Inserttext into rich text

Post by mcperes » Thu Jan 04, 2018 10:54 pm

I want to insert items from a dbgrid into the text, I will use drag and drop, so far so good, I know how to do. The problem is that when using a data from a dbgrid I need to change the color of the line and in case the user deletes the dragged text, dbgrid needs to return the line to normal.
I thought of leaving a comment within the text dragged in rich text using {\ * \ annotdef ...} - it would contain a reference to the database field that I would read to update the gride and - if the user deletes the inserted text, the comment would be erased together - also allowing you to update the gride, but to make it right I would have to drag the text into the code at the rich text level, and I only saw the inserttext method that I do not think inserts at that text level.

The current version of TRichView does not support annotdef RTF code.
If you need to insert a field, you can use InsertStringTag. Encode some information in tag string, allowing to identify the grid cell.

See the example: Demos\DelphiUnicode\Assorted\Fields\LiveLink\Tables\

right, but when I insert fields in this way I can not export to rtf and then reopen and have access to the ids of those fields?

Unfortunately, RTF annotations and merge fields are not supported yet, so you can save all additional information only in RVF files.
