grvCustomer.Visible = true;

grvCustomer.DataSource = dt;

MessageBox.Show("No customer found with this ID. " +
"Please try again.", "Customer Not Found");
grvCustomer.Visible = false;

As I understand you would like to select the newly added row on the bottom of the grid.

Optionally you can clear the previous selection if any exists. Set the selected property of the last row to true. And again optionally scroll grid's view to the last row of the grid, in case it is outside of the visible grid's region.

var lastRowIndex = this.grvCustomer.Rows.Count - 1;

this.grvCustomer.Rows[lastRowIndex].Selected = true;
this.grvCustomer.FirstDisplayedScrollingRowIndex = lastRowIndex;


In case the modified row is not known, you have to enumerate through the rows collection and find the value of the cell under the customer ID column that match the value of the dialog form.

foreach (DataGridViewRow row in this.grvCustomer.Rows)
    if (row.Cells["CustomerID"].Value.ToString() == addCustomerForm.customer.CustomerID.ToString())
        row.Selected = true;
