AllowAdd Property (UltraDataSource)

Indicates whether row adding is allowed. Default is true.

Syntax

Visual Basic

'Declaration
 
Public Property AllowAdd As Boolean

C#

public bool AllowAdd {get; set;}

Remarks

Setting AllowAdd to true will prevent the controls bound to this data source from adding rows to it.

Example

Following code sets AllowAdd, AllowDelete and ReadOnly properties on the UltraDataSource as well as UltraDataBand objects.

Visual Basic

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


    Private Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles button1.Click
        ' Following code disables adding rows in all bands except first
        ' child band. UltraDataBand object has AllowAdd property whose
        ' default value is Default, in which case AllowAdd property off 
        ' the UltraDataSource is used. However if AllowAdd off an
        ' UltraDataBand is explicitly set, it overrides the setting off
        ' the UltraDataSource. The same applies to AllowDelete and ReadOnly
        ' properties.
        ' 
        Me.UltraDataSource1.AllowAdd = False
        Me.UltraDataSource1.Band.ChildBands(0).AllowAdd = DefaultableBoolean.True

        Me.UltraDataSource1.AllowDelete = False
        Me.UltraDataSource1.Band.ChildBands(0).AllowDelete = DefaultableBoolean.True

        ' NOTE: Setting ReadOnly to true disables adding and deleting rows 
        ' regardless of the AllowAdd and AllowDelete property settings.
        Me.UltraDataSource1.ReadOnly = False
        Me.UltraDataSource1.Band.ChildBands(0).ReadOnly = DefaultableBoolean.False
    End Sub
