How to customize the dropdown fill behavior in SfSpreadSheet?

I want to implement the drag-fill behavior myself. Based on the currently selected cell range and content, for other cells involved in this fill operation, I need to calculate and set values according to the content of previously selected cells. How should I implement this?

Hi crosslife,

Based on the information provided, we understand that you wish to customize the dropdown fill series behavior. To achieve this, you need to define a CustomFillSeriesController class that inherits from the FillSeriesController class. Within this class, you must override the FillSeries and CopySeries methods. These methods provide access to the selected ranges, allowing you to implement custom logic tailored to your specific requirements.
Please find the code snippet below for reference.
Code Snippet:
spreadsheet.ActiveGrid.FillSeriesController = new CustomFillSeriesController(spreadsheet.ActiveGrid);
 public class CustomFillSeriesController : FillSeriesController
{
     public SpreadsheetGrid spreadsheetGrid;
     // Constructor that accepts the SpreadsheetGrid parameter and passes it to the base class
     public CustomFillSeriesController(SpreadsheetGrid spreadsheetGrid)
         : base(spreadsheetGrid)
     {
         this.spreadsheetGrid = spreadsheetGrid;
     }

     protected override void FillSeries(GridRangeInfo oldRange, GridRangeInfo newRange)
     {
         // Implement your custom Logic

     }

     protected override void CopyCells(GridRangeInfo oldRange, GridRangeInfo newRange)
     {
         // Implement your custom Logic
     }
}

Additionally, could you provide more details or share an image illustrating your desired fill series behavior? This will help us offer a more precise and prompt solution for your requirements. Thank you for your understanding.
