    <p>I just have a quick question. Whenever I Insert something into my C# interface (which is connected to a SQL database), I get the message of "Saved Data" that I programmed (and it saves the data in the database), but my DataGridView doesn't updates unless I close the application and run it again. </p> <p>My code is: </p> <pre><code>private void frmCatalogoMunicipios_Load(object sender, EventArgs e) { cmd.Connection = conexion; } private void frmCatalogoMunicipios_Shown(object sender, EventArgs e) { CargaEstados(); CargaDataGridView(); } private void CargaEstados() { conexion.Open(); txtNomMun.Focus(); try { DataSet ds = new DataSet(); MySqlDataAdapter da = new MySqlDataAdapter("SELECT cveestado, nombre FROM tbestados", conexion); da.Fill(ds, "FillDropDown"); cbEstado.DisplayMember = "Nombre"; cbEstado.ValueMember = "CveEstado"; cbEstado.DataSource = ds.Tables["FillDropDown"]; conexion.Close(); } catch (Exception ex) { MessageBox.Show(ex.Message, Application.ProductName, MessageBoxButtons.OK, MessageBoxIcon.Error); } } private void CargaDataGridView() { conexion.Open(); try { cmd.CommandText = "SELECT m.cvemunicipio, m.nombre AS NombreA, e.nombre AS NombreB FROM tbMunicipios m INNER JOIN tbEstados e ON m.CveEstado = e.CVeEstado"; rd = cmd.ExecuteReader(); while (rd.Read()) { this.dataGridView1.Rows.Add(rd.GetValue(0), rd.GetValue(1), rd.GetValue(2)); } conexion.Close(); } catch (Exception ex) { MessageBox.Show(ex.Message, Application.ProductName, MessageBoxButtons.OK, MessageBoxIcon.Error); } } conexion.Open(); try { cmd.CommandText = "insert into tbmunicipios (nombre, cveestado) values ('" + txtNomMun.Text + "', '" + cbEstado.SelectedValue.ToString() + "')"; cmd.ExecuteNonQuery(); cmd.Clone(); MessageBox.Show("Datos Guardados", "Mensaje"); conexion.Close(); Nuevo(); } catch (Exception ex) { MessageBox.Show(ex.Message, Application.ProductName, MessageBoxButtons.OK, MessageBoxIcon.Error); } </code></pre> <p><strong>EDIT</strong></p> <p>I found the answer myself: like @Obama said. I have to call CargarDataGridView(), BUT before that i deleted all my rows with dataGridView1.Rows.Clear();</p> <p>So, my final code is:</p> <pre><code> conexion.Open(); try { cmd.CommandText = "insert into tbmunicipios (nombre, cveestado) values ('" + txtNomMun.Text + "', '" + cbEstado.SelectedValue.ToString() + "')"; cmd.ExecuteNonQuery(); cmd.Clone(); MessageBox.Show("Datos Guardados", "Mensaje"); conexion.Close(); dataGridView1.Rows.Clear(); CargaDataGridView(); Nuevo(); } catch (Exception ex) { MessageBox.Show(ex.Message, Application.ProductName, MessageBoxButtons.OK, MessageBoxIcon.Error); } </code></pre>

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.

SQuiL has stopped working due to an internal error.

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