Hi Evgeni,    

   

Sorry for the delay.    

   

We have analyzed the provided code snippet and found that you have tried to assign the PdfLightTableDataSourceType to DataSourceinstead of DataSourceType. So kindly use the below code snippet to overcome the reported issue,    

   

Codesnippet:    

//Declare a PdfLightTable   

PdfLightTable table = new PdfLightTable();   

   

//Set the Data source as direct   

table.DataSourceType = PdfLightTableDataSourceType.TableDirect;   

   

We have created the sample to illustrate this and please find the download link from below,    

Sample: https://www.syncfusion.com/downloads/support/forum/152406/ze/GettingStarted-744088158    

   

Please try the above sample and let us know the result.

Thanks for help, it works. It's just odd because in the previous version 17.1.0.43 everything was okay.
