View 1 RepliesGiven the xml below why does the first selectsinglenode call not work but the second one does? Are the single quotes specifying a string type or something?

I am trying to identify duplicate serial numbers from the following xml using XPath 1.0 and then evaluating it in .Net using an XPathNavigator.
<?xml version="1.0" encoding="utf-16"?>

I tried to do this by evaluating this
//Items/Item/SerialNumber
expression in a custom XSLT Context Function (implementing IXsltContextFunction like this MSDN example) in .Net but the Invoke function gets called one result at a time so I have no visibility of the other results to find duplicates.
1) Is there a way of doing this using a single XPath 1.0 expression?
2) Is there a way of passing in an array of elements into a single Invoke call of the custom XSLT Context Function class? I'm working in VB.Net but am happy with any C# examples anyone can share.

I need to loop through a gridview to then compare it to my database.this is what i have now:
Dim rows As Integer = gwResults.Rows.Count()
For Each row As GridViewRow In gwResults.Rows
'move through rows and check data in each row against the dataset
cSource.GetDetails(Convert.ToInt32(row.Cells(1).Text))
Next
is it possible to get gridview values in each column by calling them by a name, instead of index? so maybe have something like cells("userID") instead of cells(5)i have many columns, and indexes could get really confusing.

I'm all new to this treeview business. I have a fixed treeview, very simple and basic. Only two levels, parent and child nodes. I just need two things out of this treeview.
1) If parent is checked, check all child nodes.
2) If just one child node is unchecked, uncheck parent node.
That's it! I've been looking for this for 30 mins and I cant find it. Maybe because my vb.net is old, it doesnt seem to be the same as others =/ I'm using vb.net 2003.

I call the sub as follows:
deleteNode(treeview1.Nodes(0).Nodes)

View 2 RepliesI have an XElement and an XPath expression that selects a node from it. It works fine in the original program that I wrote it in but doesnt work if I paste it to another program. I've checked the references and import statements.
