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?
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 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.)
View 3 RepliesHaving some issue trying to programmatically check items in a CheckedListBox.What i am trying to achieve:
1. Pull Staffnames from database
2. Separate each staff member via delimiter
3. checked = true for each item in StaffCHKlist where staffnames = existing StaffChKlist item
i have had a few goes, but cant seem to achieve, this is where i am currently at:
Dim sl As String = ds.Tables("Consignment").Rows(0).Item("StaffName")
Dim tokens As String()
tokens = sl.Split(",")
[code]....
which errors with:
"List that this enumerator is bound to has been modified. An enumerator can only be used if the list does not change."
I have been trying to understand, would programmatically checking an item in a checkedlistbox be classified as list change?
Given a CheckedListBox instance, how can I accomplish that a maximum of one item can remained checked?

View 1 RepliesI 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.
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 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 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'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:

I Have a problem with trying to get a checkedlistbox to work the way i want it to... Here are the 3 tables that i'm using. The links are shown in colour.

I have a checkedlistbox in a windows form: A Name textbox is linked to The Name in the Usertable
1.The DisplayMember in the checkedlistbox in the Area (Text) from the AreaID Table. This bit Works.

2.The ValueMember need to be the AreaID from the UserAreaTable
I need to do it this way because it allows me to add multiple areas to users, and add new area's without having to change the forms.
So ive Almost got Most of the Beggining Stuff done. but there's one thing. How do i get it to Save Its Data for the CheckedListBox?

However, the value of the count is always 0 when the form closes after clicking OK.
I am new to the forum and to VB, and not great at coding in general.I am learning, and this site as well as others have helped me get farther than I ever imagined. Second, my project is purely for my benefit, so I can learn.There is no corporate or school related goal here, just trying to learn.So the title is a summary of what I want to do. I have a form with a combo box that has five different choices, and below it, a checked list box. What I want is the collection inside the checked list box to change depending on what I select in the combo box above it.For instance, I have room 1 - 5 in the combo box, and the the checked list box below it, I have the furniture associated with that room.The eventual goal is to have this form populate a database, that allows the checked furniture to be recorded in a record.
I assume I need to use a db, such as access, to list the "furniture" in each room, and have a different table for each room, where the combo box selection will populate the checkedlistbox from the appropriate tables contents.I need a step by step on this, because I am a bit of a brick. Most tutorials are also done in VB 6 or VB 2008, and there have been steps missing in association to VB 2010.
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.

project im working on for my course,the idea is a photo printing machine that loads up 4 images if usb stick is checked and a different 4 if memory card is checked. and then whatever image is selected appears in the big picturebox on the left [URL] i have 2 print size options set as radiobuttons, radiobutton 1 = 6x4, which costs 25cent per photo, radiobutton 2 = 8x10, and is 50cent per photo.i also have a textbox which will display the number of copies to be printed So here's my dilemma, when the print button is selected alongside one of the radiobuttons i want it to display a message saying something like this "you have selected (whatever the amount of copies)of this photo sized 6x4, or 8x10 depending on which radiobutton is selected, and i want it to display the total cost which is the number of copies multiplied by the rate for the print size selected, then an option saying "Do you wish to proceed" Yes or No.
I did something similar to this in class earlier in the year but cant remember it, it was an airline booking program with 3 types of payment cash, visa or mastercard,upon booking a message popped up saying there is a certain percentage discount for using visa or mastercard
I am having difficulties populating a checkedlistbox (CLB) based on the selection(s) made in another. It should also be noted that I have a "Select All" checkbox at the top that checks/unchecks all of the items in the first CLB. Here's the code:
[Code]...
The first CLB is populated with an arraylist of values on the button click event. Based on whatever is checked in the first CLB, corresponding values from an arraylist of structures should fill the second CLB.The following code partially works until the "Select All" checkbox is clicked at which point if other values have been selected before "Select All" is checked, the second CLB is filled with the correct number of corresponding values BUT only those of the most recently selected item of the first CLB instead of all of corresponding values of all of the items that were not already selected.

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.
How do I write code to bypass a messageBox, and go to a Textbox If the checkBox is checked

I have a form with a ContextMenuStrip Added and a Listview. I set the 'ContextMenuStrip' property on the listview to my newly created ContextMenu.

I would like to copy the value of a check box when it is checked and I have two checkboxes. CheckBox1 and CheckBox2. Id like to be able to click 'Submit' and copy the values from the Checked CheckBoxes. Idealy, if both are checked then it would return something like this "CheckBox1, CheckBox2".
