        //check the selected index
        if (e.AreaIndex == 0)
        {
            //write the clicked index in the session object
            Page.Session["index"] = "0";
         }
         //if second bar is clicked
        else if (e.AreaIndex == 1)
        {
            //write the clicked index in the session object
            Page.Session["index"] = "1";
         }
      .......

        //redirect
        Response.Redirect("PieChart.aspx");
    }

Visual Basic

Protected Sub BarChart1_Click(ByVal sender As Object, ByVal e As MindFusion.Charting.WebForms.Chart.AreaEventArgs)
        'check the selected index
        If (e.AreaIndex = 0) Then
            'write the clicked index in the session object
            Page.Session("index") = "0"
        End If
        'if second bar is clicked
        If (e.AreaIndex = 1) Then
            'write the clicked index in the session object
            Page.Session("index") = "1"
        End If
        'redirect
        Response.Redirect("PieChart.aspx")
    End Sub
