We have an application with an mdicontainer form which has a menustrip with many toolstripmenuitems. Each of these toolstripmenuitems has dropdown items. We want to be able to set the Visible properties of these dropdown items to true and false in various situations. We are able to do this e.g, mnuFileOpen.visible = True and it does make the menu item visible.

I have my program set up to read the contents of a Directory, and then populate a drop down menu with the names of the files in the directory. (I am using the MenuStrip). Inside my program, it is also set up to create a new file in that directory, and I wish to add this item to the dropdown menu upon creation. The list is entirely created and populated from the code, and the contents of the list depend entirely on what's in the directory.
I have tried using MenuStrip.Items.Remove(menuItem1). Now, when this command gets executed, it does remove the top level Menu, however when I go to repopulate the menu, I end up with duplicates of my files listed in the drop down. I am stuck with how to clear these out as well?
I'm trying to show a drop down menu when i click a button, thus i need it to popup where the mouse clicked (mouseposition.x/y).[code]
View 6 RepliesI have this
Dim oLanguages As SortedList = Languages() 'Languages() is my custom Function
Dim oLanguageMenu(oLanguages.Count) As ToolStripMenuItem
For n As Integer = 0 To oLanguages.Count - 1
[Code]....
The last line produces an error: "value cannot be null. Parameter name: value".
Is there a way to specify the index of a ToolSTripMenuItem in a MenuStrip when adding it so that it does not get added to the end of the list?[code]

View 1 RepliesWhen I try to set a MenuStrip Item calling it by name it gives me an exception?
An unhandled exception of type 'System.NullReferenceException' occurred in Sample.exe
Additional information: Object reference not set to an instance of an object.
Either of the following statements cause errors.
frmMenu.MenuStripfrmMenu.Items(key:="Enter").Enabled = False
frmMenu.MenuStripfrmMenu.Items("Enter").Enabled = False
However when I call Items using an integer it works perfectly.
I have found if you put a text box into a menustrip item everything under that menu no longer show it's properties when clicked and double clicking on the item does not got to the code until you click outside the menustrip. This behavior is only present when the menustrip render mode is system and only when a textbox is in that menu item. Fails with visual studio 2005 and 2010. Am using visual basic. Changing render mode from system to anything else makes everything work, change it back to system and it does not work. This only happens with a textbox in the menu strip item.
View 1 RepliesI want to show a ContextMenuStrip beneath a MenuStrip item when that item is clicked. Stuff in the ContextMenuStrip changes dynamically. The ContextMenuStrip is used in a DataGridView. I don't want to duplicate the same items in the MenuStrip.
I can get the mouse coordinates OK, but I don't want that. I want to use the ContextMenuStrip show method referenced to a control. An item in the MenuStrip is not a control, but the entire MenuStrip is a control. If I can get the x-y position of the item in the MenuStrip I can show the ContextMenuStrip in the right place, and it will look just as if it was part of the MenuStrip. how to obtain the location of the MenuStrip item that's active.
I have a MenuStrip with several items in it. All I am trying to do is select(check) only one item at a time.
Example: Lets say I have a menu title Fruits, and under the menu are several fruits.
Currently, when I click on one fruit there is a check mark, good! The problem is when I click on another fruit there is also a check mark and so on. I only need the menu to check one item at a time, this will unchecked an item if I check another menu item. I tried using if statements but doesn't even come close to working. Any ideas on this?
I have code which runs in a menu item (StartToolStripMenuItem_Click).Later in the project i want to code clicking this menu item but if i just use the StartToolStripMenuItem_Click sub it wants the 'e' argument passed to it. I simply can not work out what i should be passing.....

View 1 RepliesI am not sure how I could achieve this: allow the user to select a value (string) from the dropdown list of a ComboBox and display another value in the editable text. The user can modify this displayed value as well. In VB6 I had a combobox where the list property contained a two dimensional array. When the user selected a value from the dropdown list, the displayed value was set using the second dimension of the array. Something like this:
