Calculate Method

Calculates the specified formula and returns the value.
Syntax
'Declaration
 
Public Function Calculate( _
   ByVal formula As String _
) As Infragistics.Win.CalcEngine.UltraCalcValue
public Infragistics.Win.CalcEngine.UltraCalcValue Calculate( 
   string formula
)

Parameters

formula
Formula to calculate.

Return Value

The result of the formula.
Remarks

The Calculate method allows you to calculate a formula once without creating a NamedReference.

This method does not ensure that any dependants of the specified formula are calculated. When using a CalcFrequency of Asynchronous, you should call the ReCalc method before calling this method.

This method throws an exception if the formula has a syntax error. Any other kind of error is returned as an instance of Infragistics.Win.CalcEngine.UltraCalcValue that represents the error that occurred.

Example
Following code shows you how to calculate a formula on fly.

Imports Infragistics.Shared
Imports Infragistics.Win
Imports Infragistics.Win.UltraWinGrid
Imports Infragistics.Win.CalcEngine
Imports Infragistics.Win.UltraWinCalcManager

    Private Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles button1.Click
        Dim formula As String = "average( 10, 15, 20 )"
        Dim result As UltraCalcValue = Me.UltraCalcManager1.Calculate(formula)
        If result.IsError Then
            MessageBox.Show(Me, result.ToString())
        Else
            Dim doubleVal As Double = result.ToDouble()
            MessageBox.Show(Me, doubleVal.ToString())
        End If
    End Sub
using Infragistics.Shared;
using Infragistics.Win;
using Infragistics.Win.UltraWinGrid;
using System.Diagnostics;
using Infragistics.Win.CalcEngine;
using Infragistics.Win.UltraWinCalcManager;

		private void button1_Click(object sender, System.EventArgs e)
		{
			string formula = "average( 10, 15, 20 )";
			UltraCalcValue result = this.ultraCalcManager1.Calculate( formula );
			if ( result.IsError )
			{
				MessageBox.Show( this, result.ToString( ) );
			}
			else
			{
				double doubleVal = result.ToDouble( );
				MessageBox.Show( this, doubleVal.ToString( ) );
			}
		}
