View 2 RepliesI have been working with VB 6.0 for years. I am converting an app that uses treeviews to VB.Net 2008. The way it use to work the tree grid started with a list of the drives on the system. Left click drilled down in the selected drive or directory. Right click would perform an action with the selected drive or directory. In VB.Net it appears you can only select with left click using the AFTERSELECT event. Is there a way to select a node with right click?
View 1 Repliesfor some reason I have to click a node in a treeview twice for it to register as selected. I've checked with treenode.isselected() and treeview.selectednode() and with both two clicks is required to show the selected node (1 click continues showing the previously selected node as selected) while the visual highlight/selection works perfectly with 1 click. Any suggestions on what may be wrong/how it could be fixed? (The node selection code is in the nodeclick event)

View 9 RepliesI have two custom action listers. One that handles Mouse.Click and one that handles Mouse.MouseDown. My question to you is, can I delay the mouse down event so that it does not intefere with the code of the Mouse.Click event? I have tried adding a timer and waiting x amount then setting a bool value to true, but the code executes to fast and it skips the other code.

View 6 RepliesAll 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?
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.

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)

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'.
