Hi,
I have written an excel export functionality for WebChart. This functionality iterates through all series of my composite charts and writes the values of the series in a excel sheet.
After update from version 9.2 to version 10.2 of Infragistics the series collection is always empty. I enabled view state and tried a lot of other things but everything is empty.
How can I get my export working again?
Thanks
I found the problem my self: I hade a "if (IsPostback) return;" at the beginning of of PageLoad.
Sorry
This is a strange behavior and so far I haven't been able to reproduce it. Is is possible for you to include a sample project? If this is version specific somehow, please include the version and the build number of NetAdvantage you're using. First, I thought this could be caused by the postback, but that doesn't appear to be the case, so maybe it is a problem in the version you're using or something got messed up during the upgrade. You can try installing the latest service release, if you haven't done so already to see if it was indeed the version. You can try creating a new simple project with a chart and see if maybe it was due to the upgrade process.
sorry for late reply. Yes I can see my series. The display of the data works fine. I have a composite chart and I add my series from code.
Both, chart.Series and chart.CompositeChart.Series is empty.
The only thing is, when I press my button to export data I try to iterate through all series. But series collection is empty. In previos version it was not.
Hello,
To investigate this issue further, can you send me the approach you are taking to add series to the chart so I can may investigate this further?
Thanks,
Bhadresh
I'm having trouble reproducing this problem. How are you adding the series to the chart? Are you doing this through the markup or code? Is chart.Series and chart.CompositeChart.Series both empty? Are you able to see any output on the chart?
If possible, can you include a sample to help us reproduce this issue?
