TRVStyleTemplateComboBox must include all styles.
But some of them may be hidden initially.
See https://www.trichview.com/help-actions/ ... styles.htm

As for the initial display, when the application starts, call
rvActionNew.ExecuteTarget(RichViewEdit);

This command associates the editor with an unsaved file, and (if RichViewEdit.UseStyleTemplates = True) applies rvActionNew.StyleTemplates to the empty document, and updates cmbStyles.

Please ...

Did you assign RichViewEdit.UseStyleTemplates = True?

When do you want to add styles?
If you want to define collections of styles for new documents, edit rvActionNew.StyleTemplates collection.

A general information about named styles in TRichView is here: https://www.trichview.com/forums ...

Change RichViewTextItemClass to RVItemFactory.TextItemClass.

The code supporting starting and ending codes in different cells is below.

This kind of selection (from the starting cell till the end of the row; then all cells in the rows between; then cells till the ending cell) is not natural for TRichViewEdit: TRichViewEdit selects cell that are inside the ...

The original code has a bug.
It's incorrect to compare tle1 and tle2.
If a new tle2 is created, tle1 is destroyed.
It is possible that the Delphi memory manager reuses a freed memory, so tle1 = tle2.

The comparison must be like this:

var ItemNoI, ItemNoF, OffsI, OffsF: Integer;
tle1, tle2 ...

For example, if the cells are (2, 2) and (3,3).
Should it clear the cells in the (2, 3) and (3, 2)?
Or should it clear all cels in the row after (2, 2), and all cells in the row before (3, 3)?

This code must do nothing is the words are in different cells.
The check "if tle1=tle2 then" is to ensure that the words are in the same cell.

The code for deleting content between two cells would be much more complicated.
What does "content between cells" mean? If the cells are in different rows ...

Sorry, it was not included in the last release.
But I've made these changes. If you want, I can send modified units to you by email.

1. Emojis are Unicode characters. When they are pasted in a VCL TRichView editor, they are displayed using a text color. Unfortunately, the text engine used by the VCL version of TRichView does not allow displaying color emojis. But the FireMonkey version (that uses either DirectX or Skia drawing ...

The main problem in this code is re-adding existing items. You take an existing item (using GetItem method) and add it in another place (using AddItemAsIs or AddItem).
You cannot do it. Items are owned by the document. If an item is inserted several times, when the document is freed, the item will ...

You can attach a test project here, or send it to email richviewgmailcom.
Please make a compliable project, as simple as possible.

Each cell initially has an empty text item.
Call Cell.Clear before Cell.AddNL.
