Question

Using a textbox to search a value in a given datagridview column, the code below position the selected row on the column containing the text typed.

    private void textBox1_TextChanged(object sender, EventArgs e)
    {
        //if (Char.IsLetter(e.KeyChar))
        //{
            for (int i = 0; i < (productDataGridView.Rows.Count); i++)
            {

                if (productDataGridView.Rows[i].Cells[1].Value.ToString().StartsWith(textBox1.Text, true, CultureInfo.InvariantCulture))
                {
                    productDataGridView.FirstDisplayedCell = productDataGridView[1, i];
                    productDataGridView.CurrentRow.DefaultCellStyle.BackColor = System.Drawing.Color.Red;
                    return; // stop looping 
                }
            }
     }

The problem is that I cannot highlight or change the back color of the required row while typing in the textbox, any help please?

Tried this solution, this finally works like a charm:

            try
        {
            productDataGridView.ClearSelection();   //or restore rows backcolor to default
            for (int i = 0; i < (productDataGridView.Rows.Count); i++)
            {
                if (productDataGridView.Rows[i].Cells[1].Value.ToString().StartsWith(textBox1.Text, true, CultureInfo.InvariantCulture))
                {
                    productDataGridView.FirstDisplayedScrollingRowIndex = i;
                    productDataGridView.Rows[i].Selected = true; //It is also possible to color the row backgroud
                    return;
                }
            }
        }
        catch (Exception) 
        { 
        }
