I've created a custom GridColumn component with special formatting like so:

<GridColumn Field="@Field" Title="@Title" Width="@Width">

   <Template Context="context">

       @FormatValue(context)

   </Template>
</GridColumn>


When I place this within a <GridColumns> element (within a <TelerikGrid>) it always appears last. I'm pretty sure it's related to this issue but I don't quite follow the solution. The first one says to put the custom component directly in the grid tag. As in directly under <TelerikGrid> rather than within <GridColumns> (where I have it now)?

I having the same issue with a custom <DropDownMenuItem> component in that it always appears last no matter where I place it within the <DropDownButtonItems> in a <TelerikDropDownButton>. This isn't quite as critical because all of my button items are custom components so I can arrange them properly. But the GridColumn is mixed with other normal GridColumn components and I'd rather not have to create custom components for all of them.

Any thoughts? This is .NET 9 with Telerik UI for Blazor 7.1

Hi

I'm using the TelerikMenu component with multiple nested levels of menu items. When moving the cursor from inside a nested level, to a parent level that is not in the currently selected path, the menu disappears. 

View this example on REPL: https://blazorrepl.telerik.com/mIvFOglY481u2hRG05

When moving the cursor from "Item A1 - 1" to "Item A2", the menu disappears.

Because I have a large menu with multiple levels, it would improve user experience to keep the menu visible as long as the cursor hovers it. Is there any way to make this happen?

Best regards

Bram

How can I get the start and end dates that are displayed in the current view?  I understand that there is a date changed event, but that doesn't give me the entire date range of what is currently being displayed.  I'd like to use that date range to then re-query the database and only pull back the events for that specific range.  I currently can't find a way to get that information.

I'm trying to read from an existing Excel file that the user will upload via FileSelect.   When it gets to the last line trying to set the workbook variable:

workbook = formatProvider.Import(selectedFile.Stream, TimeSpan.FromSeconds(30));

...I get the error, "'System.NotImplementedException' in Telerik.Zip.dll: 'Synchronous actions on the file stream is not supported by the Blazor framework in Blazor Server-side apps due to the SignalR communication between the client and the host. Use the 'ReadAsync' method instead.'"

If I try to copy the stream first like this:

await selectedFile.Stream.CopyToAsync(ms);

It never gets past that line and there is no error.

Here is my stripped code:

@page "/uploadtest"
@using Microsoft.EntityFrameworkCore
@using IGPOSCore.Models
@using Microsoft.IdentityModel.Tokens
@using Telerik.Blazor.Components
@using Telerik.Blazor.Components.FileSelect
@using System.ComponentModel
@using Telerik.Windows.Documents.Spreadsheet.FormatProviders
@using Telerik.Windows.Documents.Spreadsheet.FormatProviders.OpenXml.Xlsx
@using Telerik.Windows.Documents.Spreadsheet.Model

<TelerikFileSelect @ref="fileSelect" OnSelect="@OnFileSelected" Multiple=false />
    <TelerikButton OnClick="@(() => LoadExcelFile())" >
        Upload
    </TelerikButton>

@code {
    private TelerikFileSelect? fileSelect { get; set; }
    private FileSelectFileInfo? selectedFile { get; set; }
    private Workbook? workbook { get; set; }

    private async Task OnFileSelected(FileSelectEventArgs args)
    {
        if (args.Files != null && args.Files.Any())
        {
            selectedFile = args.Files.First();
        }
    }

    public async Task LoadExcelFile()
    {
        Guid submissionId = Guid.NewGuid();

        if (selectedFile != null)
        {
            Console.WriteLine($"Processing file: {selectedFile.Name} - {selectedFile.Size} bytes");

            IWorkbookFormatProvider formatProvider = new XlsxFormatProvider();
            @* var ms = new MemoryStream();
            await selectedFile.Stream.CopyToAsync(ms);
            workbook = formatProvider.Import(ms, TimeSpan.FromSeconds(30)); *@
            workbook = formatProvider.Import(selectedFile.Stream, TimeSpan.FromSeconds(30));
            
        }
    }
}

When using the Data Grid with row virtualization we set a pagesize large enough so with normal usage you almost never see the rows loading when scrolling downwards. However when scrolling upwards rows always need to be loaded. The pagesize only affects the items loaded downwards.

From a user experience this is counterintuitive because the rows are visible when first opening the grid, but after scrolling down and back up the rows now need to be loaded again.

Is there a way to have items preloaded in both directions so we always get a smooth user experience?

Any ideas on how to make the width of the column on the timeline smaller?   

I can make the text smaller by updating this css.

 .k-gantt .k-table-td

However, I cannot figure out the right combination to adjust for column widths on the time line side.
