  I have the following code that gets called on form load and when a button is clicked:
  
  

  rcSummary.Series.Clear()

  rcSummary.RemoveAllSeries()

  rcSummary.Clear()

  rcSummary.DataSource = PersistenceHelper.GetResponseContentDailySummary(_dbContext, rdtStartDate.Value.Date)

  
  The chart displays with the proper data when the form loads. If the button is clicked on the form, the chart displays "There is no or empty series".
  
  I have verified the correct data is returned by the GetResponseContentDailySummary function.
  
  Any help would be much appreciated,
  -jm

  Hello Jeffrey,
  
  Please, add a call to the DataBind method of RadChart after setting its DataSource property:
  

  rcSummary.DataSource = PersistenceHelper.GetResponseContentDailySummary(_dbContext, rdtStartDate.Value.Date)

  rcSummary.DataBind()

  
  
  Kind regards,
  Giuseppe
