Hello Ruben, The prescriptive approach to support server-side filtering and paging is to use the JFP and specify a count function. However, you can provide your own mapping plugin to implement your own logic for server-side filtering and paging. If you do not need to invoke a count function, then you can set transport.countFnName to undefined so that this logic is not called. If you have enabled server-side operations via Kendo UI Builder (by turning off Client-Side Operations), the code is expecting a function and will error out if the Count Function field is left blank. It will be interpreted as "" instead of undefined. Here are a couple of approaches. A possible workaround here would be to programmatically override the Data Source options and set countFnName to be undefined. Another alternative, would be to set the Count Function to a function that is local in the JSDO, add it dynamically to the JSDO so that when it is called, the call is done on the client, rather than calling a function on the server (avoiding using PUT). You would need to make sure that the function returns a Promise so it can work as a replacement of the invoke count operation. Please let me know if you need more details on either approach. Considering that you are using your own implementation for the calculation of the count, you may want to use the server.count property with a custom mapping plugin so that Kendo UI knows the value for the count. See the following link for info: - documentation.progress.com/.../index.html I hope this helps.
