I am trying to determine how best to store off a key that goes with each series item. I guess I'm looking for a way to tag each series item so that when a user select it, I can get this Id so I can pass to another page. I'd like to get this from RadGrid1_Click event. I am currently using the XValue2 property and that seems to work because I'm just showing Pie or Bar charts only, I doubt that is what I should be doing. We are not using databinding and I am building the series by hand.
Just a background on why I need this. We are displaying a bar chart that shows a list of Items and their value. When the user clicks one of the items, I need to go to our DB and retrieve more details. Everything in our DB is keyed by a unique Id.
I didn't see this covered in the documentation but I'm sure it's possible.
Thanks

Hi Randy,
There is no designated property for this purpose. You have already found the workaround -- use XValue2 or any other unused ChartSeriesItem property - YValue2, YValue3, YValue4, Name, Label. Note, that if you use the Label property the ID will appear as a label, so this would be suitable only if you do not plan to show item labels. In a similar way -- you can use the Name property only if it is OK to let the ID appear in the legend (usually in a pie chart with LegendDisplayMode = "ItemLabels") or if the legend is hidden.
Hope this helps.
