Ajax ModelPopu and Progress 示例学习

ModelPopu示例:

1.先创建一个ASP.NET WEB项目;

2.为项目中添加一个CSS文件,代码如下所示:

.modalBackground
{
      background-color: blacks;
      filter: alpha(opacity=60);
      opacity: 0.6;
}
.modalPopup
{
      background-color:#ffffdd;
      border-width:3px;
      border-style:solid;
      border-color:black;
      padding:5px;
      width: 350px;
      height:300px;
}

3.把AJAX控件引用到工具箱中去;

4.为默认页面中添加控件,代码如下:

<asp:ScriptManager ID="ScriptManager1" runat="server" />
       Are you sure you want to know the answer?.
       <asp:Button ID="btnYes" runat="server" Text="Yes!" />
       <br />
       <asp:Panel ID="pnlModal" runat="server" CssClass="modalPopup" Style="display: none;">
           Sed ut perspiciatis unde omnis iste natus error sit voluptatem accusantium doloremque
           laudantium, totam rem aperiam, eaque ipsa quae ab illo inventore veritatis et quasi
           architecto beatae vitae dicta sunt explicabo. Nemo enim ipsam voluptatem quia voluptas
           sit aspernatur aut odit aut fugit, sed quia consequuntur magni dolores eos qui ratione
           voluptatem sequi nesciunt. Neque porro quisquam est, qui dolorem ipsum quia dolor
           sit amet, consectetur, adipisci velit, sed quia non numquam eius modi tempora incidunt
           ut labore et dolore magnam aliquam quaerat voluptatem. Ut enim ad minima veniam,
           quis nostrum exercitationem ullam corporis suscipit laboriosam, nisi ut aliquid
           ex ea commodi consequatur? Quis autem vel eum iure reprehenderit qui in ea voluptate
           velit esse quam nihil molestiae consequatur, vel illum qui dolorem eum fugiat quo
           voluptas nulla pariatur?
           <br />
           <asp:Button ID="btnClose" runat="server" Text="Close" />
       </asp:Panel>

5.把鼠标放在Panel控件上,会出现智能扩展,代码如下:

<cc1:ModalPopupExtender TargetControlID="btnYes" ID="pnlModal_ModalPopupExtender"
            runat="server" DynamicServicePath="" Enabled="True" BackgroundCssClass="modalBackground"
            PopupControlID="pnlModal" CancelControlID="btnClose" DropShadow="true">
        </cc1:ModalPopupExtender>

参数说明:

TargetControlID:为目标控件,以就是说单击那一个控件后,回出现什么的那一个控件;

PopupControlID:为弹出的控件;

CancelControlID:为取消时的控件;

运行效果如下所示:

示例二   Progress

1.创建一个ASP.NET WEB 项目

2.为默认页面中添加如下代码:

<head id="Head1" runat="server">
    <title></title>
</head>
<body>
    <form id="form1" runat="server">
    <div>
        <asp:ScriptManager ID="ScriptManager1" runat="server">
        </asp:ScriptManager>
        <asp:UpdateProgress ID="updProgress"

   AssociatedUpdatePanelID="UpdatePanel1" runat="server">
            <ProgressTemplate>
                <img alt="progress" src="../Image/progress.gif" />
                Processing...
            </ProgressTemplate>
        </asp:UpdateProgress>
        <asp:UpdatePanel ID="UpdatePanel1" runat="server">
            <ContentTemplate>
                <asp:Label ID="lblText" runat="server" Text=""></asp:Label>
                <br />
                <asp:Button ID="btnInvoke" runat="server" Text="Click" OnClick="btnInvoke_Click" />
            </ContentTemplate>
        </asp:UpdatePanel>
    </div>
    </form>
</body>
</html>
说明:

AssociatedUpdatePanelID:这个是他的合作控件;

2.为BUTTON添加如下事件:

System.Threading.Thread.Sleep(3000);

Response.Redirect("WebForm1.aspx");
