Could not find 'setTheme' ('setTheme' was undefined).

Hi Thaban,

Greetings from Syncfusion.

We set the theme for the chart by using the Theme property in the chart. We have created a simple blazor application using the Chart and the dropdown. Based on the dropdown value, we can set the theme for the Chart. Please find the below sample link for your reference.

Code Snippet:

<SfChart Title="Crude Steel Production Annual Growth" Theme="@theme"></SfChart>
