I don't think using Console.WriteLine() and Console.ReadLine() is going to do much. There is no console in an InfoPath form.

it must be mainDataNavigator.SelectSingleNode("/my:myFields/my:bericht", NamespaceManager).Value)

you placed /my:Fields in place of /my:myFields..check out

for the moment, something as simple as

public void CTRL50_5_Clicked(object sender, ClickedEventArgs e)

{

XPathNavigator mainDataSource = MainDataSource.CreateNavigator();

Console.WriteLine(mainDataSource.SelectSingleNode("/my:Fields/my:bericht", NamespaceManager).Value); Console.ReadLine();

}

is giving us a NullReferenceException.

If you post the code you're trying to use, we might be able to figure out what's going wrong.

Ok, will try that again then! :)

But the problem was that when we did that we got "KeyNotFoundException".

In InfoPath we don't access a form's controls directly, but by accessing the XML document represented by the main data source. An InfoPath form is just a visual representation of an XML document. So if I had a textbox bound to a field with the path myFields/field1, I could change its value like this:

XPathNavigator mainDataNavigator = MainDataSource.CreateNavigator();
mainDataNavigator.SelectSingleNode("/my:myFields/my:field1", NamespaceManager).Value = "Hey!";

If you are not yet familiar with the XPathNavigator class, I recommend reading up on it a bit.

Accessing controls in C#

yoni_R — Fri, 20 Feb 2009 10:13:11 GMT

Hi,

we're trying to make a form (not browser enabled as we are using an mutiple selection listbox) that will enable us to choose a bunch of members. Those members need to receive an email after the send-button is pressed.

The problem we have is that we can't find a way to access the content of the controls in de form in our code in C#.

Can anyone tell us what we can do to make this happen?

thx
