Hello,
You can specify path of detail page into 'Detail page path' property of custom table datagrid web part. There should be ID of record automatically passed to detail page in query string then. You will need to get the ID from query string and use it in where condition property of web part(s) that you are going to use to display detail of this particular record.
If you use ASPX templates, you can use following method to get data from query string:
QueryHelper.GetInteger("nameOfQueryStringParameter", 0);
If you use PortalEngine, you can use following macro directly in properties of web part: {%nameOfQueryStringParameter%}
Please see '
Appendix A - Macro expressions' section in Dev.Guide for more details.
Best Regards,
Martin Dobsicek
