Hello programmers!
I'm building a GridTableView code, which is to show the detail of each record in a RadGridView.
To establish the relationship between registration and the detail table, I add a GridRelationFields keys thereof.
When I run the program (developed in aspx), whenever I click on to expand, I get the error I show in the picture:
Help!!!
