Hello,
in the WPF Pivot component I created custom calculated fields. Please expose a similar feature in the Blazor PivotGrid.
var OeeA = new OeeA_BerechnetesFeld(); //Telerik.Pivot.Core.CalculatedField
OeeA.Name = "OEE A";
DataSource.CalculatedFields.Add(OeeA); // DataSource is the LocalDataSourceProvider
DataSource.AggregateDescriptions.Add(new CalculatedAggregateDescription { CalculatedFieldName = "OEE A", StringFormat = "#.#0" });
