Visual Basic

'宣言
 
Public Property ReadOnly As Infragistics.Win.DefaultableBoolean

C#

public Infragistics.Win.DefaultableBoolean ReadOnly {get; set;}

解説

ReadOnly をTrueに設定すると、AllowAdd プロパティおよび AllowDelete プロパティの設定にかかわらず、セル値の変更も行の追加と削除も行えません。このプロパティを True に設定すると、UltraDataSource の IBindingList.ReadOnly 実装は True を返します。

使用例

Visual Basic

Imports Infragistics.Shared
Imports Infragistics.Win
Imports Infragistics.Win.UltraWinDataSource


    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        ' Setting ReadOnly to true on the UltraDataSource will prevent adding/deleting
        ' of rows as well as cell content modifications across all bands and columns.
        Me.ultraDataSource1.ReadOnly = True

        ' You can override that setting on an indivudal band.
        Me.ultraDataSource1.Band.ReadOnly = DefaultableBoolean.False

        ' You can also override that setting on an individual column.
        Me.ultraDataSource1.Band.Columns(0).ReadOnly = DefaultableBoolean.True
    End Sub

C#

using Infragistics.Shared;

			// You can override that setting on an indivudal band.
			this.ultraDataSource1.Band.ReadOnly = DefaultableBoolean.False;

			// You can also override that setting on an individual column.
			this.ultraDataSource1.Band.Columns[0].ReadOnly = DefaultableBoolean.True;
