[2005] Prevent TreeNode From Collapsing When DoubleClicked?
Feb 16, 2009
I have got a standard Windows Forms Treeview which contains some nodes.I am using NodeMouseDoubleClick event to get the node and then get the ID of the node and show a form containing data that belongs to the ID.What I am stuck at is when I double click any node, it Collapses or Expands depending on it's previous state. I want to Prevent TreeNode from Collapsing or Expanding when DoubleClicked but allow when user clicks that tiny "+" or "-" button in front of the node.

In Visual Studio C# (2008) ctl-M-L expand all the regions. There's also a setting in Text Editor->C# ->Advanced to not collapse during file open. I see no equivalents in VB.NET.Is there a way to expand all the regions, not just the one which has focus in VB.NET.

I have a sulution consisting of aout 30 projects, where 8 of tehm are deployment projects. Currently, when I want to debug the winforms app, I press "start debugging", and wait for about 15 minutes for the solution to be built, and also the deployment projects to be built and packed. The solution itself is built in about 2 minutes, the rest of the time is for the deployment projects.So, my question, is there a way to make the setup in visual studio so that only the code projects are built and the deployment projects to be built manually when needed?

I'm having a problem with my listbox control. I am trying to handle all the keypress events for the listbox and changing the index to the item I want as they type. But the problem is the listbox changes the index to the last key they hit. Here is what's going on.

I have created a series of custom user controls for a wizard interface that I am making. Each user control represents one step in the wizard and really shouldn't be used outside of the wizard. The thing that is bugging me is that each wizard step user control shows up in the toolbox of components to insert into a form.
Is it possible to hide a user control from the toolbox? Better yet is it possible to hide a user control from other classes not in the same namespace of an assembly? Is this a good approach or should I think of a different approach?

I'm writing a bit of code that I want to populate a TreeView, which it does quite successfully, but I also want to put a Dictionary in the Tag of each Level 1 child node. Once the Tag has been set to the Dictionary, is there any way I can modify the dictionary, without redeclaring the Tag.For Each verse In Verses
Dim _verse = verse.ToString.Trim
Dim _node As TreeNode = New TreeNode(_verse.Split(vbNewLine).First & "...")
_node.ToolTipText = _verse[code]...

I need to grab the TreeNode that's selected when someone right-clicks on it. The TreeView.selectedNode() returns the top-most node, and disregards the child nodes.

I have some code that allows me to drag a treenode into a listbox and then drag it back into the treeview as needed. When I drag a node out of the treeview, the node is removed from the treeview. When I drag it back, I need the node to be inserted into the same parent node/position it came from. I think I can save the node's FullPath property before removing it from the tree, then decipher it again when I re-add it but am looking for a cleaner way

It seems that Visual Studio is using a older verion of the System.Windows.Forms DLL.
When I instantiate a instance of the TreeNode object it doesn't have the "value" property. Right now my version of Sytem.Windows.Forms is listed as 2.0.0.0 and it's being pulled from the Microsoft.NETFrameworkv2.0.50727 folder.
I've installed all of the current .NET framework service packs....
Is there something else that I need to do so that the I load the most current version of this object?
