Save and Load contents TStringGrid

Question

I have a simple form containing TstringGrid with 2 columns, a TStringColumn and TCheckColumn added. I have seen many examples of saving the contents to file if the cells contain text or numbers. I have not seen any examples of saving with a TCheckColumn . I am assuming that I must check each CheckColumn cell, determine its state and assign a value that can be saved to file. Or maybe there is a more elegant way to do this.

As for sorting - again many examples using strings or numbers but none with TCheckColumn . I have HeaderClick enabled. On the TStringColumn I would like to sort Alphabetically - On the TCheckColumn - I would like checked items at the top of the column.

I am using Delphi 10.2.1 and will compile for Android.

Without saying you shouldn't start from here - I will just answer the specific questioN; To keep it simple, I would: Save: iterate through the rows and take the state of the checkboxes and prefix the string item with BoolToStr(theCheckValue)+':'+theContents of the string. Then save the stringList.

To Load: load into the stringList and then iterate and break the string apart using pos on the ':' and StrToBool the left portion, setting the checked item based on this. Not got an IDE up, so haven't tested, but that would be my approach as a bit of a hack.
