To reproduce, run code, open file menu, press up and down arrows to move out of menu. Menu items are scrolled and blank items appears in end. I need to change visibility of menu items at runtime. How to fix this ? Is this .NET 3.5 bug ? Andrus. using System.Windows.Forms; static class Program { static void Main() { Application.Run(new Form1()); } } class Form1 : Form { public Form1() { var menuStrip1 = new MenuStrip(); var fileToolStripMenuItem = new ToolStripMenuItem(); menuStrip1.Items.AddRange(new ToolStripItem[] { fileToolStripMenuItem }); for (int i = 0; i < 10; i++) { var item = new ToolStripMenuItem("Item" + i.ToString()); fileToolStripMenuItem.DropDownItems.Add(item); if (i < 5) item.Visible = false; } fileToolStripMenuItem.Text = "File"; Controls.Add(menuStrip1); MainMenuStrip = menuStrip1; } }
Andrus, The only immediate workaround I can see would be to not add the items if you are not going to make them visible. I took your example and didn't add the items if they were not visible, and didn't get that effect. I would definitely register this bug on the Microsoft Connect site. -- - Nicholas Paldino [.NET/C# MVP] - mvp@spam.guard.caspershouse.com "Andrus" wrote in message news:%23uod8lC7IHA.3652@TK2MSFTNGP04.phx.gbl... > To reproduce, run code, open file menu, press up and down arrows to move > out of menu. > Menu items are scrolled and blank items appears in end. > > I need to change visibility of menu items at runtime. > How to fix this ? > Is this .NET 3.5 bug ? > > Andrus. > > > using System.Windows.Forms; > > static class Program > { > static void Main() > { > Application.Run(new Form1()); > } > } > > class Form1 : Form > { > public Form1() > { > var menuStrip1 = new MenuStrip(); > var fileToolStripMenuItem = new ToolStripMenuItem(); > menuStrip1.Items.AddRange(new ToolStripItem[] { > fileToolStripMenuItem }); > for (int i = 0; i < 10; i++) > { > var item = new ToolStripMenuItem("Item" + i.ToString()); > fileToolStripMenuItem.DropDownItems.Add(item); > if (i < 5) > item.Visible = false; > } > > fileToolStripMenuItem.Text = "File"; > Controls.Add(menuStrip1); > MainMenuStrip = menuStrip1; > } > } >

I took your example and didn't > add the items if they were not visible, and didn't get that effect. I have Winforms menu system designed using Windows forms Designer in MDI parent form. Some menu items may not be visible to user who logs in. I have also command "login as different user" in this MDI parent form which allows other user to log in without exiting main form. For this command I need to make some other menu items visible. How to make items visible/invisible in this case ? > I would definitely register this bug on the Microsoft Connect site.
