To get event to fire, it was necessary to add the eventhandler to each
imported series, but by doing so the chart on page which was zoomed is lost;
other charts on page or OK and formatting correctly.

By doing another post-back the zoomed chart now appears correctly.

To reproduce add two charts to page, set ZoomTool & SeriesHotspot Tools.

Code added after import.
theChart[x].Chart.Import.Template.Load(tmpChart);

int numSeries = theChart[x].Chart.Series.Count; //Set eventhandlers for
imported charts

for (int y = numSeries - 1; y >= 0; y--)

{

Steema.TeeChart.Styles.Series s = theChart[x].Chart.Series[y];

s.GetSeriesMark += new
Steema.TeeChart.Styles.Series.GetSeriesMarkEventHandler(fl_GetSeriesMark);

s.AfterDrawValues += new
Steema.TeeChart.PaintChartEventHandler(fl_AfterDrawValues);

}

Zoom in one chart, the other chart appears the zoomed chart does not. Do
another post-back zoomed appears correctly.
