Exception on chart resize in Blazor

[Kristof]

Hi!

I have multiple charts on a page. When resizing the page a exception occures:

Server-side Blazor: Error: There was an exception invoking 'OnChartResize'. 

However this does not really effect behaviour. On every resize charts are redrawn (this might be intended but not the best UX).

Client-side Blazor: Error: System.ArgumentException: There is no tracked object with id '2'.

And some charts (usually the ones outside viewing area) are NOT redrawn.

See attachments for details.

Thanks for the help.

So far it seems thet this happens when I have multiple Column charts on the same page (renderen inside a foreach block).

The code for a single diagam:

@using Syncfusion.Blazor.Charts;

<div style=@($"height: {Height}; width: {Width}")>

    <SfChart Height=@Height [email protected]>

        <ChartPrimaryXAxis ValueType="Syncfusion.Blazor.Charts.ValueType.Category" Visible="false" />

        <ChartPrimaryYAxis LabelFormat=@("{value}%") />

        <ChartSeriesCollection>

            <ChartSeries DataSource=@Data XName="Id" YName="Data" PointColorMapping="Color" [email protected]>

                <ChartMarker><ChartDataLabel Visible="true" [email protected] Name="Label" /></ChartMarker>

            </ChartSeries>

        </ChartSeriesCollection>

    </SfChart>

</div>

Hi Kristof,

We have ensured the reported scenario with attached code snippet in both client and server side. We are unable to reproduce reported console errors in both client and server. We have attached samples for your reference. Please try to replicate an issue in attached samples or provide us issue reproduced sample, so that it will be helpful for us to proceed further. In latest version, we have changed chart event names. We suggest you change OnChartResize to SizeChanged to resolve an issue.
