Kendo Hierarchical Grids reload data of first opened details grid

Question

I got 2 grids in hierarchy:

            .Name("Obj")
            .Columns(columns =>

                            read.Action("ResourcesChildren_Read", "ICSForms",
                                     new { resourceID = "#=ResourceID#" }))
                .Update(update => update.Action("Resources_Update", "ICSForms"))
                .Destroy(destroy => destroy.Action("Resources_Destroy", "ICSForms")).AutoSync(true)
            ).ToClientTemplate()
        )

    </script>

The problem is that if I open the details of one of the rows and I see everything that has that parent (so far so good) and I open another details grid it opens an empty one and the first one refreshes its data with the ids of the second opened element.

I researched this issue, but I couldn't find similar occurrences. Any help solving this would be much appreciated.

Answer 1

You need a unique name for every instance of a grid.

<script type="text/kendo" id="rTemplate">
    @(Html.Kendo().Grid<Model>()
        .Name("childObj_#=ResID#") //Assuming ResID is the parent model's ID (I think #=id# would work as well if you have set the Id in the model)
[...]

If you use $("#childObj") anywhere, you will have to refactor that somehow.
