Getting available (empty) slots in container?

How can I get the available slots in a container/inventory and then lock them.

 

This one should lead to forward to an own solution:

Code:

// ItemContainer
public bool IsFull()
{
return this.itemList.Count >= this.capacity;
}

Also the container flags can solve lock needs:

Code:

// ItemContainer.Flag
public const ItemContainer.Flag IsLocked = 16;

 

Is it possible to get the slot number which is empty then only lock that slot?

 

Nope..you cannot lock specific slots..you can only re-arrange items and limit the slots afterwards...then the visual "free" are locked.
