    <p>I arrived on this by trial and error, so long ass you are using an ItemsSource data source it should work fine. It should work with virtual rows and causes only a brief visual pause and it switches over (this seems mainly down to column autogeneration so can be avoided). </p> <p>As hacks go it has the advantage of simplicity and the use of mechanics which are not expected to change. </p> <p>The heuristic on user triggering of the action might be improved but it has not failed on me yet.</p> <pre><code>using Microsoft.Windows.Controls; using Microsoft.Windows.Controls.Primitives; public static class DataGridExtensions { public static void LinkRowHeightsToUserChange(this DataGrid dataGrid) { double? heightToApply = null; bool userTriggered = false; if (dataGrid.RowHeaderStyle == null) dataGrid.RowHeaderStyle = new Style(typeof(DataGridRowHeader)); if (dataGrid.RowStyle == null) dataGrid.RowStyle = new Style(typeof(DataGridRow)); dataGrid.RowStyle.Setters.Add(new EventSetter() { Event = DataGridRow.SizeChangedEvent, Handler = new SizeChangedEventHandler((r, sizeArgs) =&gt; { if (userTriggered &amp;&amp; sizeArgs.HeightChanged) heightToApply = sizeArgs.NewSize.Height; }) }); dataGrid.RowHeaderStyle.Setters.Add(new EventSetter() { Event = DataGridRowHeader.PreviewMouseDownEvent, Handler = new MouseButtonEventHandler( (rh,e) =&gt; userTriggered = true) }); dataGrid.RowHeaderStyle.Setters.Add(new EventSetter() { Event = DataGridRowHeader.MouseLeaveEvent, Handler = new MouseEventHandler((o, mouseArgs) =&gt; { if (heightToApply.HasValue) { userTriggered = false; var itemsSource = dataGrid.ItemsSource; dataGrid.ItemsSource = null; dataGrid.RowHeight = heightToApply.Value; dataGrid.ItemsSource = itemsSource; heightToApply = null; } }) }); } </code></pre>

    1. COthis works, although it is very slow when virtualization is on.

    2. COsorry, meant when column virtualization is off.., if we turned it on, we couldnt scroll horizontally, but the rows did resize nicely.

    3. COYeah, I like that you only pay for the feature significantly when someone actually resizes but it is costly. You can probably cache the columns in some way, drop the source and recreate it without regenerating the columns.

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).
