Dynamic add to context menu only works 1st time??

[Ed Sutton]

I am dynamically appending to a context menu when user right mouse clicks on
a treeView. The first time I right-mouse click I see the appended menu.
Subsequently, the menu items I append do not display.

this.contextMen u1.MenuItems.Ad dRange(new System.Windows. Forms.MenuItem[]
{this.mnuParent });

private void treeView1_Mouse Down(object sender,
System.Windows. Forms.MouseEven tArgs e)
{
if( e.Button == MouseButtons.Ri ght )
{
mnuParent.MenuI tems.Clear();
for( int iNumMenuItem = 0; iNumMenuItem < 9; iNumMenuItem++)
{
MenuItem mnu = new MenuItem("Test Menu " + iNumMenuItem );

mnuParent.MenuI tems.Add(mnu);
}
contextMenu1.Sh ow(this, new System.Drawing. Point(e.X, e.Y));
}
}

Thanks in advance for any tips or suggestions,

Re: Dynamic add to context menu only works 1st time??

I think they do display but not every time. ;-)
Saying that the rest of your code is correct,
the only problem you have is that you used

contextMenu1.Sh ow(this, new System.Drawing. Point(e.X, e.Y));

and not

contextMenu1.Sh ow(this.treeVie w1, new System.Drawing. Point(e.X, e.Y));

With this call you have associated the contextMenu with the form and not with the treeView Control.
Hope this helps! Greetings,
timtos.

Re: Dynamic add to context menu only works 1st time??

timtos,

Thank you very much for looking at this.

I have the same problem after changing the code as you suggested. The menu
displays every time I right-mosue click, but only the first time displays
the dynamically created menu.

contextMenu1.Sh ow(this.treeVie w1, new System.Drawing. Point(e.X, e.Y)).

I will go beat my head on the wall some more...

Thank you very much for your suggestion,

-Ed

Re: Dynamic add to context menu only works 1st time??

You still have the same problem?
That is nearly not possible. I´ve tried it out myself now and for me your source is working!
Have you associated the contextMenu with the treeView?

Greetings,
timtos.

Not intentionally. I simply drag and dropped a contextMenu on my main form.

How do you associated a contextMenu a treeView control?

I pasted all code from my main form class below.

You can do it with visual studio. Just look for the property ContextMenu
in the TreeView properties! There is a combobox, where you can select
your contextMenu.

Or do it in the code - like this:
this.treeView.C ontextMenu = this.contextMen u1;

Hope this finally helps ;-)
