Yea that's the case, just wasn't familiar with the previous-sibling subpath, or XPaths in general. Do you have to use the whole XPath location of the node with preceding-sibling? Or just its immediate group?

The my:group2 part is not generic, but in almost all cases, there is only one repeating node in a given repeating section. Is that not the case in your form?

So it is. Found info here: http://www.infopathdev.com/blogs/greg/archive/2005/06/13/Using-XPath_2700_s-_2700_preceding_2D00_sibling_2700_-Axis-Correctly.aspx

Thanks for yalls help.

Or is preceding-sibling actually some sort of keyword?

But is this solution generic?

It looks like you are selecting the previous node based on it's name? I don't have a set name for each node nor a set number of nodes. The nodes that I need to be able to move up/down are in a repeating section which the user adds however many nodes he needs.

As Hilary already said, the current node can be accessed by e.Source. Here's code for moving an element up within its section. I'll let you figure out the down version:

        public void CTRL5_5_Clicked(object sender, ClickedEventArgs e)
        {
            XPathNavigator currentNode = e.Source;

            XPathNavigator prevSibling = currentNode.SelectSingleNode("preceding-sibling::my:group2[1]", NamespaceManager);

            if (prevSibling != null)
            {
                prevSibling.InsertBefore(currentNode);
                // The line above creates a copy, so delete the original
                currentNode.DeleteSelf();
            }
        }

I have been through the documentation there. Is this problem even feasible, because I still cannot figure out how to access the node itself in order to move it to a different location.

Thanks.

Hi -- ClickedEventArgs e is one of the parameters for the clicked event. e.Source gets you the group that the button is in....this documentation from MSDN will give you some additional information.

This is a pretty simple problem right? Just how do you access a current node when all you are given to work with is an XPathNavigator?

Button click Move up/Move down in C#

Hi all. I am trying to do a basic button functionality thing where you are able to move nodes up or down, in a repeating section or table. Now I know there is some VBScript at http://blogs.msdn.com/infopath/archive/2005/02/23/378968.aspx. This should be simple to port over to C# (which I need to do) but there are some nuances I can't figure out. How do I select the current node with the C# version? In VBScript you can just set currentNode = eventObj.source, but in C# the argument variable e is of type XPathNavigator. Can someone please point me in the right direction. I have played around with all the functionality in an XPathNavigator object and cannot get it to return the current node in any way. I might be going about this completely wrong.

Thanks for the help. Below is my code.

        public void CTRL27_11_Clicked(object sender, ClickedEventArgs e)
        {
            XmlNode currentNode, parentNode, prevNode;

            currentNode = /* what goes here? */
            parentNode = currentNode.ParentNode;
            prevNode = currentNode.PreviousSibling;

            if (prevNode != null)
            {
                parentNode.RemoveChild(currentNode);
                parentNode.InsertBefore(currentNode, prevNode);
            }


        }

        public void CTRL28_11_Clicked(object sender, ClickedEventArgs e)
        {
            XmlNode currentNode, parentNode, nextNode;

            currentNode = /* what goes here? */
            parentNode = currentNode.ParentNode;
            nextNode = currentNode.NextSibling;

            if (nextNode != null)
            {
                parentNode.RemoveChild(nextNode);
                parentNode.InsertBefore(nextNode, currentNode);
            }

        }

I just don't see how you are able to move the nodes around in Clicked( ) in C#, when all you are passed is an XPathNavigator. All of the XPathNavigator methods are for moving itself to other nodes. What I want to do is actually move the nodes themselves.

Thanks again.
