Hi Evan,
Thanks for using Syncfusion products.
I am afraid that I am not able to reproduce the issue, you have mentioned. Please refer the following steps that I tried to reproduce it:
1. Created a simple sample with GGC in MasterPage.
2. Binded it with Database.
3. GGC includes PagerBar .
4. While running the sample the clicking on the next, previous options in PagerBar doesn’t throw any exceptions..
Please refer the sample from the below link which illustrates the above.
http://websamples.syncfusion.com/samples/Grid.Web/6.3.0.10/Grid_Web_Paging/main.htmPlease try the above, if still the issue exists, could you please send us a simple sample to reproduce the issue? so that we could sort out the cause of the issue and provide you a better solution.
Regards,
Raji
