Hi Robin,

can you please retest with the latest build (1.2.71). Please note that we also added a new property HtmlPanel.Scrollbars.

Best regards
Frank

A new build (1.2.71) is now available:

Breaking change

Invoke(script) has been changed to Call(script) to be consistent with Eval() and to avoid confusion with the Control.Invoke method.

New properties

TreeView.HideNodeImages, TreeNode.HideNodeImage, HtmlPanel.Scrollbars and Control.Focusable have been added.

Themes and Extensions

Also have been updated. The themes did not have the Pushed state for button in the tools.

Hi Frank,

Thanks for the enhancement. It works all right.

As far as I can see, nodes without an image are left aligned with the image of the other nodes.

Hi Tiago,

can you please send us the source code so we can double check that all issues are fixed ?

Thanks in advance,
Frank

Hi Tiago,

To be honest I was suspecting they might be related, since after tv.Nodes.Clear() the count was zero but of course the treeview had all the previous nodes. But I wasn’t sure. After all it was easy to reproduce! 🙂

Thanks Tiago!

Thanks Frank.

Hi Frank,

It’s the same issue all right.

Hi Alex,

I think you found the issue I was referring to on https://wisej.com/support/question/treeview-wrong-node-count.

Thanks 🙂

Hi Alex and Tiago,

we will introduce new properties TreeView.HideNodeImages and TreeNode.HideNodeImage to allow
control on either the TreeView or individual node level.

So there will be no need for a “hack” anymore.

I have logged WJ-7670 for it.

Hi Tiago,

this sounds related to Alex´ report:

https://wisej.com/support/question/treeview-nodes-clear

We will notify you when WJ-7669 is fixed and would appreciate if you could retry your solution then.

Best regards
Frank

Hi Alex,

I could reproduce the problem and logged WJ-7669 for it.

Best regards
Frank

Thanks Frank and Tiago !

Tiago’s sample at the end of the thread is very complete. Actually I was doing something very similar, but the key point was the call to tv.DoDragDrop() instead of simple DoDragDrop(), which, as you Frank pointed out, refers to the Form and not the TreeView.

Alex

Hi,

Has the loader icon changed? Since when? I still get the old one and I wouldn’t have suspected that it has changed if I hadn’t read this thread. I’m using version 1.2.70, Classic-2. Some caching issue?

Best,
Alex

Dear Tiago,

I wanted the same, and Frank suggested to set an ImageList item with size (1, 1). Unfortunately the space taken by the default icons is still taken, i.e there is an empty space between the expand/collapse icon and the node Label, where the node image would be if you hadn’t set a 1×1 px image. On top of that, I noticed that during collapce, the default image showed up for a split second. That was with Classic-2 and an earlier beta version, haven’t checked lately. If you find a better way let me know.

Best,
Alex
