Hello Telerik,

I want to confirm this is the recommended way to create the Default Sort Order for a Grid.

Thank you.

TelerikGrid Data="@MyData" Sortable="true" AutoGenerateColumns="true"
             OnStateInit="@((GridStateEventArgs<SampleData> args) => OnStateInitHandler(args))">
</TelerikGrid>

@code {
    async Task OnStateInitHandler(GridStateEventArgs<SampleData> args)
    {
        var state = new GridState<SampleData>
        {
            SortDescriptors = new List<Telerik.DataSource.SortDescriptor>
            {
                new Telerik.DataSource.SortDescriptor{ Member = "LastModified", SortDirection = Telerik.DataSource.ListSortDirection.Descending }
            }
        };

        args.GridState = state;
    }

    public IEnumerable<SampleData> MyData = Enumerable.Range(1, 5).Select(x => new SampleData
    {
        Id = x,
        LastModified = new DateTime(2022, x, 28)
    });

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

        public DateTime LastModified { get; set; }
    }
}

Gird Column Menu not working

Hello,

I am trying to use the Grid Column Menu and even the most basic example from the docs throws an error or just freezes the page. I am using the latest version of Telerik (6.0.2) I already have other Telerik Grids and components working well in another pages. Here is the link from the docs.

Here is the code in my page:

@page "/tests"
@rendermode InteractiveServer

<h3>Testing</h3>

<TelerikGrid Data="@GridData"
Pageable="true"
PageSize="5"
FilterMode="@GridFilterMode.FilterMenu"
Sortable="true"
ShowColumnMenu="true">
<GridColumns>
<GridColumn Field="@(nameof(SampleData.Id))" Width="80px" />
<GridColumn Field="@(nameof(SampleData.Name))" Title="Employee Name" Groupable="false" />
<GridColumn Field="@(nameof(SampleData.Team))" Title="Team" />
<GridColumn Field="@(nameof(SampleData.HireDate))" Title="Hire Date" />
</GridColumns>
</TelerikGrid>

@code {
private IEnumerable<SampleData> GridData = Enumerable.Range(1, 30).Select(x => new SampleData
{
Id = x,
Name = "name " + x,
Team = "team " + x % 5,
HireDate = DateTime.Now.AddDays(-x).Date
});

public class SampleData
{
public int Id { get; set; }
public string Name { get; set; }
public string Team { get; set; }
public DateTime HireDate { get; set; }
}
}

How can I create a better looking notification?

I would like to create a notification that looks like this.

I like that it has a header and a body. Also that the alert color is bound to the icon

As I see it I need some container elements to pull it off, but I am in no way a css expert 😉

here is the html generated by Telerik

<div class="k-notification k-notification-secondary k-notification-closable">
  <span class="k-notification-status k-icon k-svg-icon k-svg-i-info-circle">
    <svg aria-hidden="true" focusable="false" xmlns="http://www.w3.org/2000/svg" viewBox="0 0 512 512">
      <path d="M288 352h32v32H192v-32h32v-96h-32v-32h96zm0-224h-64v64h64zm192 128c0 123.7-100.3 224-224 224S32 379.7 32 256 132.3 32 256 32s224 100.3 224 224m-32 0c0-106-86-192-192-192S64 150 64 256s86 192 192 192 192-86 192-192">
      </path>
    </svg>
  </span>
  <div class="k-notification-content">
    Notification
  </div>
  <span class="k-notification-actions">
    <span class="k-notification-action k-notification-close-action">
      <span class="k-icon k-svg-icon k-svg-i-x">

Disabled Dates not honored with date range

Using the following example: https://blazorrepl.telerik.com/mIODuTlt02gFnIYp00

What I am trying to accomplish is the following:

I want the user to be able to pick a start date and end date using the range selector, if there are disabled dates between the range, the range should not be accepted since one or more of the dates are disabled.
