Multiple calls to Controller action method?

[Jonas]

Hi,

We are using the Grid widget for ASP.NET Core which uses AJAX calls to our ASP.NET Core MVC Controller action methods.

Why would the Read method result in multiple calls to the Controller action method?

 

                .DataSource(dataSource => dataSource
                    .Ajax()
                    .Events(e => e.RequestStart("onRequestStart"))
                    .Read(read => read.Action("ListCars", "CarController"))
                )

Hello Jonas,

Usually, this will cause only one call to the server, unless there is custom logic on some of the Grid and the dataSource events, which may cause the additional calls:

I noticed that the RequestStart event of the dataSource is also used, please check the logic executed on the event.

If the issue still occurs, please send a fully runnable example, and I will gladly assist.
