    1. COMeda, Thank you so much for the above code. I have updated my code with the above logic. Everything looks good except I now have two issues before I can run the code. The error is "Type or namespace 'SQLCommand' could not be found. Are you missing a user directive or an assembly reference?" The same message is also displaying for the SQLAdaptor line. Including this namespace at the top of the page resolved this error for the SQLConnection: <%@ Import Namespace="System.Data.SqlClient" %> How do I resolve these other two errors? This did not happen yesterday.

    2. COI resolved the assembly references but get this error when the page tries to load: Both DataSource and DataSourceID are defined on 'gvAuthors'. Remove one definition." I double-checked and everything on my page is the same as the code you provided. What is the best way to resolve this error?

Guidance
A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
