Type

The Type for the control to be created.

Examples

This example overrides the OnAppendToParentBuilder method to check the ControlType property to determine what type of control this builder is applied to. If it is a CustomTextBox, the builder checks whether the value of the HasAspCode property is included in the control. If so, an exception is thrown, if not the HasBody method is called.

C#

using System;
using System.Web.UI;
using System.Web;
using System.Security.Permissions;

namespace ASPNET.Samples
{
    [
    AspNetHostingPermission(SecurityAction.Demand,
        Level=AspNetHostingPermissionLevel.Minimal)
    ]
    public class AppendControlBuilder : ControlBuilder
    {
        // Override the OnAppendToParentBuilder method.
        public override void OnAppendToParentBuilder(ControlBuilder parentBuilder)
        {
            // Check whether the type of the control this builder
            // is applied to is CustomTextBox. If so, check whether
            // ASP code blocks exist in the control. If so, call
            // throw an Exception, if not, call the HasBody method.        
            if (ControlType == Type.GetType("CustomTextBox"))
            {
                if (HasAspCode)
                    throw new Exception("This control cannot contain code blocks.");
                else
                    HasBody();
            }
        }
    }
}
