We find this in our infrastructure but it can be reproduced even in Telerik docs.

Docs page: https://docs.telerik.com/blazor-ui/components/grid/grouping/overview try to drop all three columns using drag and drop in sequence: Team, Name, On Vacation.

Expected sequence: Team, Name, On Vacation

Expected sequence: Team, On Vacation, Name

All Elements are always added as 1 item. It is an important feature for us, as our customers use it frequently.

TELERIK EDIT:

A possible workaround is to intercept the grouping and reorder the groups:

@using Telerik.DataSource

<p>Group by a third column, so that it should come last in the Group Panel:</p>

<TelerikGrid @ref="@GridRef"
             Data="@GridData"
             Pageable="true"
             Sortable="true"
             Groupable="true"
             FilterMode="GridFilterMode.FilterRow"
             OnStateInit="@( (GridStateEventArgs<Employee> args) => OnGridStateInit(args) )"
             OnStateChanged="@( (GridStateEventArgs<Employee> args) => OnGridStateChanged(args) )">
    <GridColumns>
        <GridColumn Field="@nameof(Employee.Name)" />
        <GridColumn Field="@nameof(Employee.Team)" />
        <GridColumn Field="@nameof(Employee.Salary)" />
        <GridColumn Field="@nameof(Employee.OnVacation)" />
    </GridColumns>
</TelerikGrid>

@code {
    private TelerikGrid<Employee>? GridRef { get; set; }

    private List<Employee> GridData { get; set; } = new();

    private void OnGridStateInit(GridStateEventArgs<Employee> args)
    {
        args.GridState.GroupDescriptors = new List<GroupDescriptor>();

        args.GridState.GroupDescriptors.Add(new GroupDescriptor()
        {
            Member = nameof(Employee.Team),
            MemberType = typeof(string)
        });

        args.GridState.GroupDescriptors.Add(new GroupDescriptor()
        {
            Member = nameof(Employee.OnVacation),
            MemberType = typeof(bool)
        });
    }

    private async Task OnGridStateChanged(GridStateEventArgs<Employee> args)
    {
        if (args.PropertyName == "GroupDescriptors" && args.GridState.GroupDescriptors.Count > 2 && GridRef != null)
        {
            var secondGroupDescriptor = args.GridState.GroupDescriptors.ElementAt(1);

            args.GridState.GroupDescriptors.Remove(secondGroupDescriptor);
            args.GridState.GroupDescriptors.Add(secondGroupDescriptor);

            await GridRef.SetStateAsync(args.GridState);
        }
    }

    protected override void OnInitialized()
    {
        var rnd = new Random();

        for (int i = 1; i <= 20; i++)
        {
            GridData.Add(new Employee()
            {
                Id = i,
                Name = "Name " + i,
                Team = "Team " + (i % 4 + 1),
                Salary = (decimal)rnd.Next(1000, 3000),
                OnVacation = i % 3 == 0
            });
        }
    }

    public class Employee
    {
        public int Id { get; set; }
        public string Name { get; set; } = string.Empty;
        public string Team { get; set; } = string.Empty;
        public decimal Salary { get; set; }
        public bool OnVacation { get; set; }
    }
}

When is Spreadsheet for Blazor available or can i use Kendo Spreadsheat?

Hi,

I haven't been able to find this as a request or as a topic of discussion (If it iss feel free to point me to it and close this request) but I feel the Grouping feature is limiting. If I use the group field in say the DropDownList the grouping works fine but it orders it alphabetically.

I propose adding a number of features to enhance this. The first being a GroupAscending or GroupDescending tag. Takes a boolean value and allows you to change the order to ascending (default/True) or descending (False).

The second, and more complicated feature upgrade could be a GroupOrder tag. This would take a List of the group field names ordered in the way you require and apply that order to the grouping in the DropDownList. for instance if you had the list ordered as Category 1, Category 3, Category 2 it would display the items in each grouping in that order top to bottom.

