Chart does not display data when datasource is reset

[Jeffrey Monroe]

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,

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,
