Property Value

Type

A Type that represents the data type of the value displayed in an AutoGeneratedFieldProperties object. The default is null, which indicates that this property is not set.

Examples

The following code example demonstrates how to use the Type property to determine the value with which to set the DataType 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;
        }
    }
}

Remarks

Use the Type property to specify the data type of the value displayed in the AutoGeneratedField object. The data type determines what type of control is rendered in an AutoGeneratedField object to display the value. For example, a check box control is displayed when the type is Boolean.
