How to obtain selected items in Grid?

[Steven]

Hello,

 

I saw the demo here: http://demos.telerik.com/aspnet-core/grid/checkbox-selection

I'm trying to do the same, but I can't get it to work.
this is my code: 

 

       @(Html.Kendo().Grid<CalculationResultModel>()
.Name("Grid")
.Columns(columns =>
{
    columns.Select().Width(50);
   ...
})
.Events(ev => ev.Change("onChange"))
   .DataSource(dataSource => dataSource
     .Ajax()
     .ServerOperation(true)
     .Model(model => model.Id(m => m.CalculationRequestIdentification))
     .Read(read => read.Action("x", "x").Type(HttpVerbs.Get))

     )
        )

when I call the selectedKeyName() function in the javascript, I get an empty array.

Any Idea why that can be? The Id is a Guid btw.

 

Thanks!

Wow... sorry , missed this line of code: .PersistSelection()

It works now.
