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

Checked List Box - Delayed Check?

May 11, 2009

I'm having a hard time figuring out why this is happening. When I check an item in the listbox it calls the sub ItemCheck for the listbox accordingly:

Code:
Private Sub chklbToDo_ItemCheck(ByVal sender As Object, ByVal e As System.Windows.Forms.ItemCheckEventArgs) Handles chklbToDo.ItemCheck
Dim iLoop As Integer
Dim iCheck As Boolean

[code]....

I've had to work with the delay of the check by reversing the boolean value caused by the check. But when I worked it into the program to delete the item that is checked, it deletes the selected/(un)checked item and THEN checks the item with the index. So in other words, if a user selects and checks an item in the listbox, and chooses to delete the item, it deletes the item and then checks the item that replaces it in the index (the following item).I don't understand why the checked value doesn't appear until after the sub ends.

Asp.net - Check If A Checkbox List Item Is Checked/unchecked?

May 14, 2012

I have a checkbox list which is filled with entries from my database on page load. I need to update an entry in my database when a item is checked and when an item is unchecked. Right now I am doing the following:

<asp:CheckBoxList id="check1" AutoPostBack="True" TextAlign="Right" OnSelectedIndexChanged="Check" runat="server">

</asp:CheckBoxList>

And the function:

Sub Check(ByVal sender As Object, ByVal e As EventArgs)
Dim sql As String
If check1.SelectedItem.Selected = True Then[code]....

The error is: "Object reference not set to an instance of an object." Is there a better way to check if a list item is checked or unchecked?

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.

Create A Non-Repeating List?

Feb 4, 2012

Before getting started, I'm new to VB and currently using Visual Basic 2010 Express. Just want to make sure I've got this in the right forum and my apologies if I'm not.[code]...

I have 16 cities (those would be my string variables, right?) that I want to appear on my 16 labels in random order without repeating when I click the button. So basically label 1 can be any of my 16 cities, label 2 then will be any of 15 left available cities, and so on and so on.

Load Listbox From Database (repeating Entries)?

Apr 14, 2012

I have a program with two forms, one that handles the applications controls, and the other with the functions that open a file (csv), open a database, and query the database. The controls on the first form are a list box, three labels (to display parsed csv information), and three buttons (clear database, load database from csv, and load listbox).

The clear database and load database buttons (events) seem to function correctly.On the other hand, the load list box event doesn't function 100% the way I'd want. [And, I can't test the selected index event yet]

The code for the load list box event is:

Code:
Dim db As New DBUpdt 'second form
b.openConnection("weather.mdb") 'open database connection
db.query("SELECT * FROM stations") 'query database
Do While db.moreRecords

Placing Selected/unselected Items In Checked List Box Into List Boxes?

Mar 16, 2011

This program is supposed to allow the user to check items in a checked list box. If the item is checked, it goes into the Completed List Box on the right. The program then adds the unchecked items to the Pending list box on the left. I keep getting placement values (e.g. O,1,2) instead of the strings (e.g. "Key Returned") in the list box results (see photo attached)

Public Class frmCheckOut
Dim i As Integer
Dim cleaning As String = "Cleaning Inspection"
Dim damage As String = "Damage Repaired"

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.

Aug 11, 2010

I have group of radio buttons, each group ranges from 5 - 27 radiobuttons. And if any radio button in a group is checked I store 1 in db else I store 0.

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.
