I am quite new to WPF (from Winforms). I am using .Net 4.5 and the default DataGrid that comes along with the framework in WPF. The columns are created dynamically because I do not know at compile time. Now, based on data some columns will be read-only and some will be of ComboBox type.

How can I apply this logic dynamically while creating the columns dynamically as shown below. here is the code which I wrote so far. Whenever the data changes, the columns are generated dynamically based on the data.
Also, how do I generate "different types" of column dynamically (ComboBox, TextBox, etc…) based on data. The MVVM-ish way in WPF is kind of restricting me because I do not have much knowledge about templating. I am sure it should be easy once I get through.

NB: Currently all this is working fine. I have a read-only databound grid. But, there is no support for selective editable columns and selective ComboBox columns.

public class DatagridExtension {
    
    public static readonly DependencyProperty RefDataSourceProperty =
        DependencyProperty.RegisterAttached(
            "RefDataSource",
            typeof(RefDataRecord),
            typeof(DatagridExtension),
            new PropertyMetadata( default(RefDataRecord), OnRefDataSourceChanged)
        );


    private static void OnRefDataSourceChanged(DependencyObject d, DependencyPropertyChangedEventArgs e)
    {
        var grid = d as DataGrid;
        var dataSource = e.NewValue as RefDataRecord;

        grid.ItemsSource = dataSource;
        grid.Columns.Clear();
        int count = 0;
        foreach (var col in dataSource.Columns)
        {
            grid.Columns.Add(
                new DataGridTextColumn
                    {
                        Header = col.Name,
                        Binding = new Binding(string.Format("[{0}]", count))
                    }
                );
            count++;
        }
    }

    public static RefDataRecord GetRefDataSource(DependencyObject dependencyObject)
    {
        return (RefDataRecord) dependencyObject.GetValue(RefDataSourceProperty);
    }

    public static void SetRefDataSource(DependencyObject dependencyObject, RefDataRecord value)
    {
        dependencyObject.SetValue(RefDataSourceProperty, value);
    }
}
