Locate the node using the control's Nodes property. Then set the control's SelectedNode property. /ravi

How to use this exactly?

Iterate through the Nodes collection; check each TreeNode to see if it matches your criteria. If it does, set the control's SelectedNode property. /ravi

This example assumes that the node's Tag property contains the data (like a key value) that you're looking for:

public TreeNode GetTreeNode(string sNodeTag)
{
TreeNode oRetVal = null;

foreach (TreeNode oNode in treeView1.Nodes)
{
	if ((string)oNode.Tag == sNodeTag)
	{
		oRetVal = oNode;
		break;
	}
}

return oRetVal;

}

Everything makes sense in someone's mind

When you say "set a specified node in treeview", I'm guess you're talking about setting the SelectedNode. Again, this code assumes that you have stored a distinct value to each node's Tag property, and are passing that value into this method.

public void SetActiveNode(string sNodeTag)
{
foreach (TreeNode oNode in treeView1.Nodes)
{
if ((string)oNode.Tag == sNodeTag)
{
SelectedNode = oNode;
break;
}
}
}
