I am using asp.net chart control and i want to use chart click event to get the deptId value of bar click in bar chart .

  <Series>                       
                        <asp:Series Name="Tour" ChartType="Column" ChartArea="MainChartArea"  PostBackValue="#VALX">
                        </asp:Series>
                        <asp:Series Name="Inspection" ChartType="Column" ChartArea="MainChartArea" PostBackValue="#VALX">
                        </asp:Series>
                        <asp:Series Name="NightHalt" ChartType="Column" ChartArea="MainChartArea" PostBackValue="#VALX">
                        </asp:Series>
                    </Series>

  protected void AllDepartmentComparisonBarChart_Click(object sender, ImageMapEventArgs e)
