Hi . I have set up some events for listview on windows form where some events (keydow, rightclick ..) will change listview's cell value, others will work if detecting this value change ( give notice to users, ....)
I used some events:
listview_ItemValuechanged
listview_Text
listview_ItemEdite
listview_ItemValuechanging
however they do not seem to be detected when a change in value occurs from another event

How can i implement this idea?

Thanks a lot

Hello Khanh,

In this case you can use the CollectionChanged event which fires before the cell value changes:

radListView1.Items.CollectionChanged += Items_CollectionChanged;

private void Items_CollectionChanged(object sender, Telerik.WinControls.Data.NotifyCollectionChangedEventArgs e)
{
    if (e.Action == Telerik.WinControls.Data.NotifyCollectionChangedAction.ItemChanged)
    {
        //TO DO
    }
}

I hope this helps. Should you have any other questions do not hesitate to ask.

Regards,
Nadya
