Records sorting and pagination

Question

I have a datasource with 50 rows per page. The table has some 500 rows. I also have a grid on this datasource, and an action to sort the values when a header column is clicked.

By using api_datasource.setfilterorderby it works but ONLY in the shown page meaning that it sorts the 50 shown rows only. It doesn't sort the entire 500 rows.

I also tried to base the order by clause of the datasource on a parameter (order by is declared as :orderBy where :orderBy is the parameter), set this parameter to "my_column ASC" or "my_column DESC" and finally run the api_datasource.executequery to refresh the results. In this case it looks like the system ignores completelly the order by clause, even if the parameter has some value. I guess that it takes the order by clause as it was at design time and the parameter is not evaluated.

How can I sort the entire result set by re-executing the query with a new order by each time?

Thank you.

Hi Akis,

You can sort the entire result set by re-executing the query by setting the sortMode attribute of the grid column to be sorted as "ExecuteQuery";

<grid ...>
  <column ... sortMode="ExecuteQuery">
    ...
  </column>
</grid>

Kind Regards, Ibrahim
