When I lock a column that has a footer, the footer should be locked too.

Column virtualization is enabled.

I'm getting error for dynamic Grid InCell editing. Error is displayed on editing before calling UpdateHandler. It is observed for adding new row or editing any row. 

Error: System.ArgumentException: Instance property 'x' is not defined for type 'System.Dynamic.ExpandoObject' (Parameter 'propertyName')

I was not getting this error In previous version 2.21.0 on edit of a dynamic field. Getting this error after updating to new 2.23.0 version without any code change.

In hierarchical Grid with InCell edit the DateTime cells of the child Grid cannot be edited through the calendar popup. Trying to open the DatePicker or DateTimePicker popup of the child Grid automatically closes the edited cell.

When filtering using a GridSearchBox - to filter across all columns, we have an issue where if you change a GridColumns Visible attribute to false that row will still be visible in the grid results even though it no longer matches the filter.

Take this snippet for example: Telerik REPL for Blazor - The best place to play, experiment, share & learn using Blazor.

1. Use Search box and search for a Name. e.g "Chang"

2. Click "Toggle Name Visibility" button

Expected: Since Name column is now hidden, the column should no longer be used in filter and the row should no longer be displayed. In reference to the GridSearchBox: https://docs.telerik.com/blazor-ui/components/grid/filter/searchbox#filter-from-code where it's mentioned that the search box will filter only on columns that are visible. It doesnt seem to refresh the filter.

Actual: Row still displayed even though it no longer matches filter

Just wanting to raise this as an issue and also hoping you may know a potential work-around for this?

A potential work-around I have tried is re-applying the existing filter in the search box by following documentation here in the "Filter From Code" section: https://docs.telerik.com/blazor-ui/components/grid/filter/searchbox#filter-from-code

While I am able to apply a filter from code I cannot seem to retrieve the value that is currently in the search box as I want to reuse it. How can I achieve this with a GridSearchBox? There doesnt seem to be a property available on the GridSearchBox component for binding it's value. Would I need to create a custom filter input to achieve this?

Navigable="true" + OnRead data binding allow the user to go beyond the last Grid page. The component shows no rows, and even though the user can return to previous pages, it's cumbersome.

The workaround is to manage the Page value manually in the PageChanged handler.

@using Telerik.DataSource.Extensions

@*  workaround:  *@

@*Page="@GridPage"
PageChanged="@OnGridPageChanged"*@

<TelerikGrid OnRead="@OnGridRead"
             Navigable="true"
             TItem="@Product"
             Pageable="true">
    <GridColumns>
        <GridColumn Field="@nameof(Product.Name)" Title="Product Name" />
    </GridColumns>
</TelerikGrid>

@code {
    List<Product> GridData { get; set; }
    int GridPage { get; set; } = 1;
    int GridTotal { get; set; }

    // workaround
    void OnGridPageChanged(int newPage)
    {
        if (newPage > 0 && newPage <= Math.Ceiling((double)GridTotal / (double)10))
        {
            GridPage = newPage;
        }
    }

    void OnGridRead(GridReadEventArgs args)
    {
        var result = GridData.ToDataSourceResult(args.Request);

        args.Data = result.Data;
        args.Total = result.Total;

        // workaround
        //GridTotal = result.Total;
    }

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

        for (int i = 1; i <= 12; i++)
        {
            GridData.Add(new Product()
            {
                Id = i,
                Name = "Product " + i.ToString()
            });
        }
    }

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

When Grid is nested in a Window, pressing Escape key will bubble to the Window causing it to close during edit operation of the Grid.

1. Go to https://blazorrepl.telerik.com/mQaUcSlP59yrfqmM16 
2. Trigger Grid's keyboard navigation.
3. Press Escape(whether it is to close an Editor, or not).
4. Observe Window will close.

In the following reproducible, try filtering the third column (SomeNavigationProperty.Field1). It does not work.

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?

The problem is when filtering programmatically, the X that is normally used to clear the search box disappears.
I am following the Telerik guide here. https://docs.telerik.com/blazor-ui/components/grid/filter/searchbox

The problem is actually demonstrated in the example from that page.

Thanks.

Simplest repro code is below - expand a few rows and select items in them, or in the parent grid. I would expect that selection in each grid is independent, but the child grid seems to control the parent selection too, even though it is disabled.

<TelerikGrid Data="salesTeamMembers" PageSize="4" Pageable="true" @bind-SelectedItems="@SelectedItemsMainGrid" SelectionMode="@GridSelectionMode.Single">
    <DetailTemplate>
        @{
            var employee = context as MainModel;
            <TelerikGrid Data="employee.Orders" Pageable="true" PageSize="7" SelectionMode="@GridSelectionMode.None">
                <GridColumns>
                    <GridColumn Field="OrderId"></GridColumn>
                    <GridColumn Field="DealSize"></GridColumn>
                </GridColumns>
            </TelerikGrid>
        }
    </DetailTemplate>
    <GridColumns>
        <GridColumn Field="Id"></GridColumn>
        <GridColumn Field="Name"></GridColumn>
    </GridColumns>
</TelerikGrid>

@foreach (var item in SelectedItemsMainGrid)
{
    <div>@item.Name</div>
}

@code {
    List<MainModel> salesTeamMembers { get; set; }
    public IEnumerable<MainModel> SelectedItemsMainGrid { get; set; } = Enumerable.Empty<MainModel>();

    protected override void OnInitialized()
    {
        salesTeamMembers = GenerateData();
    }

    private List<MainModel> GenerateData()
    {
        List<MainModel> data = new List<MainModel>();
        for (int i = 1; i < 16; i++)
        {
            MainModel mdl = new MainModel { Id = i, Name = $"Name {i}" };
            mdl.Orders = Enumerable.Range(1, 15).Select(x => new DetailsModel { OrderId = x, DealSize = x ^ i }).ToList();
            data.Add(mdl);
        }
        return data;
    }

    public class MainModel
    {
        public int Id { get; set; }
        public string Name { get; set; }
        public List<DetailsModel> Orders { get; set; }
    }

    public class DetailsModel
    {
        public int OrderId { get; set; }
        public double DealSize { get; set; }
    }
}
