) where left(单位代码,len('" + departCode + "'))='" + departCode + "'");
for (int i = 1; i <= 16; i++)
cf.TranRunSql("update zb_gj" + i + " set 单位代码='" + newDepartCode + "' + Right(单位代码,len(单位代码)-" +
departCode.Length + ") where left(单位代码,len('" + departCode + "'))='" + departCode + "'");
// cf.RunSql ("update codeinfo set 单位代码='" & newDepartCode & "' & Right(单位代码,len(单位代码)-" & Len(LblDepartCode) & ") where left(单位代码,len('" & LblDepartCode & "'))='" & LblDepartCode & "'")
// ChangeDepartCode = newDepartCode
// WriteGrid(getSql(newDepartCode))
//
// FrmBasicInfo.TreeVeiwRefreah()
// FrmExBasicInfo.TreeVeiwRefreah()
//
// FrameMove.Visible = False
// MsgBox "移动操作完成后,请确认单位基本信息是否需要修改。若需要修改请进入“修改单位信息”窗口，进行修改！"
// Exit Sub
//Errorend:
// MsgBox(err.Description)
cf.TranEnd();
}
catch (Exception ex)
{
cf.TranRollback();
throw (ex);
}

把这个treeview 放进updatePanel控件里。

能稍微详细的说一下嘛？那这些后台的代码呢，不用动还是？
@浮生丶若梦灬: 如果你是webform页面。有个控件叫updatePanel.你把treeView外面套上updatePanel就行了。
@Firen: 恩恩，我在网上看教程了，但是我自己新建的页面有用，放到那个项目里边就没效果了。。你能帮我看一下那个代码吗？
@浮生丶若梦灬: 项目里的framework是什么版本的？
@Firen: IIS的framework也要设置到相应版本。
@Firen: 大哥，那个怎么看。。新手表示没找到。。
@Firen: 不过这个项目好像是05年左右的。。
@Firen: 大哥，还在吗？
@浮生丶若梦灬: 05年的时候应该是framework2.0 你只要升级到3.5以上就行了。
@Firen: 现在显示是4.0

麻烦看下，这段代码我加的updatapanel位置对吗？
@浮生丶若梦灬: 你调试下看看对不对不就行了…
