What is the difference between data-bound controls and manually bound controls in ADO.NET?

Short answer: Data-Bound Controls: These controls automatically bind to a data source, such as a DataSet or DataTable, and update the UI when the data changes. Examples include GridView, DropDownList, and ListBox. Manually Bound Controls: These controls do not automatically update when the data changes. You need to manually manage data binding, such as updating the display values when the data changes.

Real-world example (ShopNest)

ShopNest’s reporting job still uses ADO.NET for a heavy SQL query where raw performance and stored procedures matter more than EF convenience.

Say this in the interview

1. Define — one clear sentence (the short answer above).
2. Example — relate it to a project like ShopNest or your real work.
3. Trade-off — when you would not use it.
