    text
    copied!<p>I have a DataGrid defined with WPF Toolkit. The CellEditingTemplate of this DataGrid is associated at runtime with a custom function that build a FrameworkElementFactory element.</p> <p>Now I have to access to control that is inserted inside DataTemplate of CellEditingTempleta, but I do not know how to do.</p> <p>On web I found a useful ListView Helper...</p> <pre><code>public static class ListViewHelper { public static FrameworkElement GetElementFromCellTemplate(ListView listView, Int32 column, Int32 row, String name) { if (row &gt;= listView.Items.Count || row &lt; 0) { throw new ArgumentOutOfRangeException("row"); } GridView gridView = listView.View as GridView; if (gridView == null) { return null; } if (column &gt;= gridView.Columns.Count || column &lt; 0) { throw new ArgumentOutOfRangeException("column"); } ListViewItem item = listView.ItemContainerGenerator.ContainerFromItem(listView.Items[row]) as ListViewItem; if (item != null) { GridViewRowPresenter rowPresenter = GetFrameworkElementByName&lt;GridViewRowPresenter&gt;(item); if (rowPresenter != null) { ContentPresenter templatedParent = VisualTreeHelper.GetChild(rowPresenter, column) as ContentPresenter; DataTemplate dataTemplate = gridView.Columns[column].CellTemplate; if (dataTemplate != null &amp;&amp; templatedParent != null) { return dataTemplate.FindName(name, templatedParent) as FrameworkElement; } } } return null; } private static T GetFrameworkElementByName&lt;T&gt;(FrameworkElement referenceElement) where T : FrameworkElement { FrameworkElement child = null; for (Int32 i = 0; i &lt; VisualTreeHelper.GetChildrenCount(referenceElement); i++) { child = VisualTreeHelper.GetChild(referenceElement, i) as FrameworkElement; System.Diagnostics.Debug.WriteLine(child); if (child != null &amp;&amp; child.GetType() == typeof(T)) { break; } else if (child != null) { child = GetFrameworkElementByName&lt;T&gt;(child); if (child != null &amp;&amp; child.GetType() == typeof(T)) { break; } } } return child as T; } } </code></pre> <p>this code work with the ListView object but not with the DataGrid object.</p> <p>How can use something like this in DataGrid?</p>
