InfoPath Dev

Hi,

how do I get the selecetd value of a dropdown list? This

string id = thisXDocument.DOM.selectSingleNode("/my:training_administration/my:courses/my:course/my:id").text;

only returns this error:

System.NullReferenceException
Object reference not set to an instance of an object.
at WBTAnmeldung.WBTAnmeldung.btnViewDetails_OnClick(DocActionEvent e) in d:\vs2003\projects\wbtanmeldung\formcode.cs:line 39
at Microsoft.Office.Interop.InfoPath.SemiTrust._ButtonEventSink_SinkHelper.OnClick(DocActionEvent pEvent)


Any hints?

Thanks in advance.

I hope this will work for you,

Hi,

thanks for the hint, but in this case I don't have to deal with SharePoint. I just want to get the selected value from a dropdown list within an InfoPath form. And there I receive this System.NullReferenceException when I want to retrieve the value.
I guess this can't be hard to accomplish, but at the moment I'm a bit stuck.

Hi Buki,
thisXDocument.DOM.selectSingleNode("/my:training_administration/my:courses/my:course/my:id")
is not returning the node. Probably your XPath might be wrong. One thing you need to note here is XPath is case sensitive.

Hi,

you're right :) I missed a slash.
thisXDocument.DOM.selectSingleNode("//my:training_administration/my:courses/my:course/my:id").text
I'm so blind :) Sorry for bothering.
