Thanks for contacting Syncfusion support.
We have analyzed your query. We could see that you would like to have “GET” request method for “UrlAdaptor”, we would like to inform you that using the “GET” will be very difficult to form a request url with all the paging and filtering query strings. As a filter like excel filter will generate complex query object(which includes predicates, queries), so if “GET” is used for “UrlAdaptor”, then large url will be generated for the request and it is very difficult to handle these. As we could see that you try to bind paging and filtering query with DataManagerRequest, using a “UrlAdaptor” with “POST” is the proper way.
So we suggest you to use the “UrlAdaptor” with “POST” request to achieve your requirement.
Please get back to us if you need further assistance.
