Hello.
Is there a Timeline control for Blazor similar to this https://docs.telerik.com/devtools/wpf/controls/radtimeline/visual-structure ? If not, is there a plan for such control?
Thank you
Here is the scenario I would like to implement:
User has a default dashboard, with Customise functionality which would:
- Allow the user to move and resize items (same as now)
- Add / remove item, adding using a drag and drop function from a set of tile types, for example exposed in a TelerikList component. Removing an item with a "delete" button or similar.
- Customise tiles, for example a time period on a chart.
- Save the state of the dashboard.
For loading and saving the dashboard with each tile having a specific content the easiest way I can see would be to bind the TelerikTileLayout to a data source:
<TelerikTileLayout Data="@TileData">
<TileConfiguration></TileConfiguration>
</TelerikTileLayout>
The data would be updated as and when the user configures their dashboard.
For dragging and dropping new tiles a set of events would be necessary, both on the source tile list, e.g. OnDragBegin and on the tile layout OnDrop.
in blazor ui version 2.24.1 I use this code in program.cs for globalization:
public static async Task Main(string[] args)
{
var builder = WebAssemblyHostBuilder.CreateDefault(args);
builder.RootComponents.Add<App>("#app");
builder.Services.AddTransient(sp => new HttpClient { BaseAddress = new Uri(builder.HostEnvironment.BaseAddress) });
builder.Services.AddTelerikBlazor();
// register a custom localizer for the Telerik components, after registering the Telerik services
builder.Services.AddSingleton(typeof(ITelerikStringLocalizer), typeof(SampleResxLocalizer));
var host = builder.Build();
await SetCultureAsync(host);
await host.RunAsync();
}
private static async Task SetCultureAsync(WebAssemblyHost host)
{
var jsRuntime = host.Services.GetRequiredService<IJSRuntime>();
var cultureName =await jsRuntime.InvokeAsync<string>("blazorCulture.get");
if (cultureName != null)
{
var culture = new CultureInfo("fa-IR");
DateTimeFormatInfo info = culture.DateTimeFormat;
info.AbbreviatedDayNames = new string[] { "ی", "د", "س", "چ", "پ", "ج", "ش" };
info.DayNames = new string[] { "یکشنبه", "دوشنبه", "ﺳﻪشنبه", "چهارشنبه", "پنجشنبه", "جمعه", "شنبه" };
info.AbbreviatedMonthNames = new string[] { "فروردین", "ارديبهشت", "خرداد", "تير", "مرداد", "شهریور", "مهر", "آبان", "آذر", "دی", "بهمن", "اسفند", "" };
info.MonthNames = new string[] { "فروردین", "ارديبهشت", "خرداد", "تير", "مرداد", "شهریور", "مهر", "آبان", "آذر", "دی", "بهمن", "اسفند", "" };
info.AMDesignator = "ق.ظ";
info.PMDesignator = "ب.ظ";
info.ShortDatePattern = "yyyy/MM/dd";
info.FirstDayOfWeek = DayOfWeek.Saturday;
CultureInfo.DefaultThreadCurrentCulture = culture;
CultureInfo.DefaultThreadCurrentUICulture = culture;
}
}
when use TelerikDatePicker , id dosenot work properly. the code of my component in here:
<div class="demo-section k-form k-form-vertical">
<div class="k-form-field">
<label for="travel-date" class="k-label k-form-label">Travel Date</label>
<div class="k-form-field-wrap">
<TelerikDatePicker Min="@Min" Max="@Max" @bind-Value="@selectedDate" Id="travel-date"></TelerikDatePicker>
</div>
</div>
<div class="k-form-field">
<p>The selected travel date is: <strong>@selectedDate?.ToShortDateString()</strong></p>
<p>The selected travel date is: <strong>@selectedDate?.ToString()</strong></p>
<p>The selected travel date is: <strong>@selectedDate?.ToUniversalTime()</strong></p>
<p>The selected travel date is: <strong>@selectedDate?.ToLongDateString()</strong></p>
</div>
</div>
@code {
public DateTime Max = new DateTime(2050, 12, 31);
public DateTime Min = new DateTime(1950, 1, 1);
private DateTime? selectedDate=DateTime.Now;
}
when click the datepicker the date is not correct :
Hi,
When displaying a MultiSelect control on a TelerikWindow (modal), the dropdown of items is displayed behind the dialog:
How can I change the Z-Index of the dropdown?
I want the grid to be able to resize all the columns (or only certain columns) to fit their data, when the data loads, without the user having to double click the border between them.

ADMIN EDIT
Automatic application of the auto fitting will come with a flicker, and that's why it was declined as a feature originally. In Blazor we have a detachment between code and when exactly something is rendered. So, we have no way to trigger the resizing logic immediately after the columns content is rendered. The events that are available will cause a flicker and can cause a performance hit - both for the browser and also by raising StateChanged multiple times.
Another caveat is how would this be exposed for configuration - should it work for all columns at once, or only for certain columns (how to control for which ones), how to control which data-related events should invoke this logic (or should it happen super often on any event). Exposing such configuration is likely to lead to a property hell type of situation.
Perhaps a way to get this would be to provide API on the grid to invoke that functionality that you can call as required by your logic and UX: https://feedback.telerik.com/blazor/1513384-programmatically-invoke-fit-to-width-functionality-for-the-grid-columns.
Nevertheless, we will keep this open to monitor for feedback, what is requested, interest and how people would want it exposed. Leave your comments and preferences here.

See more details in the following KB article: https://docs.telerik.com/blazor-ui/knowledge-base/textbox-validate-on-change and if the behavior and solution there do not fit your needs, leave your comments and ideas on how you want this exposed for configuration and what the desired behavior is. Also, make sure to Vote for this enhancement so we can gauge the public interest in it.
I would like to be able to set the Id on any Blazor component for automated testing purposes.

ADMIN EDIT
If you need something different than automated testing selectors, please add your use case in the comments.
For automated testing, you can cascade selectors through a parent element (e.g., a div or span) that has the desired attributes (be that id, class, some data-* attribute, etc.). Adding ID parameters to Blazor components can easily make them brittle because they can be repeated and included in arbitrary hierarchy easily - that's the core concept of a razor component - so such IDs need to be unique, which defeats the predictability you will need for testing.
If you are interested in testing with Selenium, you may find useful this request: https://feedback.telerik.com/blazor/1513117-translators-for-selenium-testing-for-the-telerik-ui-for-blazor-components. If so, Vote for it and Follow it so we can know there is interest, and so you can get status updates.
