We are using Infragistics4.Web.v14.1 and implemented the WebHierarchicalDataGrid in our project.When we filter on large amount of data, "Async request failed" error occured.So we tried a free trail of infragistics new version 18.1.20181.23.Then also same issue occured and also filter is not working for data source having empty strings.What's the solution for this.
Looking forward for your reply.
in.zipHere we attaching the isolated sample.Please check this.
When I run your sample the grid filters the data without issue. What are the details of the error? Was there an exception on the server or did it simply timeout?
If it is timing out, maybe you can increase the timeout using the approach suggested in How to change the timeout of a WebDataGrid?
