    <p>Our application uses the MonoDevelop.Components.Docking framework in our Windows application. We last updated to the latest version in November 2010. I have come across some interesting behavior that occurs in the following situation:</p> <ul> <li><p>Press the auto hide button of the first panel in a DockGroupType.Tabbed ParentGroup</p></li> <li><p>Hold mouse over collapsed panel until it expands</p></li> <li><p>Drag panel into center of the tabbed group (back to original spot) and drop</p></li> </ul> <p>At this point the panel resizes to the size of the blue rectangle that showed where the panel would be dropped, and then undocks from the main window to float at that size. This only happens on the first item in a tabbed group. I found a commented out section of code in DockGroupItem.cs (line 112, GetDockTarget(..)) that seems as though it might deal with this. However, it references a DockPosition type that is not defined, CenterAfter. The method is below, with the commented out portion in bold:</p> <pre><code>public bool GetDockTarget (DockItem item, int px, int py, Gdk.Rectangle rect, out DockDelegate dockDelegate, out Gdk.Rectangle outrect) { dockDelegate = null; if (item != this.item &amp;&amp; this.item.Visible &amp;&amp; rect.Contains (px,py)) { int xdockMargin = (int) ((double)rect.Width * (1.0 - DockFrame.ItemDockCenterArea)) / 2; int ydockMargin = (int) ((double)rect.Height * (1.0 - DockFrame.ItemDockCenterArea)) / 2; DockPosition pos; /* if (ParentGroup.Type == DockGroupType.Tabbed) { rect = new Gdk.Rectangle (rect.X + xdockMargin, rect.Y + ydockMargin,rect.Width - xdockMargin*2, rect.Height - ydockMargin*2); pos = DockPosition.CenterAfter; } */ if (px &lt;= rect.X + xdockMargin &amp;&amp; ParentGroup.Type != DockGroupType.Horizontal) { outrect = new Gdk.Rectangle (rect.X, rect.Y, xdockMargin, rect.Height); pos = DockPosition.Left; } else if (px &gt;= rect.Right - xdockMargin &amp;&amp; ParentGroup.Type != DockGroupType.Horizontal) { outrect = new Gdk.Rectangle (rect.Right - xdockMargin, rect.Y, xdockMargin, rect.Height); pos = DockPosition.Right; } else if (py &lt;= rect.Y + ydockMargin &amp;&amp; ParentGroup.Type != DockGroupType.Vertical) { outrect = new Gdk.Rectangle (rect.X, rect.Y, rect.Width, ydockMargin); pos = DockPosition.Top; } else if (py &gt;= rect.Bottom - ydockMargin &amp;&amp; ParentGroup.Type != DockGroupType.Vertical) { outrect = new Gdk.Rectangle (rect.X, rect.Bottom - ydockMargin, rect.Width, ydockMargin); pos = DockPosition.Bottom; } else { outrect = new Gdk.Rectangle (rect.X + xdockMargin, rect.Y + ydockMargin, rect.Width - xdockMargin*2, rect.Height - ydockMargin*2); pos = DockPosition.Center; } dockDelegate = delegate (DockItem dit) { DockGroupItem it = ParentGroup.AddObject (dit, pos, Id); it.SetVisible (true); ParentGroup.FocusItem (it); }; return true; } outrect = Gdk.Rectangle.Zero; return false; } </code></pre> <p>I have tried a few small things, but nothing as affected the behavior so far. Any ideas on what I could edit to get this working properly? Thanks!</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.
