Hi there,
currently the grid component does not provide a feature to set a specific position in virtual scrolling mode.
My team has currently implemented a workaround via javascript interop call to set a specific position. The workaround basically calculates the "scroll value" (we reverse engineered this value by looking at the Telerik js code) and passes it to the jQuery scrollTop() function. This results in an update of the scrollbar which in return triggers the OnReadItems event where we fetch the items based on the given skip and take values.
This workaround does not seem to work in all cases and is somewhat unreliable hence i'm requesting an official feature to set a specific position without the javascript hack.
What do you say?

Our application has, on many pages, complex business logic to enable or disable specific cells based upon the viewing mode, the user's capabilities, the type of data in the row, etc. If a cell is to be disabled, we also want to change the background color.. This is easily accomplished with the OnCellRender property.
However, we cannot enable/disable specific cells within a column without creating a column template with conditional logic. And so, in all our grids, EVERY column has to have a template, just for that trivial function. And now we have business logic smeared across both the razor page and the code page.
A template should be required only if you are doing something unusual or exceptional. Setting a cell to be enabled or disabled is completely routine, and one should not have to create a template just for that.
If you would add a property such as OnCellEnable, to override the column Enabled property on a per-cell basis, it would be extremely useful and would eliminate the need for literally hundreds of templates.

Please add a ToolbarTitle property to grid components, with an optional ToolbarTitleTooltip or ToolbarTitleAdornmentTemplate. This would allow developers to display a title with optional help text directly in the toolbar — giving users immediate context on the data being displayed.
Why This Is Valuable
In enterprise apps — particularly in areas like dashboards, scheduling, and ERP grids — users are often viewing:
- Similar grids across multiple tabs or modules
- Role-specific data views (e.g., “My Open Tasks”, “Org View Only”)
- Filtered subsets or critical cutover lists
Providing a toolbar-level title with a subtle help icon improves discoverability and reduces confusion — especially when filters or dynamic data shaping is in play.
Please add a built-in way to define a list of predefined filters (filter presets) within the ToolbarTemplate of a grid. This would allow users to quickly select a filter configuration, which is then automatically applied to the grid’s DataSourceRequest.
Why This Is InvaluablE
In enterprise apps with dense, multi-column grids, users often need to:
- Filter to common scenarios (e.g., “My Tasks”, “Due This Week”, “Unassigned Only”).
- Avoid re-entering the same filters repeatedly.
- See role- or context-based presets applied consistently
Currently, implementing this requires custom filter logic, state management, and manual data reloading — even though the concept is straightforward from a user’s perspective.
Please add support for a right-side filter panel (sidebar) that dynamically renders filter controls based on the grid’s visible columns and their editor templates. The panel would allow users to apply multiple filters at once, similar to SharePoint’s column filter experience — in a tall, narrow layout with an “Apply Filters” button.
Why This Matters
While column-level filters are useful, in real-world business apps:
- Users often want to set multiple filters at once without interacting with tiny filter icons.
- They need to see all available filters in one place — especially in cutover task lists, audit views, or reporting grids.
- This UI pattern is familiar from tools like SharePoint, Power BI, and Microsoft Lists.
Currently I need to define a custom JsonConverter to serialize the state of the grid. I would prefer not to have to do this, however I understand that may just be the way things are for now. Creating this ticket / issue to track if this is ever changed to not being needed.
For now I'll be setting up two serializers, one just for the grids that uses Newtonsoft, and the one I would prefer to use that uses System.Text.Json, https://github.com/Blazored/LocalStorage.
From https://docs.telerik.com/blazor-ui/components/grid/state
// to store the serialized grid state, we need to have a custom serialized // based on Newtonsoft.Json serialization. In the future this may not be required public class FilterDescriptorJsonConverter : JsonConverter {

Using CheckBoxList filtering changes the filter menu for all columns. I would like to specify CheckBoxList only for certain columns, but that doesn't currently appear to be an easy option.
1) Leave as FilterMenuType "Menu" but implement a custom filter template for the columns I want. That would be the most obvious, but CheckBoxList is not a usable control on its own?
2) Or do the inverse, use FilterMenuType "CheckBoxList" and implement a custom filter template for all the columns where I don't want to use that. Seems like a lot of extra work to manually recreate default filters.
3) I guess I roll my own clone of the CheckBoxList control and use that like #1 on individual columns?
Any chance the CheckBoxList control could be publicly exposed for direct use?
