This isn't a bug per say, but with the latest Telerik Blazor update, the GridCommandEventArgs Field and Value properties are now deprecated.  When updating a specific cell in a grid using InCell edit mode, how am I able to know which specific field and value are updated when the OnUpdate event gets called?  Before the latest update, I had the following code:

protected override void OnGridRowUpdate(GridCommandEventArgs args)
        {
            validationMessage = ValidateField(args.Field, args.Value);

        }

I realize I have the updated values using args.Item, but I don't want to have to validate the entire row every time I update a cell.  Is there still a way to know what cell I updated, or is that information no more?

Thank you,

Steve

The grid should support INotifyPropertyChanged for the objects in the grid, i.e. if the data object implements INotifyPropertyChanged and a property value changes, the corresponding cell value in the grid should also change.

Description

When the Grid/TreeList is in incell edit mode and you finish editing a cell by pressing "Enter", the focus is lost if the next cell to be edited is not editable.

Reproduction (if bug)

Steps to reproduce:

1. Use the code

@using System.ComponentModel.DataAnnotations;

<TelerikGrid Data="@forecasts"
             Height="550px"
             FilterMode="@GridFilterMode.FilterMenu"
             Sortable="true"
             Pageable="true"
             PageSize="20"
             Groupable="true" Resizable="true"
             Reorderable="true"
             EditMode="@GridEditMode.Incell">
    <GridColumns>
        <GridColumn Field="Id" Title="Id" Width="100px" Editable="false" Groupable="false" />
        <GridColumn Field="Summary" Id="summary" Title="telerik bind-Value">
            <Template>
                @{
                    var model = context as WeatherForecast;
                    <span>@model.Summary</span>
                }
            </Template>
            <EditorTemplate>
                @{
                    var model = context as WeatherForecast;
                    if (model.CanEdit)
                    {
                        <TelerikTextBox @bind-Value="@model.Summary"></TelerikTextBox>
                    }
                    else
                    {
                        @model.Summary
                    }

                }
            </EditorTemplate>

        </GridColumn>

    </GridColumns>
</TelerikGrid>

@code {
    List<WeatherForecast> forecasts { get; set; }

    protected override void OnInitialized()
    {
        forecasts = WeatherForecast.GetForecastList();
    }

    public class WeatherForecast
    {
        public int Id { get; set; }

        public string Summary { get; set; }

        public bool CanEdit { get; set; }


        static public List<WeatherForecast> GetForecastList()
        {
            var rng = new Random();
            return Enumerable.Range(1, 150).Select(index => new WeatherForecast
            {
                Id = index,
                Summary = Summaries[rng.Next(Summaries.Length)],
                CanEdit = index % 3 != 0

            }).ToList();

        }

        private static readonly string[] Summaries = new[]
        {
            "Freezing", "Bracing", "Chilly", "Cool", "Mild", "Warm", "Balmy", "Hot", "Sweltering", "Scorching"
        };
    }
}

2. Click on the second column of row 1.
3. After the cell editor is opened, press "Enter"

Broken Telerik UI for Blazor version (if bug)

x.y.z

Last working version of Telerik UI for Blazor (if regression)

If you reorder a column and then lock it, visually it looks locked and the functionality for a locked column is correctly supported.

However, the Locked property of the ColumnStates in Grid State for that column remains "false". Locked = "true" is applied based on the initial column position.

Currently, when navigation is used with virtual columns and locked columns, clicking on a cell, scrolls the cell to the center. The behavior was designed to have consistent interaction with either mouse, or keyboard. However, for mouse interaction such scrolling and changing the cell position according to the mouse cursor is not intuitive.

This bug report will target the scenario with mouse click for cells that are not overlapped by locked columns - they will not be scrolled to the center.

Try to dynamically switch between Scrollable and Virtual modes. You would need to manually refresh the Skip property through the Grid state, or it won't work.

-----------ADMIN EDIT------------

You can use the ValueChanged handler to manually refresh the Skip property as shown below.

public TelerikGrid<ExpandoObject> TelerikGrid { get; set; }

private bool IsPageable = false;

private int Page { get; set; }

public void ChangeHandler(bool value)
{
    //Sync the paging with scrolling

    if (value)
    {
        IsPageable = value;
        var state = TelerikGrid.GetState();
        state.Skip = 0;
        state.Page = 3;

        _ = TelerikGrid.SetState(state);
    }

    IsPageable = value;

    StateHasChanged();
}

When exporting data from a Grid using ExcelExport, the dates are visible when viewed from Excel, but not when using Open Office or Google Sheets. 

Hi,

Is it possible to add a sub menu, in column menu so that the end user can add an aggregate operation (Sum, average...) on any column he wants and the foot panel will be automatically displayed or hidden.

Yours,

Hi,

Please lunch your demo on mobile, and try resizing a column it is very hard or impossible to do it.

Isn't possible to make resizing more pixel sensible around the separator for instance 10 pixels, and add AUTO FIT column/columns in column menu.  

Best regards,
