CalcSettings Class

Represents a control to the CalcManager component
Syntax
'Declaration
 
Public Class CalcSettings 
   Inherits Infragistics.Shared.SubObjectBase
   Implements Infragistics.Win.CalcEngine.IFormulaProvider 
public class CalcSettings : Infragistics.Shared.SubObjectBase, Infragistics.Win.CalcEngine.IFormulaProvider 
Remarks

The CalcSettings object defines properties that determine how the UltraCalcManager deal with a particular control.

In order for any control to be used in the Calculation Network, a CalcSettings must be created for that control. This can be done by creating a new CalcSettings and adding it to the network via the UltraCalcManager.SetCalcSettings method or by calling UltraCalcManager.GetCalcSettings, which will automatically get the existing CalcSetting for a control or create one if none exists.

Always be certain to set the PropertyName on the CalcSettings, to the UltraCalcManager knows which property of the control to use for calculations.

Example
Following code assigns a formula to textBox1 that multiplies the value of textBox2 by 2.

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

    Private Sub Form1_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles MyBase.Load
        ' Ensure that the form contains an UltraCalcManager and two textboxes, 
        ' one named textBox1 and the other named textBox2.
        Dim calcSettings As CalcSettings = New CalcSettings()
        ' This formula will multiply the value of textBox2 by 2.
        calcSettings.Formula = "2 * [//textBox2]"
        calcSettings.PropertyName = "Text"
        Me.ultraCalcManager1.SetCalcSettings(Me.TextBox1, calcSettings)

        calcSettings = New CalcSettings()
        calcSettings.PropertyName = "Text"
        ' Treat the values of the textBox2 as double. Text property of TextBox is
        ' a string type and since textBox2 is a source of value to a formula, indicate 
        ' to the calc-manager that the value should be treated as a double rather
        ' than as a string. 
        calcSettings.TreatAsType = GetType(Double)
        Me.ultraCalcManager1.SetCalcSettings(Me.TextBox2, calcSettings)
    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 Form1_Load(object sender, System.EventArgs e)
		{
			// Ensure that the form contains an UltraCalcManager and two textboxes, 
			// one named textBox1 and the other named textBox2.
			CalcSettings calcSettings = new CalcSettings( );
			// This formula will multiply the value of textBox2 by 2.
			calcSettings.Formula = "2 * [//textBox2]";
			calcSettings.PropertyName = "Text";
			this.ultraCalcManager1.SetCalcSettings( this.textBox1, calcSettings );

			calcSettings = new CalcSettings( );
			calcSettings.PropertyName = "Text";
			// Treat the values of the textBox2 as double. Text property of TextBox is
			// a string type and since textBox2 is a source of value to a formula, indicate 
			// to the calc-manager that the value should be treated as a double rather
			// than as a string. 
			calcSettings.TreatAsType = typeof( double );
			this.ultraCalcManager1.SetCalcSettings( this.textBox2, calcSettings );
		}
