I have a treeview that is populated. The user will have some node selected in that treeview. A refresh function is called, and the program remembers the full path, so that after the treeview is cleared and repopulated, the same user selected node can be reselected for them automatically.
I have the full path of a tree node. If the full path is "nodea odeb odec" how can I automatically select that node using code?
I'm trying to open a file via a treeview. The nodes resemble the files and folders within a (parent)folder. I also have a textbox which has the location, including the name of the (parent)folder.
msgbox(e.node.fullpath.tostring)
This code gives me the path including the parent-node How do I get the path without the parent?

I'm Trying to select node on treeview with:
Try
Dim nodes As TreeNode() = TreeView1.Nodes.Find("Test", True)
Dim node As TreeNode
For Each node In nodes
TreeView1.Focus()
TreeView1.SelectedNode = node
Next
Catch ex As Exception
MessageBox.Show(ex.Message)

As you can see I'm trying to select the node "test" which is also sub-node. But I get no error nor a selected node.

I tried creating an NDESELECT object to "remember" the node - then tried the old boolean first/loop trick - but it's not remembering that SELECTEDNODE. Seems that the NDE object is just a node object - maybe not "smart" enough to know where it got loaded??

I bring this file into a dataset in visual Studio. The problem ixs that I cannot associate a particular set of options with a particular line item - I can't distinguish Item num="0" from Item num="1" and so forth, because the element 'Item' presents itself as a table withing the dataset, and the element 'Option' also presents itself as a table within the dataset. I don't know how to connect the two.
Why I right click on a node in my treeview the focus moves to this node and then immediately back to the previously selected node. Is there some way that I can allow the right click to select the node?
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 RepliesI would like to select a default node in a treeview(dirDB). That comes from a default drive selected in a combobox(drvDB) that selects files and puts them in a listbox(filDB) i haven't added anything to do that yet. at the moment i have this code:
If optMData.Checked Then
drvDB.SelectedValue() = "M:"
dirDB.SelectedNode.Text = Microsoft.VisualBasic.Left(CStr(drvDB.SelectedItem), 2) & "ase_wdata"
End If
I bet there is a function or a selectNode If kindof thing? i am totally looking over that can choose these. vb seems very good at putting things right infront of me and i just completely miss them..
I want to select a node and make another control visible for that node using an if then statement. From what I read I think I have to put the code in the After_Select method. I gave each node its unique name and unique tag but can't figure out how to address a node name. basically want to click a node and make a panel visible associated with that node. tried something like "If me.treeview1.selectednode.nodePanel1 then pnl1.visible=true" but intelisense doesn't recognize any of the named nodes. can anyone give me some sample code.
View 1 RepliesI want to add nodes that behave in a similar fashion as when you add new folders in windows explorer. i.e. right click > new folder > then the new folder is added and highlighted as New Folder so that as soon as the user types they are overwriting the folder name.
I can add a new node as a child node of the node I have selected and label it "New Node" but I can't figure out how to select the new node and have it highlighted so that when the user types, they are overwriting the "New Node" text.
I have tried this but it doesn't work.

I have a TreeView populated with some nodes, and some of those nodes have children. Is it possible that when the node, or child is selected that the entire node including the children be selected? I still want to deal only with the value of the root node, but for the UI I want the root + children to be selected.

I want to select a node from my tree view, whatever I select is going to get a record from my database, I need a unique ID in each node so it will collect the correct document relating to the selected node.
How can I do this? the name of the node maybe used more than once? Each row in my database has an ID and Title, the title is the name I guess the ID being unique needs to be tied in somehow.
I'm using the following sub routines to allow the user to move treeview nodes up/down:

Nod.Remove()

I want to have a small control follow the selected tree node. However, I cannot find a way to get the location of the selected node (in relation to the tree control itselfI know I could use the mouse pointer location, but I wanted the control to 'snap' to near the selected node by using its exact visible location.

I have been playing with, and researching, this all day and can't figure it out. I have a Windows Explorer style form with a TreeView and a ListView. I've populated the TreeView with directories and when a node is selected, the ListView fills with the contents of the directory associated with that node. No problem there, but I want to be able to select a directory in the ListView and automatically select the associated node in the TreeView, just like it works in Windows Explorer. All the information I've found online tells me how to populate the ListView from the TreeView, but I haven't found any good examples of how to populate the TreeView from the ListView.

View 1 RepliesI have a winform and its fullpath is C: est.exe
How do I get the winform fullpath at run time? For example, the user may move the winform to other places.
I've got a dataset that I maintain. The user interface to the dataset is a treeview and a listbox. The listbox shows the "items" in the treeview node that is currently selected. This works fantastic. As items are added to the dataset, I grab the fullpath property of the treeview node so I can filter and only display items that belong to the in the node that is selected. I then save all of this information to an XML file (including the fullpath of the node that the item is "in").
This all works great and does everything that I want it to. The problem comes when I load the XML file back in. I'm trying to re-create the treeview nodes exactly as they were when the document was saved. I know what the nodes are because of the fullpath property, it looks something like this: State\City\SiteName
I'm trying to create a sub (or function) to recursively create this structure. I've managed to get close, but I haven't actually got the logic yet. I've been able to get all the nodes added, but they seem to only be added at the second level. One thing that I need to worry about is duplicates. In the example above, I might have two sites in the same City. When I got close, I actually had the structure created, but the nodes were getting duplicated. For example: [Code]
ok I have some code below as an example but I can`t seem to sort this one out, I want to pass the fullpath to the directory so that when I click the node it adds the subfolder to that node at runtime Here is my sub below I know why it`s happening but I don`t know how to fix it
