A Gantt Chart is one big thing missing that is always high on my blazor UI wish list.
Kind regards,
Kay

ADMIN EDIT
For the time being, a workaround could be to wrap a JS widget, an example is available in this sample project, see the MyKendoGantt.razor component.

It would be great if the controls supported arbitrary attributes. Similar to how it is done in the native form editing controls in Blazor framework.
ASP.NET Core Blazor forms and validation
"All of the input components, including EditForm, support arbitrary attributes. Any attribute that doesn't match a component parameter is added to the rendered HTML element."
After upgrading from 1.1.1 to 1.2.0 I get following exception on app start when hosted on azure app service, locally it works fine.
I have tried using the "static assets" and "CDN" version for retrieving the .js file, both yield this error.
An error occurred while starting the application.

<input class="form-control" readonly="@(!EditMode)" type="text" @bind="@FormField.TextValue"/>As far as I can tell none of the Telerik input controls support a read only mode. Putting the same attribute on TelerikDropDownList for instance (not surprisingly) results in this:
All controls (such as TelerikGrid, TelerikDropDownList, etc) should have a "Visible" property. This bindeable boolean value controls whether the control is visible on the page or not:
<TelerikGrid Visible="@IsVisible" />
@functions {
protected bool IsVisible
}
This is a much better method than surrounding the entire control's markup in an @if(IsVisible) block, since that causes the control to get removed/added to the dom at runtime. This can cause many issues such as the control's constructors being fired multiple times, the dom getting "jiggled" about unecessarily.
I feel the "Visible" property is a cleaner way to hide controls.
A basic Menu control is one of the most fundamental common controls .... Why was it not included in the first release of UI for Blazor???
How about a basic fundamental Menu control in the UI for Blazor? If not now, when?
At the moment, dropdown and popups (like the DatePicker and DropDownList) render in the place of declaration, and CSS rules from their parent elements affect them heavily (for example, they are hidden behind grid cells when used as custom editors).
The popups should be detached and rendered higher in the DOM if possible, so they don't get confined in their parent like that. This may be applicable for more components as well.
Would be great to have a user XML Editor, with input/output from string/stream and an attached XSD for continuous validation?
I realise this wouldn't be priority, just wondered if it could be put on roadmap at some point.
Many thanks,
David Speak.
When following the Blazor UI code examples for the Grid, the source for index.cshtml contains the following:
@page "/grid/index"
@using Telerik.Blazor.Components.Grid
@using TelerikBlazor.Shared
@inject HttpClient Http
Notice that the using directive for the Shared component doesn't have a . separating Telerik and Blazor. It should read:
@using Telerik.Blazor.Shared
This is a request for a new feature that I haven't seen across all of the Telerik products.
A new control that makes use of the HTML Canvas to allow for inking within web applications.
Can be used for free hand writing (inking) on mobile devices instead of requiring online keyboard in limited real estate scenarios. Can use to implement signature blocks on forms, convert to text, etc.
