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.

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'.

C# - How To Sort Items In ToolStripItemCollection

Feb 24, 2011

I add strings (items) dynamically to a ToolStripItemCollection by:

Dim onClickHandler As System.EventHandler = New System.EventHandler(AddressOf Symbol_Click)
Dim item As New ToolStripMenuItem(newSymbol, Nothing, onClickHandler)
SomeToolStripMenuItem.DropDownItems.Add(item)

So the items are not added in one go, but one-by-one based on external triggers throughout the program session. I would like to sort the drop-down-list every time I add a new item. What are my options to achieve that?

C# - Compare/sort Items From Two Arrays?

Jul 16, 2009

I have a question about efficient implementation. Lets say I have two arrays:

One array is all possible items in a house: Table, Chair, TV, Fireplace, Bed

The other is an array of items in a particular house: Table, TV, Bed

I also have two list boxes:

1. listbox for items in the house - the "HAS" list box
2. listbox items not in the house - the "NEEDS" list box

I need to list the items already in the house in the "HAS" list box as well as the items that are NOT in the house in the "NEEDS" list box. It seems to me that nested "For each" loops would be a start to solving this problem but I am not exactly sure which case needs to be nested.

Sort Listbox With String Items Ascending And Descending?

Nov 24, 2010

How would one code a button so upon cliking it items in listbox would sort either ascending or descending (depends on the button clicked). It mustn't be done with built-in Sort() but with a for loop for example. Tried to pseudo-code the solution to the problem, went as far as "store each listbox item in an array with a for loop".

Array.Sort(array) - Specify A Numeral Sort Based On The First Character In The String?

Jan 29, 2009

Sub Sort()
ReDim RollsCC(NumOfPlayers - 1)

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.
