I was wondering if there was any tut on how to aan item to a checked listbox thats already populated?
I thought of making a button and a text box .and when u push the button it add whats ever in the text box to the checklist box .
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 am using VB.NET (version 2008). I have two types of items populating in a listbox (checked listbox). For example: lets say one is type "A" and other is "Type B". Their names maybe same so if the user sees those items in listbox then he won;t be able to determine their type until he click on them and checks out its properties. I wanted that I add each item to listbox and colour them so that blue for example means type "A" is there and red means the other. So this way I will be able to know at a glance that how many item of what type is present. I guess it may not be possible to do that in a standard checkedlistbox. I am also using component factory's krypton controls which enhance the gui of an application. But I dunno if I can progress using that.
View 5 RepliesI'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 am reading information on missed deadlines from a database. For each missed deadline I add a item to the checked listbox and store the deadline's information in an array. I now want to disiplay all the selected (in the checkedlistbox) deadlines' information in another control, but at the moment I am getting an error. This is the code I am currently using to check which items have been selected
Dim x as integer
For x = o to array.count - 1 do
If checkedlistbox.GetItemChecked(x) = true do
'Here I am displaying array.item(x)'s information in the other control
end if
next
1) Say I have five items in the checked list box and I select all five items, when it gets to x= 3 it gives me the following error "ARGUMENT OUT OF RANGE EXCEPTION was unhandled: InvalidArgument=Value of '3' is not valid for 'index'. Parameter name: index"
2) Say I have five items in the checked list box and I select ONLY the first two items, when it gets to x=4 it gives me the same error as above only for the number 4.
I have tried the methods/functions GetItemCheckedState, SelectedIndices and GetSelected as well, but they all give the same or similar errors. According to me the index cannot be out of range as I have five items in the checkedlistbox as well as the array.
Is it possible to count how many checked items there are in checkedlistbox and then display that number in a textbox?

How do I display Items that are Checked from a treeView in a listBox using VB?
View 1 RepliesI am trying to display multiple check items from a listbox into a label seperated by a comma. Everything is working fine but the only problem is that when i check first item in the listbox nothing happens and when i check the second item then the label shows the first item. Then when i click third item the label shows the first and the second item and so on. When i uncheck the item it does the same
My question is why it does not show the items in the label as they are selected.

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 am able to have checked menu items show the variables that I need to show, but they don't uncheck themselves unless I go back and click them. I want to have only one checkmark on a country at a time...is there any way? I've tried if...elseif , but that doesn't work....example below (If I only want Mexico checked and NOT United States, but both are checked still).
If MexicoToolStripMenuItem.CheckState = CheckState.Checked Then
UnitedStatesToolStripMenuItem.CheckState=CheckState.Unchecked...

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 have two menu items from which I choose the interface language of a program (English or French).I want either of them to be chosen, both can not be chosen at the same time. I went over the properties of ToolStripMenuItem object and saw three properties that are confusing (Checked, CheckState and CheckOnClick), how can I mix them so that I get that functionality, I mean that when I check the French, the English gets unchecked and vice versa.
View 1 RepliesI'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've searched the forums and have only found similar things for ASP but not this exact function in VB.

I've been working on this for a few days and I'm trying to put a counter for the items in the check box lixt that are checked; so that the label shows the number.
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've got a Checked List Box full of PC names that the user can check. I've also got a Combo Box that lists the location of the PCs - if the user chooses one of the locations in the Combo Box, it automatically selects all of the PCs in the Checked List Box that are at that location.
However, if that group of PCs are way down the list in the Checked List Box, you can't immediately see that they were checked.I'd like to know if there was a way to have the application automatically scroll/jump down to the area of the Checked List Box containing the PC's that were just checked.
I need help on passing checked list view items into one message box. my current code outputs multiple message box with the name of the item, depends on the number of items checked. what i need is to output into a message box all the items checked in my list view. the items should be posted in multiple lines. is there any way i can do it.

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'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:

[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.
