Hello,
I have found a weird problem with detail tables. After assigning the correct datakeys to the tables I found that one of my detail tables was not working even though there was nothing wrong with the query nor the detail table structure.
After a bunch of trial and error I found that unless the datakey names are the same in the Master and Detail grids, detail grids will not query any data.
In my mind this is a bug as we can assign whatever datakey names we want in the DataKeys attribute. The grid should not be enforcing a foreign key naming constraint, while a lot of the time these will be the same some times they will not and in those cases the master/detail relationship within the RadGrid breaks and does not work properly.
Full disclosure, our Telerik version is so old no one knows what version it is and we don't have access to the source files anymore to find out. It is a good bet it is pre-2013.

Since every version comes with new features, bug fixes and improvements, we always recommend upgrading to a later or even latest version of the control. For more information check out the Old Versions Support Policy in UI for ASP.NET AJAX article.
Nevertheless, we could try and see if there is anything we can do in your case, and for that we would need to know the exact version. You can find it out without having access to the source files. Two of the most common ways are described in the following forum thread: How to know what version of telerik do i have?. Once the version is known, let us know and we think of a workaround that may help.
Kind regards,
Attila Antal
