Auto-Filter Table with Slicer

In GcExcel, you can automatically filter tables with slicers via using the methods and properties of the ISlicerCaches interface. This helps in creating a new slicer cache for your table.

In order to auto-filter table with slicer, refer to the following example code.

// Defining source data
object[,] sourceData = new object[,]{
   {"Order ID", "Product", "Category", "Amount", "Date", "Country"},
    {1, "Carrots", "Vegetables", 4270, new DateTime(2018, 1, 6),"United States"},
    {2, "Broccoli", "Vegetables", 8239, new DateTime(2018, 1, 7),"United Kingdom"},
    {3, "Banana", "Fruit", 617, new DateTime(2018, 1, 8),"United States"},
    {4, "Banana", "Fruit", 8384, new DateTime(2018, 1, 10),"Canada"},
    {5, "Beans", "Vegetables", 2626, new DateTime(2018, 1, 10),"Germany"},
    {6, "Orange", "Fruit", 3610, new DateTime(2018, 1, 11),"United States"},
    {7, "Broccoli", "Vegetables", 9062, new DateTime(2018, 1, 11),"Australia"},
    {8, "Banana", "Fruit", 6906, new DateTime(2018, 1, 16),"New Zealand"},
    {9, "Apple", "Fruit", 2417, new DateTime(2018, 1, 16),"France"},
    {10, "Apple", "Fruit", 7431, new DateTime(2018, 1, 16),"Canada"},
    {11, "Banana", "Fruit", 8250, new DateTime(2018, 1, 16),"Germany"},
    {12, "Broccoli", "Vegetables", 7012, new DateTime(2018, 1, 18),"United States"},
    {13, "Carrots", "Vegetables", 1903, new DateTime(2018, 1, 20),"Germany"},
    {14, "Broccoli", "Vegetables", 2824, new DateTime(2018, 1, 22),"Canada"},
    {15, "Apple", "Fruit", 6946, new DateTime(2018, 1, 24),"France"},
};

// Initialize the workbook and fetch the default worksheet
var workbook = new Workbook();
IWorksheet worksheet = workbook.Worksheets[0];

// Adding data to the table
worksheet.Range["A:F"].ColumnWidth = 15;
worksheet.Range["A1:F16"].Value = sourceData;
ITable table = worksheet.Tables.Add(worksheet.Range["A1:F16"], true);
table.Columns[3].DataBodyRange.NumberFormat = "$#,##0.00";

// Create slicer cache for table.
ISlicerCache cache = workbook.SlicerCaches.Add(table, "Category", "categoryCache");

// Add slicer for table
ISlicer slicer1 = cache.Slicers.Add(workbook.Worksheets["Sheet1"], "cate1","Category", 20, 550, 100, 200);

// Apply table filter
// This synchronizes automatically to the slicer. The slicer1's selected item is "Fruit".
worksheet.Range["A1:F16"].AutoFilter(2, "Fruit");
