Hi,

  I am unable to perform drillback functionality in ultrawinchart and I have tried the following things,

1)  this.ultraChart1.Drill.ShowButton=true  (At designtime and as well as in the runtime)

2)  private void button1_Click(object sender, EventArgs e)

    {

        ultraChart1.Drill.DrillBack();

     }

But still i am unable to perform drillback and is there any other related property that i have to enable.

Thanks!!!
