I am just creating an application with Blazor using Telerik UI for Blazor. It seems that a few properties and methods from former ASP.NET Core version are missing, at least:

  • SeriesDefaults

  • no more "xxx.visual"

  • "OnRender" event

Especially the "visual" function and the "OnRender" event among other low-level API is sorely missed since I have to draw additional things on the charts. Can anyone give me a tip on how to do the same thing with Blazor?

Thanks in advance!

Hello Heiko,

I have added two feature requests to your behavior:

I have added your Vote for both of them and you are automatically subscribed to receive email notifications on status updates.

The Chart Series Visuals are already an existing feature request - Custom rendering for series element - visual template. Your Vote is already in and you can click the Follow button to receive email notifications on status updates.

Hello Svetoslav,

thank you for adding these as feature requests, it is very much appreciated!

Do you know a way to accomplish changes to a chart during or after render? I have to put a line with a small text on a stacked bar at a certain position.

Regards
Heiko

Hello Heiko,

Drawing Horizontal and vertical lines on the Chart is a planned feature request. In the public thread, you can see how to achieve the desired behavior until the official feature is implemented.

I have added your Vote for the request and you can click the Follow button to receive email notifications on status updates.
