I just spent hours trying to understand why my grid did not work and threw a "source can't be null" exception at me when I set data to a 100% initialized - not null - list of a struct type.. Eventually I figured that the struct was the problem and turning it into a class fixed it, but that was just by chance.

Please for the sake of developer sanity give this a proper check.

We would like to see all the Blazor controls support the ability to show the time in the browser's local time as a feature that can be enabled.  It should support converted from both UTC and server time.

A question on how to do this has been asked at least twice on the forums:

• https://www.telerik.com/forums/using-client-side-time-zone-for-time-columns-in-blazor-server-grid
• https://www.telerik.com/forums/utc-datetimes-as-local-datetimes-and-vice-versa

Some examples of how other's have implemented this as a control can be founde here:

• https://github.com/dustout/BlazorTime

Hi,

starting with version 6.0, dialogs used together with loading indicator are at wrong z-index order.

- None of hotfixes with "delay" helped.

- users are stucked and cant confirm anything

How to replicate

Click on "Show Confirm with loading indicator". Loading animation should be at BACK of confirm dialog(as at older versions, prior 6.0)

Please consider adding to Blazor UI a drop-down treeview component with:

• multiple selections via checkboxes
• expand/collapse
• lazy loading on expand
• tag mode

Example:

Thank you

Hi,

Here is my demo DatePicker Demo

In Firefox, after I use the mouse to black all texts out, then DatePicker only selects the month field in the place holder. I expect to select all texts.

In Chrome or Edge, the DatePicker works as expected, after blacking texts out, it selects all texts in the place holder

Could you please check the issue?

Thanks and regards,

Tung

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);

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

See below repl

The first dropdown is populated correctly, it is not in a FormItem or Template

The second one, populated in the same way but inside a FormItem context does not show the data, it only redraws and shows data when entering another control i.e. the other working dropdown.

This was previously working when the application was using .net 6 and Telerik 3.6.1
It has since been updated to .net 8 and Telerik 5.1.1

What is the correct way to populate this?
Can you provide more information?

Thanks.

Hi,

We use compact sized grid all the time in our application.

However, with sorting and filtering enabled, the icons take too much space in the header cell and make the actual header text hard to read.

Please consider scale down those icons and reduce padding.

Thanks and best regards,

Peili

Demo: https://blazorrepl.telerik.com/mSOIQZvO51cwrorJ49

===ADMIN EDIT===

To reduce the size of the icons and the font in a Compact Grid, you can follow the approach from the knowledge base article How to make Compact Grid elements smaller.

On Blazor Filter, please consider option to drag and drop rules to re-order the rules. It's a common user request that when creating complex rules that user has ability to move rules around without having to delete and create again. User loses information and data when rules are deleted and can be difficult to relocate in long drop downs.

Ability to drag and drop move of existing rules would improve user experience. Any change to GUI should also reflect in updated FilterDescriptor.

===

ADMIN EDIT

===

The order of the filter rules in one group does not make a difference for the FilterDescriptor. Thus, the current request applies to dragging filter rules from one group to another.

On Blazor filter field parameters, please consider adding

1/ Group options, eg using demo sample fields drop down looks like this

Id
Quantity
Freight
Country
Ship to
Ship Address

but it would be useful to allow groping fields by common categories?

Group-1
-Id
-Quantity
-Freight
Group-2
-Country
-Ship to
-Ship Address

2/ Related, can you also add sort index for group and fields so they can be sorted by index rather than field name. Sometimes groups and fields require different order that is not always alphanumerical and may change order based on other selections.

3/ Maybe consider feature parity with filter field options here querybuilder

Horizontal scrolling in the grid works when its width is set to a fixed value (px, rem, etc.). But the h scroll disappear when a percentage is assigned to the width of the grid.

This seems to be a known 'feature' to Telerik:

https://docs.telerik.com/blazor-ui/components/grid/columns/width?_gl=1*78gyue*_ga*MzUzNTU3NTM0LjE2ODU2MTc3Njk.*_ga_9JSNBCSF54*MTcxMjIyMTAxNS44My4xLjE3MTIyMjExMzQuOS4wLjA.*_gcl_au*MTA3OTA1NzUyOS4xNzEwNTE1Njgy&_ga=2.263164300.1038437897.1712221016-353557534.1685617769

A sensible behaviour is to have the horizontal scrolling enabled and at the same time being able to set the grid to percentage width.

Hi,
I have a little problem with changing the LoadGroupsOnDemand value. Depending on the data in my grid, I set this value to true or false. When updating grid data requires changing the LoadGroupsOnDemand value, I can't do it this way:

LoadGroupsOnDemand = true;
GridData = result;
GridRef.SetStateAsync(GridRef.GetState());

This code throws me an exception.
I need to do something like this to make it work:

LoadGroupsOnDemand = true;
GridRef.LoadGroupsOnDemand = LoadGroupsOnDemand;
GridData = result;
GridRef.SetStateAsync(GridRef.GetState());

This is the code that is executed in onclick. After OnRead is executed, the exception is thrown.

Let me know if you need more information.
