Problem
What is the fastest way to determine the last filled row in a column?
Cause
Action
The fastest way to determine this is to prepare the information when the grid is filled. You could maintain an array of high-water marks where you store the last column for each column.
Every time you or the user changes cells in the grid, StoreStyleRowCol() is called. So, you should override StoreStyleRowCol() and increase the high-water-mark for the specific column if necessary.
Take care if rows are removed or inserted:
- When rows are removed StoreRemoveRows() is called.
- When removing rows is undone StoreInsertRows() is called.
Override these two methods and adjust the high-water-mark.
