The VisibleItemCount property counts the number of visible items in the list. For instance, you can use the VisibleItemCount property to get the number the control displays once the user applies a filter.

The VisibleItemCount property returns a value as explained bellow:

• 0, the control displays/contains no items, and no filter is applied to any column
• -1, the control displays no items, and there is a filter applied ( no match found )
• positive number, indicates the number of visible items, and the control has no filter applied to any column
• negative number, the absolute value munus 1, indicates the number of visible items, and there is a filter applied ( match found )

 The VisibleCount property retrieves the number of items being displayed in the control's client area. Use  FirstVisibleItem and NextVisibleItem properties to determine the items being displayed in the control's client area. Use the IsItemVisible property to check whether an item fits the control's client area. Use the ItemCount property to count the items in the control. Use the ChildCount property to count the child items