Regards,

Luke

Provide ability to define icons for input prefix and suffix. Thus, provide mechanism for built-in validation icon as well.

Example image with suffix icons to give you better perspective of the feature.

The Theme Builder contains a really nice looking Popover control, and I was a bit disappointed to discover that this doesn't seem to be documented or supported in UI for Blazor.

I realize I can probably use the Tooltip to achieve a similar effect, with two caveats:

1. Tooltip requires of substantial CSS hacking to appear as the Popover control.
2. The Popover closes on an explicit event, whereas Tooltip closes when it loses focus.

Is there any chance a Popover control is planned for a future release?

Hi Telerik Support.

I am using TelerikComboBox with Virtualization and enabled Filtering.  If I filter for a text and then scroll down, the filter text gets cleared. I am using OnRead event to populate the combo box. But the same issue is seen with local data population in the below sample code.

https://demos.telerik.com/blazor-ui/combobox/virtualization

I need to show the user the text they have entered even when they scroll down to the next page. Is there a solution for this? 

Regards

Please Add DropDown Container so it will be possible to add Nested Custom Editors inside Grid Cell

Regards

Andrzej

ADMIN EDIT

A dropdown container we would create would be a popup that ties to its anchor and gives you a template to render your own content rather than render its own items based on Data. It cannot, however, be tied to a specific case for a grid or other editor, it will be up to the developer to use the container and tie it to the application logic.

It should also expose events like PopupShowing (preferred to also cater for keyboard navigation) or ExpandClick so you can know when it is going to be expanded and, for example, fetch fresh data for scenarios with highly volatile data (example here).

So, brand new machine (Win 11 pro 64bit), brand new install of Visual Studio & Telerik, use the Telerik templates to create a new Blazor Server project.

When I run the application (with changes or first run), it takes almost a minute to start the application.

Without changes it starts in 2 seconds.

The fix is to add the following to the application's csproj file.

  <PropertyGroup>
    <UseRazorBuildServer>false</UseRazorBuildServer>
  </PropertyGroup>

After the fix, it takes an just a little longer to run than without changes.  Since I have not heard back on my support ticket, I wanted to report this as a bug so hopefully it can get upvoted and we can get an answer to this issue. 

Original support ticket https://www.telerik.com/account/support-center/view-ticket/1621737 

My Setup:

7950x, 32 gb DDR5 ram, WD Black SSD 850x SSD and slower internet 150mbit/s

Similar problem with my new laptop which is about 50% slower but exactly the same issue.

When you edit in Telerik Repl, you get a warning message:

What was weird though, is when I ran it from directly from the link in the documentation, I didn't get an error.  I made one small change to the code (swapped line 54 and 55 (just seeing if I could change the rendering order, which I can) and then I saw this warning.  But any change to the code generates the warning.

When you click "Preview" under Using TelerikFontIcon, the preview is blank, even if I scroll to the top, still nothing.

I would like to use the new structs that are part of .NET6 - the DateOnly and TimeOnly. 

Their support should extend to all respective date and time pickers and more complex components like the Grid, Gantt, Scheduler, and other applicable components. 

Hi

I don't understand the text in this yellow info box: "You can define a key for zooming only selection zooming is configured." Is there a word missing?

https://docs.telerik.com/blazor-ui/components/chart/pan-and-zoom/zoom#specifying-a-key-for-zooming

https://docs.telerik.com/blazor-ui/knowledge-base/inputs-validation-child-component

Number of typos where "Fied" should be "Field".  

1 minute fix, just looks bad.  4x in MyCustomComponent and in MainComponent.

Is a ListBox control, similar to https://demos.telerik.com/aspnet-core/listbox/index, on the roadmap currently?

---

ADMIN EDIT

You can use a grid that has 1 column for the text you want to show with selection and perhaps even row dragging, and maybe hide its headers with css if you do not want them.

https://docs.telerik.com/blazor-ui/components/grid/paging

Under the section "Bind Page Size to a variable", if you click preview it generates an error.
