VB.NET treeview error add second child nodes


You seem to get duplicate Keys. Try this:

        If mROC("parentCode").Value =
"" Then
& "A", tmpStr)
            Dim TNode() As TreeNode =
srcTv.Nodes.Find(mROC("parentCode").Value &
"A", True)
            Dim sKey As String =
            If srcTv.Nodes.Find(sKey & "A",
True) Is Nothing Then
                sKey &= "A"
                sKey &= "B"
            End If
            TNode(0).Nodes.Add(sKey, tmpStr)
        End If**

Strange selection behavior of TreeView nodes
Figured this out. TreeView appears to create a TreeViewItem for each node by itself, so when creating your HierarchicalDataTemplate, you do not need to embed TreeViewItem inside it, else WPF will wrap your TreeViewItem inside its own TreeViewItem, thereby confusing the selection mechanism. Simply put a TextBlock (or maybe StackPanel or some other container if you have complex node structure) in yo

How to loop through XML nodes and child nodes using JavaScript?
Attaching the root of your loop on employee rather than name would be better for nested loops (which is what this solution will use): var employees = xmlDoc.getElementsByTagName("employee"); //outputs array of employees for (employeeIndex = 0; employeeIndex < employees.length; employeeIndex++) { var empDetails = employees[employeeIndex].children; //outputs array of details for (deta

rename and send all child nodes based on value of element in child node in xslt
You first need to start off with the XSLT identity template, which on its own copies all the nodes in the XML as-is <xsl:template match="@*|node()"> <xsl:copy> <xsl:apply-templates select="@*|node()"/> </xsl:copy> </xsl:template> This means you only need to write templates for the nodes you wish to transform. You want to change Report_ID elements into R
