Hi people, first post here =]
I have a C#.Net program that has 3 forms ( frmMain, frmPrint, frmAudio.) Each of the three forms have a listbox, frmPrint and frmAudio have values in the listbox which the user can select and then the listbox control on frmMain gets updated with whatever values they select.
I need to do some calcuations on the values that are entered on frmMain listbox. The problem is I can't seem to find the right event so I can calculate these values on the fly whenever the listbox has a item added or removed.
foreach
{
txtShipping.Text =
}
I've tried the SelectedIndexChanged and SelectedValueChange and the form_Load and form_enter events with the above code, none work. the selectedIndexChange requires me to click an item in the listbox. This is not what I want.
I want it to automatically and on the fly do the calcuations (or in the above code, display the text in the textbox.)
Am I clear here? Advice/suggestions please.
