Answer 1

DataGridTemplateColumn dataGridComboBoxTemplateColumnObj = new DataGridTemplateColumn();
dataGridComboBoxTemplateColumnObj.Header = column.Header;
FrameworkElementFactory comboBoxFactory = new FrameworkElementFactory(typeof(ComboBox));
Binding bindingItemSourceObj = new Binding(column.ItemsSourcePropertyName);
comboBoxFactory.SetValue(ComboBox.HorizontalAlignmentProperty, HorizontalAlignment.Stretch);
comboBoxFactory.SetValue(ComboBox.ItemsSourceProperty, bindingItemSourceObj);
comboBoxFactory.SetValue(ComboBox.SelectedValuePathProperty, column.ValuePropertyName);

Binding selectedValueBindingObj = new Binding(column.PropertyName);
selectedValueBindingObj.Mode = BindingMode.TwoWay;
selectedValueBindingObj.UpdateSourceTrigger = UpdateSourceTrigger.PropertyChanged;
comboBoxFactory.SetValue(ComboBox.SelectedValueProperty, selectedValueBindingObj);
dataGridComboBoxTemplateColumnObj.CellTemplate = new DataTemplate();
dataGridComboBoxTemplateColumnObj.CellTemplate.VisualTree = comboBoxFactory;
dataGridColumnObj = dataGridComboBoxTemplateColumnObj
