Changing Row/Column line colors of cells in TGrid

[Squall_FF8 1]

Hey Guys,

I have a TGrid in my project. It works great, but I want to change the colors of row/columns lines?
How I can do that in FMX for Delphi 12.2?

Quick response, use OnDrawColunmnCell event.

You can see also how I manage a  Data Grid CopyToClipBoard GitHub link.

 

I don't remember if in that repository I use TStyleBook, on a French forum I worked this

Thank you Serge_G!

Correct me if I'm wrong, but  looking in your code on Github and the French forum, I have to implement it by hooking OnDrawColunmnCell. If I want to manipulate:
- the background color of cells:, FillRect
- the border color of cells: FillStroke

Hooking !? no except if you want to export data for selected cells (wich was my goal).
You only have to use OnDrawColumnCell event like in ExportStringGridMain.pas, (procedure TFormTest.StringGrid1DrawColumnCell )

Sorry,, by hooking I mean using OnDrawColunmnCell  🙂
