WPF Datagrid: Checkbox and Button stackpanel

Question

Hello,

I coded in xaml.cs my datagrid with a single column of checkbox and button using factory and stackpanel. Right now I want to detect what column and row they are and if the checkbox ischecked = true. My column headers on datagrid are dynamic based on the dates range they chose

This is my sample code:

 int extra = 1;
                while (startDate < endDate.AddDays(1))
                {

                    string combo1 = "combo" + extra;

                    var col2 = new DataGridTemplateColumn();
                    string colname = startDate.ToShortDateString() + " [" + Utils.ToDateTime(startDate).ToString("ddd") + "]";
                    col2.Header = colname;
                    var template2 = new DataTemplate();
                    var sp = new FrameworkElementFactory(typeof(StackPanel));
                    sp.SetValue(StackPanel.OrientationProperty, Orientation.Horizontal);
                    var buttonfactoy = new FrameworkElementFactory(typeof(Button));

                    col2.CellTemplate = template2;
                    dgDaily.Columns.Add(col2);
                    dtDailyShift.Columns.Add(startDate.ToShortDateString(), typeof(string));

                    buttonfactoy.SetValue(Button.HeightProperty, 35.0);
                    buttonfactoy.SetValue(Button.ContentProperty, "CLICK FOR SHIFT");
                    buttonfactoy.SetValue(Button.MarginProperty, new Thickness(5));
                    buttonfactoy.SetResourceReference(Button.StyleProperty, "ButtonPrimary");
                    buttonfactoy.SetResourceReference(Button.HorizontalContentAlignmentProperty, HorizontalAlignment.Center);
                    // A column named 'System.Windows.Controls.DataGridTemplateColumn' already belongs to this DataTable.'
                    buttonfactoy.AddHandler(Button.ClickEvent, new RoutedEventHandler((o, f) => HandleColumnButtonClick(o, f)));

                    sp.AppendChild(buttonfactoy);



                    template2.VisualTree = sp;
                    extra++;
                    startDate = startDate.AddDays(1);

                }
            }

Hi Christopher,
instead of "buttonfactoy.AddHandler(Button.ClickEvent, ..." use Command property with ICommand class and CommandParameter bindet to current data item. In Execute method you get as state the item of clicked row.
