Filtering after a partial Guid value not working on TelerikGrid

We are using a TelerikGrid which allows to filter various properties.

One of our properties is a name of Id, which is of Guid type.

Of course when we give a full Guid Id into the filter, the filter works, but as soon as we put a partial Guid value the filter breaks, because as expected, it cannot parse the given value.

Error: System.FormatException: Unrecognized Guid format.
at System.Guid.GuidResult.SetFailure(ParseFailure failureKind)
at System.Guid.TryParseGuid(ReadOnlySpan`1 guidString, GuidResult& result)
at System.Guid..ctor(String g)

We have tried to convert guid value into string and then pass it into the filter, but it expects a Guid data type.

Is there a way to internally let the guid filter know, that he should expect a string value instead of Guid? Filtering after Guid doesn't really make sense, since user will most of the time just type a part of the full guid Id value.

Thank you for assistence!

Hello, I'm currently working on implementing inline editing for the first five rows of a Telerik Grid for blazor upon a button click. Is it possible to achieve this, and if so, could you please provide guidance on how to do it? The button triggering the inline editing functionality is placed outside the grid.

Thank you

Svg icons in html markup

Hello,

Until recently, I was using font icons in html markup (k-icon, k-i-imagename), but with a recent update to Telerik for Blazor 5.1.1, these do not work anymore. For components which have a Icon property, I simply replace the FontIcon references with SvgIcon.

However, for icons referenced in markup, I'm not able to get the icons to display, as suggested in Changes in Icon Rendering.

Please advise.

Thank you.

[Notification] When the page jumps, the appearance position of the Notification component is reset.

Hi,

When the page jumps, the appearance position of the Notification component is reset.

My project code：

public static async Task ShowSuccessNotification(string message = "Success",int closeAfter = 60000,object icon = null,AnimationType animationType = AnimationType.Fade,NotificationHorizontalPosition horizontalPosition = NotificationHorizontalPosition.Center, NotificationVerticalPosition verticalPosition = NotificationVerticalPosition.Top)
{
    if (NotificationReference != null)
    {
        NotificationReference.Animation = animationType;
        NotificationReference.HorizontalPosition = horizontalPosition;
        NotificationReference.VerticalPosition = verticalPosition;
        NotificationReference.Text = message;
        NotificationReference.CloseAfter = closeAfter;
        NotificationReference.Icon = icon;
        await NotificationReference.ShowSuccess();
    }
}

Notification Component Code(.razor)：

@using Telerik.Blazor
@using Telerik.Blazor.Components

<style>
    .custom-notification-parent {
        position: fixed;
        left: 50%;
        top: 20px;
        transform: translateX(-50%);
        z-index: 99999999;
    }

    .custom-positioned-notifications {
        position: relative;
        flex-wrap: nowrap !important;
    }

    .k-notification {
        box-shadow: var(--kendo-elevation-4, 0 8px 10px rgba(0, 0, 0, 0.12), 0 4px 16px rgba(0, 0, 0, 0.12));
        font-size: 16px;
    }
</style>

<div class="custom-notification-parent">

                         HorizontalPosition="@HorizontalPosition">
    </TelerikNotification>
</div>

@code {

Notification Component Code(.razor.cs)：

public partial class Notification
    {
        private TelerikNotification notification { get; set; }

                CloseAfter = CloseAfter,
                Icon = Icon
            });
        }

        public async Task ShowError()

                ThemeColor = ThemeConstants.Notification.ThemeColor.Error,
                CloseAfter = CloseAfter,
                Icon = Icon
            });
        }

        public async Task ShowWarning()
        {
            notification.Show(new NotificationModel
            {
                Text = Text,
                ThemeColor = ThemeConstants.Notification.ThemeColor.Warning,
                CloseAfter = CloseAfter,
                Icon = Icon
            });
        }

        public async Task ShowInfo()
        {
            notification.Show(new NotificationModel
            {
                Text = Text,

            });
        }

        protected override async Task OnInitializedAsync()
        {
            await base.OnInitializedAsync();
            AlertController.SetNotificationReference(this);
        }
    }

Calling code：

try
{
    var response = await CoreDataSource.Request(bulkRequest);

    await AlertController.ShowSuccessNotification("[Complete Work Task]:Success");
    NavigationController.Navigate(new WorkViewParam());
}
catch (Exception e)
{
    await AlertController.ShowWarningNotification("[Complete Work Task]:" + e.Message);
}

Customize the expander in TelerikTreeView using TelerikToggleButton

How can I replace the default carat expander of the TelerikTreeView with a customized expander using a TelerikToggleButton? I'd like to toggle between two ISvgIcons as my expand and collapse.

What I'm trying to accomplish is very similar to what's being done in this example with RadTreeView and ToggleButton https://docs.telerik.com/devtools/wpf/controls/radtreeview/styles-and-templates/styling-and-appearance-styling-expander.

How to get the rendered dates from a scheduler view

I need to know how I can get all the rendered dates from the scheduler for the current view? I know that I have the data that I provide to the scheduler, but I am really concerned with recurring events. For a recurring appointment that is provided to the scheduler data, it could render up to six unique events. I am trying to get a list of those event.

I tried the OnCellRender event which iterates thru all the days on the scheduler, but there is nothing in the event data to identify if an appointment was rendered on that day or not.

I tried the OnItemRender event which iterates thru the appointments on the view, but for the recurring events it always gives the date in the defined appointment not the actual date that it was rendered.

For a use case, I want to use a Calendar to show a minified version of active days in a month. Since some of the events are recurring, I cannot just use the appointment data. I would like to give it to the scheduler and let the scheduler tell me what days are rendered as a result of the provided appointments.

For this appointment list, I should get the following dates returned:
5/2, 5/9, 5/16, 5/23, 5/30, 6/6, 5/25, 5/26

new SchedulerAppointment
{
	Title = "Vet visit",
	Description = "The cat needs vaccinations and her teeth checked.",
	Start = new DateTime(2024, 5, 2, 11, 30, 0),
	End = new DateTime(2024, 5, 2, 12, 0, 0),
	IsAllDay = false,
	RecurrenceExceptions = new List<DateTime>(),
	RecurrenceId = Guid.NewGuid(),
	RecurrenceRule = "FREQ=WEEKLY;BYDAY=TH"
}

new SchedulerAppointment
{
	Title = "Planning meeting",
	Description = "Kick off the new project.",
	Start = new DateTime(2024, 5, 25, 9, 30, 0),
	End = new DateTime(2024, 5, 25, 12, 45, 0)
}

new SchedulerAppointment
{
	Title = "Vet visit",
	Description = "The cat needs vaccinations and her teeth checked.",
	Start = new DateTime(2024, 5, 26, 11, 30, 0),
	End = new DateTime(2024, 5, 26, 12, 0, 0)
}
