Bug report

The Core Grid throws an exception when setting its toolbar template through the ClientTemplateId option. The issue is a regression introduced in version 2025.2.520.

Reproduction of the problem

1. Configure the toolbar of the Grid like this:

.ToolBar(toolbar => {
     toolbar.ClientTemplateId("myTemplate");
})

Current behavior

An exception is thrown:

NullReferenceException: Object reference not set to an instance of an object

Expected/desired behavior

The configuration works without throwing exceptions.

Use the alternative way of setting the toolbar template, on the Grid's root level:

@(Html.Kendo().Grid <MyModel>()
      .Name("grid")
      .ToolBarClientTemplateId("myTemplate")

Expose the sorts TagHelper for the Grid's column filter datasource taghelper

Overview

Currently, the Grid's Column Filter Datasource Taghelper exposes the following inner child TagHelpers.

Unlike its HtmlHelper counterpart which happens to expose the .Sort() API configuration. For example:

.Columns(columns =>
{
    columns.Bound(p => p.ShipName).Filterable(ftb =>
    {
        ftb.Multi(true);
        ftb.Search(true);
        ftb.CheckAll(true);
        ftb.DataSource(dataSource => dataSource
            .Custom()
            ...
            .Sort(sort =>
            {
                sort.Add("ShipName").Ascending();
            })
        );
    });
})
