The official has an example of grid curd: http://examples.coolite.com/Examples/GridPanel/WebService_Connections/HandlerUsing/I make a slight change on the basis of it, using ComboBox as the editor of the grid:

First show the effect for everyone to adhere to the momentum of watching:

Key code:

Copy Code code as follows:

<ext:column columnid= "ContactName" dataindex= "ContactName" header= "Contact Name"
Width= ">"
<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= "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>

Because ComboBox is a editor, you cannot configure the template directly, so the template is written independently:
Copy Code code as follows:

<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>

Plus this cool table style is basically done:
Copy Code code as follows:


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.T1st
{
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!
