Hi Steve…

Obvously you are busy these days…

if you’ll find some time to help

here is a tricky problem:

I’d like to modify the css of a table row

(I know how to do that) by a condition.

Usually the rows are swiched from odd to even.

I was wondering if it was possible to group

entries with the same Date by applying the same

background color.

Code: Select all

`[b]!!pseudocode[/b]

function css__tableRowClass(&$record){
    if ( $record->val(‘date’) == ‘$record->val(‘date’) of a previous record’ ){
        return ‘bgcolor of the previous entry with the same date’;
    }else return ‘’; }`

for this the function in the table delegate class

has to be aware of its own status “odd/even”

and as if this wasn’t complicated

enough, $record->val(‘date’) has to be compared to the

other rows…

mmhh…

I must confess I am not clever enough for that challenge

but maybe you are provoked by my dilettantism

thanks and cheers

Hi Martin,

This is a bit of a hack, but you could “hope” that this function is called once per row. You could then use a static variable to track the date of the previous row:

Code: Select all

function css__tableRowClass(&$record){     static $even = false;     static $prevDate = -1;     if ( $record->strval('date') != $prevDate ){         $prevDate = $record->strval('date');         $even = !$even;     }     return ($even?'even':'odd'); }

Or something along those lines.

Hi Steve

Thanks for the hack…

it was’nt working reliable out of the box but

i’ll experiment with the static variable to get this working

cheers
