ActiveCell Property

Gets/sets the UltraTreeNodeCell which has the input focus.
Public Property ActiveCell As UltraTreeNodeCell
public UltraTreeNodeCell ActiveCell {get; set;}

As with the ActiveNode property, there can be only one ActiveCell at any given time. The ActiveCell displays a focus rectangle in the user interface to indicate that navigational keyboard actions are performed as relative to that cell.

Note: The ActiveCell by definition must belong to the ActiveNode; setting the ActiveCell property will cause the value of the ActiveNode to change if the new cell belongs to a different node than that referenced by the ActiveNode property.

Note: The UltraTreeNode.ActivateCell method can be used to activate a cell without causing the creation of an UltraTreeNodeCell object.

The following code sample demonstrates how to obtain the value of the ActiveCell:

Imports System.Diagnostics
Imports Infragistics.Win
Imports Infragistics.Win.UltraWinTree

    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

        If Not Me.ultraTree1.ActiveCell Is Nothing Then
            Dim cellValue As Object
            cellValue = Me.ultraTree1.ActiveCell.Value
            If Not cellValue Is Nothing Then
                Debug.WriteLine(String.Format("ActiveCell.Value = {0}", cellValue.ToString()))
                Debug.WriteLine("ActiveCell.Value is null.")
            End If
            Debug.WriteLine("ActiveCell.Value is null.")
        End If

    End Sub
using Infragistics.Win;
using Infragistics.Win.UltraWinTree;
using System.Diagnostics;

		private void button1_Click(object sender, System.EventArgs e)
			if ( this.ultraTree1.ActiveCell != null )
				object cellValue = this.ultraTree1.ActiveCell.Value;

				if ( cellValue != null )
					Debug.WriteLine( string.Format( "ActiveCell.Value = {0}", cellValue.ToString() ) );
					Debug.WriteLine( "ActiveCell.Value is null." );					

				Debug.WriteLine( "ActiveCell.Value is null." );
