.NET

[#1]

My .NET application creates a new PaletteSet using a user control that has a
TreeView on it. The TreeView allows label editing, but once you are in label
editing mode, the control does not respond to either ESC or ENTER. I seem to
recall having to deal with this issue in a similar ObjectARX application,
but I'm not sure how to fix it in .NET.

Below is a snippet of code that demonstrates this issue:

With New Autodesk.AutoCAD.Windows.PaletteSet("Test Palette")
Dim objTreeView As New System.Windows.Forms.TreeView
With objTreeView
.Dock = Windows.Forms.DockStyle.Fill
.LabelEdit = True
.Nodes.Add("Edit this node")
End With
.Add("Test Palette", objTreeView)
.Visible = True
End With

Any ideas?

I assume you have coded the node's KeyUp event to handle Enter and/or
Escape?

Oops, let me rephrase that.! What I meant to say was have you tried
throwing code into the keyup event for the treeview and the palette to see
if the event registering at all one either of those keys? If not, you may
need the same fix for focus as the combobox control.

Hi Mike,

Thanks for the reply. The PaletteSet and Palette classes don't appear to
expose any keyboard events themselves. I tried putting some code into the
TreeView's KeyUp event and found that it responds to ESC and ENTER. But when
you go into label edit mode (and the TreeView control creates a temporary
edit box control to edit the label) those keys seem to be ignored - in fact,
the TreeView_KeyUp event is not fired at all when the label edit box is
visible.

Hi Mike. You might be interested in knowing that
the 'fix' you posted for the ComboBox problem (for
not dropping down when you click on the control
while the palette is floating), actually creates more
problems than it solves.

One of those problems is that it corrupts the behavior
of any control that displays an "in-place" edit window
(e.g, TreeView, ListView, DataGrid, etc.).

With your fix, if you try editing a label in a treeview
or listview, and you click inside the label edit window
with the mouse, the label edit window looses and
regains focus, with the entire label text selected.
What should happen is that you should get a vertical
blinking bar cursor at the point where you clicked in
the control, but that doesn't happen.

I haven't looked at the problem with the treeview
(and it should also affect ListViews as well), so I
don't know exactly what's causing it.

Ouch! Sorry, I didn't mean for that to happen =( Chalk another one up to
"slap it in and see if it works to get me to the due date and I'll sort it
out later"

I'll look at it and weed out the crap and see if I can't revise it with
just the focus you mentioned, Tony. Thanks!

This TreeView control descendent should solve your problem.
Just use it in lieu of the Syste.Windows.Forms.TreeView.

Sorry about the C#, but I don't do VB. Hopefully, somoene can
translate it for you, or you can build it a separate assembly and
reference it from your VB project.

The code below has a major bug. Don't use it.

See the next post for a fixed version.
