Can somone tell me why? thanks</p> <p>here is my whole code for the form</p> <pre><code>public partial class inicio : Form { private string ConnectionString = "Data Source=localhost\\sqlexpress;Initial Catalog=data.mdf;Integrated Security=SSPI;"; //private string ConnectionString = "Server=.\\SQLExpress;AttachDbFilename=|DataDirectory|\\data\\data_data.mdf.mdf; Database=data.mdf;Trusted_Connection=Yes;"; private ISessionFactory sessionFactory; List&lt;Material&gt; mater = new List&lt;Material&gt;(); List&lt;Salarios&gt; salar = new List&lt;Salarios&gt;(); IBindingList mind = new BindingList&lt;Salarios&gt;(); Productos prod; public inicio() { InitializeComponent(); sessionFactory = nhn.BusinessObjects.Initialize.CreateSessionFactory(ConnectionString); dgvMaterial.DataSource = mater; } private void materialToolStripMenuItem_Click(object sender, EventArgs e) { Catalogos.frmMaterial material = new costeos.Catalogos.frmMaterial(ConnectionString); material.ShowDialog(this); material.Dispose(); } private void salariosToolStripMenuItem_Click(object sender, EventArgs e) { Catalogos.frmSalarios salarios = new costeos.Catalogos.frmSalarios(ConnectionString); salarios.ShowDialog(this); salarios.Dispose(); } private void agregarToolStripMenuItem_Click(object sender, EventArgs e) { Catalogos.frmAddRemuneraciones rem = new costeos.Catalogos.frmAddRemuneraciones(ConnectionString); rem.ShowDialog(this); rem.Dispose(); } private void agregarToolStripMenuItem1_Click(object sender, EventArgs e) { Catalogos.frmAddAdmin adm = new costeos.Catalogos.frmAddAdmin(ConnectionString); adm.ShowDialog(this); adm.Dispose(); } private void agregarToolStripMenuItem2_Click(object sender, EventArgs e) { Catalogos.frmAddInsumosInd insumos = new costeos.Catalogos.frmAddInsumosInd(ConnectionString); insumos.ShowDialog(this); insumos.Dispose(); } private void txt_KeyPress(object sender, KeyPressEventArgs e) { if (char.IsDigit(e.KeyChar) || char.IsPunctuation(e.KeyChar) || char.IsControl(e.KeyChar)) { e.Handled = false; } else { e.Handled = true; } } private void inicio_Load(object sender, EventArgs e) { LlenaCampos(); } private void LlenaCampos() { using (var session = sessionFactory.OpenSession()) { using (var transaction = session.BeginTransaction()) { var mat = session.CreateCriteria(typeof(Material)) .List&lt;Material&gt;(); var sal = session.CreateCriteria(typeof(Salarios)) .List&lt;Salarios&gt;(); transaction.Commit(); cmbMaterial.DataSource = mat; cmbMaterial.DisplayMember = "Nombre"; cmbSalarios.DataSource = sal; cmbSalarios.DisplayMember = "Nombre"; cmbMIndirecta.DataSource = sal; cmbMIndirecta.DisplayMember = "Nombre"; } } } private void btnAddMaterial_Click(object sender, EventArgs e) { materialBindingSource.DataSource = null; //dgvMaterial.DataSource = null; mater.Add((Material)cmbMaterial.SelectedValue); //dgvMaterial.DataSource = mater; dgvMaterial.DataSource = materialBindingSource; materialBindingSource.DataSource = mater; materialBindingSource.ResetBindings(false); } private void button2_Click(object sender, EventArgs e) { dgvSalarios.DataSource = null; salar.Add((Salarios)cmbSalarios.SelectedValue); dgvSalarios.DataSource = salar; } private void button3_Click(object sender, EventArgs e) { dgvMIndirecta.DataSource = null; mind.Add((Salarios)cmbMIndirecta.SelectedValue); dgvMIndirecta.DataSource = mind; } private void button1_Click(object sender, EventArgs e) { using (var session = sessionFactory.OpenSession()) { using (var transaction = session.BeginTransaction()) { if (prod == null) { prod = new Productos { CargasTurno = float.Parse(txtCargasTurno.Text), CavidadesMolde = int.Parse(txtCavidadesMolde.Text), Clave = txtClave.Text, Comentarios = txtComentarios.Text, MezclasTurno = float.Parse(txtMezclasTurno.Text), Moldes = int.Parse(txtMoldes.Text), Nombre = txtNombre.Text, Peso = float.Parse(txtPesoTotal.Text), TotalPza = int.Parse(txtPzasTotales.Text), Turnos = int.Parse(txtTurnos.Text) }; session.Save(prod); transaction.Commit(); } foreach (DataGridViewRow dr in dgvMaterial.Rows) { Material m = dr.DataBoundItem as Material; m.Materiales PMaterial mat = new PMaterial { Material = dr.DataBoundItem as Material, Cantidad = float.Parse(dr.Cells["Cantidad"].Value.ToString()), Fecha = DateTime.Now, Producto = prod }; session.Save(mat); } transaction.Commit(); session.Close(); } } } } </code></pre> <p>}</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
