Solution 3

C#

cmd.CommandText = "SELECT CMC, [Site Name], [Phone Number], Zip_Code FROM site Where Zip_Code='" + Zipcode.Text + "'";

Never build an SQL query by concatenating with user inputs, it is named "SQL injection", it is dangerous for your database and error prone.
A single quote in a name and your program crash. If a user input like "Brian O'Conner" can crash your app, it is an SQL injection vulnerability.

This is my solution

private void Crt_clck_Click(object sender, EventArgs e)
{

{
con.Open();
SqlCommand cmd = con.CreateCommand();
cmd.CommandType = CommandType.Text;
cmd.CommandText = "SELECT CMC, [Site Name], [Phone Number], Zip_Code FROM site Where Zip_Code='" + Zipcode.Text + "'";
cmd.ExecuteNonQuery();
DataTable dt = new DataTable();
SqlDataAdapter da = new SqlDataAdapter(cmd);
da.Fill(dt);
dataGridView1.DataSource = dt;
con.Close();
}

Solution 1

You can use a DataView, like this:

DataView dv = new DataView(table);
dv.RowFilter = "id = 1"; // query

See: DataView RowFilter Syntax [C#][^]
