Can you use jqGrid within ASP.net using a webservice and javascript?

The jqGrid has been kicking my butt (as well as others on this site). I can't seem to get the JSON data from the webservice to load into the jqGrid when using the addJSONData method.

Does anyone know if this is possible to do? I am not using MVC just a plain WebProject webservice in ASP.NET 3.5.

I am using the latest version of jqGrid 3.5.

I don't know what to do. I am currently trying to load just 1 row that I am returning a string in my WS like this:

"Page:1,Total:1,Records:1,Rows:[name: Jeff V title: Programmer]"

Which is then passed into my javascript as: {"d":"Page:1,Total:1,Records:1,Rows:[name: Jeff Vaccaro title: Progr开发者_StackOverflow社区ammer]"}

My jQuery code is the following:

    jQuery(document).ready(function () {
    jQuery("#list").jqGrid({
        datatype: processrequest,
        mtype: 'POST',
        colNames: ['Name', 'Title'],
        colModel: [
      { name: 'name', index: 'name', width: 55 },
      { name: 'title', index: 'title', width: 90 }
      ],
        pager: jQuery('#pager'),
        rowNum: 10,
        rowList: [10, 20, 30],
        sortname: 'id',
        sortorder: "desc",
        viewrecords: true,
        imgpath: 'themes/basic/images',
        caption: 'My first grid'
    });
});


function processrequest(postdata) {
    $(".loading").show();
    $.ajax({
        type: "POST",
        data: "{}",
        datatype: "clientside",
        url: "../webServices/myTestWS.asmx/testMethod",
        contentType: "application/json; charset-utf-8",
        complete: function (jsondata, stat) {
            if (stat == "success") {
                jQuery("#list")[0].addJSONData(eval("(" + jsondata.responseText + ")"));
                $(".loading").hide();
            } else {
                $(".loading").hide();
                alert("Error with AJAX callback");
            }
        }
    });
}

I've tried all sorts of different variations of the addJSONData code. Does anyone know if this is possible to do?

Any help is appreciated!

Thanks

First of all your web service should return a class instance with properties page, total, records, rows and so on. If web method has attribute [ScriptMethod (ResponseFormat = ResponseFormat.Json)] the class instance will be correct converted to the the JSON data.

You can use ajaxGridOptions: { contentType: 'application/json; charset=utf-8' } parameter and jsonReader (see http://www.trirand.com/jqgridwiki/doku.php?id=wiki:retrieving_data#json_data) to load data in the jqGrid. Information from Jqgrid 3.7 does not show rows in internet explorer and Best way to change jqGrid rowNum from ALL to -1 before pass to a web service could be helpful for you.

At the end imgpath is no more supported in version 3.5 of jqGrid.
