Body
<p>This one has stumped me now for a little bit. I am creating a derived <code>System.Windows.Forms.DataGridView</code> control with some sensible default values. Now to make this clear they are simply default values and should be capable of being changed in the designer. As of right now I have the default values being set in the controls constructor:</p> <pre><code>using System.Drawing; using System.Windows.Forms; namespace TruckSmart.Controls { /// <summary> /// An implementation of a System.Windows.Forms.DataGridView with sensible default values. /// </summary> public class DataGrid : System.Windows.Forms.DataGridView { /// <summary> /// Initializes a new instance of the TruckSmart.Controls.DataGrid class. /// </summary> public DataGrid() { AllowUserToAddRows = false; AllowUserToDeleteRows = false; AllowUserToOrderColumns = false; AllowUserToResizeColumns = false; AllowUserToResizeRows = false; AutoGenerateColumns = false; AutoSizeColumnsMode = DataGridViewAutoSizeColumnsMode.DisplayedCells; AutoSizeRowsMode = DataGridViewAutoSizeRowsMode.DisplayedCells; BackgroundColor = SystemColors.Window; BorderStyle = BorderStyle.Fixed3D; ColumnHeadersBorderStyle = DataGridViewHeaderBorderStyle.None; Margin = new Padding(0); MultiSelect = false; ReadOnly = true; RowHeadersVisible = false; SelectionMode = DataGridViewSelectionMode.FullRowSelect; AlternatingRowsDefaultCellStyle = new DataGridViewCellStyle() { BackColor = Color.FromKnownColor(KnownColor.AliceBlue) }; ColumnHeadersDefaultCellStyle = new DataGridViewCellStyle() { WrapMode = DataGridViewTriState.False }; } } } </code></pre> <p>The main problem with using the constructor is that when I close my form designer in Visual Studio and re-open it the constructor is called again and any changes I made previously in the designer are reset. Is there a special place I should be putting these default values?</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.
