Coolite Cool Study 1 在Grid中用ComboBox 来编辑数据

 更新时间：2009年05月17日 09:39:04   作者：  
作为Coolite的第一个教程，我想展现给大家能够体现Coolite强大的例子（当然也比官方例子稍微复杂一点）。
官方有一个关于Grid CURD 的例子：http://examples.coolite.com/Examples/GridPanel/WebService_Connections/HandlerUsing/   我在其基础上稍微修改一下， 用ComboBox作为Grid的Editor：

 

先show一下效果给大家坚持看下去的动力：

关键代码：

复制代码 代码如下:

<ext:Column ColumnID="ContactName" DataIndex="ContactName" Header="Contact Name"
Width="150">
<Editor>
<ext:ComboBox ID="ComboBox1" runat="server" StoreID="stoContactName" DisplayField="Name"
ValueField="Name" TypeAhead="false" LoadingText="Searching..." Width="570" PageSize="10"
Editable="true" Mode="Remote" MinListWidth="200" ItemSelector="tr.search-item"
MinChars="1" MsgTarget="Side" TriggerAction="All" Grow="true">
<CustomConfig>
<ext:ConfigItem Name="tpl" Value="#{TplContactName}" Mode="Raw" />
</CustomConfig>
</ext:ComboBox>
</Editor>
</ext:Column>

由于ComboBox作为Editor，是不能直接配置模板的，所以模板要独立写：
复制代码 代码如下:

<ext:XTemplate ID="TplContactName" runat="server">
<div>
<table id="data_table" class="t1">
<thead>
<tr>
<th>
Name
</th>
<th>
Desc
</th>
</tr>
</thead>
<tbody>
<tpl for=".">
<tr class="search-item">
<td>{Name}</td>
<td>{Desc}</td>
</tr>
</tpl>
</tbody>
</table>
</div>
</ext:XTemplate>

再加上这个比较Cool的table样式就基本上完成了:
复制代码 代码如下:


body, table.t1
{
font-size: 12px;
}
table.t1
{
table-layout: fixed;
empty-cells: show;
border-collapse: collapse;
margin: 0 auto;
}
td
{
height: 20px;
}
h1, h2, h3
{
font-size: 12px;
margin: 0;
padding: 0;
}
table.t1
{
border: 1px solid #cad9ea;
color: #666;
}
table.t1 th
{
background-image: url(/extjs/resources/images/default/panel/white-top-bottom-gif/coolite.axd);
background-repeat: repeat-x;
height: 22px;
}
table.t1 td, table.t1 th
{
border: 1px solid #cad9ea;
padding: 0 1em 0;
}
table.t1 tr.a1
{
background-color: #f5fafe;
}

Enjoy yourself！

    ASP.net AjAX中的PageMethods可以将静态页方法添加到 ASP.NET 页中并将其用作 Web 方法。然后，无需创建单独的 .asmx 文件即可从该页中的脚本调用这些方法，就好像这些方法是 Web 服务的一部分。特别是在一些交互流程不复杂而调用次数和方法又比较多的情况下更为方便。因为PageMethods不需要我们再添加另外的WEB服务或Page来处理请求。
