I manage to fill treeview control with data and I would like to search
through that data.

In child I have names of films, and when I click on one of them I would like
to show it's information in grid.
How?

In answer to your first question, you have to iterate your TreeNodes
recursively, such as

private TreeNode SearchNodes(string nodeName)
{
foreach(TreeNode node in myTreeView.Nodes)
{
if (string.Compare(nodeName, nodeText, true) == 0)
{
return node;
}
TreeNode foundNode = null;
foreach(TreeNode childNode in node.Nodes)
{
foundNode = SearchNodes(nodeName);
if (foundNode != null)
{
return foundNode;
}
}
}
return null;
}


As for your second question, just handle the AfterSelect event of your
TreeView and then use the SelectedNode property to determine which node was
selected.
