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'.

Sort Items For A TreeView?

Sep 28, 2010

I am trying to sort a treeview, base nodes, which is the first base set you see before you click any + sign's I am trying to sort by alphabetical order, but, for the nodes inside each + view of the tree's I want to sort by number order, the number is currently set to the tag as text version of the number. Anyways, for the nodes in the + view's I need it to be able to skip over numbers if not every number in sequential order is there, so if number 4 is missing for example, still sort 1,2,3,5,6. My full code is pretty big but just retrieving items to display is random & I just add items as they come in, now they don't come fast or even when your not expecting new things to appear so it should not matter how it works really as it wont be updating as they are using the treeview.

Jan 29, 2009

Sub Sort()
ReDim RollsCC(NumOfPlayers - 1)
For N As Integer = 0 To (NumOfPlayers - 1)[code]....

Here I am creating a temp single dimensional array, merging my 2d array into it, and then attempting to sort it by Rolls(N,1), which is a integer 1-6, Everything seems to be working right with the exception of this.

RollsCC.Sort(RollsCC, 0, 1)

How would one specify a numeral sort based on the first character in the string? im aware that I am switching Rolls(n,1) and Rolls(n,0) information during the sort.

Populating A TreeView From A TreeView Instance

Sep 13, 2010

I have a class, let's call MyClass. In this class, I have a TreeView property let's call myTreeView..In my code, I populate the Nodes of this TreeView so I can use it later on.Then, when it's time to actualy use it, I haven't been able to take all the nodes from myClass and put them in a Tree View Control on my form.[code]The weird thing is that when debugging, the TreeView in MyClass is well populated with the proper values and in the loop, newNode isn't empty, there's actually something but for some reason it's not showing anything.

Expander Of Some Sort?

May 15, 2010

I know there is an expander for WPF applications, but I have a WFA (Windows Form App) and I can't make it a WPF because of the progress I've made on it, and I just don't like WPF. But I need the expander, or an alternative to it, on my WFA. I can't reach the namespace for wPF from WFA either, so I can't create one. And selecting one in the controls list won't make it show up. know of a expander, or alterative to hiding things like that?

How To Sort An ObservableCollection

Jul 8, 2009

I have a WPF app which binds a System.Collections.ObjectModel.ObservableCollection to a listbox. This ObservableCollection contains instances of my own class (named DataContractsUserObject) and at runtime when I add an object to this collection it automatically appears in the listbox because of the binding. The problem is that it always appears at the bottom of the list and I would like it to appear alphabetically sorted as the existing items in the listbox are.So I tried to sort the collection by doing this after I add an item to it:[code]but of course that is not actually sorting the original collection is it, its just sorting a new instance that is in a Generic.List format. Whilst I probably could just do that and then set that new list instance back as the source of the listbox binding, that will cause all of the items to be reloaded (and when each item in the listbox is loaded it animates in, so it would look stupid having all items animate in again just because one has been added).

The ObservableCollection class itself does not have a Sort method and although I know how to implement my own comparison class (using IComparer) I dont know how to make this work on an ObservableCollection without doign ToList or ToArray etc.[code]Just found this that looks like it might be of some use url...

How To Stable Sort Using A Key

Nov 23, 2008

I was wondering if anybody knew how to stable sort an array in VB.NET using a key.Basically, I am reading 2 CSV files and populating 2 arrays in parallel. The first array (asLines) holds the entire lines read from both files, and the second array (aiTrans) holds only the transaction #'s from those lines (the 2nd field of the line).What I want to then do, is stable sort asLines using aiTrans as the key.url...How can I sort asLines using aiTrans as the key and keep the order?

Sort A Dictionary By Value?

Dec 1, 2011

i was searching for a simple solution that i can use in sorting a dictionary by value, and i was not content with what i found, so i made up these two functions for sorting a dictionary ascending and descending. I do not assume that they are perfect, so improvements are welcomed. They are written in VB.Net and use an intermediary dictionary.

Public Function SortDictionaryAsc(ByVal dict As Dictionary(Of Long, Decimal)) As Dictionary(Of Long, Decimal)
Dim final As New Dictionary(Of Long, Decimal)

.net - DataGridView Sort Does Not Work

Nov 9, 2010

Visual Studio 2010 VB.NET

I have a DataGridView.DataSource set to a Collection of custom objects. The columns use read only properties from the custom object for display, this dialog is for display only. The properties all return String objects. I set the columns all but 2 of them to sortmode automatic (the ones that are not set is a button or a checkbox). Yet it does not sort. I have googled around and most people use sql or binding sources but I am using a trivial vb collection. Some say I should implement IComparable but isn't String already IComparable?

Per a request here are some code snippets.

This method defines the columns in detail from columns I designed in the designer.

The column names are called pSelected or pCustomer and corresponds with a property by the same name that the column definition ties to.

Protected Sub UpdateDGVUS()
If Not USColumnsInitted Then
USColumnsInitted = True
