Disable Text Wrapping on a Dynamically Filled DataGrid WPF

As the title mentions I am creating a DataGrid as follows: 

dataGrid = new DataGrid();
dataGrid.ItemsSource = dSet.Tables[i].DefaultView;

and adding it inside a WrapPanel. Everything is working but I need to disable the text wrapping on rows with multiple lines and limit the column width and having them displaying three dots.

I tried styling the DataGridCell but nothing is working for me.

Can anyone help with this?

Note: I cannot create predefined columns since this is a dynamic grid that I cannot determine before what columns it will populate.

You could handle the AutoGeneratingColumn event and use a converter that converts the long string to a shorter one:

dataGrid = new DataGrid();
dataGrid.ItemsSource = dSet.Tables[i].DefaultView;
LongTextConverter LongTextConverter = new LongTextConverter();
dataGrid.AutoGeneratingColumn += (ss, ee) => 
{
    DataGridTextColumn column = ee.Column as DataGridTextColumn;
    column.Binding = new Binding(ee.PropertyName) { Converter = LongTextConverter };
};

LongTextConverter.cs:

public class LongTextConverter : IValueConverter
{
    public object Convert(object value, Type targetType, object parameter, CultureInfo culture)
    {
        string s = value as string;
        if (!string.IsNullOrEmpty(s) && s.Length > 10)
            return $"{s.Substring(0, 7)}...";

        return value;
    }

    public object ConvertBack(object value, Type targetType, object parameter, CultureInfo culture)
    {
        throw new NotSupportedException();
    }
}
