      CType(dataGrid1.TableStyles(1).GridColumnStyles(0), _
      MyGridColumn)
      Console.WriteLine(myGridColumn.GetMinHeight())
   End Sub 

End Class 

Public Class MyGridColumn
Inherits DataGridBoolColumn
   Public Function GetMinHeight() As Integer
      return me.GetMinimumHeight()
   End Function
End Class

public class Form1: Form
{
 protected DataGrid dataGrid1;

private void GetHeight(){
    MyGridColumn myGridColumn = (MyGridColumn)dataGrid1.TableStyles[1].GridColumnStyles[0];
    Console.WriteLine(myGridColumn.GetMinHeight());
 }
}

public class MyGridColumn:DataGridBoolColumn{
   public int GetMinHeight(){
   return this.GetMinimumHeight();
   }
}

public ref class MyGridColumn: public DataGridBoolColumn
{
public:
   int GetMinHeight()
   {
      return this->GetMinimumHeight();
   }

};

public ref class Form1: public Form
{
protected:
   DataGrid^ dataGrid1;

private:
   void GetHeight()
   {
      MyGridColumn^ myGridColumn = dynamic_cast<MyGridColumn^>(dataGrid1->TableStyles[ 1 ]->GridColumnStyles[ 0 ]);
      Console::WriteLine( myGridColumn->GetMinHeight() );
   }

};

public class Form1 extends Form
{
    protected DataGrid dataGrid1;
    private void GetHeight()
    {
        MyGridColumn myGridColumn = 
            (MyGridColumn)(dataGrid1.get_TableStyles().
            get_Item(1).get_GridColumnStyles().get_Item(0));
        Console.WriteLine(myGridColumn.GetMinHeight());
    } //GetHeight
}//Form1

public class MyGridColumn extends DataGridBoolColumn
{
    public int GetMinHeight()
    {
        return this.GetMinimumHeight();
    } //GetMinHeight
} //MyGridColumn
