Re: identify row in a Repeating Table

Thanks MFaus, but i have the same problem.
with
var idx = eventObj.Parent.selectSingleNode("@idavance");
XDocument.UI.Alert(idx.text);--> Error:Object required.

Why idx is null?

Thanks for the link to learn XPath, i take the course.

Yes, you can do this.

Your source might need to be "normalized" so try this line instead:

var idx = eventObj.Parent.selectSingleNode( "@idavance" );

The error that you listed - null or not an object - is almost always because your XPath is wrong. Check out this tutorial for a helpful start: http://www.w3schools.com/xpath/default.asp

i try this too:
var strUserName = eventObj.Source.selectSingleNode("@idavance").text);

IP, send me : Source.selectSingleNode(...)' is null or not is a object.

Is there a way to extract a piece of data in a field on the line that currently has the focus and then do a comparison with that single data point?

MFaus i try this:

var idx = eventObj.Source.parentNode.selectSingleNode("@idavance");
XDocument.UI.Alert(idx.text);

But in second line jscript send me error.

How i can do a data reference to specific cell on repeating table?

Fred,

Try something a little more like this:

var idx = eventObj.Source.parentNode.selectSingleNode( "@idavance" );

You can use the eventObj to do relative selecting of XML. I hope this helps, let us know how if you have any more questions. Also, if you search around on this forum you might find several code examples to help you out a little more.

How i could take a value from a field of a repeating table before i delete that row.

I do this, but ip send me a error.

function msoxd__Avances::OnBeforeChange(eventObj)
{
if (eventObj.Operation=="Delete" && oNode=="Compromisos")
{
var idx=eventObj.Source.selectSingleNode
("/dfs:myFields/dfs:dataFields/.../idavance");
XDocument.UI.Alert(idx.text); --->('error here!!')
}
}
