Request either demo or functionality to either allow for "paging" of large scheduler data or functionality to utilize odata format for performance of scheduler data presentation.
My query even with just a year of data takes a few seconds to fetch from the database as well as several more seconds for the scheduler to process the data. Having functionality for changing views or switching days/weeks/months to allow for quick data updates from the back end would greatly improve overall performance.
The application users would like the scheduler to default to the work day view instead of the full day view.
Currently the only way to do this is to create a @ref to a property on my page and then override OnAfterRender to set the ShowWorkHours property to true. When examining the property I see that it is decorated with a HideFromApiRef attribute. Would it not be possible to change that to a Parameter so that the property could be set in the definition, or even bound to a variable?
If I change the width of the scheduler component it doesn't move the events to the correct place
I am currentl looking at printing the Scheduler but I ran into this issue when trying to adjust the scheduler to fit on a page
Hi there.
So I've been struggling for the last 2 days with the scheduler having this weird issue where setting it to Today's date set's the Scheduler's date correctly, but the incorrect date is shown in the date picker, with the correct date in the picker's popup.
I then went to the Scheduler overview screen and noticed the exact same bug there, so I'll be linking that page to show the issue along with an attached screenshot of the issue.

When adding / editing the last time slot for the day, SchedulerEditEventArgs has wrong End value.
For example Start value is 28.12.2023. 23:30:00 and end value is 28.12.2023. 00:00:00. Should instead be 28.12.2023. 23:59:59 or 29.12.2023. 00:00:00.
Hi,
I'm building a Grid which contains a nested Grid in it's `<DetailTemplate/>`.
When I'm opening the details, the grid events fire, the data gets loaded correctly but the data doesn't show up in the UI. Using .NET 8 Blazor with Telerik UI for Blazor Version 6.0.2.
This is the grid containing the Grid (data here gets loaded correctly):
<TelerikGrid @ref="@_grid" TItem="ChecklistDetailModel" Pageable Page="@_settings.CurrentPageNumber" PageSize="@_settings.Limit" OnRead="@OnPageReadAsync" Width="100%" Height="100%">
<GridToolBarTemplate>

<CountriesSelect Value="_settings.SelectedCountryId" OnChangeCallback="OnCountrySelected" Width="250px" />
<TelerikButton Icon="FontIcon.FileAdd" OnClick="OnCreateChecklistButtonClick" Title="@Localizer["ChecklistOverview.Create"]" />
</GridToolBarTemplate>
<GridColumns>
<GridColumn Title="ID" Width="50px">

@{
var model = checklist as ChecklistDetailModel;

</GridColumn>
<GridColumn Title="@Localizer["Data.ChecklistRevisionDate"]">
<Template Context="checklist">

var model = checklist as ChecklistDetailModel;
@if (model.LastUpdated.HasValue)

</TelerikGrid>This is the `CustomerChecklistGrid` code inserted into the DetailTemplate of the Grid above:

