How to assign checkbox on DataGrid row headers from code behind?

Question

In my WPF application I create Datagrid dynamically from code behind. However, I want to have a datagrid with check boxes on row header similar to this.

I know how to do it from XML, but not from cs code. Is there any idea how to handle this situation? ps. my code is very big I cannot put it here but if you need more info, please put comments below. Cheers

How about something like this:

var dg = new DataGrid();

var dataTemplate = new DataTemplate();

var gridFactory = new FrameworkElementFactory(typeof(Grid));
var checkboxFactory = new FrameworkElementFactory(typeof(CheckBox));
checkboxFactory.SetBinding(CheckBox.IsCheckedProperty, new Binding("IsSelected") { RelativeSource = new RelativeSource(RelativeSourceMode.FindAncestor,typeof(DataGridRow),1)});
gridFactory.AppendChild(checkboxFactory);

dataTemplate.VisualTree = gridFactory;
dg.RowHeaderTemplate = dataTemplate;

Hopefully this should be able to be put into your code without too much effort, probably just have to change the DataGrid name from "dg".

Thank you! It works for me. I do this with the XamlReader class because the FrameworkElementFactory class is now deprecated.
