At the moment, the focus remains on the cell. It should be in the input so the user does not have to perform an extra action (say, click with the mouse) in order to edit data.

This also applies to inserting a new row - the first cell should be focused.

<TelerikGrid Data="@GridData"
             FilterMode="Telerik.Blazor.GridFilterMode.FilterRow"
             SelectionMode="@GridSelectionMode.Multiple"
             @bind-SelectedItems="SelectedItems">
    <GridColumns>
        <GridCheckboxColumn Width="35px"/>
         <GridColumn Field="@(nameof(Data.Name))" />
     </GridColumns>
 </TelerikGrid>

@code{

    public class Data
    {
        public string Name { get; set; }
    }

    public List<Data> GridData { get; set; }
    public IEnumerable<Data> SelectedItems { get; set; }
    protected override void OnInitialized()
    {
        GridData = new List<Data>();
        SelectedItems = new List<Data>();
        GridData.Add(new Data{Name="abc"});
        GridData.Add(new Data{Name="abe"});
        GridData.Add(new Data{Name="xyz"});
    }
}

1. Filter the above grid by "abc" (the filtered grid will display "abc" correctly as the only entry)

2. Click into the "SelectAll" Checkbox (SelectedItems will wrongly contain "abc" AND "abe" !!!)

3. Click on "ClearFilter" Button --> the grid will display both "abc" and "abe" as selected !!!

It might be an indexing problem because the "SelectAll" Logic always seems to ignore the last character of the search string while the filtering of the display takes all characters into account.

This bug has cost be many hours and stomach pain!  Please let me know, if this will be fixed soon.  If not I will have to implement my own filtering (which makes me wonder why I'm using Telerik UI).

I am editing parent and child records in the hierarchy grid.  I can edit parent and child records without issue.  The only problem I have now is this; when I click edit on a child record, then collapse the parent, the edit of the child record is lost or cancelled but there is no event I can see to use to put things back in non-edit mode.

I enable buttons and links in non-edit (view) mode and disable them when editing a record.

So,  is there an event or some way to know the user is collapsing or expanding a parent record?

Thank you,

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

I would like the grid to behave like Excel for editing, and so I am using the InCell editing mode. I would like that pressing Tab would open the next cell in the row instead of moving the focus to the next focusable element.

ADMIN EDIT

The feature is rather complex and we want to make sure it is done right. To this end, we have postponed its implementation for the year 2021 instead of the November 2020 release. When a concrete release is known, this page will be updated. To get notifications for that, click the Follow button.

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; }
    }
}

When you scroll to the right in a grid and filter so that there are no items, the horizontal scroll disappears and you can no longer come back to the filter in order to clear it and work with the grid again.

The GroupFooterTemplate works great for showing aggregate values per group.

Need the same functionality for the entire Grid, ie, sum of all values displayed for a column even if no grouping is applied.

There is an issue with setting the Grid's Page property to values other than 1.

This is visible on the Blazor Demo for Grid Paging (https://demos.telerik.com/blazor-ui/grid/paging).

Initially the CurrentPage variable is set to 3, and thus the Page property on the Grid is set to 3. The Pager in the grid correctly shows Page 3 and the Pager Info is also correct, however, the data in the Grid is not filtered to the correct page. This can be seen by clicking Page 1 in the Pager (the data remains the same), and then clicking Page 3 in the Pager (the data changes, and is different than the initial data).

Please add a property to the grid that lets me specify a debounce time for filtering. This way I can (for example) set the debounce time to 500(ms), and then only have the grid filter (which is slow) when the user stops typing (it current takes about 300ms per keypress anyway).

ADMIN EDIT

We are reopening this feature request because it can make sense for the FilterRow filter mode as an out-of-the-box feature, even if it can be achieved right now with a bit of application code (example).

---

An autofit feature would be useful which sizes a column according to fit the current content exactly (with some space on the left and right ;-)

* autofit attribute for a column to automatically autofit the column

* autofit method on a grid column to issue autofit by code

Autofit for entire table (nice to have)

* autofit attribute on the grid element to automatically autofit all its columns (except those explicitely set to AutoFit="false")

* autofit method on a grid to issue autofit by code

Please add an attribute to Blazor GridColumn which allows to easily format data with the default .NET standard formats

e.g. <GridColumn Field="@(nameof(Item.Price))" Title="Price" Format="0#.##" />

It's a little bit annoying always having to define a template for this purpose.

Please add an attribute to Blazor GridColumn which allows to easily align text horizontal in a GridColumn

e.g. <GridColumn Field="@(nameof(Item.Price))" Title="Price" HorizontalAlignment="Right" />

At least: Left, Right, Center

It is a common request to show grids in alternating colors, rather than simply white and grey.  Because the Grid component generates the <tr> element, we are left with manually setting each <td> element.  A tedious but effective solution.

The feature I would like to request is to add 2 new tags to the <TelerikGrid> component, call them EvenRowClass, and OddRowClass.  The behavior is the same as the Class tag, but they operate on Even and Odd numbered rows of data, respectively.  Their values would be added to the <tr> element as <tr class="MyEvenClass"> or <tr class="MyOddClass" in the same manner class k-alt is generated or not.  This would provide a simple yet extensible mechanism to achieve custom alternating row colors in a Grid.

Can you add a confirmation popup to the grid row delete like what is in the JQuery UI library?

---

ADMIN EDIT

As of 2.23.0 predefined confirmation dialog is available for use with just a few lines of code and you can achieve that behavior through the OnClick event of the command button:

<TelerikGrid Data=@GridData EditMode="@GridEditMode.Inline"
             Height="500px" AutoGenerateColumns="true" Pageable="true"
             OnDelete="@DeleteItem">
    <GridColumns>
        <GridAutoGeneratedColumns />

        <GridCommandColumn Width="100px">
            <GridCommandButton Command="Delete" Icon="delete" OnClick="@ConfirmDelete">Delete</GridCommandButton>
        </GridCommandColumn>

    </GridColumns>
</TelerikGrid>

@code {
    //for the confirmation - see the OnClick handler on the Delete button
    [CascadingParameter]
    public DialogFactory Dialogs { get; set; }

    async Task ConfirmDelete(GridCommandEventArgs e)
    {
        Product productToDelete = e.Item as Product;
        string confirmText = $"Are you sure you want to delete {productToDelete.Name}?";
        string confirmTitle = "Confirm Deletion!";
        //the actual confirmation itself
        bool userConfirmedDeletion = await Dialogs.ConfirmAsync(confirmText, confirmTitle);
        e.IsCancelled = !userConfirmedDeletion;//cancel the event if the user did not confirm
    }

    // only sample data operations follow

    public List<Product> GridData { get; set; }

    protected override async Task OnInitializedAsync()
    {
        GridData = Enumerable.Range(1, 50).Select(x => new Product { Id = x, Name = $"Name {x}" }).ToList();
    }

    private void DeleteItem(GridCommandEventArgs args)
    {
        Console.WriteLine("DELETING ITEM");
        var argsItem = args.Item as Product;

        GridData.Remove(argsItem);
    }

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