Question

我已经制作了一个自HtmlGenericControl继承的自定义Web控件，并添加了一个名为“ ViewRoles”的属性。呈现控件后，也将属性Viewroles作为标记的属性呈现。

这是控件的代码

[
AspNetHostingPermission(SecurityAction.Demand,Level = AspNetHostingPermissionLevel.Minimal),
AspNetHostingPermission(SecurityAction.InheritanceDemand,Level = AspNetHostingPermissionLevel.Minimal), 
DefaultProperty("TagName"), 
ToolboxData("<{0}:HtmlGenericControl runat=\"server\" ID=\"EDKHGC\" TagName=\"\"></{0}:HtmlGenericControl>")
]
public class HtmlGenericControl : System.Web.UI.HtmlControls.HtmlGenericControl, IVisible
{

    /// <summary>
    /// Main constructor
    /// </summary>
    /// <param name="tag">Name of the Tag</param>
    public HtmlGenericControl(string tag)
        : base(tag)
    {

    }


    private string _viewRoles;

    [Bindable(true), Category("Security"), DefaultValue(""), Description("Roles allowed to view the control")]
    public string ViewRoles
    {
        get
        {
            if (string.IsNullOrEmpty(_viewRoles) && ViewState["viewRoles"] != null)
                _viewRoles = ViewState["viewRoles"].ToString();
            return _viewRoles;
        }
        set
        {
            _viewRoles = value;
            ViewState["viewRoles"] = value;
        }
    }

如果我使用实例化页面中的控件

<cc1:HtmlGenericControl tagname="div" ViewRoles="CustomRole" runat="server" id="myid"></cc1:HtmlGenericControl>

控件呈现为

<div id="myid" viewRoles="CustomRole">

我希望在运行时不呈现属性“ ViewRoles”。是否有特定的属性？否则如何避免呈现该属性？

避免在自定义Web控件中将属性呈现为标签
