AutoGeneratedField Constructor

Initializes a new instance of the AutoGeneratedField class with the specified data field.

Namespace:  System.Web.UI.WebControls
Assembly:  System.Web (in System.Web.dll)

public AutoGeneratedField(
	string dataField
)

Parameters

dataField
Type: System.String

The name of the data field to bind to the AutoGeneratedField.

Use this constructor to initialize a new instance of the AutoGeneratedField class. This constructor is generally used by data-bound controls (such as GridView and DetailsView) when creating automatically generated fields.

The following example demonstrates how to use this constructor to create a new instance of the AutoGeneratedField class when implementing a custom control that derives from the DetailsView control.


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;
        }

    }
}
