Treeviews and Images

[AccordingToDale]

Hey there,

Does anyone know if you can use images in a treeview, but only for certain nodes?

As an example:

- root node (no image)
|
|- child node (with image)


So far I've only managed all or nothing.

You would think this would be possible, but I can see why it moght not be - if you don't set the ImageIndex for a node, it automatically uses the first image in the ImageList used for your tree.

I guess you could create a "blank" image in your ImageList, and set the node to use that image.

Yes you can...
How are you building your tree view?. My preferred way to control Images is to add an event handler, and Raise the Event just before the Node is added. This way because the Node is exposed in the Event you can set its Imageindex with n.ImageIndex and n.SelectedImageIndex

Dont forget to tie the ImageList to the Tree control either.

'Define Event
Public Event AddingNode(ByVal sender As Object, ByVal n As TreeNode, ByVal dr As DataRow, ByVal iLevel As Integer)

'Raise Event before Node is added
RaiseEvent AddingNode(Me, oParentNode, oParentRow, 0)
Me.Nodes.Add(oParentNode)

So, either way, you still have to have a blank image to mimic having no image.

That was the way I was dealing with it, but I was hoping there was a way around this as adding a blank image leaves a gap between the treeview lines and the text. Not a big deal, but...


Thanx anyway.
