I am working on WPF and I am using a ListView, and I need to fire an event when an item is added to it. I have tried this:
var dependencyPropertyDescriptor = Dep
Note: This solution was meant for a WinForms ListView.
In my case I ended up coming to a fork in the road with 2 choices...
(1) Create a custom ListView control that inherits a ListView's class. Then add a new event to be raised when any item is added, deleted, or ListView is cleared. This path seemed really messy and long. Not to mention the other big issue that I would need to replace all my original ListViews with the newly created Custom ListView control. So I passed on this!
(2) With every add, delete, or clear call to the listview I also called another function simulating the CollectionChanged event.
Create the new event like function...
private void myListViewControl_CollectionChanged(object sender, NotifyCollectionChangedEventArgs e)
{
//The projects ListView has been changed
switch (e.Action)
{
case NotifyCollectionChangedAction.Add:
MessageBox.Show("An Item Has Been Added To The ListView!");
break;
case NotifyCollectionChangedAction.Reset:
MessageBox.Show("The ListView Has Been Cleared!");
break;
}
}
Add an item to the ListView elsewhere...
ListViewItem lvi = new ListViewItem("ListViewItem 1");
lvi.SubItems.Add("My Subitem 1");
myListViewControl.Items.Add(lvi);
myListViewControl_CollectionChanged(myListViewControl, new NotifyCollectionChangedEventArgs(NotifyCollectionChangedAction.Add, lvi, lvi.Index));
Clear the ListView elsewhere...
myListViewControl.Items.Clear();
myListViewControl_CollectionChanged(myListViewControl, new NotifyCollectionChangedEventArgs(NotifyCollectionChangedAction.Reset));
