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

When SelectOnFocus="true"
is enabled on the NumericTextBox control, and a format (e.g., Format="N1"
) is set, the SelectOnFocus
functionality does not select all text if the decimal value has no trailing digits. For instance, with the value 76
, the text is not selected on focus, but with the value 76.1
, the text is selected correctly.
<TelerikNumericTextBox @bind-Value="@DecimalValue" Format="N1" SelectOnFocus="true"/>
@code {
private decimal DecimalValue = 76;
}
Steps to Reproduce:
SelectOnFocus="true"
.Format="N1"
.76
(with no trailing digits after the decimal point).Expected Behavior:
The entire text (in this case, 76.0
) should be selected when the NumericTextBox gains focus.
Actual Behavior:
The text is not selected when the NumericTextBox gains focus if the value has no trailing digits after the decimal point (e.g., 76
). However, if the value includes trailing digits (e.g., 76.1
), the text is selected as expected.
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)

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:
I would like the DropDownList to automatically detect the boundaries of the screen in order not to truncate items when the popup is opened.

The request is also valid for the rest of the popups including AutoComplete, ComboBox, Context Menu, MultiSelect.
This is also valid for the Window.
See below repl
https://blazorrepl.telerik.com/GeYodYvp135zJH7N22
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.
Please consider adding to Blazor UI a drop-down treeview component with:
Example:
Thank you
On the NumericTextBox example here
If you put the NumericTextBox in edit mode and hold the up or down key on the keyboard, the value auto increments/decrements.
1/ Can you please replicate this when the mouse is held down when clicking the up down spinner buttons? Users don't want to always use keyboard for this function.
2/ Can you add an acceleration property, eg when mouse/key is held down it increments at rate n1 for first few seconds, then after time s1 it will increment at rate n2 for remaining time mouse/key held?
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
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
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.
When filtering or editing a Grid with enum data, the Name property of their Display parameter is respected.
However, in the initial view mode of the Grid the Name property is not applied and the enum values are rendered regardless of whether or not their Display parameter has a Name property defined.
==========
ADMIN EDIT
==========
In the meantime, a workaround you might try is to create a custom method to check whether Display attribute is defined and get and display its Name property, otherwise display the Enum's member name.
You can then use a Template for the column that uses enum data, cast its context to the model you are using and invoke the method on the field containing the enum. The sample below demonstrates how you can achieve this.
@using System.ComponentModel.DataAnnotations
@using System.Reflection
<TelerikGrid Data=@MyData EditMode="@GridEditMode.Inline" Pageable="true" Height="500px"
OnUpdate="@UpdateHandler" FilterMode="@GridFilterMode.FilterRow">
<GridColumns>
<GridColumn Field=@nameof(SampleData.ID) Editable="false" Title="ID" />
<GridColumn Field=@nameof(SampleData.Name) Title="Name" />
<GridColumn Field=@nameof(SampleData.Role) Title="Position">
<Template>
@{
var currentEmployee = context as SampleData;
var currentRole = GetDisplayName(currentEmployee.Role);
}
@currentRole
</Template>
</GridColumn>
<GridCommandColumn>
<GridCommandButton Command="Save" Icon="save" ShowInEdit="true">Update</GridCommandButton>
<GridCommandButton Command="Edit" Icon="edit">Edit</GridCommandButton>
</GridCommandColumn>
</GridColumns>
</TelerikGrid>
@code {
//custom method to check whether Display attribute is defined and get and display its Name property, otherwise display the Enum's member name
public string GetDisplayName(Enum val)
{
return val.GetType()
.GetMember(val.ToString())
.FirstOrDefault()
?.GetCustomAttribute<DisplayAttribute>(false)
?.Name
?? val.ToString();
}
public void UpdateHandler(GridCommandEventArgs args)
{
SampleData item = (SampleData)args.Item;
//update the view-model
var index = MyData.FindIndex(i => i.ID == item.ID);
if (index != -1)
{
MyData[index] = item;
}
//perform actual data source operations here
}
//model and dummy data generation
public class SampleData
{
public int ID { get; set; }
public string Name { get; set; }
public Role Role { get; set; }
}
public enum Role
{
[Display(Name = "Manager")]
ManagerRole,
[Display(Name = "Employee")]
EmployeeRole,
[Display(Name = "Contractor")]
ContractorRole
}
public List<SampleData> MyData { get; set; }
protected override void OnInitialized()
{
MyData = new List<SampleData>();
for (int i = 0; i < 50; i++)
{
MyData.Add(new SampleData()
{
ID = i,
Name = "name " + i,
Role = (Role)(i % 3) // just some sample to populate initial values for the enum
});
}
}
}
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
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
We find this in our infrastructure but it can be reproduced even in Telerik docs.
Docs page: https://docs.telerik.com/blazor-ui/components/grid/grouping/overview try to drop all three columns using drag and drop in sequence: Team, Name, On Vacation.
Expected sequence: Team, Name, On Vacation
Expected sequence: Team, On Vacation, Name
All Elements are always added as 1 item. It is an important feature for us, as our customers use it frequently.

