InfoPath Dev

I'm used to visual basic and not VSTA, but ive been trying to use this code to clear some text boxes when a user hits submit.

Dim root As XPathNavigator = MainDataSource.CreateNavigator()
Dim textbox As String = root.SelectSingleNode("my:myFields/my:textbox", NamespaceManager).Value
with me
textbox = ""
end with

usually in visual basic i can say textbox.clear() but that does not work in VSTA, also the code i posted does not clear it either. any ideas?

Hi--

Infopath doesn't provide programatic access to the form controls, only the data. Not sure what your data field is named, but if it really is named 'textbox', and assuming that you are using VB.NET and InfoPath 2007 (since you specifiy VSTA) you'd want to use something like:

Dim root As XPathNavigator = MainDataSource.CreateNavigator()           
Dim textbox As XPathNavigator = root.SelectSingleNode("/my:myFields/my:textbox", NamespaceManager) 

textbox.SetValue("")

Hi Hilary,

thanks for your super-fast response. unfortunetly when i use your code, debugger gives me the following error.

{"Operation is not valid due to the current position of the navigator."}

any clue what that means?

Thanks!

Interesting. It works in my sample form. What event are you using the code in? Is the name of your field that you are trying to set to blank really 'my:textbox'?

 The only way I can seem to reproduce that particular error is if I do SetValue("") directly on root (i.e. the object returned from MainDataSource.CreateNavigator() ).  Did you use Hilary's code exactly the way it is or did you modify it somehow?

oh i figured it out, my code was not exactly the same as hillary's. dumb mistake actually, the code worked perfectly, thanks!
