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]...
my form contains a checked list box [data coming from the database] a combo box [bind to a database table product] and a listview [was previously a listbox]
[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]....
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 know my question reads a bit like that 'how much wood can a woodchuck chuck' line, excuse that... I have a repeater with checkboxes. There are numerous rows in this repeater - I never know how many - I want only one checkbox checked at any time. If the user changes the checked checkbox, any pre-existing checks are unchecked therefore maintaining a single checked checkbox.
I am using VB, but comfortable to port any C#. I want to use JQuery. I have been looking on Google, but only ever seem to find ALL checked, ALL unchecked systems.
I use the code below to get the checked item value in my ilstview, i also need the subitem values (there are 2) i can't seem to figure out how.
[Code]....
how do i check if a listview checkbox has been checked and prompt the user on what he/she checked.
View 1 Replies1) 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...
I have an idea on how I want to proceed, but thought to get some ideas from you all first. I asked a similar question a while ago, but that involved different controls.I have 7 items in a ListView. If the user checks one of the items, I want a panel with three radio buttons to appear just for that item.I originally thought to make 7 panels, hide all of them, and then show and hide them when appropriate. I know this will work, but I really don't want to just overlap 7 panels and an overall 21 radio buttons.Is there a way I could use only three radio buttons with one panel? Or maybe create the controls during runtime?

Isn't there something fundamental like this? Is absolutely everything in VB.NET buried beneath a colossal heap of bureaucracy?
i want to get the row(s) when the checkbox is check/uncheck in the listview..

View 2 RepliesHave a populated listview with check boxes. If the item is checked I want to send it to report for printing. This code is bypassed:
Code:
Private Sub GetSelectedItems()
If Not Me.ListView1.SelectedItems.Count = 0 Then
[code]....
Count is always = 0. This seems to work only if the item is double clicked. And then only one item is returned in the msgbox. MSDN says "The SelectedItems property will not contain any items if the property is accessed before the ListView handle is created, which typically occurs when ListView is initially loaded for display in the form. You can check to see if the handle is created with the IsHandleCreated property."
When I tried to check for the handle, an error said something about overloading. So I added this:
Code:
Public Overloads ReadOnly Property GetSelectdItems()
Get
If Not Me.ListView1.SelectedItems.Count = 0 Then
[code]....
Which does not help. How to find the items checked/create the needed handle?
I am filling a listview control with a big number of items but i came across an problem, the repeated values. In those items i use .Text and .Tag so i can relate some hidden values per item. I have been trying to use the items.find() with no luck since it looks like to search for keys, which i don't really have. Every item has different .Tag values but it can happens that they have the same .Text Is there any way to remove or just not add items based on a .Text search in the ListView?
