ListIndex Property (UltraGridRow)

Returns the index corresponding to this row from the IList that the control is bound to. Return value of -1 indicates that a row has been deleted or doesn't exist anymore.
Syntax
'Declaration
 
Public ReadOnly Property ListIndex As Integer
public int ListIndex {get;}
Example
Following code illustrates how ListObject and ListIndex properties off the UltraGridRow work. ListObject returns the underlying list object. For example, when bound to a DataSet, list objects would be DataRowView objects. ListObject and ListIndex provide a way to access underlying row objects in the bound data source.

Imports Infragistics.Shared
Imports Infragistics.Win
Imports Infragistics.Win.UltraWinGrid
Imports System.Diagnostics

   Private Sub Form1_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles MyBase.Load

		' Use the same data source and data member to access the currency manager in the
		' button's click handler below.
		Me.ultraGrid1.SetDataBinding(Me.DataSet11, "Customers")

   End Sub

   Private Sub Button87_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles button87.Click

       ' Get the currency manager.
       Dim cm As CurrencyManager = CType(Me.BindingContext(Me.DataSet11, "Customers"), CurrencyManager)

       Dim row As UltraGridRow = Me.UltraGrid1.Rows(0)

       Dim listObject1 As Object = row.ListObject
       Dim listObject2 As Object = cm.List(row.ListIndex)

       ' Write out the type names. If we are bound to a data set like in this case, these
       ' objects should be DataRowView objects.
       Debug.WriteLine("listObject1 type = " & listObject1.GetType().Name)
       Debug.WriteLine("listObject2 type = " & listObject2.GetType().Name)

       ' Following should write out true.
       Debug.WriteLine("Are listObject1 and listObject2 the same: " & (listObject1 Is listObject2))

   End Sub
using Infragistics.Shared;
using Infragistics.Win;
using Infragistics.Win.UltraWinGrid;
using System.Diagnostics;

private void Form1_Load(object sender, System.EventArgs e)
{

	// Use the same data source and data member to access the currency manager in the
	// button's click handler below.
	this.ultraGrid1.SetDataBinding( this.dataSet11, "Customers" );

}

private void button87_Click(object sender, System.EventArgs e)
{

	// Get the currency manager.
	CurrencyManager cm = (CurrencyManager)this.BindingContext[this.dataSet11, "Customers"]; 

	UltraGridRow row = this.ultraGrid1.Rows[0];

	object listObject1 = row.ListObject;
	object listObject2 = cm.List[ row.ListIndex ];

	// Write out the type names. If we are bound to a data set like in this case, these
	// objects should be DataRowView objects.
	Debug.WriteLine( "listObject1 type = " + listObject1.GetType( ).Name );
	Debug.WriteLine( "listObject2 type = " + listObject2.GetType( ).Name );

	// Following should write out true.
	Debug.WriteLine( "Are listObject1 and listObject2 the same: " + ( listObject1 == listObject2 ) );

}
