I think there is a misunderstanding about the nature of column types when it comes to particular column type called readonly (ro).
Readonly is a behavioral attribute of a column and shouldn’t be mixed with other data types types like string, price, tree,date, numerical …etc.
So again, how can we have a column of particular type and is readonly at the same time?
How can I define a grid column that is of type 'price' and i
a) It can be done by creating new excell type.
b) it can be done by using ron column with formatting
c) It can be done by custom event
if (ind == INDEX ) return false;
where INDEX - index of column which need to be switched to readonly.
>>Readonly is a behavioral attribute of a column and shouldn’t be mixed
Basically it is correct, but in current design excell control all aspects of data editing|rendering, and we can’t just jump to new approach because of backward compatibility issues.
