Re: Finding view and setting focus

Thanks Matt. Still not working for me.

I'm not quite sure what XDocument.View.GetContextNodes() is supposed to be returning. I was hoping that it was the subset of data nodes bound to the View...but it doesn't seem to be.

I designed a new blank InfoPath form with two simple text nodes:

Data Source
myFields
field1
field2

I then put one field (field1) onto the view along with a single button. Clicking on the button invokes XDocument.View.GetContextNodes() and displays the nodes and one level below (their children):


function Button::OnClick(eventObj)
{
  // fetch View's ContextNodes...whatever that means :o)
  var objXMLNodes = XDocument.View.GetContextNodes();

  for (var i = 0; i < objXMLNodes.Count; i++)
  {
    // fetch current node and its children
    var objNode = objXMLNodes.item(i);
    var objChildren = objNode.childNodes;

    // display current node's name
    XDocument.UI.Alert(objNode.nodeName);

    // display name of each child node
    for (var j = 0; j < objChildren.length; j++)
    {
      XDocument.UI.Alert(objChildren.item(j).nodeName);
    }
  }
}

XDocument.View.GetContextNodes() returns one node: "my:myFields". As it loops through the children of this node, it displays both "my:field1" and "my:field2", even though only the first of these is in the active view.

Does anybody know how to enumerate the nodes bound to a View? Or enumerate the controls in a view and find the bound data node for each control?

Try this:

var nodelist = XDocument.View.GetContextNodes();

var present = false;

while( n = nodelist.nextNode() )
{
	if( n == selectSingleNode("xpath/to/node") )
	{
		present = true;
		break;
	}
}

if( present )
	XDocument.View.SelectText(objNode);

Finding view and setting focus

4spammers — Thu, 13 Oct 2005 15:15:34 GMT

I am working with an InfoPath form with multiple views and submitting via HTTP POST to a Java servlet. If I get an error message back from the servlet (e.g., the value for "/xpath/to/node" needs attention), I would like to not only display a message (I've done that), but also set focus to a field bound to that node.

I can use View.SelectText() to set focus, but how can I tell which view(s) have a control bound to the node? Can this be answered using JScript?

Here's some pseudocode to describe my question...


// assume we're given XPath to a node with a "problem"
var problemNodeXPath = "/xpath/to/node";

// Fetch the specific DOM node using XPath
var objNode = XDocument.DOM.selectSingleNode(problemNodeXPath);

// Get the views that contain 1+ controls bound to the node
// Can this be done using JScript?
var possibleViews = viewsWithControlsBoundToNode(objNode);

// Switch to the first view that uses the data
XDocument.View.SwitchView(possibleViews(0))

// Set focus to the "problem" node
XDocument.View.SelectText(objNode);

In the fictitious viewsWithControlsBoundToNode(node) method above, I would iterate through available views, test each one to see if it contained a control bound to the given node, and return a list of those views that met the criteria. Even an anyViewWithControlBoundToNode(node) method would suffice.

My apologies if this has been covered or answered elsewhere. Any help would be appreciated.
