Examples
The following code example demonstrates how to use the IsReadOnly property to determine the value with which to set the ReadOnly property of an AutoGeneratedField object.
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Text;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Security.Permissions;
using System.Web;
namespace Samples.AspNet.CS.Controls
{
[AspNetHostingPermission(SecurityAction.Demand, Level=AspNetHostingPermissionLevel.Minimal)]
[AspNetHostingPermission(SecurityAction.InheritanceDemand, Level=AspNetHostingPermissionLevel.Minimal)]
public class SimpleCustomControl : DetailsView
{
protected override AutoGeneratedField CreateAutoGeneratedRow(AutoGeneratedFieldProperties fieldProperties)
{
// Create an AutoGeneratedField object.
AutoGeneratedField field = new AutoGeneratedField(fieldProperties.DataField);
// Set the properties of the AutoGeneratedField using
// the values from the AutoGeneratedFieldProperties
// object contained in the fieldProperties parameter.
((IStateManager)field).TrackViewState();
field.HeaderText = fieldProperties.Name;
field.SortExpression = fieldProperties.Name;
field.ReadOnly = fieldProperties.IsReadOnly;
field.DataType = fieldProperties.Type;
return field;
}
}
}

Protected Overrides Function CreateAutoGeneratedRow(ByVal fieldProperties As AutoGeneratedFieldProperties) As AutoGeneratedField
' Create an AutoGeneratedField object.
Dim field As New AutoGeneratedField(fieldProperties.DataField)
' Set the properties of the AutoGeneratedField using
' the values from the AutoGeneratedFieldProperties
' object contained in the fieldProperties parameter.
CType(field, IStateManager).TrackViewState()
field.HeaderText = fieldProperties.Name
field.SortExpression = fieldProperties.Name
field.ReadOnly = fieldProperties.IsReadOnly
field.DataType = fieldProperties.Type
Return field
End Function
End Class
End Namespace
Remarks
Use the IsReadOnly property to specify whether the values of the field bound to an AutoGeneratedField object can be modified in edit mode. When a data-bound control is in edit mode, fields that are read-only are displayed as plain text, without any editing controls.
