This RadGrid is very new to me, having just begun my evaluation of the product yesterday. I may be way off in everything you see below... :-)
I have a RadGrid with a NestedViewTemplate. Inside of that, I have a RadTabStrip that deep inside it has three RadPageViews. No problem there. One of them looks like this:
Using a different charting component is not an option at the moment. If I use the charting-component in a "bare-bones" asp.net page, i would then generate and display the graph using this code:
But.... when using Rad controls, how do I get a reference to the "myChartControl" control, and how do I pass the selected value from my RadGrid to the code, so I can use the SelectedValue as a parameter for my chartHelper.GetChartWeb method?
And how do I "delay" invokation of the GetChartWeb method, so the chart is generated on demand when a user clicks the "chart" tab of my tabstrip?
So far very impressed by what's possible with the RadGrid, but growing DEpressed with still being exactly where I was 24hrs ago. Stuck. :-(
Hoping all of this makes sense to someone :-))

Hi Jeppe,
You can access the charting component inside the ItemDataBound server handler of the grid (using the FindControl(id) method of the framework) in order to reference it and pass the selected value from the grid to the GetChartWeb method as a parameter). For this purpose you can use either the SelectedValue property of the grid or the GetDataKeyValue(fieldName) method for the respective GridDataItem instance.
To load the chart on demand when the grid items are expanded, consider the approach with the hidden panel presented on this demo:
