    <p>pls, try putting the code below in your button's on click event handler:</p> <pre><code> DataGridCell cell = GetCell(1, 0); if (cell != null) { cell.Focus(); yourDataGrid.BeginEdit(); } </code></pre> <p>below is implementation for the GetCell method taken from here <a href="http://social.msdn.microsoft.com/forums/en-US/wpf/thread/63974f4f-d9ee-45af-8499-42f29cbc22ae" rel="noreferrer">Grabing controls from a DataGrid</a></p> <pre><code>public DataGridCell GetCell(int row, int column) { DataGridRow rowContainer = GetRow(row); if (rowContainer != null) { DataGridCellsPresenter presenter = GetVisualChild&lt;DataGridCellsPresenter&gt;(rowContainer); // try to get the cell but it may possibly be virtualized DataGridCell cell = (DataGridCell)presenter.ItemContainerGenerator.ContainerFromIndex(column); if (cell == null) { // now try to bring into view and retreive the cell gridPersons.ScrollIntoView(rowContainer, gridPersons.Columns[column]); cell = (DataGridCell)presenter.ItemContainerGenerator.ContainerFromIndex(column); } return cell; } return null; } public DataGridRow GetRow(int index) { DataGridRow row = (DataGridRow)gridPersons.ItemContainerGenerator.ContainerFromIndex(index); if (row == null) { // may be virtualized, bring into view and try again gridPersons.ScrollIntoView(gridPersons.Items[index]); row = (DataGridRow)gridPersons.ItemContainerGenerator.ContainerFromIndex(index); } return row; } static T GetVisualChild&lt;T&gt;(Visual parent) where T : Visual { T child = default(T); int numVisuals = VisualTreeHelper.GetChildrenCount(parent); for (int i = 0; i &lt; numVisuals; i++) { Visual v = (Visual)VisualTreeHelper.GetChild(parent, i); child = v as T; if (child == null) { child = GetVisualChild&lt;T&gt;(v); } if (child != null) { break; } } return child; } </code></pre> <p>hope this helps, regards</p>

    2. COI ran into the same problem. This code doesn't work for me directly. However, it works only if I call the first few lines from Dispatcher.BeginInvoke, like this: Dispatcher.BeginInvoke(DispatcherPriority.Render, new Action(() => StartEditCurrentCell()));

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).
