Make parent node visible in treeview 1

[shaunhubbs]

Hi all,

I was wondering if anyone knew how to make the parent node visible after deleting a child node from a treeview. I know how to get the parent information -- whether it be the index, key or actual description, but I can't figure out from there what I should use to display the node.

The steps I used were:
1) User selects an item (node) in the treeview
2) They click a 'Delete' button which then triggers a stored procedure to delete the item from my SQL database
3) I reload the tree
4) This is where I want to reopen to the parent node. -OR- If it is easier just delete the item I just removed from the SQL database from the tree and leave the tree just the way it is eliminating the reload in Step 3.

Thanks in advance for any help.

I think you're trying to expand the original parent node. If so, try setting the Expanded property for that particular node since you already know how to get to it.

That's where I am having the slight problem Max...the syntax...

I have a variable called 'DeletedParent'. Should I set it equal to the index, key or description?

From there what is the syntax for getting it to be 'expanded'. Is it axTreeview.Node(DeletedParent).expanded = true or something else?

Thanks again.

Set it to the index, and then axTreeview.Node(DeletedParent).expanded = true should work just fine.

Here is what I have:

    Dim DeletedParent As Integer
    DeletedParent = axTreeView.SelectedItem.Parent.Index
...
     axTreeView.Node(DeletedParent).Expanded = True

And now I am getting:

'Object doesn't support this property or method.

I'm not sure why it would do that, so just remove the selected item alltogether after running the stored procedure. It will take less time and won't flash the treeview as it clears, refils and reexpands node.

I definitely had that thought as well. Unfortunately I cannot seem to get the syntax on removing the selected node. Any suggestions?

Thanks again.

It should be axTreeView.Nodes.Remove axTreeView.SelectedItem

Thanks Max! I had just got it as well with the index:

axTreeView.Nodes.Remove axTreeView.SelectedItem.Index
