    <p>I have a datagridview with a filter for doing search. If I update the database and then reset the dgv to the datasource I lose my filter. I tried doing ResetBindings but that didn't help. If I close the form and reopen the changes are there, I'd just like it to happen in "real time". Any advice is appreciated.</p> <p>I have a dataset based on a SQL view. In this dataset there is a table based on this view. The datagridview is bound to this table. I have several controls including textboxes and combo boxes which are bound to columns in the dgv. I have a textbox which is used to search on the grid:</p> <pre><code>private void txtFilterString_TextChanged(object sender, EventArgs e) { ToolStripTextBox tb = (ToolStripTextBox)sender; DataView dv = tILEDataSet.vwTILEAdmin.DefaultView; vwTILEAdminBindingSource.Filter = string.Format(@"PdcProductName LIKE '%{0}%' OR LabelDescription LIKE '%{0}%' OR LabelProductName LIKE '%{0}%'", tb.Text.Trim().Replace("'", "''")); dataGridView1.Refresh(); } </code></pre> <p>After making changes to a row in the dgv by modifying one or more of the bound controls I save the changes, which update the table:</p> <pre><code>sql.Append(@"UPDATE [dbo].[LabeledProducts] SET [PdcProductName] = @pdcProd ,[LabelProductName] = @lblProd ,[LabelDescription] = @lblDesc ,[Power] = @pwr ,[Fabrication] = 0 ,[UL_File_Number] = '' ,[PrePrintedSerial] = 0 ,[ShowOrderOnLabel] = 0 ,[PrivateLabelLogoId] = @plid ,[AgencyImageId] = @aid ,[WireDiagConfigId] = @wid WHERE PdcProductName = '").Append(pdcProductName).Append("'"); using (SqlCommand command = new SqlCommand(sql.ToString(), printConfigTableAdapter.Connection)) { if (vwTILEAdminTableAdapter.Connection.State != ConnectionState.Open) vwTILEAdminTableAdapter.Connection.Open(); LabeledProductsDataTableAdapter.UpdateCommand = command; LabeledProductsDataTableAdapter.UpdateCommand.Parameters.AddWithValue("@pdcProd", txtPdcProdName.Text); LabeledProductsDataTableAdapter.UpdateCommand.Parameters.AddWithValue("@lblProd", txtLabeledProd.Text); LabeledProductsDataTableAdapter.UpdateCommand.Parameters.AddWithValue("@lblDesc", txtLabelDesc.Text); LabeledProductsDataTableAdapter.UpdateCommand.Parameters.AddWithValue("@pwr", txtPower.Text); // we need ulfilename and mod LabeledProductsDataTableAdapter.UpdateCommand.Parameters.AddWithValue("@plid", LogoId); LabeledProductsDataTableAdapter.UpdateCommand.Parameters.AddWithValue("@aid", AgencyId); LabeledProductsDataTableAdapter.UpdateCommand.Parameters.AddWithValue("@wid", WireId); DataTable dt = new DataTable(); int rowsAffected = LabeledProductsDataTableAdapter.Update(dt); rowsAffected = command.ExecuteNonQuery(); dataGridView1.Refresh(); //dataGridView1.DataSource = tILEDataSet.vwTILEAdmin; //this.vwTILEAdminBindingSource.ResetBindings(true); } </code></pre> <p>If I uncomment the line where I set the DataSource, I get a refreshed view, but the textbox used to generate the filter on the binding source no longer works, e.g. regardless of what I type in the textbox. The Text_Changed event does still get called, but the filter no longer has any affect on the contents of the dgv. </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.
