Telerik input components inside EditorTemplate render the whole grid on each keystroke

<AdminEdit>

As a workaround, you can use the standard Input components provided by the framework together with a CSS class that would visually make them like the Telerik Input Components. An example for the TextArea:

<InputTextArea class="k-textarea" @bind-Value="@myValue"></InputTextArea>

</AdminEdit>

A nice feature would be frozen Group Rows.

So if you grouped your data in the Grid and scroll. The Group should stick underneath the header.

As an example look here: https://www.ag-grid.com/angular-data-grid/grouping-sticky-groups/

How do I get the filter menu to allow input of Date *and* Time for a DateTime column?

In Grid with Filter Menu, I want to trigger the Filter button on Enter press while the focus is still on the filter input.

Currently, it is possible to fire filtering from keyboard only if you tab through the Filter Menu elements to focus the Filter button and then press Enter.

I have applications for which I would like to define the default join operator for Grid filters to be "OR" instead of the default "AND."

Please expose an option to customize the default logical operator in Filter Menu.

Grid column header and content alignment (horizontal +Vertical)

ADMIN EDIT

For the time being, this is possible through the CellRender event, see below in the thread for an example.

The Grid selection performance is worse in WASM when there is a command column. Here is a test page with a large page size, which makes this more evident.

<label><TelerikCheckBox @bind-Value="@ShowCommandColumn" /> Show Command Column</label>

<TelerikGrid Data="@DataList"
             SelectionMode="@GridSelectionMode.Single"
             Height="700px">
    <GridColumns>
        <GridColumn Field="@(nameof(DataModel.Pos))" Title="Pos" />
        @if (ShowCommandColumn)
        {
            <GridCommandColumn Width="300px">
                <GridCommandButton Command="Save" Icon="save">Reset Volume</GridCommandButton>
                <GridCommandButton Command="Delete" Icon="delete">Delete</GridCommandButton>
            </GridCommandColumn>
        }
    </GridColumns>
</TelerikGrid>

@code {

    bool ShowCommandColumn { get; set; } = true;

    List<DataModel> DataList { get; set; }

    protected override async Task OnInitializedAsync()
    {
        DataList = new List<DataModel>();
        for (int i = 1; i <= 500; i++)
        {
            DataList.Add(new DataModel
            {
                Pos = i
            });
        }
    }

    public class DataModel
    {
        public int Pos { get; set; }
    }
}

I have a Grid with numerous columns and I am using inline editing. When in edit mode, I'd like to add custom content to each cell - for example, a validation error message from server validation.

To achieve that, I have to use EditorTemplate. However, I want to keep the default editor because I'd like to avoid having to add the relevant control for every single cell each time I add a new Grid.

Consider the following example. It will trigger AmbiguousMatchException, because reflection discovers two SpecialProp properties.

<TelerikGrid TItem="@GridModel"
             Data="@GridData"
             AutoGenerateColumns="true">
</TelerikGrid>

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

    protected override void OnInitialized()
    {
        for (int i = 1; i <= 3; i++)
        {
            GridData.Add(new GridModel()
            {
                SpecialProp = i,
                Text = "Text " + (i * 111)
            });
        }
    }

    public record GridModel : Base1 { }

    public record Base1 : Base2
    {
        public new decimal? SpecialProp { get => base.SpecialProp / base.HelperProp.GetValueOrDefault(1); set => base.SpecialProp = value.HasValue ? (int)(value.GetValueOrDefault() * base.HelperProp.GetValueOrDefault(1)) : null; }
    }

    public record Base2
    {
        public int? SpecialProp { get; set; }
        public string Text { get; set; }
        public int? HelperProp = 10;
    }
}

Why not replace

private PropertyInfo FieldPropertyInfo => ContainerGenericArgument?.GetProperty(Field);

with something like

PropertyInfo FieldPropertyInfo = ContainerGenericArgument?.GetProperties().FirstOrDefault(p => p.Name == Field);

with the possibility to cache the result from GetProperties()?

The `Context` of `<GridColumn>` is of type `object`, requiring typecasting in order to use the value.

Instead, make `<GridColumn>` generic so that `Context` is strongly typed.  If you use `TItem` as the name for the generic then Blazor will infer it without the user having to specify it.

Key events will allow developers to enhance and customize the Grid keyboard navigation. For example -

Detect when the user presses the down-arrow key when on the last grid row. We want to force a "next page" when they do this, and a "previous page" if they are at the top of the grid and press the up-arrow key.

ADMIT EDIT

Everyone, please feel free to list other scenarios as well.

Description

The left offset style value is not correctly formatted. It is culture-specific, however, the CSS rules should be formatted with culture invariant decimal separator - dot. 

Reproduction (if bug)

1. Create a grid with locked columns. 

2. Set the culture to one that has a comma as the decimal separator.

3. Resize the frozen columns, the left value is formatted with a comma instead of a dot.

Expected (if bug)

The value should be formatted with a dot.

Trying the custom GridCommandButtons. When recieving the event, the CommandName of  the GridCommandEventArgs is always null. Shouldn't this be the name of the command I specified on the command?

 Explore you example at
https://docs.telerik.com/blazor-ui/components/grid/toolbar#custom-commands

 When private void MyCommandFromToolbar(GridCommandEventArgs args) is triggered, I expect the command name to be MyToolbarCommand

Description

OnRead event is triggered multiple times when the page is different from the first one and the page size is changed.

Reproduction (if bug)

1. Create a grid and set the pageable and page sizes options

2. Navigate to a page different from the first one.

3. Change the page size.

4. The OnRead event is triggered twice.

Sample REPL for reproduction.
