How do I get the set of checked items in a checkedlistbox when an item is checked or unchecked, given that ItemCheck event occurs before the check state is actually updated? (The SelectedIndexChanged event won't work in my case.)

I have CheckedListBox and four item in it!Now I want to count number of checked item. For this I use:
countnumber=CheckedListBox1.CheckedItems.Count
But countnumber is always 0 even if I checked CheckedListBox items or not!
I'm trying to remove all the checked items in my CheckedListBox. I started by doing
CheckedListBox1.Items.Remove(CheckedListbox1.CheckedItems)
That seemed like it would work, but it didn't. I soon discovered that CheckedListBox1.Items.Remove only works on the the strings of the individual items.
I am trying to get the number of items that are checked in my CheckedListbox. The Items.Count seens to only reference the entire collection so I am not sure how to narrow the count down to only the ones with checked boxes.

Basicaly I have the option for the user to print a series of reports directly to a printer that is not located in the same area as the application user. I want to show the user a progress bar how far into the process they are but I can't do it without getting the Maximum value of the Progress Bar (number of reports checked for printing).
I'm trying to update a label to indicate how many items in a CheckedListBox are checked. Here is the code I'm using:
Private Sub CheckedListBox1_ItemCheck(ByVal sender As System.Object, ByVal e As System.Windows.Forms.ItemCheckEventArgs) Handles CheckedListBox1.ItemCheck
Me.Label1.Text = "(" & Me.CheckedListBox1.CheckedItems.Count.ToString & ") of (" & Me.CheckedListBox1.Items.Count.ToString & ") Items Checked"
End Sub
It should say "(x) of (y) Items Checked" each time an item is checked or unchecked, but it's not updating the label properly, the count is always off by 1.
I'm trying to program a personal project, but I've hit a bit of a bump in the road.I've got a Button, a Textbox, and a CheckedListBox; when the button is pressed, whatever is in the TextBox is added to the CheckedListBox. However, when the form is closed and reopened, all of the CheckedListBox's items are no longer present. My CheckedListBox's name in the code is ZapList.
Can someone assist me in, not only saving all of the CheckedListBox's items, but retaining whether or not they were checked as well as the order they were in? I've run out of hair to pull (figuratively) and I really don't want to quit this project, too much effort has gone into it and I'd hate to see it go unfinished like my numerous other projects. :icon_cry:

how to Checked Specific Items in CheckedListBox programmatically in visual basic 2010 CheckedListBox Items are like below
0, Apple
1, Orange
2, Banana
i want Checked Orange
Me.CheckedListBox1.SetItemChecked(1, True) it's working great
this case i know Orange's Index number 1. but if more than 2000 records how to know index number..?So i am specific "Orange" Means String Name?
Why is this code having the opposite effect? If It's checked in the checkedlistbox it's not check in my view, if it's not check in my checkedlistbox it is checked in the grid.
EDIT: More specifically. The CheckState.Checked is always the opposite. .Checked means it's not checked.

I'm working on a To Do List program of sorts. I currently have a CheckedListBox on the form with an Add Button and a Delete Button. I send the items to an array and then use that array to fill in my CheckedListbox. This all works.
I wrote the following code to delete items:
Dim summarylistboxindex As Integer
summarylistboxindex = SummaryListBox.SelectedIndex
MonkeysTasks(summarylistboxindex) = String.Empty
[Code]....
I use a variable called INTCOUNTER to keep track of my position in the array.
My question:
How can I use the second piece of code that deletes multiple items at once from my CheckedListBox AND delete the corresponding entry in the array?
ie if my checkedlistbox items were Apple Orange and Banana
I want to delete Apple and Banana at the same time and then remove them from Fruits(0) and Fruits(2) at the same time they are deleted from the CheckedListBox.
Given a CheckedListBox instance, how can I accomplish that a maximum of one item can remained checked?

