I am using Embarcadero® RAD Studio 10 Seattle Version 23.0.20618.2753
To make column read-only I used
Grid_All_Party.Columns[2].ReadOnly := True;
and
to make cell read-only I used
Grid_All_Party.ReadOnlys[1,0] := True;
but how to make all cells of grid read-only without using the below code personally for all columns.
Grid_Name.Columns[column_number].ReadOnly := True;
