## DefaultStyleSettings.BuiltInPreference property

Indicates whether property for number format is preferable when the style defines both built-in number and custom pattern. Default value is false, that means by default custom pattern will be used to format values as long as it is not empty for one style.

```csharp
public bool BuiltInPreference { get; set; }
```

### Remarks

When loading workbook from existing template file, maybe both built-in number and custom pattern are defined for one style. This property determine whether we should use the built-in number or the custom pattern when formatting values with the style.

### Examples

```csharp
using System;
using Aspose.Cells;

namespace AsposeCellsExamples
{
    public class DefaultStyleSettingsPropertyBuiltInPreferenceDemo
    {
        public static void Run()
        {
            // Create a new workbook
            Workbook workbook = new Workbook();

            // Access default style settings
            DefaultStyleSettings defaultStyleSettings = workbook.Settings.DefaultStyleSettings;

            // Demonstrate BuiltInPreference property
            defaultStyleSettings.BuiltInPreference = false;
            defaultStyleSettings.FontName = "Arial";
            defaultStyleSettings.FontSize = 12;

            // Apply to worksheet
            Worksheet worksheet = workbook.Worksheets[0];
            worksheet.Cells["A1"].PutValue("Sample Text");
            
            // Save the workbook
            workbook.Save("BuiltInPreferenceDemo.xlsx");
        }
    }
}
```
