tips:CheckBoxList验证

junmy — Sat, 24 Mar 2007 00:40:00 GMT

页面上有个CheckBoxList控件,用户必须选一个选项才能提交,现有的asp.net验证控件还不能验证CheckBoxList，怎么办?
1.新建CheckBoxListRequiredFieldValidator类,继承BaseValidator

namespace WebApplication2
{
    public class CheckBoxListRequiredFieldValidator : BaseValidator
    {
        protected override bool ControlPropertiesValid()
        {
            return true;
        }

        protected override bool EvaluateIsValid()
        {
            return EvaluateIsChecked();
        }

        protected bool EvaluateIsChecked()
        {
            CheckBoxList _cbl = ((CheckBoxList)FindControl(ControlToValidate));
            foreach (ListItem li in _cbl.Items)
            {
                if (li.Selected == true)
                {
                    return true;
                }
            }
            return false;
        }

        protected override void OnPreRender(EventArgs e)
        {
            if (EnableClientScript)
            {
                ClientScript();
            }
            base.OnPreRender(e);
        }

        protected void ClientScript()
        {
            Attributes["evaluationfunction"] = "cb_vefify";

            StringBuilder sb_Script = new StringBuilder();
            sb_Script.Append(""javascript\">");
            sb_Script.Append("\r");
            sb_Script.Append("\r");
            sb_Script.Append("function cb_vefify(val) {");
            sb_Script.Append("\r");
            sb_Script.Append("var val = document.all[document.all[\"");
            sb_Script.Append(ID);
            sb_Script.Append("\"].controltovalidate];");
            sb_Script.Append("\r");
            sb_Script.Append("var col = val.all;");
            sb_Script.Append("\r");
            sb_Script.Append("if ( col != null ) {");
            sb_Script.Append("\r");
            sb_Script.Append("for ( i = 0; i < col.length; i++ ) {");
            sb_Script.Append("\r");
            sb_Script.Append("if (col.item(i).tagName == \"INPUT\") {");
            sb_Script.Append("\r");
            sb_Script.Append("if ( col.item(i).checked ) {");
            sb_Script.Append("\r");
            sb_Script.Append("\r");
            sb_Script.Append("return true;");
            sb_Script.Append("\r");
            sb_Script.Append("}");
            sb_Script.Append("\r");
            sb_Script.Append("}");
            sb_Script.Append("\r");
            sb_Script.Append("}");
            sb_Script.Append("\r");
            sb_Script.Append("\r");
            sb_Script.Append("\r");
            sb_Script.Append("return false;");
            sb_Script.Append("\r");
            sb_Script.Append("}");
            sb_Script.Append("\r");
            sb_Script.Append("}");
            sb_Script.Append("\r");
            sb_Script.Append("");

            Page.ClientScript.RegisterClientScriptBlock(GetType(), "RBLScript", sb_Script.ToString(), false);
        }
    }
}

2.编译生成dll
页面使用

<%@ Register TagPrefix="myCheckBoxList" Namespace="WebApplication2" Assembly="WebApplication2" %>

       <asp:CheckBoxList ID="chkTest" runat="server" Width="132px">
            <asp:ListItem>1asp:ListItem>
            <asp:ListItem>2asp:ListItem>
            <asp:ListItem>3asp:ListItem>
            <asp:ListItem>4asp:ListItem>
            <asp:ListItem>5asp:ListItem>
            <asp:ListItem>6asp:ListItem>
            <asp:ListItem>7asp:ListItem>
        asp:CheckBoxList>

            <myCheckBoxList:CheckBoxListRequiredFieldValidator ID="valMessage"
             ControlToValidate="chkTest" RUNAT="SERVER"
             EnableClientScript="true" ErrorMessage="你必须选择一个选项">
               *
       myCheckBoxList:CheckBoxListRequiredFieldValidator>

tips:asp.net Password控件

junmy — Fri, 23 Mar 2007 15:23:00 GMT

在asp.net中,使用密码控件只需要将TextBox TextMode属性设置为 "Password"即可. 既然asp.net中已经提供现有控件,为何还要重复造轮子？

首先: asp.net默认密码控件当页面回发的时候不能保存刚刚所填的值.

第2 : 也不能为密码框赋值像这样(TxtPassword.Text="junmy")

为了解决这2个问题,这个轮子还是值得发明的 :)

1.新建MyPasswordTextBox 继承 TextBox

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Text;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;

namespace WebApplication2
{
     public class MyPasswordTextBox : TextBox
    {
         public MyPasswordTextBox()
        {
            TextMode = TextBoxMode.Password;
        }
     protected override void OnInit(EventArgs e)
        {
             base .OnInit(e);
             if ( this .Page.IsPostBack)
            {
                 this .Attributes.Add( " value " , this .Page.Request.Form[ this .UniqueID]);
            }
        }
         // 覆盖Text属性
        public override string Text
        {
             get
            {
                 return base .Text;
            }
             set
            {
                 base .Text = value;

                Attributes.Add( " value " , value);
            }
        }
    }
}

2.编译此类生成dll

asp.net页面上如何使用他?

3.添加dll引用.页面注册:

<%@ Register TagPrefix="pw" Namespace="WebApplication2" Assembly="WebApplication2" %>

4.使用
<pw:MyPasswordTextBox id="tbPassword"runat="server">

当然也可以在web.config里注册

   <pages>
        <controls>
            <add tagPrefix="pw" assembly="PasswordTextBox" namespace="WebApplication2"/>
        controls>
    pages>

参考:ASP.NET Password TextBox
