select node in treeview

[Guest]

Hallo!

I'm filling my treenode tv with AD-infos with the following code:
____________________________________________________________________
private enum AdImages
{
AdRoot,
Ou,
Container,
OpenContainer,
Computer,
User,
Group,
Unknown,
Unavailable
}
private DirectoryEntry _AdRootDSE = null;
private DirectoryEntry _AdRoot = null;

try
{
this._AdRootDSE = new DirectoryEntry(@"LDAP://rootDSE");
this._AdRoot = new DirectoryEntry("LDAP://" + (string)

this._AdRootDSE.Properties["defaultNamingContext"].Value);
TreeNode root = new TreeNode((string)this._AdRootDSE.Properties
["defaultNamingContext"].Value,
(int)AdImages.AdRoot,
(int)AdImages.AdRoot);
root.Tag = this._AdRoot;
this.tV.Nodes.Clear();
this.tV.Nodes.Add(root);
this.tV.ExpandAll();
}
catch
{
throw new Exception("Error connecting to AD");
}
____________________________________________________________________

Now I would like to select a single node in the treeview. I've got the info
which one stored in a string like this: "OU=Testunit,DC=Domain,DC=local".
How can I select this one? I've tried a lot of things but nothing works. Can
anyone help me please?

Thanks in advance!!!

Hi Martin,

To select a node in the TreeView, you can use TreeView.SelectedNode
property to set the current selected node in the controls. It must be a
node in the TreeView's Nodes tree.

Please check the following link for more information:

Hallo Kevin,

thanks for your answer. I know this article, but it's no help. There is only
an example for getting the selected node.
But I need help SETTING the selected node. Code like
string val = "OU=Testunit,DC=Domain,DC=local";

this.tV.SelectedNode = val;
can't work, because val is a string not a node and I've got the info of the
node to select only in a string.

What must I change? Or do you know an other example?

Thanks for your reply!!

Hi Martin,

The TreeView doesn't support searching through its nodes. In this case you
have to write a search method, which go through all the nodes in the whole
tree and looks for the matched string. Then pass the TreeNode reference to
the SelectedNode property. HTH.
