Grid.Selectable() cause Uncaught TypeError: Cannot read property 'get' of null

[Chris]

HI

I met a error about Grid : 

  Uncaught TypeError: Cannot read property 'get' of null

I have test my code and found that the Selectable(true) will cause this error : 

View

      @(Html.Kendo().Grid(Model.ListProperty1)
        .Name("ListProperty1Grid")

        .Selectable(selectable =>
        {
          selectable.Enabled(true);
        })


Javascript

        var grid;
        var dataSource;
        //
        dataSource = new kendo.data.DataSource(
        {
            data: ...
        });
        //
        grid = $("#ListProperty1Grid").data("kendoGrid");
        grid.setDataSource(dataSource);

Grid's BUG ?

Hello Chris,

Based on the provided information, I tested the scenario and I was not able to replicate the problem.

Having said that, in order to continue my investigation, could you please share an isolated example that clearly demonstrates the problem? This example will help us fully understand the case and we might be able to eventually provide a workaround.

I look forward to hearing from you.

I also continuously get this same error and cannot track down the cause.

Has the cause of this been identified yet?

Hi David,

For the time being, we were not able to identify the cause of the described issue.

Having said that, it will help me a lot to investigate the issue further if you prepare and share a sample isolated project that clearly replicates and demonstrates the issue. This project will help me in fully understanding the case and eventually I might be able to find a workaround.
