Step 1: Create a primary DataGrid
[Html]
<Table id = "dg" style = "width: 700px; height: 250px "url =" maid "title =" DataGrid-SubGrid "singleselect =" true "fitcolumns =" true ">
<Thead>
<Tr>
<Th field = "itemid" width = "80"> Item ID </th>
<Th field = "productid" width = "100"> Product ID </th>
<Th field = "listprice" align = "right" width = "80"> List Price </th>
<Th field = "unitcost" align = "right" width = "80"> Unit Cost </th>
& Lt; th field = "attr1" width = "220" & gt; Attribute & lt;/th & gt;
<Th field = "status" width = "60" align = "center"> Status </th>
</Tr>
</Thead>
</Table>

<Table id = "dg" style = "width: 700px; height: 250px "url =" maid "title =" DataGrid-SubGrid "singleselect =" true "fitcolumns =" true ">
<Thead>
<Tr>
<Th field = "itemid" width = "80"> Item ID </th>
<Th field = "productid" width = "100"> Product ID </th>
<Th field = "listprice" align = "right" width = "80"> List Price </th>
<Th field = "unitcost" align = "right" width = "80"> Unit Cost </th>
& Lt; th field = "attr1" width = "220" & gt; Attribute & lt;/th & gt;
<Th field = "status" width = "60" align = "center"> Status </th>
</Tr>
</Thead>
</Table> Step 2: Set the detailed view to display the subgrid.
When using the detailed view, remember to introduce the header of the view script js file on your page.

[Html]
<Script type = "text/javascript" src = "http://www.jeasyui.com/easyui/datagrid-detailview.js"> </script>

<Script type = "text/javascript" src = "http://www.jeasyui.com/easyui/datagrid-detailview.js"> </script> [javascript] view plaincopyprint? $ ('# Dg'). datagrid ({
View: detailview,
DetailFormatter: function (index, row ){
Return '<div style = "padding: 2px"> <table id = "ddv-' + index + '"> </table> </div> ';
},
OnExpandRow: function (index, row ){
$ ('# Ddv-' + index). datagrid ({
Url: 'maid _ getdetail. php? Itemid = '+ row. itemid,
FitColumns: true,
SingleSelect: true,
Rownumbers: true,
LoadMsg :'',
Height: 'auto ',
Columns :[[
{Field: 'orderid', title: 'order id', width: 100 },
{Field: 'quantity ', title: 'quantity', width: 100 },
{Field: 'unitprice', title: 'unit price', width: 100}
],
OnResize: function (){
$ ('# Dg'). datagrid ('fixdetailrowheight', index );
},
OnLoadSuccess: function (){
SetTimeout (function (){
$ ('# Dg'). datagrid ('fixdetailrowheight', index );
}, 0 );
}
});
$ ('# Dg'). datagrid ('fixdetailrowheight', index );
}
});

$ ('# Dg'). datagrid ({
View: detailview,
DetailFormatter: function (index, row ){
Return '<div style = "padding: 2px"> <table id = "ddv-' + index + '"> </table> </div> ';
},
OnExpandRow: function (index, row ){
$ ('# Ddv-' + index). datagrid ({
Url: 'maid _ getdetail. php? Itemid = '+ row. itemid,
FitColumns: true,
SingleSelect: true,
Rownumbers: true,
LoadMsg :'',
Height: 'auto ',
Columns :[[
{Field: 'orderid', title: 'order id', width: 100 },
{Field: 'quantity ', title: 'quantity', width: 100 },
{Field: 'unitprice', title: 'unit price', width: 100}
],
OnResize: function (){
$ ('# Dg'). datagrid ('fixdetailrowheight', index );
},
OnLoadSuccess: function (){
SetTimeout (function (){
$ ('# Dg'). datagrid ('fixdetailrowheight', index );
}, 0 );
}
});
$ ('# Dg'). datagrid ('fixdetailrowheight', index );
}
}); When you click the expand button ('+'), The onExpandRow event will be triggered. We will create a new sub-grid and three columns. Remember to call the fixDetailRowHeight method for the primary grid, when the sub-grid data is loaded successfully

Then change the size.

Step 3: server code
Datagrid22_getdata.php

[Php]
$ Result = array ();

Include 'conn. php ';

$ Rs = mysql_query ("select * from item where itemid in (select itemid from lineitem )");

$ Items = array ();
While ($ row = mysql_fetch_object ($ rs )){
Array_push ($ items, $ row );
}

Echo json_encode ($ items );

$ Result = array ();
 
Include 'conn. php ';
 
$ Rs = mysql_query ("select * from item where itemid in (select itemid from lineitem )");
 
$ Items = array ();
While ($ row = mysql_fetch_object ($ rs )){
Array_push ($ items, $ row );
}
 
Echo json_encode ($ items); datagrid22_getdetail.php

[Php]
$ Itemid = $ _ REQUEST ['itemid'];

Include 'conn. php ';

$ Rs = mysql_query ("select * from lineitem where itemid = '$ itemid '");
$ Items = array ();
While ($ row = mysql_fetch_object ($ rs )){
Array_push ($ items, $ row );
}
Echo json_encode ($ items );

$ Itemid = $ _ REQUEST ['itemid'];
 
Include 'conn. php ';
 
$ Rs = mysql_query ("select * from lineitem where itemid = '$ itemid '");
$ Items = array ();
While ($ row = mysql_fetch_object ($ rs )){
Array_push ($ items, $ row );
}
Echo json_encode ($ items );
