You should handle the event when a value is changed in a ComboBox in a DataGridView cell. try this code which will fire the event of the selection in the comboBox in the dataGridView:

public Form1()
    {
        InitializeComponent();

        DataGridViewComboBoxColumn cmbcolumn = new DataGridViewComboBoxColumn();
        dataGridView2.EditingControlShowing += new DataGridViewEditingControlShowingEventHandler(dataGridView2_EditingControlShowing);


    }

    private void dataGridView2_EditingControlShowing(object sender, DataGridViewEditingControlShowingEventArgs e)
    {
        ComboBox combo = e.Control as ComboBox;
        if (combo != null)
        {
            combo.SelectedIndexChanged -= new EventHandler(ComboBox_SelectedIndexChanged);
            combo.SelectedIndexChanged += new EventHandler(ComboBox_SelectedIndexChanged);
        }
    }

    private void ComboBox_SelectedIndexChanged(object sender, EventArgs e)
    {
        ComboBox cb = (ComboBox)sender;
        string item = cb.Text;
        if (item == "Add")
        {
            Categorie cat = new Categorie();
            cat.Show();

        }
    }
