How to implement data output to two dbgrids by Id?

Question

Delphi

They say that it is possible through Afterscroll, but did not understand how. Yes, I couldn't find anything. Or maybe some parametric query, maybe there are other options. Tell me please.

Answer 1

I will explain as I understand it:
The first table displays the data of the ADOQuery1 query, which has the id_realiz field.
The data of the ADOQuery2 query, which also has the id_realiz field, is displayed in the second table.
You want the second table to display only those records whose id_realiz field value matches the id_realiz field value of the selected row of the first table.
So?
If so, then this is the usual master - detail, and you googled something wrong. It is necessary:
​​1) ADOQuery2 query to add the id_realiz = :id_realiz condition to the where conditions
2) ADOQuery2 query to set the DataSource property equal to DataSource1
Everything. If you meant something else, please try again.
