How to pass GridView as a ConverterParameter

Question

I am trying to pass the ListView or the GridView as a ConverterParameter However, in the Converter routine the parameter is coming as a type string

Below is the part of the XAML List view and the Converter class.

Any help greatly appreciated. Thanks!!!

    <ListView Name="SeqDtStDataListView1" Grid.Row="1" 
        DataContext="{Binding Path=DisplayDT[0], Converter ={StaticResource      
                                                       CNVToColumn},ConverterParameter=?????}"
        VerticalContentAlignment="Stretch" VerticalAlignment="Stretch"
                                                       HorizontalAlignment="Stretch"
        SelectionChanged="SEQDatalistview_SelectionChanged"  Margin="5"> 


       <ListView.View >
             <GridView x:Name="SeqDtStDataGridView1"/>
       </ListView.View>
    </ListView>

Converter:

namespace MFTest.Converters
{
public class CNVToColumn : IValueConverter
{

    public object Convert(object value,
                          Type targetType, 
                          object parameter,
                          System.Globalization.CultureInfo culture)
    {
        DataTable dt = (DataTable)value;
        GridView GV = (GridView)parameter;                <========= fail here ===========
        if (dt != null && GV != null)
          foreach (var colum in dt.Columns)               // Binding the Columns
          {
                DataColumn dc = (DataColumn)colum;
                GridViewColumn column = new GridViewColumn();
                column.DisplayMemberBinding = new Binding(dc.ColumnName);
                column.Header = dc.ColumnName;
                GV.Columns.Add(column);
          } 
        return null;
    }

    public object ConvertBack(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
    {
        throw new NotImplementedException();
    }

}
}
