Hi,
I am finding hard to get sorting, filtering, and virtual scrolling all working togather in my code. Can someone assist me with a code. Just fyi, my grid has got lot of records say 50k so virtual scrolling fails with json error. As a workaround I disabled page view state but that is breaking sorting & filtering. Clear filter stops working and sorting gives nullreferenceexception at Infragistics.Web.UI.GridControls.Sorting.OnColumnSorted(ControlDataField column)
paging is not an option. thanks.
Hello rohitarora,
It has been a while since you have made your post, but I suppose the other community members can benefit from this answer as well.
You can change “maxJasonLenght” property in the “web.config” to much higher value in order to avoid Json exception like shown here - http://forums.asp.net/p/1090853/1634922.aspx
You can also refer to the following online example showing proper configuration of “VirtualScrolling” functionality - http://samples.infragistics.com/aspnet/Samples/WebDataGrid/Performance/Configuring-Virtual-Scrolling/Default.aspx?cn=data-grid&sid=f3cba022-35ab-4588-a9a8-0d5ffd768105
You can read our documentation for further explanation of “VirtualScrolling” here - http://help.infragistics.com/Help/NetAdvantage/ASPNET/2011.1/CLR4.0/html/WebDataGrid_About_Virtual_Scrolling.html
I hope that this information will help you to resolve the described issue.
