AutoGeneratedFieldProperties.Type 屬性

定義

命名空間:

System.Web.UI.WebControls

組件:

System.Web.dll

取得或設定在 AutoGeneratedFieldProperties 物件中顯示之值的資料型別。

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

屬性值

Type

Type，代表 AutoGeneratedFieldProperties 物件中顯示之值的資料類型。 預設值為 null，表示這個屬性尚未設定。

範例

下列程式碼範例示範如何使用 Type 屬性來判斷用來設定 DataType 物件的 屬性 AutoGeneratedField 的值。

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

備註

Type使用 屬性來指定 物件中所 AutoGeneratedField 顯示值的資料類型。 資料類型會決定物件中 AutoGeneratedField 呈現的控制項類型，以顯示值。 例如，當類型為 Boolean 時，會顯示覆選框控制項。
