Hi - this one is a feature request, not a bug. :)

For the filter menu, when you enter a filter value, it would be nice if you could press enter to execute the filter instead of having to click "Filter."

When attempting to utilize the FilterMenuButtonsTemplate component, after selecting any of the defined action buttons (i.e., Clear, Filter, etc.), the selection will cause the page to refresh.

Steps:

1. Proceed to the Telerik Blazor documentation page for Filter Menu Buttons Template within the Grid component.
2. View the example for Using custom filter menu buttons.
3. Ensure that this is the first time loading the component as the error will only occur on the example page when first initialized.
4. Select the filter button within the “Price” column header.
5. Press the “Clear” button.

The Grid component creates an invalid property value in its style for the <table> tag like shown below (some of the contents omitted for brevity). Notice the "width: ;" which should have a value in it.

<table style="height: auto; width: ;"></table>

This can be observed for example by creating a page with the below code and the using the browsers developer tools to examine the elements. Both Grids will have their CSS width property be invalid.

<TelerikGrid Data="@data" AutoGenerateColumns="true">
</TelerikGrid>

<TelerikGrid Width="200px" Data="@data" AutoGenerateColumns="true">
</TelerikGrid>

@code {
    private List<Product> data = new () { 
        new Product() {
            Id = 2,
            Name = "Hello product"
        }    
    };

 public class Product {
        public int Id { get; set; }
        public string Name { get; set; } = string.Empty;
    }
}

If the Grid has no data, selecting null PageSize throws:

Error: System.ArgumentException: Page Size cannot be less than one (Parameter 'PageSize')

A possible workaround for the time being will be to use some conditional CSS to disable the PageSize dropdown while there is no data in the Grid: https://blazorrepl.telerik.com/QcOpkTlb38EDFboT34.

When the Grid PageSize exceeds the current data count and the InputType is Input, the Pager content cannot gain focus with the keyboard.

Here is a test page. A possible workaround is to switch the InputType at runtime. Then the user will be able to focus inside the Pager.

In some scenarios you may need a bit of extra code to get the current Grid item count.

<TelerikGrid Data="@GridData"
             Pageable="true"
             @bind-PageSize="@GridPageSize"
             Navigable="true">
    <GridSettings>
        <GridPagerSettings InputType="@GridPagerInputType"
                           PageSizes="@( new List<int?> { 2, 5 } )" />
    </GridSettings>

    <GridColumns>
        <GridColumn Field="@nameof(SampleModel.Name)" />
    </GridColumns>
</TelerikGrid>

@code {
    private List<SampleModel> GridData { get; set; } = new();

    private int GridPageSize { get; set; } = 5;

    //private PagerInputType GridPagerInputType { get; set; } = PagerInputType.Input;
    private PagerInputType GridPagerInputType => GridPageSize >= GridData.Count ? PagerInputType.Buttons : PagerInputType.Input;

    protected override void OnInitialized()
    {
        for (int i = 1; i <= 3; i++)
        {
            GridData.Add(new SampleModel()
            {
                Id = i,
                Name = $"Name {i}"
            });
        }
    }

    public class SampleModel
    {
        public int Id { get; set; }
        public string Name { get; set; } = string.Empty;
    }
}

I have a grid that can have a large number of pages and is intended to be able to be viewed on a small width device.

The issue is that upon loading the grid and its data, the pager of the grid isn't changing how it's displayed even though it is supposed to be adaptive.

If the page is manually resized, only then does the pager correctly show as a dropdown.

I've reproduced this in a REPL, though it seems slightly inconsistent as opposed to my main project where it is able to be reproduced every time.

In the attached gif, notice that upon loading the page, the grid shows the pager as a list of numbers as it would if the page was a large width screen, but when resizing the page slightly, it is triggered to show the pages as a dropdown, which I believe is the intended behavior.

Is this issue known and is there a way to trigger the grid to redraw its pager after the data is loaded, or some other form of workaround for this without implementing a custom pager template?

REPL

The feature request is to be able to customize the GridCsvExportOptions and GridExcelExportOptions from the API methods -

• ExportToExcelAsync
• ExportToCsvAsync
• SaveAsExcelFileAsync
• SaveAsCsvFileAsync

It will be useful to be able to customize the columns and data to be exported.

Telerik edit:

A possible workaround is to click the built-in Grid export buttons with JavaScript. With this approach, you will be able to use the built-in export options and events. Here is a REPL example.

Hello,

The Grid header and data cells become misaligned if the user changes the page zoom level. The right padding of the Grid header area resizes, according to the zoom level, but the scrollbar width remains the same. This triggers the misalignment.

The problem disappears after browser refresh at the current zoom level.

Please consider extending the GridColumn component to include fine-grained header presentation properties, such as:

• HeaderAlignment (e.g., Left, Center, Right)
• WrapHeaderText (bool)
• HeaderTooltip or HeaderAdornmentTemplate
  

These enhancements would dramatically improve clarity and usability in complex data grids.

