Count Number Of Items Checked In A CheckedListBox?

Mar 25, 2010

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.

VB
'
Dim i As Integer

[Code]....

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).

How To Remove All Checked Items In CheckedListBox

Jul 3, 2009

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.

Update A Label To Indicate How Many Items In A CheckedListBox Are Checked

Mar 1, 2012

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.

Saving CheckedListBox's Items, Retaining Checked State?

Jun 11, 2011

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'm trying to count the number of checked checkboxes in column 5 of the table. I've tried several approaches, but none have worked so far.This is the code I've written so far. As you can see, I've managed to count the number of rows.

VS 2005 Check Grid Items If Checked ListBox Items Checked?

Aug 21, 2009

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.

Private Sub CheckedListBox1_ItemCheck(ByVal sender As Object, ByVal e As System.Windows.Forms.ItemCheckEventArgs) Handles CheckedListBox1.ItemCheck

Got A Checked Listbox On Form Which Saves The Checked Items?

Jun 6, 2012

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.

VS 2008 - Linq Statement To Go Through A Dropdown Menu's Sub Items And Get What Items Are Checked

Apr 8, 2010

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)?
