Question

I currently have a CheckedListBox with several boxes. I want to be able to test every Checkbox in the list to see if it’s checked, and if it is, add it’s text value (CheckBox.Text) to a List of strings.

Here is what I have:

for ( int i = 0; i < multiTaskChecks.Items.Count; i++ )
{
    if ( multiTaskChecks.GetItemChecked(i) )
    {
        checkedMultiTasks.Add(multiTaskChecks.GetItemText(i));
    }
}

Using this, GetItemText is returning 0, 1, 2, 3, etc instead of the text values that I’m after. I have also tried CheckedListBox.Text.IndexOf(i), CheckedListBox.Text.ToList(), each without any luck.

I just cannot get the label text of one of these CheckBoxes from the CheckedListBox. Any help with this would be really appreciated.

Firstly, you should be able to loop through the checked items only like so

foreach (var item in multiTaskChecks.CheckedItems)
{
}

then depending on the type of the item, get whatever property you want from it. Sounds like it is just a Text or you just want the string, so

foreach (var item in multiTaskChecks.CheckedItems)
{
    checkedMultiTasks.Add(item.ToString());
}

or I prefer

checkedMultiTasks.AddRange(multiTaskChecks.CheckedItems.
    OfType<object>().Select(‌​i => i.ToString()));
