ReadOnly Property (UltraDataBand)

Indicates whether any modifications to data, including adding and deleting of rows, are allowed in row collections associated with this band.

Syntax

Visual Basic

'Declaration
 
Public Property ReadOnly As Infragistics.Win.DefaultableBoolean

C#

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

Remarks

Setting ReadOnly to true will prevent the user from modifying cell values as well as from adding and removing of rows regardless of AllowAdd and AllowDelete property settings. This property caues the IBindingList.ReadOnly implementation in UltraDataSource to return true.

Example

Following code sets ReadOnly property on UltraDataSource, UltraDataBand and UltraDataColumn objects.

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;
using Infragistics.Win;
using Infragistics.Win.UltraWinDataSource;
using System.Diagnostics;


		private void button1_Click(object sender, System.EventArgs e)
		{
			// Setting ReadOnly to true on the UltraDataSource will prevent adding/deleting
			// of rows as well as cell content modifications across all bands and columns.
			this.ultraDataSource1.ReadOnly = true;

			// 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;
		}
