sorry - posted too soon ... use the KeyDown event. check for keys.left and
keys.right. if your KeyDown handler is form-wide, dont forget to set
KeyPreview to true. "Rlrcstr" wrote:

I'm not getting an event when the arrow is pressed. I do get one when the
space bar is pressed, but not on an arrow press.
Any thoughts?

I have no problems with KeyDown getting both arrow key events and space key.
You get space but not arrow. What controls do you have on the form? Almost
certainly the arrow keys are being intercepted by a control on your form.
Search the .net help for "arrow and keydown" for interesting reading.
It's a usercontrol inside a scrollable panel container inside another
usercontrol.
I'm creating the inner usercontrols dynamically and then allowing the user
to scroll through as many as have been created. Kinda like a listbox forthe
usercontrols.
I originally tried actually using an ownerdraw listbox - it has a controls
collection - but it also has issues displaying controls when scrolling, so I
decided to create my own.
I'm very close but I still have to main issues and one of them is that I'm
not getting the KeyDown trigger when an arrow is pressed. I don't
understand why I would get other KeyDown events and not the arrows. It's
strange seems that I get every other key. I even get modified arrows (i.e.
Ctrl + Arrow) but nothing on a plain old arrow.
I will search as you suggested, but in the mean time, if you have any other
thoughts, I'm open...

I started to read something about that. How can you do that with a control

Thanks.

Yes, not hard. You don't even have to create a library to do it.

Hi,
I am stuck... I've got a popup window that displays a list in table
format with links on the bottom to navigate the list <prev> 1 2 3 ...

When I demo'd to the users... they immediately asked if they could use
the arrow keys and enter key to navigate the list. I think there must
be a way to do this, but I can't figure it out.

I then moved all the code into a user control, put it on the form. Now I
don't get keydown events when I press an arrow key - on either the form or

Hi there,
I have an application in which a grid of 100 or more buttons are put on a
form in columns of 10.
All the buttons are within a panel.
They are added in runtime, and so they adopt a sensible tab value.
The tab key moves the focus down the column one by one, and the up and down
arrow keys work well.

Hi,
I have a user control that needs to trap the arrow keys to move items
around internally. However, using the arrow keys will move the focus to
another control on the form hosting the user control.
How do I stop this?

Hi thescripts people, I hope I'm in the right forum for Visual Basic Dotnet (VS 2005).
I am trying to make a custom control in which you can nudge a point around using the arrow keys. Actually, the control is meant to be a simple drawing program. To test it out I have put the control on a Windows form which also contains several buttons.
I have added a KeyDown event handler to the custom control (see code below). It responds fine to keys...
