Last item in the paragraph is either

- the last item before the next paragraph (IsParaStart is true for the first

item of the next paragraph, and the last item of this paragraph is the

previous item)

or

- the last document item (ItemCount-1), if this is a last paragraph

For example, in the paragraph started from FirstItemNo:

LastItemNo := FirstItemNo;

while (LastItemNo+1<rv.ItemCount) and not rv.IsParaStart(LastItemNo+1) do

  inc(LastItemNo);

You must call Format after calling DeleteItems (and ClearUndo, because this

operation damages undo/redo buffers).

(DeleteLines is an old name of DeleteItems; if you use old version of the

component, please update).

You must be careful when using DeleteItems.

Please read "Valid Documents" topic in the help file.

There is alternative way to delete items: select them (SetSelectionBounds)

and call DeleteSelection. This operation can be undone/redone.

Sorry, I do not understand this question. Items are always indexed from 0 to

ItemCount-1.
