WebUserControl的简单用法，最近的几个项目都反复用到TextBox,CheckBox,RadiobuttonList，所以玩一下webusercontrol,有个投票功能哦。

1、建一个ascx文件，取名为txtBoxRejectChk.ascx(一个TextBox与Check的排他功能)，code如下：

(1.1).ascx

<%@ Control Language="C#" AutoEventWireup="true" CodeFile="txtBoxRejectChk.ascx.cs" Inherits="txtBoxRejectChk" %>
<%@ Register Assembly="System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"
Namespace="System.Web.UI" TagPrefix="asp" %>

<table id="tbbody" runat="server" cellspacing="10">
<tr>
<td>
<asp:TextBox ID="txtBox" runat="server" Width="600" TextMode="MultiLine" AutoPostBack="true" OnTextChanged="txtBox_TextChanged"></asp:TextBox>
</td>
</tr>
<tr>
<td>
<asp:CheckBox ID="chkBox" runat="server" Text="No improvement required" AutoPostBack="true" OnCheckedChanged="chkBox_CheckedChanged"/>
</td>
</tr>
</table>
(1.2).ascx.cs

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

public partial class txtBoxRejectChk : System.Web.UI.UserControl
{
protected void Page_Load(object sender, EventArgs e)
{

    }
    public String Comment
    {

        get
        {
            return txtBox.Text;
        }
        set
        {
            txtBox.Text = value;
        }

}

public string check
{

        get
        {
            return chkBox.Text;
        }
        set
        {
            chkBox.Text = value;
        }

}

public CheckBox chek
{

        get
        {
            return chkBox;
        }
        set
        {
            chkBox = value;
        }

}

    protected void txtBox_TextChanged(object sender, EventArgs e)
    {
        if (txtBox.Text.Length > 0)
        {
            chkBox.Checked = false;
            chkBox.Enabled = false;
        }
        else
        {
            chkBox.Enabled = true;
        }
    }
    protected void chkBox_CheckedChanged(object sender, EventArgs e)
    {
        if (chkBox.Checked == true)
        {
            txtBox.Text = "";
        }
        else
        {
            chkBox.Checked = false;
        }
    }
}

2.投票的0分-10分的功能

(2.1)MitiSelect.ascx

<%@ Control Language="C#" AutoEventWireup="true" CodeFile="MitiSelect.ascx.cs" Inherits="MitiSelect" %>
<table width="800px">
<tr>
<td colspan="4" align="left">
Completed satisfied
</td>
<td colspan="4" align="center">
Acceptable
</td>
<td colspan="4" align="right">
Dissatisfied
</td>
</tr>
<tr>
<td colspan="12">
<asp:RadioButtonList ID="radlist1" runat="server" RepeatDirection="Horizontal"
Width="800px" onselectedindexchanged="radlist1_SelectedIndexChanged">
<asp:ListItem Text="10"></asp:ListItem>
<asp:ListItem Text="9"></asp:ListItem>
<asp:ListItem Text="8"></asp:ListItem>
<asp:ListItem Text="7"></asp:ListItem>
<asp:ListItem Text="6"></asp:ListItem>
<asp:ListItem Text="5"></asp:ListItem>
<asp:ListItem Text="4"></asp:ListItem>
<asp:ListItem Text="3"></asp:ListItem>
<asp:ListItem Text="2"></asp:ListItem>
<asp:ListItem Text="1"></asp:ListItem>
<asp:ListItem Text="0"></asp:ListItem>
<asp:ListItem Text="DK"></asp:ListItem>
</asp:RadioButtonList>
</td>
</tr>
</table>

(2.2)MitiSelect.ascx.cs

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

public partial class MitiSelect : System.Web.UI.UserControl
{
    string strV = "";
    protected void Page_Load(object sender, EventArgs e)
    {

    }
    public RadioButtonList radblist
    {
        get
        {
            return radlist1;
        }

        set
        {
            radlist1 = value;
        }

    }

    public string strValue
    {
        get
        {
            return strV;
        }

        set
        {
            strV = value;
        }

    }
   protected void radlist1_SelectedIndexChanged(object sender, EventArgs e)
   {

strV=GetRadButtonListValue();
}

   private string GetRadButtonListValue()
   {
       string str = "";
       if (radlist1.Items[0].Selected == true)
       {
           str = "10";
       }
       if (radlist1.Items[1].Selected == true)
       {
           str = "9";
       }
       if (radlist1.Items[2].Selected == true)
       {
           str = "8";
       }
       if (radlist1.Items[3].Selected == true)
       {
           str = "7";
       }
       if (radlist1.Items[4].Selected == true)
       {
           str = "6";
       }
       if (radlist1.Items[5].Selected == true)
       {
           str = "5";
       }
       if (radlist1.Items[6].Selected == true)
       {
           str = "4";
       }
       if (radlist1.Items[7].Selected == true)
       {
           str = "3";
       }
       if (radlist1.Items[8].Selected == true)
       {
           str = "2";
       }
       if (radlist1.Items[9].Selected == true)
       {
           str = "1";
       }
       if (radlist1.Items[10].Selected == true)
       {
           str = "0";
       }
       if (radlist1.Items[11].Selected == true)
       {
           str = "99";
       }
       return str;
   }
}

3.引用webusercontrol,取名为UserWebControl.aspx，code如下：

(3.1)UserWebControl.aspx

<%@ Page Language="C#" AutoEventWireup="true" CodeFile="UserWebControl.aspx.cs" Inherits="UserWebControl" %>
<%@ Register src="txtBoxRejectChk.ascx" tagname="WebUserControl_textRejchk" tagprefix="uc1" %>
<%@ Register src="MitiSelect.ascx" tagname="WebUserControl_mutiselect" tagprefix="uc2" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

    <div>
    <div>
    <asp:Label ID="lbl1" runat="server"></asp:Label>
    <asp:Label ID="lbl2" runat="server"></asp:Label>
        <uc1:WebUserControl_textRejchk ID="txtBoxRechk" runat="server" />
        </div>
            <div>
            <uc1:WebUserControl_textRejchk ID="WebUserControl_textRejchk1" runat="server" />
        </div>
        <div>
        <uc2:WebUserControl_mutiselect ID="WebUserControl_mutiselect1" runat="server" />
            <br />
            <asp:Button ID="Button1" runat="server" οnclick="Button1_Click" Text="Submit" />
            <br />
        </div>
    </div>
    </form>
</body>
</html>
(3.2)UserWebControl.aspx.cs

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

public partial class UserWebControl : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {
        lbl1.Text=txtBoxRechk.Comment;
        lbl2.Text = txtBoxRechk.check;
        lbl2.Text = WebUserControl_textRejchk1.check;
        lbl2.Text = WebUserControl_mutiselect1.strValue;
    }
    protected void Button1_Click(object sender, EventArgs e)
    {
        lbl2.Text = WebUserControl_mutiselect1.strValue;

}
}
