Creating reports and dashboards | Stimulsoft community forum

Hi,

I have a very simple chart. It has a column where some values can be NULL and I want to hide these data points. But, as soon as I use my custom CacheHelper class, the setting to ShowNulls within chart series is ignored and they are all printed regardless.

StiWebViewer.CacheHelper = new StimulsoftViewerCacheHelper();

CacheViewer line commented (display is correct): CacheViewer line uncommented (display is wrong): I have also attached a C# project if you want to replicate. You will have to restore packages from NuGet and build it again.

Cheers,
Vineet

I can replicate this behaviour by setting CacheMode = "StringCache" on the WebViewer tag:

<cc1:StiWebViewer ID="StiWebViewer1" runat="server" CssClass="vwr"
OnGetReportData="StiWebViewer1_OnGetReportData"
OnGetReport="StiWebViewer1_OnGetReport"
OnViewerEvent="StiWebViewer1_OnViewerEvent"
OnExportReport="StiWebViewer1_OnExportReport"
CacheTimeout="3600"
RequestTimeout="1200"
AllowAutoUpdateCache="True"
ShowServerErrorPage="False"
ParametersPanelPosition="Top" ParametersPanelColumnsCount="2"
ShowFullScreenButton="False"
ShowFindButton="False"
ShowPrintButton="False"
ShowSaveButton="False"
ToolbarDisplayMode="Simple"
ShowAboutButton="False"
UseCompression="False"
CacheMode="StringCache"></cc1:StiWebViewer>

Hello

Thank you for the information.
Please let us know if you need any additional help.

Thank you.

Yes I do, the bug is happening as per my findings. If I don't use a custom cacheHelper and just set the CacheMode of the viewer to StringCache, "ShowNulls" is still being ignored.

Hello,

That issue was fixed, will be available in the next release in September.

Thank you.

Hi Lech, When are you releasing the next version?

Hello,

We hope to release it in the end of September, hopefully next week.

Thank you.
