I suggest you do as follows:

Search Form:

public int SelectedId { get; set; }

private void searchdgv_CellDoubleClick(object sender, DataGridViewCellEventArgs e)
{
    this.rowIndex1 = e.RowIndex;
    this.SelectedId = Convert.ToInt32(this.searchdgv.Rows[this.rowIndex1].Cells["id"].Value);
    this.DialogResult = DialogResult.OK;
    this.Close();
}

Main form:

private void searchToolStripMenuItem_Click(object sender, EventArgs e)
{
    search form1 = new search();
    form1.ShowDialog();

    if (form1.DialogResult == DialogResult.OK)
    {
        int selectedId = form1.SelectedId;
        // Do whatever with selectedId...
    }
