如何在Extjs 4网格groupHeader中显示分组值? [英] how to show grouped value in Extjs 4 grid groupHeader?

问题描述

我有一个像这样的网格

var groupingFeature = Ext.create('Ext.grid.feature.Grouping', {
    groupHeaderTpl: 'Invoice: {invoice_number} ({rows.length} Item{[values.rows.length > 1 ? "s" : ""]})'
});

{
xtype   : 'grid',
store   : Ext.getStore('invoice_items'),
columns : [
            { text: 'Invoice Number', flex: 1, dataIndex: 'invoice_number', hidden:true },
            { text: 'Item Code', flex: 1, dataIndex: 'item_code'},
            { text: 'Description', flex: 1.5, dataIndex: 'description' }
        ],
features: [groupingFeature]                                 
}

我使用隐藏的发票发票编号对这个网格进行分组，我得到这样的输出

im using hidden filed invoice_number to group this grid and i have the output like this

我想做的是在组标题中显示分组的发票编号.在extjs4中有可能吗?怎么做?

what i want to do is show the grouped invoice number in the group header. is it possible in extjs4? how to do it?

致谢

推荐答案

找到了解决方案.我虽然必须在这里输入组列名称

found the solution. i though i had to put group column name here

groupHeaderTpl: 'Invoice: {invoice_number} ({rows.length} Item{[values.rows.length > 1 ? "s" : ""]})'

但是一旦我将其替换为发票:{name}

but once i replace it with Invoice: {name}

组列的值.
