+# How to enable PivotTable Show Details in XlsIO?
+
+You can enable the PivotTable "Show Details" (drilldown) behavior by setting the implementation property `EnableDrilldown` to `true`. This causes Excel to open a new sheet with the underlying rows when a user double-clicks a summarized value.
+
+The following code examples show how to enable drilldown in XlsIO.
+
+{% tabs %}
+{% highlight c# tabtitle="C# [Cross-platform]" %}
+using (ExcelEngine excelEngine = new ExcelEngine())
+{
+    // Create application and set default version
+    IApplication application = excelEngine.Excel;
+    application.DefaultVersion = ExcelVersion.Xlsx;
+
+    // Open existing workbook with a PivotTable
+    IWorkbook workbook = application.Workbooks.Open(Path.GetFullPath("Data/InputTemplate.xlsx"));
+    IWorksheet worksheet = workbook.Worksheets[1];
+
+    // Get the first PivotTable
+    IPivotTable pivotTable = worksheet.PivotTables[0];
+
+    // Enable drilldown (Show Details) so double-click opens detail rows
+    (pivotTable as PivotTableImpl).EnableDrilldown = true;
+
+    // Save changes
+    workbook.SaveAs(Path.GetFullPath("Output/Output.xlsx"));
+}
+{% endhighlight %}
+
+{% highlight c# tabtitle="C# [Windows-specific]" %}
+using (ExcelEngine excelEngine = new ExcelEngine())
+{
+    // Windows-specific usage is identical for this feature
+    IApplication application = excelEngine.Excel;
+    application.DefaultVersion = ExcelVersion.Xlsx;
+
+    IWorkbook workbook = application.Workbooks.Open("InputTemplate.xlsx");
+    IWorksheet worksheet = workbook.Worksheets[1];
+    IPivotTable pivotTable = worksheet.PivotTables[0];
+
+    // Enable pivot table drilldown
+    (pivotTable as PivotTableImpl).EnableDrilldown = true;
+
+    workbook.SaveAs("Output.xlsx");
+}
+{% endhighlight %}
+
+{% highlight vb.net tabtitle="VB.NET [Windows-specific]" %}
+Using excelEngine As New ExcelEngine()
+    ' Create application and set default version
+    Dim application As IApplication = excelEngine.Excel
+    application.DefaultVersion = ExcelVersion.Xlsx
+
+    ' Open existing workbook with a PivotTable
+    Dim workbook As IWorkbook = application.Workbooks.Open("InputTemplate.xlsx")
+    Dim worksheet As IWorksheet = workbook.Worksheets(1)
+
+    ' Get the first PivotTable
+    Dim pivotTable As IPivotTable = worksheet.PivotTables(0)
+
+    ' Enable drilldown (Show Details)
+    CType(pivotTable, PivotTableImpl).EnableDrilldown = True
+
+    ' Save changes
+    workbook.SaveAs("Output.xlsx")
+End Using
