Property Value

Type	Description
String	The name of a JavaScript function used to handle the PreviewClick event.

Remarks

Each time an error occurs on the server, the OnServerError event is raised on the client side. Handle this event to perform actions when a Fetch request completes with an error.

The following code shows an alert box when an internal server error occurs:

reporting_DesignerCustomization.js

window.ReportingDesignerCustomization = {
    onError: function(s, e) {
      alert("An internal server error has occurred.");
    }
}

_Host.cshtml

<script src="~/js/reporting_DesignerCustomization.js"></script>

Designer.razor

<DxReportDesigner ReportName="SampleReport" Height="1000px" Width="100%">
    <DxReportDesignerCallbacks OnServerError="ReportingDesignerCustomization.onError" />
</DxReportDesigner>
