The drill down facility is not working for line chart series. How to
achieve drill down functionality if I want the user to be redirected to
different pages when they click on different line chart series?
I have tried using RadChart1_Click event but its not working.

Hello Matthew,
The"other thread" turned out to be a private support ticket. Onto your question -- you can access the actual ChartSeriesItem which has been clicked is available from the event arguments send to the event handler:
args.SeriesItem gets the ChartSeriesItem being clicked. When the chart is populated, you can set ChartSeriesItems' Name property in order to distinguish them in the Click event handler.

Thanks.
Can you confirm this works with a line chart?
I changed the chart on your postback sample from a bar to a line and the postback stopped working.
I assumed from that and other stuff on the forum that 'clicking on a line series postback event' is not supported.
Or am I mistaken and there's ome other setting I need to change too?
cheers

Hi Matt,
Sorry for the misleading answer -- the click event for a line chart will work only for the pointmarks, which would be the actual clickable areas. If you do not need pointmarks, you can set their color to Transparent, so they will be invisible, but clickable. You can also define their size.
Hope this helps.
All the best,

... <telerik:ChartSeries Type="Line" DataXColumn="Year" DataYColumn="Rev" Name="Years"> |

<PointMark Visible="True" Dimensions-AutoSize="false" Dimensions-Height="10" Dimensions-Width="10"> |
<FillStyle MainColor="Transparent"></FillStyle> |

Hope this helps.

Thanks, that sounds great.
I suppose, though, there will be a performance penalty if there are thousands of pointmarks

Hello Matthew,
Unfortunately, that is correct. You can pre-filter the data before it is sent to chart or combine several data points into one ChartSeriesItem if feasible.
