I have DataGridView with predefined columns: id, name, phone.

In SQL Server database, I have a Users table with these columns:

user_id, user_name, user_phone

Select data from Users table :

SqlConnection con = new SqlConnection(connectionString);
SqlDataAdapter ad = new SqlDataAdapter("SELECT * FROM users", con);

DataTable dt = new DataTable();
con.Open();
ad.Fill(dt);

DataGridView1.DataSource = dt;
con.Close();

This code works fine and shows all rows. But the main problem is DataTable also adds the Users table columns to the DataGridView.

DataGridView output:

id | name | phone | user_id | user_name | user_phone

How to add rows from DataTable to specific pre-defined columns?

And another question is how to prevent DataTable to add SQL Server table columns to DataGridView?

Thank you.

  • Change your query : "SELECT id as ID, name as PERSON, phone , user_id as UID, user_name as UNAME, user_phone FROM users" – jdweng Jul 12 '22 at 09:04

Add the columns to your DataGridView in the designer and set the DataPropertyName property of each column to the data source column name you want it to bind to. In code, set the AutoGenerateColumns property to False before setting the DataSource.
