ReadOnly Property (UltraDataSource)

Indicates whether any modifications to data, including adding and deleting of rows, are allowed in row collections associated with this band.
Syntax
'Declaration
 
Public Property ReadOnly As Boolean
public bool ReadOnly {get; set;}
Remarks

Setting ReadOnly to true makes the data source read-only so that the controls bound to this data source can not make any modifications. Setting it to true will prevent cell content modifications as well as adding and deleting of rows regardless of the AllowAdd and AllowDelete settings. This property caues the IBindingList.ReadOnly implementation in UltraDataSource to return true.

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

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
