This is more or less a question and request.
With the new "Lazy Loading" feature of Blazor .Net 5, is it possible that Telerik can use this feature internally, to load only components/library as the app needs it at runtime to save initial load time?
Thanks!
Just wondering if there has been any movement on this issue. We are seeing this in our production system application insights logs. Thanks!

Overview
As a developer user, I need to add a Markdown Editor control to my Blazor UI application so that I can capture and display markdown-compliant text input.
Acceptance criteria
- The editor control supports rich WYSIWYG editing with support for standard markdown styling including: headers, emphasis, lists, images, links, blockquotes and inline code.
- The editor control supports raw markdown editing mode, as well as WYSIWYG (preview) mode.
- The editor control supports raw markdown output and HTML output.
Bonus criteria
- A paired Markdown Display control supports presentation of markdown as HTML (so that developers can store markdown in a database, for example, and convert to HTML on the client for display.
I'd like at least a linear gauge

Grid errors with both filtering and a detail template:
<Telerik.Blazor.Components.TelerikGrid Data="@GridData" FilterMode="Telerik.Blazor.GridFilterMode.FilterRow">
<GridColumns>
<Telerik.Blazor.Components.GridColumn Title="Name" Filterable="true" Field="@nameof(GridItem.Name)"></Telerik.Blazor.Components.GridColumn>
<Telerik.Blazor.Components.GridColumn Field="@nameof(GridItem.Id)" Filterable="true" Title="Id"></Telerik.Blazor.Components.GridColumn>
</GridColumns>
<DetailTemplate>
<div>Custom Template</div>
</DetailTemplate>
</Telerik.Blazor.Components.TelerikGrid>@code {
List<GridItem> GridData { get; set; } = new List<GridItem>();
protected override void OnInitialized()
{
GridData = GenerateData();
}
private List<GridItem> GenerateData()
{
List<GridItem> data = new List<GridItem>();
for (int i = 0; i < 5; i++)
{
GridItem mdl = new GridItem { Id = i, Name = $"Name {i}" };
data.Add(mdl);
}
return data;
}
public class GridItem
{
public int Id { get; set; }
public string Name { get; set; }
}
}The grid renders correctly with either the DetailTemplate or FilterMode, but not both.

Like the grouping in the Kendo combo box https://demos.telerik.com/kendo-ui/combobox/grouping
<AdminEdit>
This Feature Request would be an umbrella for implementing items grouping for select components (ComboBox, DropDownList, MultiSelect, and others).
</AdminEdit>
I would like to have a boolean flag like ExpandDropdownOnFocus which when set to true and the component is focused the dropdown will be expanded.
ADMIN EDIT: When voting, please add your comment on how you would like this to be implemented. At the moment, there are two ideas:
- A parameter that, when set to true, will make the dropdowns shop up when the component receives focus - less code, but solves only one specific scenario
- An OnFocus event plus an instance method that opens the dropdown - a little more code (handle an event, populate a reference, call its method) which will provide more functionality and flexibility as the event will let you know that focus happened and you can add more logic (calculations, change CSS classes,...)
Hi, It is possible to have a component that enables the use of the camera and to be able to scan barcodes or QR (1D & 2D), for Blazor Web assembly and Blazor Server Side. Now this require JavaScript library like as QuaggaJS.
I think that having such a component is very useful and will allow you to build applications with advanced functionalities, other companies offer but only to generate barcodes or QR codes.
Example thanks aLorsSilvermort : https://github.com/LorsSilvermort/BlazorBarcodeReader

Hello,
im trying to render a treview but its not showing any item, im also print the results of my query on a table using a for loop and it shows the results ok , but the trevieww its not loading any data. Attached my code :
@inherits LayoutComponentBase@inject Blazored.LocalStorage.ILocalStorageService oLocalStorage
@using MAPCRUD.Model
@using MAP.Interfaces
@inject IMapTreeviewMenuService MapTreeviewMenuService
<TelerikRootComponent>
<div class="sidebar">
<NavMenu />
@if (MapMenuData == null)
{
<p><em>Loading...</em></p>
}
else
{
<TelerikTreeView Data="@MapMenuData">
<TreeViewBindings>
<TreeViewBinding ParentIdField="@(nameof(MapTreeviewMenu.ParentIdValue))" TextField="@(nameof(MapTreeviewMenu.Text))" UrlField="@(nameof(MapTreeviewMenu.Url))" IconField="@(nameof(MapTreeviewMenu.Icon))" ></TreeViewBinding>
</TreeViewBindings>
</TelerikTreeView>
<table>
<thead>
<tr>
<th>Text</th>
</tr>
</thead>
<tbody>
@foreach (var menuData in MapMenuData)
{
<tr>
<td style="color:#fff;">@menuData.Url</td>
</tr>
}
</tbody>
</table>
}
</div>
<div class="main">
<div class="top-row px-4">
<a href="https://docs.microsoft.com/aspnet/" target="_blank">About</a>
</div>
<div class="content px-4">
@Body
</div>
</div>
</TelerikRootComponent>
@code {
private IEnumerable<MapTreeviewMenu> MapMenuData;
protected override async Task OnInitializedAsync()
{
await oLocalStorage.SetItemAsync("CollegeID", 1);
await oLocalStorage.SetItemAsync("ApplicationID", 1);
await oLocalStorage.SetItemAsync("RoleID", 2);
await oLocalStorage.SetItemAsync("UserID", 1);
int CollegeID = await oLocalStorage.GetItemAsync<int>("CollegeID");
int ApplicationID = await oLocalStorage.GetItemAsync<int>("ApplicationID");
int RoleID = await oLocalStorage.GetItemAsync<int>("RoleID");
int UserID = await oLocalStorage.GetItemAsync<int>("UserID");
MapMenuData = await MapTreeviewMenuService.GetMenuItems(CollegeID, ApplicationID, RoleID, UserID);
}
}
This error appears after update 15, in 14.1 it works correctly.
ADMIN EDIT:
This error occurs from the FilterMode set to FilterRow. As a workaround, until the fix is implemented, you could use the FilterMenu instead.
