Paging and Sorting
Hi,
I'm creating a GridPanel where I need to implent the Paging Sort. I followed that example (https://examples1.ext.net/#/GridPane...rting/Handler/) and I implemented with DataBase (625 rows), but isn't work. During execute "context.Response.Write(JSON.Serialize(pageCliente ));" occurs a error.
Image with error message attached!
Grid.Aspx
Thankful for attention!
