.net - Calling A Method When A Tree Node Is Clicked In The Standard ASP.NET 2.0 TreeView?
Apr 17, 2009I have a treeview which i populate dynamically using an XML Datasource. The leaf nodes in the TreeView attempt to open a URL in an iframe within the page.This all works fine, but i would like the iframe to be hidden until the point the leaf node is selected.what event is triggered when the nodes are clicked?? I tried the SelectedNodeChanged event but this doesnt seem to get triggered!
UPDATE - The TreeView code is shown Below
<asp:TreeView ID="TreeView1" runat="server" OnSelectedNodeChanged="TreeView1_SelectedNodeChanged" DataSourceID="XmlDataSource2" AutoGenerateDataBindings="False">
<DataBindings>
[code]....
While fiddling with my code i noticed that when i remove the NavigateUrlField="URL" from my code the tree triggers the SelectedNodeChange event, But does not Trigger if NavigateUrlField="URL" is put back in.

View 6 RepliesAsp.net - Find TreeView Node By Value?
Sep 15, 2011All my TreeView nodes have a unique ID for their Node Depth.
I want to set Checked=True on the TreeView Node which matches a certain value.
Currently I'm doing the following:Dim value As Integer = 57
For Each n As TreeNode In tvForces.Nodes
If n.Value = value Then n.Checked = True
Next
Is there a better way of finding the Node which I want to set as Checked=True rather than looping through each node?
I'm looking for something like:Dim value As Integer = 57
n.FindNodesByValue(value)(0).Checked = True
Is there anything like this that I can use?

How To Sort TreeView Node
Mar 29, 2012I have a treeview in my program that lists all the folders and files in my TV Video collection. The tree lists as follows:
TV Series
|___SeriesName
|___SeasonNumber
|___EpisodeName
The problem I am having is that the SeasonNumber node does not sort 'properly' as I would like it.
It sorts like:
Season1
Season10
Season2 etc.
Instead of:
Season1
Season2...
Season9
Season10 etc.
I have tried this:
Private Sub scanFilesList()
Dim sfilenames() As String = System.IO.Directory.GetFiles(folderPath)
For Each strFileName As String In sfilenames
strFileName = GetFileName(strFileName)
tvVideoList.Nodes(n).Nodes.Add(vGroup, strFileName, 2, 2)
[Code] .....
As I understand it, this is supposed to sort ascending but it doesn't seem to change anything. I really only need to get the grandchild node sorted 'properly'.

View 2 RepliesVS 2005 Add A Node To Treeview?
Mar 23, 2010I can't work out how to add nodes to a treeview as a child of a particular identified node.
The treeview.nodes.add function has seven overloaded definitions each of which seem to add it as a child of the root node. I can't find a way to specify the parent.
I've found this article which gives an example
TreeView1.Nodes.Add , , "root", "Root Item"
TreeView1.Nodes.Add "root", tvwChild, "child1_root", "Child1 of Root"
TreeView1.Nodes.Add "root", tvwChild, "child2_root", "Child2 of Root"
TreeView1.Nodes.Add "child1_root", tvwChild, "child1_child1", "Child1 of
Child1"
I've seen several similar articles with the same format. However this doesn't work. I get compilation errors. It doesn't match any of the function definitions, and tvwChild is not recognised as a constant.
