FlyGrid.Net trees allow the user to navigate the nodes of a tree by typing the first character of a node's text. However, FlyGrid throws an exception if the traversal crosses a hidden node.

Reproduction:
    Run the VB demo.
    Double-click on TreeView replacement.
    Select Add Root, Add into selected, Hide Selected, Add Root, then Add into selected.
    Select the first node in the tree.
    Type the T key.[/list:u]
    The last step should select the node \"This is a new node\" however, it throws the following exception.

    An unhandled exception of type 'System.ArgumentException' occurred in ninerays.flygrid.dll

    Additional information: The NodeBase specified to FlyGrid.Selected must a valid NodeBase.


    Please fix this soon, as we are using trees with hidden nodes.