{
<GridCommandButton Icon="FontIcon.PaperPlane" OnClick="OnNavigateToCustomerChecklistButtonClickAsync" />
}
}
</GridCommandColumn>
</GridColumns>
</TelerikGrid>This is the backing C# code for the grid:
public partial class CustomerChecklistGrid
{
[Parameter] public int ChecklistId { get; set; }
[Parameter] public EventCallback<CustomerChecklistModel> OnEditCustomerChecklistButtonClick { get; set; }
[Parameter] public EventCallback<CustomerChecklistModel> OnNavigateToCustomerChecklistButtonClick { get; set; }
[Inject] public ICustomerChecklistService CustomerChecklistService { get; set; }
[Inject] public IStringLocalizer<SharedResources> Localizer { get; set; }
[CascadingParameter] public Routes App { get; set; }
private CustomerChecklistSettings _settings = new();
private PageResult<CustomerChecklistModel> _data = new();
private TelerikGrid<CustomerChecklistModel> _grid;
private async void OnPageReadAsync(GridReadEventArgs args)
{
var newOffset = args.Request.PageSize * (args.Request.Page - 1);
_settings.Offset = newOffset;
_settings.CurrentPageNumber = args.Request.Page;
var request = new CustomerChecklistRequestModel
{
Offset = _settings.Offset,
Limit = _settings.Limit,
ChecklistId = ChecklistId,
OrderBy = _settings.OrderBy,
IsCompleted = _settings.IsCompleted,
CustomerId = _settings.SelectedCustomerId
};
_data = await CustomerChecklistService.GetPageAsync(request);
args.Data = _data.Items;
args.Total = _data.Total;
StateHasChanged();
}
private void OnCustomerSelected(int customerId)
{
_settings.SelectedCustomerId = customerId;
_settings.CurrentPageNumber = 1;
_grid.Rebind();
}
private async Task OnEditCustomerChecklistButtonClickAsync(GridCommandEventArgs args)
{
var customerChecklist = args.Item as CustomerChecklistModel;
if (OnEditCustomerChecklistButtonClick.HasDelegate)
{
await OnEditCustomerChecklistButtonClick.InvokeAsync(customerChecklist);
}
}
private async Task OnNavigateToCustomerChecklistButtonClickAsync(GridCommandEventArgs args)
{
var customerChecklist = args.Item as CustomerChecklistModel;
if (OnNavigateToCustomerChecklistButtonClick.HasDelegate)
{
await OnNavigateToCustomerChecklistButtonClick.InvokeAsync(customerChecklist);
}
}
private sealed class CustomerChecklistSettings
{
public int Offset { get; set; }
public int Limit { get; set; } = 25;
public int CurrentPageNumber { get; set; } = 1;
public int? SelectedCustomerId { get; set; }
public bool? IsCompleted { get; set; }
public string OrderBy { get; set; } = "customer";
}
}This is a screenshot of the UI I'm seeing. I'm expecting data to show up in the inner grid, data gets loaded correctly (when debugging I see data is available), however no records are shown.
When I try to move by drag and drop an event between resources the resource on the event is not updated.
I used this
<TelerikScheduler Data="@_trips" Height="500px"@bind-Date="@StartDate"
IdField="@(nameof(TripInfo.Id))"
StartField="@(nameof(TripInfo.StartDateTime))"
EndField="@(nameof(TripInfo.EndDateTime))"
TitleField="@(nameof(TripInfo.BusCode))"
OnUpdate="@UpdateTrip"
OnDelete="@DeleteAppointment"
ConfirmDelete="true"
AllowDelete="true"
AllowUpdate="true"
DescriptionField="@(nameof(TripInfo.BusDescription))" @bind-View="@sv" @ref="@_scheduler">
<SchedulerSettings>
<SchedulerGroupSettings Resources="@GroupingResources" Orientation="@SchedulerGroupOrientation.Vertical"></SchedulerGroupSettings>
</SchedulerSettings>
<SchedulerViews>
<SchedulerTimelineView StartTime="@DayStart" ColumnWidth="20" SlotDivisions="6" SlotDuration="60" EndTime="@DayEnd" NumberOfDays="1" WorkDayEnd="@WorkDayEnd" WorkDayStart="@WorkDayStart" >
</SchedulerTimelineView>
</SchedulerViews>
<SchedulerResources>
<SchedulerResource Field="@(nameof(TripInfo.BusCode))" Title="Resources" TextField="@(nameof(BaseCodeInfo.Name))" ValueField="@(nameof(BaseCodeInfo.Code))" Data="@_resources"></SchedulerResource>
</SchedulerResources>
</TelerikScheduler>
Bug reproduced systematically on web browser Edge (131.0.29.03.146) & Firefox (134.0).
Beware: culture is fr-FR
Scheduler component sometimes put appointments at wrong coordinates (hour if ok but the day is wrong).
The screenshot "ExampleWrongCoordinates.png" set an example of an item wrongfully located. In this picture, console log shows details of the razor element who's supposed to be located on Tuesday 14th of January 2025 .. but which is rendered on Monday instead!
Appointments model defines "default (expected) property names Start & End":
private DateTime _start;
public DateTime Start
{
get { return _start; }
set { _start = value; }
}
private DateTime _end;
public DateTime End
{
get { return _end; }
set { _end = value; }
}View is MultiDay but the glitch is the same on Week view.
Now if we switch on day view and navigate to Tuesday 14, scheduler shows the appointment on hours column! If we click it, a JS error is raised (Cf screenshot "ClickAppointmentWrongCoordinates.png").
In the scheduler for Asp.net Ajax, the month view would put a k-other-month class on the cells from other months outside of the current one and those cells would have a different style (grayed day numbers or background, etc.). In the Blazor scheduler component it doesn't look like that class is being put on those cells anymore. The Telerik SCSS themes still allow for that class, so is there a way to add them or is there a workaround so that those cells can be re-styled similar to the way the Ajax Scheduler functions?
Thanks,
Mike
