老生常谈了！对于动态树（可添加、删除、修改等操作），大家用什么动态树呀？接受了好的示例，另给加分！

[DoHope]

对于这种可以对其添加、删除、修改等操作的动态树，大家都用的是什么树？
1、对于微软的树，要解决它点击刷新的问题，是不是把它的postback设为false后，点击时用javascript来实现呀？是这样吗？
2、大家是否有好的建议，好的示例呀？

来来来，这里给你个例程，再给个我的网页上的TreeViwe看看，一万个子节点都没问题
。
http://dev1.eraserver.net/czc888/webform1.aspx
至于那三个图象的意义你看我的网页就知道了。分别表示一页纸（没有子节点）、一本
关闭的书（有子节点），一本打开的书（当前节点被展开）

void creat_node(string
name,Microsoft.Web.UI.WebControls.TreeNode t1,string number)
{
//定义一个新的结点

Microsoft.Web.UI.WebControls.TreeNode t2=new
Microsoft.Web.UI.WebControls.TreeNode();
t2.ID=number;
t2.Text=name;


//判断是否为根结点
TreeView1.ExpandedImageUrl="images/Depart03.bmp";
if(t1.ID.Trim()=="###")
{
TreeView1.Nodes.Add(t2);
t2.ImageUrl="images/Depart01.bmp";
}
else
{
t1.Nodes.Add(t2);
t2.ImageUrl="images/Depart01.bmp";
t1.ImageUrl="images/Depart02.bmp";
}


//取得这个结点的所有子结点，利用递归自动生成
string mySelectQuery = "SELECT ParentID, ID,Name FROM table1
where ParentID='" + number +"'";
string MyConnString="provider=Microsoft.Jet.OLEDB.4.0;Data
Source="+Server.MapPath(".")+"/dt/mydata.mdb";
OleDbConnection myConnection = new
OleDbConnection(MyConnString);
OleDbCommand myCommand = new
OleDbCommand(mySelectQuery,myConnection);
myConnection.Open();
OleDbDataReader myReader;
myReader = myCommand.ExecuteReader();
while (myReader.Read())
{
creat_node(myReader.GetString(2),t2,myReader.GetString(1));

}
myReader.Close();
myConnection.Close();

}

private void CreateProviderTreeBtn_Click(object sender,
System.EventArgs e)
{
Microsoft.Web.UI.WebControls.TreeNode t1=new
Microsoft.Web.UI.WebControls.TreeNode();
creat_node("",t1,"###");

经常能见到你。
　你的http://dev1.eraserver.net/czc888/webform1.aspx打不开呀？
　再就是你的树能对其添加、删除、修改？

[DoHope]

是否能在点击节点避免刷新呢？

[ccqhydzcc]

最好用第三方控件，微软哪个太不好用了如r.a.d TreeViwe

这个论坛怎么改呀？

顶！

有没有右键菜单的树呀？可以进行添加、重命名等操作了。
