Hello,
You cannot bind the chart to multiple datatables, so the additional columns should exist in the main one that you set as a datasource for the chart. For you convenience I am attaching a simple example of this here.

I SOLVE IT!!!!
ColumnSeries series = new ColumnSeries();series.DataFieldY = "data1"; //this is how I conect the Binding with the series (programmaticaly define)
RadHtmlChart1.PlotArea.Series.Add(series);RadHtmlChart1.PlotArea.Series[0].TooltipsAppearance.ClientTemplate = "..."
