Change dymamically the datasource of the charts

[Anthony Benoit]

Hello,

im currently using syncfusion blazor 23.2.4.

I'm trying to change the datasource of my chart using a dropdownList but when im doing it i have this error that is being trigger : 

Collection was modified; enumeration operation may not execute.

How is this possible to do it ?

<SfAccumulationChart @ref="sfChart" Title="@title" Height="95%" Width="95%" EnableSmartLabels="true" >

    <AccumulationChartEvents Loaded="@LoadHandler" ></AccumulationChartEvents>

    <AccumulationChartSeriesCollection>

        <AccumulationChartSeries DataSource="@objectifForSiteProducts" XName="ProductName" YName="WeightQuantity"

                                 Name="Product" InnerRadius="80%">

            <AccumulationDataLabelSettings Visible="true" Name="ProductName" Position="AccumulationLabelPosition.Outside">

                <Template>

                    @{

                        var data = context as AccumulationChartDataPointInfo;

                    }

                    <table>

                        <tr>

                            <td align="center" style="font-weight: bold;font-size: 14px;"> @Math.Round((double)data.Y, 2) </td>

                        </tr>

                        <tr>

                            <td align="center" style="font-size: 14px; font-weight: bold;"> @Math.Round(data.Percentage, 0) %</td>

                        </tr>

                    </table>

                </Template>

            </AccumulationDataLabelSettings>

        </AccumulationChartSeries>

    </AccumulationChartSeriesCollection>

    <AccumulationChartLegendSettings Visible="true" Position="Syncfusion.Blazor.Charts.LegendPosition.Bottom"></AccumulationChartLegendSettings>

</SfAccumulationChart>
