StiWebDesigner - Object reference not set to an instance of an object

kamberkar · Post by **kamberkar** » Tue Oct 27, 2020 9:17 pm

Hello There,

I'm converting from older version of report designer to Stimulsoft.Reports.Web.2020.4.2\lib\net45\Stimulsoft.Report.WebDesign.dll. The main reason is to come out of flash version of Stimulsoft. I also added my license key in the startup. I'm getting following error. Really appreciate any help.

Exception information:
Exception type: NullReferenceException
Exception message: Object reference not set to an instance of an object.
at Stimulsoft.Report.Web.StiWebDesigner.RegisterClientScriptBlockIntoHeader(String key, String script) in D:\Stimulsoft\Stimulsoft.Reports\Stimulsoft.Report.WebDesign\Designer\StiWebDesigner.cs:line 94

My aspx code.
