I'm facing a problem with Treeview, I'm using it as a menu in a app, but I just can't find anything related on how to change the hottracking event, like the font color, or the background color once an item is selected.
View 7 RepliesI have a simple TreeView with HotTracking Property set to True. It works when I move the mouse over an item. But it doesn't work when I use Drag&Drop and Drag something over a TreeView Item. Is there a way to use the HotTracking with DragDrop? Or any workarounds?

View 4 RepliesI have an explorer-like form with a TreeView and a ListView. I have finally figured out how to populate the the ListView based on the selected node, but when I am debugging, I click on a node, and the ListView doesn't change. I have to single click twice on the node for it to work. What could be my issue? I have included the code from my sub below.
Private Sub TreeView1_NodeMouseClick(ByVal sender As Object, ByVal e As System.Windows.Forms.TreeNodeMouseClickEventArgs) Handles TreeView1.NodeMouseClick
Dim newSelected As TreeNode = e.Node
ListView1.Items.Clear()
Dim subItems() As ListViewItem.ListViewSubItem

I'm looking to populate a treeview control with nodes, at RUNTIME. When the user clicks on the node, it will open up a form to display the data for the device represented by the node.There are three groups of nodes. Each group has its own form that it uses. For example:
-Root
---Group 1
------Device 1

I'm having a problem with the treeview I cant find a way to find the click event in each child nodes Here's a sample image here's what Ive tried so far.
[Code]...
i do have a treeview with it's property "DrawMode" set to "OwnerDrawText" because sometimes the display nodetext has to appear in bold format. Generally, thinks work fine, but after refreshing the treeview, the nodetext appears twice! Not only does it appear where the nodes are, but also on the upper left of the treeview control. Before reloading the nodes into the treeview, I use the treeview.clear-method to get rid of the old nodes in the treeview.
Here is the code of the drawNode-Event:

View 4 RepliesI have a tree view with checkboxes. When a user checks an item in the tree, all items below it in the tree should be checked automatically to match the parent. The same is true is a user unchecks an item. That's been reasonably easy to implement using the after check event:-

How can I work on a treeview to preform a task on the event that a node it clicked?
View 8 RepliesI have a custom contro which inherits directly from Treeview. Is there any way to handle some event related to when the TreeView Scrollbar appears (it does this when the height of the stack of visible nodes exceeds the height of the control) or "disappears"?
I realize if could set up a function which checks the ItemHeight * Nodes.Count, and compares this to the control height. However, this seems clumsy. I have been exploring the object browser (and anylized TreeView with Reflector) and have not found what I am looking for. If there is a way to access the ScrollBar Property at ALL within TreeView, I have not found it.
i have a treeviev and listbox.i want to display the selected contents of treeview into the listbox.my code is working for file but not for folder. means i want, if the all contents of folder ABC(i.e all files) are selected then in listbox i want to show the only path of folder not the seperate path of each file.

View 3 RepliesI want more customization then the original VS 2010 set up files. So i decided to code everything. For example, i put all my files in my debug folder into my installer.vb's My.Resources. So i usedSystem.IO.File.WriteAllText ---> to install all my files and the .exe one.Everything was installed it except my Ethup Bolt New Build.exe. It shows up in the folder after installation, but when i click on it, it didnt run at all. (It showed up in the task manger, under process, but it disappeared after like 5secs.) So it didnt
run at all. My question is how do i install my .exe properly. ( I DONT WANT TO USE THE ORIGINAL INSTALLER WITH Visual Studio)

I've done a lot of work to customize the template for ContextMenu in my app, and it worked great as a "right-click" popup window.To my enormous surprise, when I wanted to add the same ContextMenu to a button to work as a kind of "drop-down" menu, it reverted back to the default template. It is really, really, weird, considering it's the exact same control I'm using, and when I right-click the button the template is the one I customized, but when I left-click it(and open it with ContextMenu.IsOpen = True) it uses the default template? I'm pretty baffled right now, and hope that this isn't one of the (many) quirks with WPF that will require me to write hundreds of lines of XML code to fix something that shouldn't even be an issue in the first place.

View 9 Repliesis it possible to customize the properties of a form? for instance, i would like to start a new project, and have my form load center screen, not windows default location from the startup location, among many other options.if this is a possibility, from within vb.net, which i was not able to find and customize, do advise on how to do so.if i have to hack vb.net, i would not know where to start to do so, but how would i begin? what file do i need to modify in the program files folder of vb.net? this, by any means, i would not find it as a hack to destroy someone's work, but to better the software for the user.if a moderator reads this post , do consider my concern for customizing vb.net as vb.net customizes for the users..what i mean, is that, if this option is not available, mods, look into providing an update for vb.net to allow the customizing of the properties for forms/toolbox items and do reply to this thread w/a link.
unless vb 2o10 provides this option, which i doubt, and if it does and there are skins for vb.net 2o1o to change the tab look to the 2oo8 vb.net look, do not advise to look toward the 2o1o version.. personally, the 2o1o tabs are ridiculous, the font in the code window could have been the same as vb.net 2oo8 also.