TELERIK EDIT:
A possible workaround is to intercept the grouping and reorder the groups:
@using Telerik.DataSource
<p>Group by a third column, so that it should come last in the Group Panel:</p>
<TelerikGrid @ref="@GridRef"
Data="@GridData"
Pageable="true"
Sortable="true"
Groupable="true"
FilterMode="GridFilterMode.FilterRow"
OnStateInit="@( (GridStateEventArgs<Employee> args) => OnGridStateInit(args) )"
OnStateChanged="@( (GridStateEventArgs<Employee> args) => OnGridStateChanged(args) )">
<GridColumns>
<GridColumn Field="@nameof(Employee.Name)" />
<GridColumn Field="@nameof(Employee.Team)" />
<GridColumn Field="@nameof(Employee.Salary)" />
<GridColumn Field="@nameof(Employee.OnVacation)" />
</GridColumns>
</TelerikGrid>
@code {
private TelerikGrid<Employee>? GridRef { get; set; }
private List<Employee> GridData { get; set; } = new();
private void OnGridStateInit(GridStateEventArgs<Employee> args)
{
args.GridState.GroupDescriptors = new List<GroupDescriptor>();
args.GridState.GroupDescriptors.Add(new GroupDescriptor()
{
Member = nameof(Employee.Team),
MemberType = typeof(string)
});
args.GridState.GroupDescriptors.Add(new GroupDescriptor()
{
Member = nameof(Employee.OnVacation),
MemberType = typeof(bool)
});
}
private async Task OnGridStateChanged(GridStateEventArgs<Employee> args)
{
if (args.PropertyName == "GroupDescriptors" && args.GridState.GroupDescriptors.Count > 2 && GridRef != null)
{
var secondGroupDescriptor = args.GridState.GroupDescriptors.ElementAt(1);
args.GridState.GroupDescriptors.Remove(secondGroupDescriptor);
args.GridState.GroupDescriptors.Add(secondGroupDescriptor);
await GridRef.SetStateAsync(args.GridState);
}
}
protected override void OnInitialized()
{
var rnd = new Random();
for (int i = 1; i <= 20; i++)
{
GridData.Add(new Employee()
{
Id = i,
Name = "Name " + i,
Team = "Team " + (i % 4 + 1),
Salary = (decimal)rnd.Next(1000, 3000),
OnVacation = i % 3 == 0
});
}
}
public class Employee
{
public int Id { get; set; }
public string Name { get; set; } = string.Empty;
public string Team { get; set; } = string.Empty;
public decimal Salary { get; set; }
public bool OnVacation { get; set; }
}
}
When is Spreadsheet for Blazor available or can i use Kendo Spreadsheat?
