### Examples

```csharp
namespace AsposeCellsExamples
{
    using Aspose.Cells;
    using Aspose.Cells.Rendering;
    using System;

    public class RenderingClassDrawObjectEventHandlerDemo
    {
        public static void Run()
        {
            // Create a new workbook with sample data
            Workbook workbook = new Workbook();
            Worksheet worksheet = workbook.Worksheets[0];
            worksheet.Cells["A1"].PutValue("Sample Text");
            worksheet.Cells["B2"].PutValue(12345);
            worksheet.Shapes.AddRectangle(5, 5, 50, 100, 200, 300); // Added missing parameter

            // Create PDF save options with custom render handler
            PdfSaveOptions saveOptions = new PdfSaveOptions();
            saveOptions.DrawObjectEventHandler = new CustomDrawObjectHandler();

            // Save workbook to PDF with rendering customization
            workbook.Save("DrawObjectEventHandlerDemo.pdf", saveOptions);
        }
    }

    public class CustomDrawObjectHandler : DrawObjectEventHandler
    {
        public override void Draw(DrawObject drawObject, float x, float y, float width, float height)
        {
            // Demonstrate handling different render object types
            switch (drawObject.Type)
            {
                case DrawObjectEnum.Cell:
                    Console.WriteLine($"Rendering cell at ({x}, {y})");
                    break;
                    
                case DrawObjectEnum.Image:
                    Console.WriteLine($"Rendering image at ({x}, {y})");
                    break;
            }
        }
