hello

I have a difficult problem. that is how to get the igGridPaging PageSize

Code:

@Url.StyleHref("~/Styles/home.css")
    @Url.StyleHref("~/Styles/themes/base/jquery.ui.all.css")
    @Url.StyleHref("~/Styles/themes/base/infragistics.css")
    @Url.ScriptSrc("~/Scripts/jquery.js")
    @Url.ScriptSrc("~/Scripts/jquery-ui.js")
    @Url.ScriptSrc("~/Scripts/jquery.unobtrusive-ajax.js")
    @Url.ScriptSrc("~/Scripts/jquery.hotkeys.js")
    @Url.ScriptSrc("~/Scripts/jquery.validate.js")
    @Url.ScriptSrc("~/Scripts/jquery.validate.unobtrusive.js")
    @Url.ScriptSrc("~/Scripts/bg.core.js")
    @Url.JavaScriptLocalize()
    @Url.ScriptSrc("~/Scripts/infragistics.js")
    @Url.ScriptSrc("~/Scripts/infragistics.loader.js")
    @Url.ScriptSrc("~/Scripts/jquery.form.js")    

this is my javascript

then:

@using Infragistics.Web.Mvc;
<input type="button" value="GetData" id="btnGetData" />
<div id="igGrid">
</div>
<script type="text/javascript" language="javascript">
 
    var gridPageSize = 10; //每页显示条数
 
    $("#igGrid").igGrid({
        autoGenerateColumns: false,
        columns: [
                { headerText: "Number", key: "Number", dataType: "number" },
                { headerText: "Name", key: "Name", dataType: "string" },
                { headerText: "Year", key: "Year", dataType: "number" }
            ],
        dataSource: null,
        responseDataKey: "Records", //设置返回字符串中属于数据的字段
        responseTotalRecCountKey: "TotalRecordsCount", //设置返回字符串中属于数据总条数的列
        features: [
                {
                    name: "Paging", //使用分页
                    pageSize: gridPageSize,
                    type: "remote", //以返回的数据为主[必须]                   
                    recordCountKey: 'TotalRecordsCount', //设置返回字符串中属于数据总条数的列
 
                    pageIndexChanging: function (ui, args) {
                        //当页数发生变化之前[可不使用]
                    },
                    pageIndexChanged: function (ui, args) {
                        //当页数发生变化之后,需要分页的 请务必实现此方法,使用ajax方式,进行取数据
                        var pageNo = args.pageIndex;
                        PagingByNoAndSize(pageNo, gridPageSize);
                    },
                    pageSizeChanging: function (ui, args) {
 
                    },
                    pageSizeChanged: function (ui, args) {
                        gridPageSize = args.pageSize;
                        PagingByNoAndSize(0, gridPageSize);
                    }
                }
            ]
    });
 
    $("#btnGetData").bind("click", function () {
 
        $("#igGrid").igGridPaging("pageSize", 20)
        PagingByNoAndSize(0, gridPageSize);
    })
 
    function PagingByNoAndSize(page, pageSize) {
        $.ajax({
            type: "POST",
            url: '@Url.Action("GetData")',
            data: { "page": page, "pageSize": pageSize },
            success: function (data) {
                $("#igGrid").igGrid("option", "dataSourceType", "json");
                $("#igGrid").igGrid("option", "dataSource", data);
            },
            error: function (error) {
                alert(error.toString())
