Bind the data to the GridView.?

Short answer: Example: protected void Page_Load(object sender, EventArgs e) {

Example code

if (!IsPostBack)
{ SqlConnection connection = new SqlConnection(connectionString); SqlDataAdapter adapter = new SqlDataAdapter("SELECT CustomerID, CustomerName FROM Customers", connection); DataTable dataTable = new DataTable(); adapter.Fill(dataTable); GridView1.DataSource = dataTable; GridView1.DataBind(); }
} Here, GridView1 is bound to the data returned from the SQL query (SELECT CustomerID, CustomerName FROM Customers), and the DataBind() method displays it in the grid.

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.
