Definisi

Ruang nama:

System.Web.UI.WebControls

Rakitan:

System.Web.dll

Mendapatkan atau mengatur jenis data nilai yang ditampilkan dalam AutoGeneratedFieldProperties objek.

public:
 property Type ^ Type { Type ^ get(); void set(Type ^ value); };

public Type Type { get; set; }

member this.Type : Type with get, set

Public Property Type As Type

Nilai Properti

Type

Type yang mewakili jenis data nilai yang ditampilkan dalam AutoGeneratedFieldProperties objek. Defaultnya adalah null, yang menunjukkan bahwa properti ini tidak diatur.

Contoh

Contoh kode berikut menunjukkan cara menggunakan Type properti untuk menentukan nilai untuk mengatur DataType properti AutoGeneratedField objek.

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;
        }
    }
}

Keterangan

Type Gunakan properti untuk menentukan jenis data nilai yang ditampilkan dalam AutoGeneratedField objek . Jenis data menentukan jenis kontrol apa yang dirender dalam AutoGeneratedField objek untuk menampilkan nilai. Misalnya, kontrol kotak centang ditampilkan saat jenisnya adalah Boolean.
