https://docs.telerik.com/blazor-ui/components/filemanager/events#read-event

The documentation says the event can be used "for example, to retrieve only a small number of items to improve the backend performance." This is exactly the scenario I have with many files and folders. However, the event only seems to fire one time when the control is initialized.

What is the purpose of this event, since data can be read programmatically with the OnInitializedAsync or OnModelInit events?

Is there any way to set the data to the current path's folders/files and use the read event when the user navigates (up or down) to a new folder?

Thanks

I love the GridLayout-Component. I use it a lot.

I mostly set the Grid Parameter "VerticalAlign" to Center. But that is for all the Cells in the Grid.

But sometimes I want to set the Alignment of just one Cell to e.g. "Top".

How is that possible ? It would be a great feature having this Property for each GridItem...

I just discovered the DetailTemplate and it is great. But I build myself a genereric Grid-Control with the Tererik-Grid and I pass a RenderFragement from my Parent-Component to this Control. This works perfectly. But even if the RenderFragemt is Null, the "+" and "-" Buttons to expand and collaps the DetailTemplate are always shown. How can I hide them ?

Unfortunately this is not working:

    @if (ChildContent != null)
    <DetailTemplate>
        {
            @ChildContent
        }
    </DetailTemplate>
    }

Hi All,

I schedule a Month at the time but using the MultiDay view because I need 09:00-17:00 in .25 hours a day.

Is it possible to use the Month view in a grid of days x hours like the Multiday view.

As alternative I would also be happy if I could use the Month-view date-picker 

 

TIA

Regards, Maarten

I would like to achieve this:

I have a GridLayout width 3 Rows (50px, Auto, 50px)

The second row is expanding due to the Browser-Height.

Inside this second Row I would like to put a Grid that expands along to the maximum available height when the User resizes the Browser.

If I give the Grid the Height of "100%" the Height is too low if the Grid has no rows. I would like to expand the Grid always to the maximum available space. At the moment I try to calculate the height with JavaScript in Pixel but I hope that there would be a better way !?

Is there any ?

I'm using

ChartCategoryAxis Type="@ChartCategoryAxisType.Date" BaseUnit="@ChartCategoryAxisBaseUnit.Fit"

Is there a way to show the labels as DayOfWeek (Wednesday) instead of date (3/1) ?

Copied a demo TelerikScheduler:
<TelerikScheduler Data="@RFCactions"
                  @bind-Date="@StartDate"
                  Height="600px" 
                  @bind-View="@CurrView"
                  AllowCreate="false" AllowDelete="false" AllowUpdate="false"
                  ConfirmDelete="true"
                  IdField="@(nameof(RequestForChangeActionSched.Id))"
                  StartField="@(nameof(RequestForChangeActionSched.StartingDate))"
                  EndField="@(nameof(RequestForChangeActionSched.EndingDate))"
                  IsAllDayField="@(nameof(RequestForChangeActionSched.IsAllDay))"
                  TitleField="@(nameof(RequestForChangeActionSched.RequestForChangeId).ToString())"
                  DescriptionField="@(nameof(RequestForChangeActionSched.Activity))">
    <SchedulerViews>
        <SchedulerDayView StartTime="@DayStart" EndTime="@DayEnd" WorkDayStart="@WorkDayStart" WorkDayEnd="@WorkDayEnd" />
        <SchedulerWeekView StartTime="@DayStart" EndTime="@DayEnd" WorkDayStart="@WorkDayStart" WorkDayEnd="@WorkDayEnd" />
        <SchedulerMultiDayView StartTime="@DayStart" EndTime="@DayEnd" WorkDayStart="@WorkDayStart" WorkDayEnd="@WorkDayEnd" NumberOfDays="31" SlotDivisions="4" >
            <DateHeaderTemplate>
                <div>
                    @context.ToString("ddd dd")
                </div>
            </DateHeaderTemplate>
        </SchedulerMultiDayView>
        <SchedulerMonthView></SchedulerMonthView>
        <SchedulerTimelineView StartTime="@DayStart" EndTime="@DayEnd" WorkDayStart="@WorkDayStart" WorkDayEnd="@WorkDayEnd" />
    </SchedulerViews>
</TelerikScheduler>

@code {
    List<RequestForChangeActionSched> RFCactions = new List<RequestForChangeActionSched>();
    ....etc
Made sure all required fields are in my model, with the same datatypes
But the (any) view won't show because of an InvalidCastException
Updated from V2023.1.313.33 to V2023.1.426.51 but still got the cast error at blazor.webassembly.js:1  

System.InvalidCastException: Specified cast is not valid.

I have a grid that loads big data. We used to use the ObservableCollection but opted to use the OnRead for better performance (loading takes time when using ObservableData). We have EventAggregators and PropertyChanged events running async OnInitialised().. Does this affect the OnRead event? We manually track the Add, Edit/Update, Delete and Duplicate actions on the grid.

So upon running our blazor app, the grid won't load the data on the grid and has the loading animation on endless loop. (Tried waiting for it to load for about 2 hours). Also tried debugging line per line from which I saw that upon executing the OnRead, the args,Data and args,Total were popullated properly.
