FlowMan工作流平台页面控件——Ext.Net V1.0

FlowMan页面控件——Ext.NET V1.0

试用过FlowMan的客户大多对它简洁美观的界面抱持肯定态度，其实技术人员在开发界面的时候用了一个小工具，今天开始我们将会用四篇连载和技术爱好者分享它的一些使用方法。

 

Ext.NET，这个名字可能有些许陌生，但说起ExtJS和Coolite大家应该是相当熟悉的。其实Ext.NET原名Coolite，是Coolite发展到1.0版本后对该产品的重新命名。Ext.NET是基于.NET Framework 3.5的一套支持ASP.NET AJAX的Web控件，它基于跨浏览器的ExtJS 库开发而来并简化了开发步骤，包含有丰富的Ajax运用。

 

Ext.NET是开源的。由于Ext.NET基于ExtJS的缘故，所以不可避免会有类似ExtJS控件运行又大又慢的毛病，但因为它界面美观，减少了很多美工的精力，你就可以省掉一大串的js代码，界面完全可以用Ext.NET简单配置就得到很炫的页面效果，使程序员可以专注于后台代码的编写。而且Ext.Net的Ajax+Json操作简单方便，因此作为企业应用是相当不错的选择。

ExtJS官方下载：www.extjs.com

Ext.NET最大不足：还是开发阶段，存在不少BUG。

 

Ext.NET配置方法：

 

1.从官方网站下载Ext.NET：(现版本为Coolite 0.8.2，Ext.NET1.0为Beta版尚未开放下载)

http://www.coolite.com/download/

 

2.项目中引用

在项目点击引用，通过浏览增加Ext.NET.dll、Ext.NET.Utilities.dll引用。

 

3.工具箱增加

在工具箱增加Tab Ext.NET。增加文件:Ext.NET.dll。

 

4.修改Web.config文件，如下设置

<?xml version="1.0"?><configuration>

    <configSections>

</configuration>

 

5.在页面中添加Ext.NET引用

<%@ Register Assembly="Ext.Net" Namespace="Ext.Net" TagPrefix="ext" %>

 

6.在使用Ext.NET控件时必须注意，添加任意控件之前必须添加ResourceManager控件

<ext:ResourceManager ID="ResourceManager1" runat="server">

 

完成配置之后，就让我们准备开始奇妙的Ext.NET之旅吧！
