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.

I want to place the Pager on top of the Grid. I know it can be handled with a Pager component integration in the Grid Toolbar, but I want to use the Toolbar for other purposes/actions. Please allow control over the Pager position.

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.

Hello,

When a Grid is using multi column headers, and I add one more column in the OnBeforeExport event, this new column has no title in the exported file.

A possible workaround might be to use a column with zero Width and change the width in OnBeforeExport.

@using Telerik.Blazor.Common.Export.Excel
@using Telerik.Blazor.Components.Grid

<TelerikGrid TItem="@FlowRun"
             Pageable="true"
             OnRead="@GetData">

    <GridToolBar>
        <GridCommandButton Command="ExcelExport" Icon="file-excel">Export to Excel</GridCommandButton>
        <GridCommandButton Command="CsvExport" Icon="file-csv">Export to CSV</GridCommandButton>
        <label class="k-checkbox-label"><TelerikCheckBox @bind-Value="@ExportAllPages" />Export All Pages</label>
    </GridToolBar>

    <GridExport>
        <GridExcelExport FileName="telerik-grid-export" AllPages="@ExportAllPages" OnBeforeExport="@BeforeExcelExport" />
        <GridCsvExport FileName="telerik-grid-export" AllPages="@ExportAllPages" OnBeforeExport="@BeforeCsvExport" />
    </GridExport>

I have the following situation. I'm using a custom editor template with two-way binding for the  column : OrderToEdit.ShipCity. If I change the value of this column in a row and press Enter, Tab or mouse focus out very quickly (immediately after value change),  UpdateHandler is triggered before the valueChanged event of the context and as a result changes are not shown. If there is a delay ( i.e 1 second ) all works fine. This is not happening when i'm using the builtin editor GridEditorType.TextBox. Could you provide me a solution ? 

There is another problem. if a click inside a cell edit mode is triggered. But if i click in a button in the toolbar or in column menu the cell remains open is not closed. I think this should not happen.