View 1 RepliesI've got a menu with checkable items that appears on two different forms, and I'm making sure the two forms always have the same check states, so Form1 would have something like this:
Private Sub mnuWarnings_CheckedChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles mnuWarnings.CheckedChanged
'when one of these is checked, the other should also be
[code].....
But that yields this error:
An error occurred creating the form. See Exception.InnerException for details. The error is: An error occurred creating the form. See Exception.InnerException for details. The error is: The form referred to itself during construction from a default instance, which led to infinite recursion. Within the Form's constructor refer to the form using 'Me.'
There definitely aren't any references to Form1 within Form1.It only occurs when I use CheckedChanged--if I use mnuWarnings.Click, it works fine. And it only occurs in Form1 (the main form); CheckedChanged works fine on Form2.
I want to display distinct items from a column in a checked list box then make a selection or selections and perform commands based on info from a second column in that database the database is a small Access 2010 database in the application directory right now I added the data source and items dont display even though I selected that source in the checked list box properties
Dataset = MyDataSet1
CheckedListBox = MyListBox1
I tried it with a combo box and it shows items but includes duplicates, did I setup the datasource wrong?
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
I want to adding checked item from checkedlistbox to my combobox, but i have a little problem here.Combobox only show 1 item last checked.This is my sample code.
If CheckedListBox1.CheckedItems.Count <> 0 Then
For i As Integer = 0 To CheckedListBox1.CheckedItems.Count - 1
cbCheckedItem.Text = CheckedListBox1.CheckedItems(i).ToString
Next i
End If
I've got a checked listbox on my form which saves the checked items to a spot in my database on the .ItemCheck event.But there's a problem, when I begin checking items, I check the box and click off it, but it doesn't save. (This is if I've only chosen one item)
If I choose two or more items it will save, but unchecking them takes a lot of clicking around to figure it out.Is there a better event that I can use? I've tried the SelectedIndexChanged and that has the same result, there's a lot of clicking around in the checkboxes to end up with the desired selected items, and it does not allow a single item.
I want to use property bindings under application settings to store settings for my program. However I have run into a problem. For some reason the checked property is not binding to drop down menu item's checked state. The binding works for text boxes and other controls. I have tried to bind both using the checked property, and checked state property. Auto check on click for the menu items are set to true.
Anyone have any recommendations in getting the app-settings property binding to work without the need to manually set that info and manually run My.Settings.Save?
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...

how to make a filter that only show the items that checked and unchecked don't show in checklistbox
I have the following linq statement to go through a dropdown menu's sub items and get what items are checked: vb Dim UnselectedItems = From xItem As ToolStripMenuItem In tsiSelectObjects.DropDownItems Where TypeOf xItem Is ToolStripMenuItem AndAlso CType(xItem, ToolStripMenuItem).Checked = False
I get this error tho: Unable to cast object of type 'System.Windows.Forms.ToolStripSeparator' to type 'System.Windows.Forms.ToolStripMenuItem'. As you can probably guess i have ToolStripMenuItems and separators in there
However the AndAlso should short circuit in the case where the item is not a ToolStripMenuItem and it doesn't seem to be doing so (as TypeOf xItem Is ToolStripMenuItem=false in this case)?

I have a CheckedListbox on my form which the user chooses the item/s necessary and then proceeds to calculate a few things which end up being displayed in a datagridview.The items are settings on how the calculations should work, if they want to include the client's goals, or reduce their income, etc. My question is this; what is the best way to save the CheckedListbox checked items when they click a button 'Save as default'? And once they open the form, if the user has already input their default settings how do I get these to display once the form is

View 22 RepliesI am trying to use a checkedlistbox to tell how many of the items are selected. I can figure it out when I click a button. What I would like to happen is that when I check or uncheck the box I would like it to oupdate. Not wait until the index is changed. It would be nice if the checkedlistbox would throw an event when the spacebar is used to check and uncheck?
