Click the Preview button to load the example. Notice that the 3rd, 4th, and 5th rows are programmatically selected in the OnInitialized() method. Now, if you hold down the Shift key and click on the 6th row, instead of having the 3rd through 6th rows selected, we get the 1st through 6th row selected.

By design, the Shift + Click shortcut starts the selection from the last clicked row. If no click has taken place, the selection always starts from the first row. How to customize this?

I would like a comopnent similar to this one https://demos.telerik.com/kendo-ui/dropdowntree/index

The goal is to be able to show and select hierarchical data, because the multiselect is flat https://demos.telerik.com/blazor-ui/multiselect/overview

Hello,

Please consider a built-in way to add spacing (gaps, margins, etc.) between the segments of a Donut and Pie charts. The <ChartSeries> tag has such parameters, but they are used for other settings or other series types.

Currently, it is possible to achieve the desired appearance with custom CSS, but that requires knowledge about the Chart rendering.

Hi.

I'd like to request the ability to use a TimeSpanPicker component in Blazor.

For example, see https://www.telerik.com/maui-ui/timespanpicker

Thank you.

Currently using Telerik.DataSource.QueryableExtensions.CreateDataSourceResult() results in queryable.Count() + queryable.Skip(...).Take(...). done seperatelly. EF Core specific tests are already present it seems, based on decompiled code, I can see: "if (!sort.Any() && queryable.Provider.IsEntityFrameworkProvider())". 

Request: Add support for other ORM's that are more capable than EF Core. In case of pagination, window-function could be used to save from extra count query. A short sample bellow:

var dbResults = await queryable
	.Select(x => new {
		Item = x,
		TotalCount = Sql.Ext.Count().Over().ToValue()
	})
	.Skip(() => offset)
	.Take(() => limit)
	.ToListAsync();

var count = dbResults.FirstOrDefault()?.TotalCount ?? 0;
var items = dbResults.Select(x => x.Item);

Hi,

We are using the DropDownList component as an inline editor in the grid, for managing a product hierarchy. Previously we were using the DropDownList with grouping enabled, without virtualization, but due to volume of data we now need to use virtualization.
This does not work with grouping at the moment.

At the bottom of this page it is mentioned that 'Virtual scrolling with grouping will be supported in a future version.'.

Any timeline on this feature?

The need to right-click a file to be able to download it is a bit less intuitive.

I would like to be able to download a file by double-clicking it, or, more generic, to be able to add a double click handler so I can decide what to do with it.

I have recently downloaded the latest Telerik.UI for blazor 5.0.1 commercial and I tried converting a dotnet 8 project to a telerik project using the context menu but the wizard says it can't be converted.

On grids with a lot of data there is a delay between when the grid is assigned the data to when the grid shows the data.  During this UI painting period, the NoDataTemplate is displayed for a second or two.

The grid should not show the NoDataTemplate unless the data source is loaded with an empty collection, not just while it is still trying to show the data.

Note: Having a generic message like in the documentation "No Data available / The data is still loading ..." is not satisfying our users. (Blazor Grid - No Data Template - Telerik UI for Blazor) These should really be two different states that can show different messages.

Thanks

Implementation of one or both of these features:

- Screen boundary detection: The list of child items expands to the opposite direction when necessary to prevent screen boundaries from being crossed.

- ExpandDirection: Gets or sets the direction in which child items will open.

There is no AriaDescribedBy parameter on the Upload when it's inside a Form. I'd like to be able to associate some elements to further describe some validation messages/hints, but there is no parameter exposing that.

For reference, the Angular FormField component associates the underlying control and its visible messages by assigning the aria-describedby attribute to the focusable element.

It is a common and desirable feature to be able to select predefined custom date ranges such as Today, Yesterday, Last Week, Last Month, etc.

This could easily be implemented in the current DateRangePicker if additional templates were provided, such a FooterTemplate, or StartTemplate / EndTemplate. That would allow the customer the most flexibility to implement this or other.

Putting these actions into a separate dropdown outside the date range picker is not ideal from the UX perspective.

Hello,

We use extensively the features of Telerik WPF RadMap and are now migrating to Blazor. So we are trying to use TelerikMap to cover our needs.

TelerikMap doesn't support WMS (most important) and vector tile (nice to have) layers.

Implementing them directly is not really important but having some class available for us to override to implement our way could be enough.

In Telerik WPF RadMap, we had TiledProvider and TiledMapSource from which we made our own implementations to cover our needs (WMS with specific parameters mostly), we override the method GetTile and from here we can do whatever we want.

It would be nice to have the same system in Blazor

Thanks

Thomas
