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.

Listbox Items Colour - Two Types Of Items Populating In A Listbox (checked Listbox)

Apr 28, 2009

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.

How To Know Which Items Are Checked In ListBox

Aug 10, 2011

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.

Show Multiple Checked Items From A Listbox In A Label?

May 14, 2010

I 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.

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)?

I'm trying to remove all the checked items in my CheckedListBox. I started by doing

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.

Forms :: Scroll To Selected Items In Checked List Box?

Apr 29, 2011

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.

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:

VS 2010 - Recursion Error With Checked Menu Items

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.
