Is there anyone who has a working example with autocalc=sum in ChartDataCollection.
If you for example have 1 category it,s OK.
If you have more than 1 category, the errormessage is Specified cast is not valid.
Best regards Marianne
Please kindly check Chart_DataDrilling.aspx sample of WebGrid in your development PC. This is a working sample which implements autocalc=sum in ChartDataCollection.
protected void WebGrid2_ChartImageProcessing(object sender, WebGridChartEventArgs e) { if (Request["FilterExpression"] != null) { ... ChartPivotDataConfig data = new ChartPivotDataConfig(); data.DataMember = "ProductSales"; data.AutoCalc = AutoCalc.Sum; ... } }
Please let us know whether this helps or not.
