1.首先复制extJS的文件夹到根目录。
2.引用程序集
3.配置配置文件:
1 <?xml version="1.0"?>
2 <configuration>
3 <!--.0配置Session-->
4 <configSections>
5 <section name="FineUI" type="FineUI.ConfigSection, FineUI" requirePermission="false" />
6 </configSections>
7 <!-- 可用的配置项（这里列的都是默认值）:
8 Language="zh_CN"
9 AjaxTimeout=""
EnableAjax="true"
Theme="Neptune"
FormMessageTarget="Qtip"
FormOffsetRight=""
FormLabelWidth=""
FormLabelSeparator="："
IconBasePath="~/res/icon"
EnableAjaxLoading="true"
AjaxLoadingType="default"
CustomTheme=""
CustomThemeBasePath="~/res/theme"
-->
<FineUI DebugMode="false" />
<system.web>
<pages controlRenderingCompatibilityVersion="4.0" clientIDMode="AutoID">
<controls>
<add assembly="FineUI" namespace="FineUI" tagPrefix="x" />
</controls>
</pages>
<httpModules>
<add name="FineUIScriptModule" type="FineUI.ScriptModule, FineUI" />
</httpModules>
<httpHandlers>
<add verb="GET" path="res.axd" type="FineUI.ResourceHandler, FineUI" validate="false" />
</httpHandlers>
<httpRuntime maxRequestLength="102400 " />
<customErrors mode="Off" />
<compilation debug="true" targetFramework="4.5"/>
</system.web>
<runtime>
<assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
<dependentAssembly>
<assemblyIdentity name="Newtonsoft.Json" publicKeyToken="30ad4fe6b2a6aeed" culture="neutral" />
<bindingRedirect oldVersion="0.0.0.0-6.0.0.0" newVersion="6.0.0.0" />
</dependentAssembly>
</assemblyBinding>
</runtime>
55 </configuration>
4.前端界面代码：
1 <%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Login.aspx.cs" Inherits="_02Code.Login" %>
2
3 <!DOCTYPE html>
4
5 <html xmlns="http://www.w3.org/1999/xhtml">
6 <head runat="server">
7 <meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
8 <title></title>
9 </head>
<body>
<form id="form1" runat="server">
<x:PageManager ID="PagerManager1" runat="server"></x:PageManager>
<x:Window ID="window1" runat="server" Title="登录表单" IsModal="false" EnableClose="false" WindowPosition="GoldenSection" Width="">
<Items>
<x:SimpleForm ID="SimpleForm1" runat="server" ShowBorder="false" BodyPadding="10px" LabelWidth="60px" ShowHeader="false">
<Items>
<x:TextBox ID="txtName" Label="登录名" runat="server" Required="true"></x:TextBox>
<x:TextBox ID="txtPwd" runat="server" Label="密码" TextMode="Password" Required="true"></x:TextBox>
<x:Button Text="登录" ID="btnLogin" runat="server" Type="Submit" ValidateForms="SimpleForm1" ValidateTarget="Top" OnClick="btnLogin_Click"></x:Button>
</Items>
</x:SimpleForm>
</Items>
</x:Window>
</form>
</body>
</html>
就这么简单。第一个界面搭建完了。
小结：
1)Alert的提示
2)window窗体控件,和他的属性WindowPosition="GoldenSection"
3)控件ext:SimpleForm，简单表单，和button配合用。
4. 表单回发不是整个页面的回发，而是AJAX（这也是ExtAspNet所特有的原生AJAX，无需任何配置和特殊的代码就默认拥有AJAX特性）
