path navigation

hi there.

i basically have a program which displays lists of files in one filelist box, and can navigate using the treenode/view box.

i have a text box where the user can type in the path to navigate to.

if the user enters the incorrect path, a message appears (exception) which i have caught.

however

if the user types in an invalid path BUT then without clicking the "navigate" button, they click on a node in the treeview, the program generates an exception (Visual Studio.net)

because it is adding the path with whatever is in the textbox + the current treenode it is on, therefore the error is thrown at me

how can i sort this? I want it so that if the invalid path has been entered then user clicks on a node in the treeview, i want to get the path of that treenode they selected and put that in the textbox

thanks!

check before adding a directory to the listview that it actually exists with the System.IO.Directory.Exists() method, and show a message box then.

Unless I'm missing something :)
