javascript - paging not moving to new data in kendogrid -

-

please note @ time new asp.net mvc, javascript , kendo. kendo grid paging works first 500 records returned, won't allow paging download more data server past 500. here controller:

    public actionresult executetestrule(string ruleid, string rulesql, string uwi, list<pdsmatchruleparam> parameters = null)     {         if (request.url != null)         {             var query = paginationquery.parse(request.querystring);             var upperlimit = query.fromupper;             var lowerlimit = query.fromlower;             var datasource = new matchdatasource();             list<dataaccess.dbparameter> dbparameters = null;             var generatedsql = datasource.generatequerysql(ruleid, rulesql, uwi, parameters, out dbparameters);             var results = datasource.executetestrule(ruleid, generatedsql, dbparameters, upperlimit, lowerlimit).select(u => new { uwi = u });             var response = new dictionary<string, object>();             response["result"] = results;             response["rowcount"] = matchdatasource.getrowcount(generatedsql, dbparameters);              return json(response, jsonrequestbehavior.allowget);         }         return null;     }

here total number of rows available "rowcount" in controller:

matchdatasource.getrowcount(generatedsql, dbparameters) 91637

here request.querystring in controller:

request.querystring {}     [system.web.httpvaluecollection]: {}     base {system.collections.specialized.nameobjectcollectionbase}: {}     allkeys: {string[0]}

pressing button has no effect:

here javascript code:

function bindtestruleresults() {     pagestate.selected.old.testruleresult = pagestate.selected.testruleresult;      var datasource = new kendo.data.datasource({         pagesize: 500,         data: pagestate.selected.testruleresult,         serverpaging: true     });     grids.testruleresultsgrid.setdatasource(datasource);     pagestate.selected.testruleresult = null; }  function inittestruleresultsgrid() {     $(ids.testruleresultsgrid).kendogrid({         autobind: true,         filterable: false,         navigatable: true,         pageable: {             refresh: true,             pagesizes: [10, 50, 100, 500],             buttoncount: 5         },         scrollable: true,         selectable: true,         serverfiltering: false,         serverpaging: true,         serversorting: true,         sortable: false,         columns: [             { field: "uwi", title: "uwi", width: "100%", attributes: { tabindex: "1" } }         ],          change: function() {             var selecteddataitem = this.dataitem(this.select());             if (pagestate.selected.testruleresult !== selecteddataitem.testruleresult) {                 pagestate.selected.testruleresult = selecteddataitem.testruleresult;                 testruleresultsselectionchanged();             }         },         editable: false     });     // add vertical scroll bars     $(ids.testruleresultsgrid + " .k-grid-content").css({         "overflow-y": "scroll"     });     grids.testruleresultsgrid = $(ids.testruleresultsgrid).data('kendogrid'); }  function exectestrule(uwi) {     $.ajax({         type: 'post',         url: "executetestrule",         contenttype: 'application/json; charset=utf-8',         data: json.stringify({             ruleid: pagestate.selected.ruleid,             rulesql: pagestate.sqleditor.rulesql.getvalue(),             uwi: "'" + uwi + "'",             parameters: pagestate.ruleparameters         }),         schema: {             errors: function(response) {                 return response.error;             },             data: function(response) {                 return response.result;             },             total: function(response) {                 return response.rowcount;             }         },         success: function(matcheduwilist) {             pagestate.testruleresult = matcheduwilist.result;              var datasource = new kendo.data.datasource({                 pagesize: 500,                 data: matcheduwilist.result,                 serverpaging: true             });             grids.testruleresultsgrid.setdatasource(datasource);             pagestate.selected.childuwi = null;             updatebuttonstates();         },         error: function(e) {             var errorobject = json.parse(e.xhr.responsetext);             var errormessage = errorobject.message;              //clear old error message              grids.testruleresultsgrid.clearerrormessage("error-message");              // add new error message             grids.testruleresultsgrid.adderrormessage("error-message", errormessage);         }     }); }

it has serverpaging = true in data source. missing? need somehow make pagesize dynamic in javascript code? tia.

update:

thank feedback, @brett. how i've simplified code suggested. how remove success: function outside of ajax part?

function exectestrule(uwi) {     $.ajax({         type: 'post',         url: "executetestrule",         contenttype: 'application/json; charset=utf-8',         data: json.stringify({             ruleid: pagestate.selected.ruleid,             rulesql: pagestate.sqleditor.rulesql.getvalue(),             uwi: "'" + uwi + "'",             parameters: pagestate.ruleparameters         }),         success: function(matcheduwilist) {             pagestate.testruleresult = matcheduwilist.result;              var datasource = new kendo.data.datasource({                 schema: {                     data: 'results',                     total: 'rowcount'                 },                 pagesize: 500,                 serverpaging: true             });             grids.testruleresultsgrid.setdatasource(datasource);             pagestate.selected.childuwi = null;             updatebuttonstates();         }     }); }

when exectestrule function run, error i'm getting:

enter image description here

you code confusing me, see 1 particular problem. not telling kendo ui datasource data , row count properties in returned object controller.

in controller, specify data located in response["results"] property, while row count in response["rowcount"] property. therefore, returned object looks this:

{   results: [...],   rowcount: 91637 }

the kendo ui datasource object's schema, default, expects data located in "data" property , row count (a.k.a. number of items in data) located in "total" property. since object not conform convention, need tell data source properties named differently.

var datasource = new kendo.data.datasource({   schema: {     data: 'results',     total: 'rowcount'   },   pagesize: 500,   serverpaging: true });

so, might doing already, defined it. defined on $.ajax() call. not correct. $.ajax() function not care schema. kendo ui datasource does.

kendo ui datasource api reference

jquery $.ajax api reference
