Iterate over them and build a list of ints that contains only the ones that are checked. Assuming there's no property for that already, which would surprise me.

I guess you don't have google where you live. I do, so I was able to find this:

http://msdn.microsoft.com/en-us/library/system.windows.forms.checkedlistbox.checkedindexcollection.aspx[^]

However, surely you get the full visual studio ? It has intellisense. Hit . and you get a list of methods on the object. Surely 'CheckedItems' is self documenting ?

Solution 2

I believe you were asking for this:

C#

private void checkedListBox1_ItemCheck(object sender, ItemCheckEventArgs e)
       {
           if (e.NewValue == CheckState.Checked)
           {
               MessageBox.Show(e.Index.ToString());
           }
       }
