I cannot find an option of grid.SaveAsExcel() with blazor. 

I can export the grid using the grid toolbar but I want to export it without using the toolbar. I have a button group which has a row of buttons and I want to export the grid within the OnClick() event of the button group button. 

Could you please see if that is possible? Using .net core hosted blazor wasm

Thanks

Hello.

Is there a Timeline control for Blazor similar to this https://docs.telerik.com/devtools/wpf/controls/radtimeline/visual-structure ? If not, is there a plan for such control?

Thank you

Dear Telerik support team.

Today I updated my blazor app from 2.26 to 2.27 and encountered the following display issue for DDLs and numeric textboxes.
I currently use the local css file from the nuget package, but also tried to use the CDN for the latest version. Switching back from 2.27 to 2.26 on the CDN css perspective, makes the DDLs and numeric textboxes appear properly. Please see my screenshots attached.

Thanks in advance for your support.

Kind regards,
Thomas

I'm using a numeric textbox to handle a decimal value with the Format is set to "#,0" (which it needs to be since the client's specification is to have a whitespace as a decimal separator). While the entered value is less than a thousand then the entire value gets selected when tabbing into the component, but once it's large enough to display a group separator tabbing just puts the cursor at the end of the input without selecting the value.

I believe this to be a bug.

Today I submitted ticket Telerik VS 2022 Extensions break IntelliSense/typing in Visual Studio 2022 Version 17.3.4 but it doesn't show on Support Center under 'Your Support Tickets'. The only ticket that shows is from 9 months ago.

BTW, I'm reporting this thicket and previous ticket under UI for Blazor because I didn't see how to report it for the Extensions and for Support Center. Maybe that's another thing you need to look at?

Please add a Search Box for the ListView like the one for the Grid.

The Scheduler supports many colors for items, but without the feature for blinking

Currently, any datepicker or dropdownlist works great in desktop, but when used in mobile, the dropdowns go off the bottom of the screen and don't fit the window correctly.  Could the dropdowns and datepicker type of the controls have a special "mobile mode" for smaller screen sizes to give a more native mobile feel?  Ex, the standard html select is handled much better by each device including wider options for fingers than the Telerik dropdownlist, but I'd like my site to be responsive for any screen size and not have to use two separate controls.

Hello.

I have a scenario where I need to make some nodes in a TreeView checkable and some not.  It would be nice if there was an "IsCheckable" binding that determines whether a node should render a checkbox or not.

Although I've no use for it yet, the same could be done for "IsSelectable".  

Is there some way to do this already, and I'm just not seeing it?  I'd prefer not to use JavaScript interop, or recreate the checkbox functionality through an ItemTemplate.

I know this has been a request since a long time ago, I found it in the jQuery version, and I have found that Syncfusion has found a way to handle this specific possibility.

As I'm quite enjoying the rest of the Telerik suite for Blazor, I'd like for this ability to be added in the Scheduler.

There are several ways to handle this, but one of the possible ways is what Syncfusion has done with SetWorkHoursAsync(List<DateTime>, String, String, Nullable<Int32>).

I'm usually showing either a specific day or a week, since my locations are possibly open every day of the week.

I'm currently handling breaks/no possible appointment windows during the work period with an uninteractable appointment, so at least I found a way through that.

Telerik Blazor charts are fine for some use cases but D3.js is much more powerful visualization library, could you provide blazor components/interops easily use D3.js in blazor?

The https://nuget.telerik.com/nuget/ is erroring when trying to restore the packages, it's currently breaking our main pipeline.

Could you help with this?

It would be great if we can have bindable readonly time slots, Where are optionally no appointments are possible. 
This is useful for breaks (no appointments at lunch time) or holidays.

I am getting a combination of these two errors below when instituting SignalR

As an extension to a context menu a radial menu control would be a nice addition.

Hi, i have a blazor razor page that has several telerik elements - mainly grids, textboxes etc

 

i am wondering if there is such as feature where i can print the said page as a PDF?

I have found an issue with editing currency values.

Steps to reproduce:

1. Fill up a value 56.55

2. Try to click between 55

3. Cursor is at the end

 

The same issue about clicking between 56, the cursor will be before the dot.

I have a TelerikForm that contains form items within a TabStrip. If one of the items validates as an error it will display the error message and style the form item in red etc .... But if i switch to another tab and come back, the item will lose some of the styling. I have attached a couple screen shots and a sample project to reproduce it.
