Another thing. I want to show/hide some columns in runtime. Somehow i'm not succeeding in it

Grid->GridLinks->SafeCommaText=Str; //here I set the column ordering (data is read into Str from INI file)
//NB! There is a problem, when I hide some columns, then they are not saved into INI and I dont' have access to them anymore when I want to set them back to visible.
for(i=0;i<Grid->GridFieldCount;i++)
{ if(Grid->GridFields[i]->FieldName=="REG" || Grid->GridFields[i]->FieldName=="CREF" )
Grid->GridFields[i]->Visible=false;
}

This removes only first field, because the indexing changes as soon as I set one field unvisible and later I cant get back to this anymore.
There must be some other, more normal way to do manipulate the grid (or dataset)

Hi,

To be more precise: TIB_Column.FieldNo *always* returns the 0-based
field number as it is in the SQL, regardless of any ordering you may
have specified in TIB_Query.FieldsIndex.

Grtz,
