我想获得一个带有 extjs4 和 ac# 后端的无限滚动网格......我在我的控制器中设置代理 api..

我的模型：

Ext.define('SCT.model.training.course.TrainingRequirementList', {
    extend: 'Ext.data.Model',
    idProperty: 'ID',
    fields: [
        { name: 'ID', type: 'int', convert: null },
        { name: 'EmployeeName', type: 'string' },
        { name: 'Description', type: 'string' },
        { name: 'StatusText', type: 'string' },
        { name: 'Status', type: 'int' },
        { name: 'Priority', type: 'string' },
        { name: 'Date', type: 'string' },
        { name: 'Cost', type: 'string' },
        { name: 'CanApprove', type: 'bool' },
        { name: 'CanRequest', type: 'bool' },
        { name: 'ConfirmStatus', type: 'string' },
        { name: 'PlanId', type: 'int'}
    ]

});

我的网格：

{
    xtype: 'gridpanel',
    flex: 1,
    padding: '0 10 10 10',
    minHeight: 200,
    verticalScroller: {
        xtype: 'paginggridscroller'
    },
    store: {
        model: 'SCT.model.training.course.TrainingRequirementList',
        pageSize: 200,
        autoLoad: true,

        remoteSort: true,
        sorters: {
            property: 'Date',
            direction: 'DESC'
        },

        proxy: {
            type: 'direct',
            extraParams: {
                total: 50000
            },
            reader: {
                type: 'json',
                root: 'ID',
                totalProperty: 'totalCount'
            },
            simpleSortMode: true
        }
    },
    columns:
        [{
            text: Lang.Main.Employeee,
            dataIndex: 'EmployeeName',
            flex: 1,
            filterable: true
        },
        {
            text: Lang.Main.Course,
            dataIndex: 'Description',
            flex: 1,
            filterable: true
        },
        {
            text: Lang.Main.Status,
            dataIndex: 'StatusText',
            flex: 1,
            filterable: true
        },
        {
            text: Lang.Main.Priority,
            dataIndex: 'Priority',
            flex: 1
        },
        {
            text: Lang.Main.Date,
            dataIndex: 'Date',
            flex: 1
        },
        {
            text: Lang.Main.Cost,
            dataIndex: 'Cost',
            flex: 1,
            filterable: true
        },
        {
            text: Lang.Main.Actions,
            flex: 1,
            align: 'center',
            xtype: 'actioncolumn',
            width: 50,
            items: [{
                icon: 'Design/icons/cog_edit.png',
                tooltip: Lang.Main.Open,
                handler: function (grid, rowIndex, colIndex, item) {
                    this.onGridOpen(grid.getStore().getAt(rowIndex));
                }
            }]
        }],      
    selModel: { mode: 'MULTI', selType: 'checkboxmodel' },
}

在控制器中设置代理：

view.grid.getStore().setProxy({
            type: 'direct', 
            model: 'SCT.model.training.course.TrainingRequirementList', 
            api: { read: SCT.Service.Training.Plan.GetFilteredRequirements }, 
            extraParams: { total: 50000 }, 
            reader: {
                type: 'json',
                root: 'ID',
                totalProperty: 'totalCount'
            },
            simpleSortMode: true
        });

关于我的观点的其他信息：

Ext.define('SCT.view.training.course.TrainingRequirements',
    {
        extend: 'Ext.panel.Panel',
        require: [ 'Ext.grid.PagingScroller', 'Ext.ux.grid.FiltersFeature'],

我的网格仍在一次加载所有数据（大约 8000 行......）......我已经搜索了解决方案并完成了教程......我仍然不明白。

请帮帮我……我完全不明白……

更新

这是我的 srv 请求： 在此处输入图像描述

并且响应得到了 3MB（大约 8k 个数据集......）..??

Your request dump shows that Ext effectively sends the limit param, so that's your server that is not handling it...

Just a piece of advice, but you should consider upgrading to last version of Ext, since buffered grid seems to have been simplified, and that will avoid you having to rework it if you eventually upgrade.
