Hi All:
I have a contextmenu with each menu item comprising of a set of child
menus. This contextmenu is attached to an image control and is
displayed only when the user right-clicks on the image control. I am
having trouble in clearing out the contextmenu when the user
right-clicks and selects a menu option. What happens is that while the
contextmenu itself vanishes it leaves a small rectangular box on the
screen which only vanishes when I manually do an ALT-TAB into another
window and go back to my window with the contextmenu. The code I have
within the event handler of the menu option is as below:
'Somewhere, I attach an event handler to the menu
m.MenuItems.Add ("&Event for Alarm ", New System.EventHan dler(AddressOf
Me.JumpTo_OnCli ck))
..
..
..
'Event handler for the menu option
Protected Sub JumpTo_OnClick( ByVal sender As System.Object, ByVal e As
System.EventArg s)
...
For Each mnuItem As MenuItem In ContextMenu1.Me nuItems
mnuItem.Enabled = False
mnuItem.Visible = False
mnuItem = Nothing
Next
ImageControl.Co ntextMenu = Nothing
ImageControl.In validate()
End Sub
Any suggestions as to the best way of clearing out a context menu is
most appreciated.

When selecting the Options of the Contextmenu. Try using the MouseUp event
not the mouseDown

Why don't you remove the items with
'ContextMenu1.M enuItem1.Items. Remove(...)'?

I have assigned a contextmenu to a datagrid in my WINDOWS application and I
want to use keyboard shortcuts.
I have assigned a shortcut - lets say ctrlV - but do I need to assign a
handler in the same way I have to do to capture the contextmenu.click event
(AddHandler mnuItem.Click, AddressOf RepriceJob)?
Because at present nothing is happening.

Hi,
I'm looking for a decent way to manage Commands in my Application. As in
many applications, a Command can be triggered through various actions
(Click on the Menu, Click on the ContextMenu, Click on the Toolbar, using a
Shortcut).
Is there a common pattern used for managing the creation and state of your
commands, i.e. their visibility, whether they are enabled or not, etc.?

Hi,
I found out, that a simple Form, created only with the designer, wont
Dispose its contextmenu if you show the form, right-click it, and dispose
the form afterwards.
This isnt really what I expected and causes some huge memory-leaks in my
app.
All works fine, if I add the ContextMenu to the form.components manually.
(funny, the designer tells me not to modify the InitializeComponent(), but
since it works so stupid, I'll have to)

I want to display different menu item options depending on what the user
right-clicks on the tree. I cant figure out how though,
I currently tried to create separate ContextMenu objects in a class which
inherits from TreeView, and then in it's MouseClick event I do:
protected override void OnMouseClick(MouseEventArgs e)
{
TreeNode node = this.GetNodeAt(e.Location);
this.SelectedNode = node;
