    private AutoCompleteStringCollection sc0 = null; // Column 0
    private AutoCompleteStringCollection sc1 = null; // Column 1

    public Form1()
    {
        InitializeComponent();
    }

    private void Form1_Load(object sender, EventArgs e)
    {
        // Load Data
        sc0 = new AutoCompleteStringCollection() { "00", "000", "00000" };
        sc1 = new AutoCompleteStringCollection() { "11", "111", "11111" };
    }

    private void dataGridView1_EditingControlShowing(object sender, DataGridViewEditingControlShowingEventArgs e)
    {
        if (e.Control is DataGridViewTextBoxEditingControl)
        {
            var tec = (e.Control as DataGridViewTextBoxEditingControl);
            tec.AutoCompleteMode = AutoCompleteMode.SuggestAppend;
            tec.AutoCompleteSource = AutoCompleteSource.CustomSource;

            switch (dataGridView1.CurrentCell.ColumnIndex)
            {

use CellValueChanged or CellLeave event of DataGridview to check into the DB..

you can write code like..
add event to datagridview

C#

Datagridview1.CellValueChanged += new DataGridViewCellEventHandler(Datagridview1_CellLeave);

then Write your logic in the method you mentioned in the event..

C#

void Datagridview1_CellLeave(object sender, DataGridViewCellEventArgs e)
       {
           // your logic here

       }
