Syntax

Visual Basic

'Declaration
 
Public Property ActiveCellAppearance As Infragistics.Win.AppearanceBase

C#

public Infragistics.Win.AppearanceBase ActiveCellAppearance {get; set;}

Remarks

The ActiveCellAppearance property is also exposed by the UltraTreeColumnSettings and UltraTreeColumnSet) classes; setting it at the UltraTreeNodeColumn level will affect only cells displayed by this column.

Example

The following code sample demonstrates how to use the cell editing related properties pf the UltraTreeNodeColumn to customize the cell editing functionality for a particular column:

Visual Basic

Imports Infragistics.Win
Imports Infragistics.Win.UltraWinTree

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

        Dim columnQuantity As UltraTreeNodeColumn = Me.ultraTree1.ColumnSettings.ColumnSets("Order Details").Columns("Quantity")
        Dim columnDiscount As UltraTreeNodeColumn = Me.ultraTree1.ColumnSettings.ColumnSets("Order Details").Columns("Discount")
        Dim columnProduct As UltraTreeNodeColumn = Me.ultraTree1.ColumnSettings.ColumnSets("Order Details").Columns("ProductID")

        '	Set the 'Quantity' column to have a ForeColor of blue for
        '	the active cell, allow editing, and restrict the number of
        '	characters accepted for input so that the end user cannot
        '	enter a value greater than 99. Also, don't allow null values.
        columnQuantity.ActiveCellAppearance.ForeColor = Color.Blue
        columnQuantity.AllowCellEdit = AllowCellEdit.Full
        columnQuantity.MaxLength = 2
        columnQuantity.Nullable = Nullable.Disallow

        '	make the 'Discount' column read-only.
        columnDiscount.AllowCellEdit = AllowCellEdit.ReadOnly

        '	Enable tooltips for the 'Product' column, since the
        '	name of the product might not always be fully visible.
        columnProduct.TipStyleCell = TipStyleCell.Show
    End Sub

C#

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

		private void button3_Click(object sender, System.EventArgs e)
		{
			UltraTreeNodeColumn columnQuantity = this.ultraTree1.ColumnSettings.ColumnSets["Order Details"].Columns["Quantity"];
			UltraTreeNodeColumn columnDiscount = this.ultraTree1.ColumnSettings.ColumnSets["Order Details"].Columns["Discount"];
			UltraTreeNodeColumn columnProduct = this.ultraTree1.ColumnSettings.ColumnSets["Order Details"].Columns["ProductID"];

			//	Set the 'Quantity' column to have a ForeColor of blue for
			//	the active cell, allow editing, and restrict the number of
			//	characters accepted for input so that the end user cannot
			//	enter a value greater than 99. Also, don't allow null values.
			columnQuantity.ActiveCellAppearance.ForeColor = Color.Blue;
			columnQuantity.AllowCellEdit = AllowCellEdit.Full;
			columnQuantity.MaxLength = 2;
			columnQuantity.Nullable = Nullable.Disallow;

			//	make the 'Discount' column read-only.
			columnDiscount.AllowCellEdit = AllowCellEdit.ReadOnly;

			//	Enable tooltips for the 'Product' column, since the
			//	name of the product might not always be fully visible.
			columnProduct.TipStyleCell = TipStyleCell.Show;
		}
