ToolStripMenuItem.visible always false

Hello

I have a problem with the "visible" attribute of ToolStripMenuItem.

I have a form with a ToolStrip containing two ToolStripMenuItem buttons. I've been setting the visible attribute of these two buttons to false depending on the users permissions.
I'm now trying to re-size the ToolStrip according to how many of the buttons are visible. The problem occurs when I come to test the value of ToolStripMenuItem.visible.
It always seems to be false until the form has completeley finished drawing. So I can't count how many of the buttons are going to be visible.

How can I accurately test the visible attribute of a ToolStripMenuItem ?

It is true, visible property of ToolStripMenuItems is false until the form is loaded. You should handle Load event of the form and set there this property.

Note: ToolStripMenuItem can be part of a MenuStrip or a ContextMenuStrip control. If you use a ToolStrip containing ToolStripButtons you have ToolStrip.AutoSize property you can use, but again, visible property for ToolStripButtons should be set in Load event.

Thankyou

Using the load event of the form solved my problem.
Although I don't see how the ToolStrip.AutoSize is of any use. I still had to re-size the tool strip myself.
At what point is the AutoSize property supposed to take effect?

By default, ToolStrip has Dock property set to Top or Bottom. The resize can only take place if Dock is set to None, otherwise the size is linked with the size of the container.

That's strange. My toolstrip is not docked at all, and AutoSize is set to true. Yet it doesn't appear to perform any sort of auto re-size.

It seems that the 'Available' property reflects whether the item has been set to visible or not.
