Order Asc-Desc with master-detail relationship

Hi,
I'm not sure that I understand your question. What values do you want to sort?

valus in column 'Lavorazioni' (columun master-detail relationship)

Could you clarify a bit more?

There are no any values in this column, only links to the detail table.

yes, there is no value because this column is the result of master-detail relationship between two tables, phprunner don't create any column, so it's possible create a value to order this column....??

I'm not sure that I understand this question.

Do you want to create some random values and then use these values to sort records?

Hi,
unfortunately there is no easy way to add sort link for this column.

As workaround you can sort records in your main SQL query on the Edit SQL query tab.

Here is a sample:

Tnx <img src='https://asprunner.com/forums/file.php?topicimage=1&fieldname=reply&id=43719&image=1&table=forumreplies' class='bbc_emoticon' alt=':lol:' />

i used
List page: before Sql query
function BeforeQueryList(&$strSQL,&$strWhereClause,&$strOrderBy)

{
$strOrderBy = ("order by detail_table_cnt2 DESC");

}
