Dim column As Integer
Dim value As String
 
value = instance.GetFormula(row, column)

public string GetFormula( 
   int row,
   int column
)

Parameters

Example

This example adds data to the first three columns along with formulas to sum the values. The GetFormula method returns the formula from the second column.

Visual Basic
C#

Private Sub Page_Load(ByVal sender As System.Object,ByVal e As System.EventArgs)Handles MyBase.Load

If(Me.IsPostBack)Then Return

FpSpread1.ActiveSheetView.RowCount=10

Dim i As Integer

Next
