Hi Richard,
We have checked the reported issue at our end. We found that the issue occurs due to the property used “SpinnerTemplate” in the SfPivotView tag is deprecated now and no longer be used. To achieve the same, we suggest using the “SpinnerTemplate” option under the “PivotViewTemplates” tag. Please find the highlighted code snippet for your reference below.
Code Example:
<SfPivotView TValue="ProductDetails">
<PivotViewTemplates>
<SpinnerTemplate>
<i class='e-spinner'></i>
</SpinnerTemplate>
</PivotViewTemplates>
<PivotViewDataSourceSettings DataSource="@dataSource">
</PivotViewDataSourceSettings>
</SfPivotView>
Meanwhile, we have prepared a sample for your convenience. Kindly check the sample in the below link.
Also, we will update the UG documentation in our upcoming 2021 Volume 1 release.
Please let us know if you need further assistance on this.
Regards,
Saranya Sivan.
