Asp.net - Find TreeView Node By Value?

Sep 15, 2011

All 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?

Bottom Node In TreeView Is Cut Off

Jul 9, 2010

I have a TreeView in my form that I populate manually from a list of items in a database. The descriptions of the TreeView items causes a horizontal scrollbar to be displayed. That is fine except that it seems that this scrollbar hides the item at the bottom of the TreeView. If I expand a tree node the bottom item that was previously hidden will be displayed.

How To Sort TreeView Node

Mar 29, 2012

I 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'.

VS 2005 Add A Node To Treeview?

Mar 23, 2010

I 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.

.net - TreeView Root Node Selected?

I have this code to select first node of TreeView. But when page loads the by default root node is other than first, I want to set the selected node as top most by default. Here is my code in page load but it's not working:

Dim nodes As TreeNodeCollection = TreeView1.Nodes
If nodes.Count > 0 Then
' Select the root node
TreeView1.SelectedNode = nodes(0)
End If

This gives the blue underline error on this line:TreeView1.SelectedNode = nodes(0)

The error is: "Selected Node Property is read Only"

ASP.Net Treeview Truncates Node Text

Nov 15, 2011

I have a treeview on my ASP.Net page and for some reason the text on some nodes gets cut off, I am programatically adding all the nodes and am aware of the existing issue listed here: [URL] however I am not changing the font and as you see in the code below this fix does not work for me.

Private Sub populateTreeView()
'Code that gets the data is here
Dim ParentIds As List(Of Integer) = New List(Of Integer)

[Code]....

The strange thing is that this issue only appears in IE, I have tested it in chrome and Firefox and both browsers display the text perfectly.

When I select a node this fixes the problem and all text displays as normal.
