Trace Precedents in Excel Show Predendents in Excel Sheet with code

Precedents:

It is a Excel method which shows relationship between formulas using arrow objects. This method requires a valid formula in a cell or range to show the relationship else excel will prompt warning.

Select the cell that contains the formula for which you want to find precedent cells.
To display a tracer arrow to each cell that directly provides data to the active cell, on the Formulas tab, in the Formula Auditing group, click Trace Precedents .

Look at the formula highlighted in circle above and see the trace points which is indicating current cell refers to three cells and builds a formula. Let’s see how we can show Trace Precedents using code in excel?

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

C# code example:

private void btnTracePrecedents_Click(object sender, RibbonControlEventArgs e)
{
	//Get current selection
	excel.Range oRange = Globals.ThisAddIn.Application.Selection;

	//Get worksheet reference
	excel.Worksheet oWorksheet = Globals.ThisAddIn.Application.ActiveSheet;

	//check if selection has formula because trace precedents works only on formula cells
	if (Globals.ThisAddIn.Application.WorksheetFunction.IsFormula(oRange))
	{
		oRange.ShowPrecedents();
	}
}

VB.Net code example:

Private ShowPrecedents_Click(sender As Object, e As RibbonControlEventArgs) Handles ShowPrecedents.Click

	'Bind Range object from selection
	Dim oRange As excel.Range
	oRange=Globals.ThisAddIn.Application.Selection

	'check if selection has formula because trace precedents works only on formula cells
	if Globals.ThisAddIn.Application.WorksheetFunction.IsFormula(oRange) Then
		oRange.ShowPrecedents()
	End If

End Sub

VBA code example:

Public Sub ShowPrecedents()
    Selection.ShowPrecedents
End Sub
