Call the DataBind() method to bind the data to the GridView.?

Short answer: Example: SqlDataAdapter adapter = new SqlDataAdapter("SELECT * FROM Customers", connection); DataTable dt = new DataTable(); adapter.Fill(dt); GridView1.DataSource = dt; GridView1.DataBind();

Example code

SqlDataAdapter adapter = new SqlDataAdapter("SELECT * FROM Customers", connection); DataTable dt = new DataTable(); adapter.Fill(dt); GridView1.DataSource = dt; GridView1.DataBind();

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.
