Slicers in Excel Addin create slicers in excel c#

Slicers:

An advanced level of filter which provides better visualization. I would not write much here, If you wish to see how to create Slicers in Excel please refer my previous article Slicers in Excel VBA. Let’s take a look in VSTO C# how you can create slicers. There are couple of things which needs to be taken under consideration before creating slicers in Excel C#.

Slicers can be formed over a Data Table or Pivot Table
Slicers requires Cache like Pivot
Table name should be remember (Please refer below screen shot) which can be obtained from Design Tab under table properties

Prerequisites:

Visual Studio 2015 or above having Microsoft Office for Developer Tool installed
Create Excel Addin in C# code style (Visual Studio Tools for Office)
Create a ribbon designer and put button

Code example to create Slicers:

private void btnSlicer_Click(object sender, RibbonControlEventArgs e)
{
	//Active workbook reference
	excel.Workbook oWorkbook = Globals.ThisAddIn.Application.ActiveWorkbook;
	
	//Active worksheet reference
	excel.Worksheet oWorksheet = oWorkbook.ActiveSheet;
							
	//Retain selection
	excel.Range oSelection = Globals.ThisAddIn.Application.Selection;
	
	//build slicer caches collection
	excel.SlicerCaches oSlicerCaches = oWorkbook.SlicerCaches;

	
	//Creating Address
	excel.SlicerCache oSlicerCacheAddress = oSlicerCaches.Add2(oWorksheet.ListObjects["Table1"], "Address", "mSlicer");
	//Add slicer
	oSlicerCacheAddress.Slicers.Add(oWorksheet, System.Reflection.Missing.Value, "Address", "Address", 156,
		394, 144, 198);
	

	//Creating Address
	excel.SlicerCache oSlicerCacheYearBuildIn = oSlicerCaches.Add2(oWorksheet.ListObjects["Table1"], "YearBuilt", "mSlicer1");
	//Add slicer
	oSlicerCacheYearBuildIn.Slicers.Add(oWorksheet, System.Reflection.Missing.Value, "YearBuilt", "YearBuilt", 200,
		450, 144, 198);
	
}

Code example to delete slicers:

private void btnSlicer_Click(object sender, RibbonControlEventArgs e)
{
	//Active workbook reference
	excel.Workbook oWorkbook = Globals.ThisAddIn.Application.ActiveWorkbook;
	
	//Active worksheet reference
	excel.Worksheet oWorksheet = oWorkbook.ActiveSheet;
							
	//Retain selection
	excel.Range oSelection = Globals.ThisAddIn.Application.Selection;
	
	//build slicer caches collection
	excel.SlicerCaches oSlicerCaches = oWorkbook.SlicerCaches;

	//Delete exisiting slicers
	foreach (excel.SlicerCache osCache in oSlicerCaches)
	{
		foreach (excel.Slicer oCache in osCache.Slicers)
		{
			oCache.Delete();
		}
	}
}
