How to find node in TreeView by using string(the same as Node.Text) ?

[jiing]

Hi all,

I want to use sting(the same as Node.Text) to judge if a node exists
in TreeView.
I've tried several ways, but seems all failed.

could anybody help me?

Thanks in advance.
//My TreeView is defined to has depth =3 only.
//My code snippet as follows:
// path ="rootNode: parentNode: childNode" // path is something like
this
//try to use the path we already have to judge if a node already
exists in treeveiw

TreeNode rootNode = new TreeNode();
TreeNode parentNode = new TreeNode();
TreeNode childNode = new TreeNode();
for(int depth = 0 ; depth < path.Length -1; depth+
+)
{
string nodeOfTreeView = path[depth]; //to get the
rootNode, if depth ==0
if ( nodeOfTreeView != null) //to prevent some path
only has depth =2 or 1
{
if (depth == 0) //deal with rootNode
{
rootNode.Text = nodeOfTreeView;
rootNode.Value = nodeOfTreeView;
rootNode.Naviga teUrl = @"./
ShowComponentDe tails.aspx?Name =" + nodeOfTreeView;
if
(TreeViewOfPath .FindNode(rootN ode.ValuePath) != null) //is this
corrent??
{
// Indicate that the node was found.
showMsg("The specified node (" +
rootNode.ValueP ath + ") was found.");
}
else
{
// Indicate that the node is not in the
TreeView control.
showMsg("The specified node (" +
nodeOfTreeView + ") is not in this TreeView control.");
showMsg("new rootNode =" +
rootNode.Value) ;

TreeViewOfPath. Nodes.Add(rootN ode);
}
}
else if (depth == 1)
{
parentNode.Text = nodeOfTreeView;
parentNode.Valu e = nodeOfTreeView;
parentNode.Navi gateUrl = @"./
ShowComponentDe tails.aspx?Name =" + parentNode;

if (isNodeExistInT reeView(parentN ode.Text))
{
// Indicate that the node was found.
showMsg("The specified node (" +
parentNode.Valu ePath + ") was found.");
}
else
{
// Indicate that the node is not in the
TreeView control.
showMsg("The specified node (" +
nodeOfTreeView + ") is not in this TreeView control.");
showMsg(" rootNode =" + rootNode.Text);
showMsg("new parentNode =" +
parentNode.Valu e);

rootNode.ChildN odes.Add(parent Node);
}

}
else if(depth == 2)
{
childNode.Text = nodeOfTreeView;
childNode.Value = nodeOfTreeView;
childNode.Navig ateUrl = @"./
ShowComponentDe tails.aspx?Name =" + childNode;
if (isNodeExistInT reeView(childNo de.Text))
{
// Indicate that the node was found.
showMsg("The specified node (" +
childNode.Value Path + ") was found.");
}
else
{
// Indicate that the node is not in the
TreeView control.
showMsg("The specified node (" +
nodeOfTreeView + ") is not in this TreeView control.");
showMsg(" parentNode =" +
parentNode.Text );
showMsg("new childNode =" +
childNode.Text) ;

parentNode.Chil dNodes.Add(chil dNode);
}
}
}
//add the treeview we generated to page's form1

Page.FindContro l("Form1").Cont rols.Add(TreeVi ewOfPath);
}
