VS 2010 ContextMenuStrip Item Checked?
Dec 24, 2011
I have a form with a ContextMenuStrip Added and a Listview. I set the 'ContextMenuStrip' property on the listview to my newly created ContextMenu.
So, I am creating the Menu items from a database (no problems here). But I cant seem the get certain menu items to a checked status when creating the menu item from the database.
The Code below is a sample of what I am using.
Public Sub LoadMenu(_Menu As ContextMenuStrip)
Dim n As Long = 0

Then skips straight to the Else without performing the two lines in between, regardless of whether the item was checked or not checked. It doesn't crash, doesn't throw any errors, so I am assuming I coded this wrong somehow.

This is probably easy as well. But I have this listview which contains exe files I've listed up. Now, I want to execute these exe files in turn from which items are checked or not. So, I've tried this:
For each item in listView1.CheckedItems
Msgbox item.ToString
Next
Cause I noticed that the item in checkedItems doesn't contain much. And if I convert it to a string, it ends up in the msgbox looking like this: ListViewItem: {Filename.exe}

I have a list of options on my site that a user can select. What I want to do is provide functionality to limit the amount of content the user gets based on his selection in a CheckBoxList. Once he's selected what he wants, he'll click Save and his selection will be written to the database. The CheckBoxList is initially populated from the Modules table. This provides a list of modules that the user can select. When he clicks Save, the code needs to loop through this CheckBoxList and "pick out" the values for the CheckBoxes that were checked, disregarding the ones that weren't. The problem is that whether a CheckBox is checked or not, the debugger returns a False value for the CheckBoxList.Items(i).Selected property.
Here's my code:
Private Sub AddUpdateOrg(ByVal OrganizationName As String,
ByVal Action As String, Optional
ByVal Target As Integer = Nothing)
[Code] .....
Its possible that this behavior is the result of a postback from the save button. Upon further examination of the code, I've reconsidered the possibility that this issue is caused by a postback as the CheckBoxList is not bound on page load.

Does anyone know of a control such as a Checked List Box where each item can have a value against it.For example you have a list of fruits and in the listbox it displays Apple, Orange & Banana but the values for those items are A, O & B.

With my CheckedListBox, I am trying to get the text of each item that is checked and add it to a listbox, but it does not get everything currently checked. If I have 3 items checked, it only adds 2 items. If I deselect an item, it appears.
lstOpCodes.Items.Clear()
Dim OpCodeCollection As CheckedListBox.CheckedItemCollection
OpCodeCollection = chkOpCodes.CheckedItems
For Each opcode In OpCodeCollection
lstOpCodes.Items.Add(opcode)
Next opcode

The check box list has an event called "ItemChecked" or something, which triggers when an item is about to change its checked status.
So, it is before the check occurs.I couldn't find an event that occurs after the item has changed.. I want to execute some code only when an item is checked or unchecked.

I have a list of items in a ListView and at the top of the list there is an item that is supposed to select all the items in the ListView. I can get it to select all of the items when it's checked but then I can't deselect any other items. I need the to know which item was checked, when putting the sender into a message box I get "System.Windows.Forms.ListView, Items.Count: 1, Items[0]: ListViewItem: {All}". How do I get the sender's item?

I have a checkbox list which is filled with entries from my database on page load. I need to update an entry in my database when a item is checked and when an item is unchecked. Right now I am doing the following:
<asp:CheckBoxList id="check1" AutoPostBack="True" TextAlign="Right" OnSelectedIndexChanged="Check" runat="server">
</asp:CheckBoxList>
And the function:
Sub Check(ByVal sender As Object, ByVal e As EventArgs)
Dim sql As String
If check1.SelectedItem.Selected = True Then[code]....
The error is: "Object reference not set to an instance of an object." Is there a better way to check if a list item is checked or unchecked?

1) Can I set a CheckedListBox item to be disabled programatically so that it cant be checked?
2) Why doesn't the SelectedIndexChanged event fire when I check or uncheck an item programatically? But it does if I do it manually...
