Visual Basic :: How To Add A Node To Existing Tree View Control

Selective Viewing Of A Tree View Control's Node
hey ppol! need some help here...

i got a tree view. i have the sorted property for each node set to TRUE. and i did not implement the ensuredvisible property so all i got when i start my program is the root value.

here's my problem...

i want to recurse through the nodes of my tree view and print only the VISIBLE nodes...i can print out the values but i can't get it to print in the same order as the tree view...

here's a sample:

ROOT
--CHILD A
----CHILD A1
----CHILD A2
----CHILD A3
--CHILD B
----CHILD B1
----CHILD B2

i want my output to be ROOT, CHILD A, CHILD A1, CHILD A2, CHILD A3, CHILD B, CHILD B1, CHILD B2...but the problem is that it comes out in the order of how i added the nodes...i want it to come out in the SORTED order, line by line, as i see it when i look at the visible nodes of my tree view...

need some help ppol! thx!

Tree View Node Properties
Hey everyone,

I'm wondering if there is an easy way to change the properties of a single node on a treeview. For example, if I have the following data:

Pets
Dogs
Cats
Rats
Rocks

Is there any way I can get Rats to be highlighted in Red, or change the color of the text without affecting all nodes?

Thanks! =)

Tree View Node Properties
Is there a way to dynamically assign a value to a node after it's been created? I need to create a tree view, test it for child nodes, then depending on where the node is, assign an icon to it. Does anyone have any ideas? Thanks, Jeremy

Tree View Node Selection
i have a tree view with an artist node, then when you click that a list of that artists albums shows up and then when you click one of the albums a list of songs come up, how can i know if a song is double clicked??

Tree View Node Bold
is there anyway to force a node of a tree view to be highlighted or bold without clicking on it?

i want the user to viusally see that that node was the last node that was clicked.
the way it is now..the user clicks on the node and once his clicks on something else ..the node loses its bold text

Tree View Node Icons
I am new to tree views and I have created a dynamic tree view. Now, I need to assign icons to them depending on their location and status. (Status meaning if expanded or not) Does anyone know how I can check for child nodes and assign a value to the variable that assigns the icon from a ImageList? Thanks, Jeremy

Right Click On A Tree View Node
I can do the code for a normal click on tree view but what about right click, thanks for any help

Tree View Node Click
I have a tree view with nodes. They could represent anything. I have a excel style control that allows grid like features and functions. When I edit that that grid I need it to click on a node. Please examine the following code.

Code:

Call tvInventoryDD_NodeClick(1)

Syntax in the msdn suggests I would need to use the index #, I was wondering if there was anyway to use the key instead. Also if i need to call this from a different form to provide an updated look what would be the syntax for that?

Tree View Selected Node Before Drag
Hi Team

When I want to drag from a tree view how do I find out which node I started dragging? The SelectedItem does not work as the previously clicked node is the SelectedItem.

Any Ideas, this must be easy!

Thanks

Tree View-node Colour And Multiline

Also is there anyway you can get a node to display multiline text??

thanks

Right Click On A Specific Tree View Node
I am using a TreeView control and I want to use right mouse button to select the nodes of the treeview.

In fact, my objective is to display a pop-up menu if i right click on any node of the Treeview. It does but as you know, mouse down event has only button and x & y co-odrinates as its arguments. So, it never knows if the click is on a specific node or on an empty area.

Now, question is how can we know get the information about the right-clicked node. Also i want to select the specific node if its right-clicked only.

How To Link Data To Each Node In Tree View ?
I need to tie some data (structure) to each node in the Tree view. It can be done in MFC CTreeCtrl using the TV_ITEM's lParam. How is this (Or something similar) done in VB?

Different Context Menus Depending On Selected Node In Tree View
I've managed to get a context menu to appear when I right click anywhere on my tree view control, although I only want it to appear when I right click a node and I also want a different menu to appear depending on the node clicked.

I created a new form and then added a menu called mnuContextMenu and then added the following code to the Mouse Up event for my tree view.

Private Sub Treeview1_MouseUp(Button As Integer, Shift As Integer, x As Single, y As Single)
If Button = vbRightButton Then
PopupMenu Form1.mnuContextMenu
Else
Exit Sub
End If
End Sub

Once I know how to determine which node has been clicked, I shouldn't have a problem changing the menu options for the various different nodes, but I really need to know how to get it to only display the menu if a node is right clicked and also tell me which node is right clicked, which I think involves the Hittest Method.

Any info would be appreciated.

Cheers!

Tree Control Node Names
I am using an InputBox function to prompt for a name for a new node within a tree control at runtime. Is there a way to have an empty box next to the new node in the tree for the user to supply a name, similar to a new folder within Windows Explorer? Thanks

Existing Tree Control Available?
I have to incorporate a tree control just like Windows Explorer, where the tree is assembled at runtime and a list box is on the right side and the input is written to a persist file.

Keep Select Node In Tree Control Highlighted

Tree View Control
I have a combo box that when selected does a case and fills a tree view control. Every time a value is selected in this combo box the tree view gets repopulated with new nodes...
however I need to clear ALL the nodes from the previous selection before adding more.

I tried:

For i = 1 To tvNews.Nodes.Count
tvNews.Nodes.Remove (i)
Next i

But really this is not workign very well...it seems that there should be some CLEAR function or something to clear the treeview nodes. Anyone have any clue?

Its working sometimes and other times its not..so there has to be a better method.

Thanks,
Jon

How do i add things to a tree view control?

Tree View Control
I was just wondering how to determine whether the node that was clicked on in a treeview control was a parent or a child. I have tried the following:

If TreeView1.SelectedItem.Parent = True then
Msgbox "Parent"
Else
Msgbox "Child"
End If

This code does not work. Does anyone have some code that can determine whether the selected node is a child or parent?

Need Help With Tree View Control
I need some help with the Tree View control. I set the properties so that the nodes have check boxes next to them.

When the parent node is checked, I want all the child nodes of that parent to be checked. Same with unchecking them. I won't know for sure how many child nodes there are. How do I do this in code, and do I do it in the NodeCheck event?

Some sample code would be a great help. Thanks.

I am having problems with adding nodes to a tree view control

I specify a key for a child node with a string variable, and it returns an error,
# 35602, "Key is not unique in collection". The string I use is not the same as the text or any other strings to do with that node. I cannot figure out what I am doing wrong here.

Can somebody help me?

Tree View Control
Hi all!

I use the VB tree control within Visual Basic to display a hierarchical structure. When the hierarchy gets deeper and the expanded hierarchical structure is displayed the behavior of the enabled scoll bars results in positioning the scroll bar at the rightmost edge. As a negative consequence of this behavior the root element disappears.
Does anyone know how to avoid this scroll bar behavior ?

Thank you in advance for recommendations!

Best regards!

Tree View Control
Hi all!

I've a beginners question concerning the scrolling behaviour of the Tree View Control. When the displayed tree hierarchy is quite deep and the width of the control isn't sufficient to display the complete hierarchy, the enabled horizontal scroll bar automatically is scrolled to the right edge in order to display the leafs of the tree. BUT unfortunately, I'd prefer to have the scroll bar at the left edge in order to see the root. How can I influence the control to behave this way?

I'm grateful for any recommendations! Thank you in advance!