Why This Is Important

In enterprise-grade applications — like ERP dashboards, financial reporting, or cutover schedules — grids are dense and loaded with meaning. Users rely heavily on headers to interpret the data beneath, especially when:

• Column headers are long or require abbreviations.
• Users need contextual guidance without clutter.
• Alignment improves visual scanning and aesthetics.

Would like a parameter in the grid definition that would display a Clear/Refresh button to return the grid to all originally selected records.  This feature would work similar to the Excel clear filter function.  

===

TELERIK EDIT: To reset the Grid filters, you can clear the FilterDescriptors collection and the SearchFilter property in the Grid state. Here is an example:

https://blazorrepl.telerik.com/cfEoatOr000uBdgW48

    private TelerikGrid<Product>? GridRef { get; set; }

    private async Task ClearGridFilters()
    {
        var gridState = GridRef!.GetState();

        gridState.FilterDescriptors = new List<IFilterDescriptor>();
        gridState.SearchFilter = default;

        await GridRef.SetStateAsync(gridState);
    }

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.

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.

I need to know which cell the user right clicked on so I can adjust my context menu. I need the cell value, the row model and the field of the column.

The following KB article shows a solution you can use immediately: https://docs.telerik.com/blazor-ui/knowledge-base/grid-which-cell-context-menu.

If after adding a new item to a grid with inline edit the save button is double-clicked (e.g. by accident) two new items are added instead of one. Right now, the only way to prevent this seems to be to check if an item is already contained in GridData at the top of the OnCreate-Handler and cancel if necessary.  If a unique ID is not available yet (because it is created by the database when saving at the end of the handler) this means every Property has to be compared to check for equality.  This is very annoying.

Please add a parameter "DisableWhileBeingHandled" to TelerikButtons and make this the default for the CommandButtons in a Grid. The Buttons should only accept clicks if the previous handling is finished.

Kind regards,

René

I have a master-detail draggable Grid scenario in which both Grids have RowDraggable="true". When the user starts dragging a row from the DetailTemplate Grid, a JavaScript error occurs:

TypeError: Argument 1 ('node') to Node.replaceChild must be an instance of Node

After filtering a nullable DateTime column, the SelectAll checkbox in the GridCheckboxColumn becomes selected, and its functionality stops working correctly.

When the Grid is databound via OnRead event, the initially displayed aggregates are wrong and take into account the first page only.

A possible workaround is to bind the Grid in OnAfterRenderAsync -

@using Telerik.DataSource
@using Telerik.DataSource.Extensions

<TelerikGrid @ref="@GridRef"
             OnRead="@OnGridRead"
             TItem="@Product"
             Pageable="true">
    <GridAggregates>
        <GridAggregate Field="@nameof(Product.Name)" Aggregate="@GridAggregateType.Count" FieldType="@(typeof(System.String))" />
    </GridAggregates>
    <GridColumns>
        <GridColumn Field="@nameof(Product.Name)" Title="Product Name">
            <FooterTemplate>
                @context.Count
            </FooterTemplate>
        </GridColumn>
        <GridColumn Field="@nameof(Product.Price)" />
        <GridColumn Field="@nameof(Product.ReleaseDate)" Title="Release Date" />
        <GridColumn Field="@nameof(Product.Active)" />
    </GridColumns>
</TelerikGrid>

@code {
    TelerikGrid<Product> GridRef { get; set; }
    List<Product> GridData { get; set; }

    bool ShouldBindGrid { get; set; }

    async Task OnGridRead(GridReadEventArgs args)
    {
        if (!ShouldBindGrid)
        {
            return;
        }

        await Task.Delay(200); // simulate network delay

        DataSourceResult result = GridData.ToDataSourceResult(args.Request);

        args.Data = result.Data;
        args.Total = result.Total;
        args.AggregateResults = result.AggregateResults;
    }

    protected override async Task OnAfterRenderAsync(bool firstRender)
    {
        if (firstRender)
        {
            // workaround for initial Grid aggregates
            ShouldBindGrid = true;
            GridRef.Rebind();
            StateHasChanged();
        }
    }

    protected override void OnInitialized()
    {
        GridData = new List<Product>();
        var rnd = new Random();

        for (int i = 1; i <= 50; i++)
        {
            GridData.Add(new Product()
            {
                Id = i,
                Name = "Product " + i.ToString(),
                Price = (decimal)rnd.Next(1, 100),
                ReleaseDate = DateTime.Now.AddDays(-rnd.Next(60, 1000)),
                Active = i % 3 == 0
            });
        }
    }

    public class Product
    {
        public int Id { get; set; }
        public string Name { get; set; }
        public decimal Price { get; set; }
        public DateTime ReleaseDate { get; set; }
        public bool Active { get; set; }
    }
}
