learn more about DataGridView.
here we are going to add new rows after every button click. so for that we need to create a function which holds columns and rows which holds data in DataGridView.
Hyper Links contains information from docs.microsoft.com
private void button1_Click(object sender, EventArgs e)
{
addRow(textBox1.Text.ToString(),Convert.ToInt32(textBox2.Text));
}
private void addRow(string name,int roll)
{
dataGridView1.Columns.Add("Name","Name");
dataGridView1.Columns.Add("Roll", "Roll");
object[] data = { name, roll };
dataGridView1.Rows.Add(data);
}
Check out new one Here: AutoCompleteTextBox with C#
before copy paste code make sure that, you have used using System.Data.SqlClient; in your code
below code is for SQL DataBase
Hyper Links contains information from docs.microsoft.com
void autocomplete_txt()
{
textBox1.AutoCompleteMode = AutoCompleteMode.Suggest;
textBox1.AutoCompleteSource = AutoCompleteSource.CustomSource;
AutoCompleteStringCollection coll_obj = new AutoCompleteStringCollection();
SqlConnection conn = new SqlConnection(@"Data Source=(LocalDB)\MSSQLLocalDB;AttachDbFilename=C:\USERS\ANIKET\DOCUMENTS\JERRYINDIA.MDF;Integrated Security=True;Connect Timeout=30");
conn.Open();
SqlCommand cmd = new SqlCommand("select * from bazaar", conn);
SqlDataReader reader = cmd.ExecuteReader();
//this is for product name
int itemCodeOrdinal = reader.GetOrdinal("product_name");
while(reader.Read())
{
string prd_nm = reader.GetString(itemCodeOrdinal);
coll_obj.Add(prd_nm);
}
textBox1.AutoCompleteCustomSource = coll_obj;
