Please say me a method that used in populate listview and i search in documentation.

If i have doubt, question in the forum.

You could pass the parameter in the Requery method of the ListView:

MyListView.Requery(myCoolParameter);

But, as I found out over time, it is better to pass the parameter in the ListPopulating event of the ListView (from docs using VB):

Then, whenever you need to refresh the ListView control, it is a simple call to its Requery method:

MyListView.Requery();

No need to remember to pass a parameter since it is handled in the event.  Good stuff.  A "set it and forget it" type of approach.
