Thanks for contacting Syncfusion support.
We suspect that this issue occurs due to not enabled the enableXHRCredentials API to true. Could you please ensure the sample by set this API as true?
Code Example:
@Html.EJ().Pivot().PivotClient("PivotClient1").Url(Url.Content("~/api/RelationalClient")).EnableXHRCredentials(true)
@Html.EJ().ScriptManager() |
Please let us know if the problem exists.
Regards,
Sivamathi.
