I remember doing this in a checkboxlist element, but with listview element its giving a hard time.
Private Sub CheckedListBox1_ItemCheck(ByVal sender As Object, _
ByVal e As ItemCheckEventArgs) Handles ListView1.ItemCheck
If e.NewValue = CheckState.Checked Then
For index = 0 To Me.ListView1.Items.Count - 1
[Code]...
In a listview with check boxes, there are two fields being loaded, ID and Lastname. With this information I want to get the ID of the person whose box is checked with this sub:
[Code]....
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...
removing Listbox item from checked Listview item.The code I tried just errors out.
Private Sub ListView1_ItemCheck(sender As Object, e As System.Windows.Forms.ItemCheckEventArgs) Handles ListView1.ItemCheck
If (e.CurrentValue = CheckState.Unchecked) Then
ListBox1.Items.Add(Me.ListView1.Items(e.Index).Text)
ElseIf (e.CurrentValue = CheckState.Checked) Then
[Code]...
This is probably easy as well. But I have this listview which contains exe files I've listed up. Now, I want to execute these exe files in turn from which items are checked or not. So, I've tried this:
For each item in listView1.CheckedItems
Msgbox item.ToString
Next
Cause I noticed that the item in checkedItems doesn't contain much. And if I convert it to a string, it ends up in the msgbox looking like this: ListViewItem: {Filename.exe}
I have a list of options on my site that a user can select. What I want to do is provide functionality to limit the amount of content the user gets based on his selection in a CheckBoxList. Once he's selected what he wants, he'll click Save and his selection will be written to the database. The CheckBoxList is initially populated from the Modules table. This provides a list of modules that the user can select. When he clicks Save, the code needs to loop through this CheckBoxList and "pick out" the values for the CheckBoxes that were checked, disregarding the ones that weren't. The problem is that whether a CheckBox is checked or not, the debugger returns a False value for the CheckBoxList.Items(i).Selected property.
Here's my code:
Private Sub AddUpdateOrg(ByVal OrganizationName As String,
ByVal Action As String, Optional
ByVal Target As Integer = Nothing)
[Code] .....
Its possible that this behavior is the result of a postback from the save button. Upon further examination of the code, I've reconsidered the possibility that this issue is caused by a postback as the CheckBoxList is not bound on page load.
Given a CheckedListBox instance, how can I accomplish that a maximum of one item can remained checked?

View 1 RepliesI trying to get what I think should be a simple thing. I have a checked treeview. I need to get the text of each checked node into a string. For the life of me I can't get it. I am trying to loop thru all the nodes and see if they are checked but I keep getting a "object reference not set to an instance of an object" but I don't know why.

Does anyone know of a control such as a Checked List Box where each item can have a value against it.For example you have a list of fruits and in the listbox it displays Apple, Orange & Banana but the values for those items are A, O & B.
View 3 RepliesWith 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
The check box list has an event called "ItemChecked" or something, which triggers when an item is about to change its checked status.
So, it is before the check occurs.I couldn't find an event that occurs after the item has changed.. I want to execute some code only when an item is checked or unchecked.
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 have a list of items in a ListView and at the top of the list there is an item that is supposed to select all the items in the ListView. I can get it to select all of the items when it's checked but then I can't deselect any other items. I need the to know which item was checked, when putting the sender into a message box I get "System.Windows.Forms.ListView, Items.Count: 1, Items[0]: ListViewItem: {All}". How do I get the sender's item?
View 6 RepliesI 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?

Then skips straight to the Else without performing the two lines in between, regardless of whether the item was checked or not checked. It doesn't crash, doesn't throw any errors, so I am assuming I coded this wrong somehow.

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'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've been trying to feed a multi line textbox into a string array then check item by item if a string contains part of it.
