Hi thi is my code xcan anybody tell me what i am doing wrong

i just need to bind this treeview to my list

You can only add TreeNode objects. For example:

List<TreeNode> nodes = new List<TreeNode>();
nodes.Add(new TreeNode("1"));
nodes.Add(new TreeNode("12"));
treeView1.Nodes.AddRange(nodes.ToArray());

or:
List<int> hello = new List<int>();
hello.Add(1);
hello.Add(12);
foreach (int value in hello) {
treeView1.Nodes.Add(value.ToString());
}

List<int> hello = new List<int>();
hello.Add(1);
hello.Add(12);
foreach (int value in hello) {
treeView1.Nodes.Add(value.ToString());
}

instead of adding i need to update it probably 1st become 7th or some data value will also change ;

What?

i mean the order can also change so every time its something like this is going to happens.......

i added first 3 nodes then
i changed 2 nodes values........ to something else
then i added 4 nodes between previous 2nd and 3rd node
this sort of suffling i am talking about.......
do u have ny idea how can i achieve this.......

the resolvetaskbar() fuction is the curcial point at this pointwhat i am doing is updating my list again and again.....
so i know i have todo something here........but what........ i cud nt get........
as i cant bind the treeview to a list with the help of data source.........

now can you help me.........

overall/......... how can i first aad nodes to tree view then clear them all and then again i have to add the same updated list....

or if you can sugest me some other good approach............

thanx in advance.........

I have no suffling idea what a resolvetaskbar() function is and what it has to do with TreeView. Explain your question to a buddy. Once he gets it, ask him to type the question.

actually...... i need to do few things if you people can understand my problem

1. i made a calss Task bar it has sme proprties........ that is a extending control.

and the issue is its a heirarical data.......

so in main aaplication i made a list of type task bar.........

now i just want to update this list into a tree view.....

the REsolveTaskbar() is a fucntion which keep refreshing my control....... even if u change somthing .....

so is my question is clea now...........
then i can expect my answe......


so at last i need the solution for same question i need to bind a list to tree view........
and dat is going to chnage like a sensex board..... at real time...... and the tree view need to be updated all the time.......

i changed 2 nodes values........ to something else
then i added 4 nodes between previous 2nd and 3rd node
this sort of suffling i am talking about.......
do u have ny idea how can i achieve this.......

Did you want to know how to add the 4th node between the 2nd and 3rd node? It doesn't matter whether you change the value of the 2nd node. You can invoke the Insert method of the Nodes collection to insert this 4th node in the specified location. Just like the following:

treeView1.Nodes.Insert(2, "4"); // This is used to add the 4th node between the 2nd and 3rd.


If I misunderstood you, please let me know.
