Kendo Grid Pager Shows No Items To Display

I have defined a Kendo grid as follows:
$(document).ready(function() {
$("#catalogGrid2").kendoGrid(catalogGridOptions);
});
let catalogGridOptions = {
pageable: true,
dataSource: {
serverPaging: true,
//serverGrouping: true,
transport: {
read: {
url: "/gliese/read",
type: "GET",
contentType: "application/json"
}
},
//pageSize: 25,
schema: {
data: "data",
total: "total",
// total: function(response) {
// return response.total;
// },
model: {
id: "catalogID",
fields: {
id: {type: "number"},
name: {type: "string"},
component: {type: "string"}
}
}
},
},
pageable: {
pageSize: 25,
//pageSizes: true,
//pageSizes: [10,25,50,100,"all"],
//input: true,
numeric: true,
refresh: true
},
columns: [
{
field: "id",
hidden: true
},
{
field: "name",
title: "Name",
width: 150
},
{
field: "component",
title: "Component",
width: 75
}
],
};
The data displays correctly in the grid, but there are no pages to navigate through, and the message "No items to display" is in the pager bar as well.
Below is an example of the results being returned:
{
"total": 3803,
"pageSize": 25,
"data": [
{
"id": 12409,
"name": "Sun",
"component": "",
"ra": "00 02 33.8",
"dec": "+00 16 42",
"properMotion": null,
"properMotionDir": null,
"radialVelocity": null,
"spectralTypeFull": "G2 V",
"spectralType": "G",
"spectralTypeSub": "2",
"luminosityClass": "V",
"visualMagnitude": -26.72,
"absoluteMagnitude": 4.85,
"parallax": null,
"bvColor": 0.65,
"hd": null
},
// 24 more results
]
}
Does anyone see any obvious reasons why the pager bar does not work?

NVC dxDataGrid buttons column causing compiler error

I am very new to NVC working on an existing solution. We are using a dxDataGrid, and I am trying to add a column with custom buttons. I am using the following documentation as reference:
https://js.devexpress.com/Documentation/ApiReference/UI_Widgets/dxDataGrid/Configuration/columns/buttons/
and
https://js.devexpress.com/Demos/WidgetsGallery/Demo/DataGrid/CommandColumnCustomization/jQuery/Light/
The existing implementation of the grid is as follows:
$(function () {
$("#branchDataGrid")
.dxDataGrid({
dataSource: {
store: dxMvcStore({
key: "ID",
})
},
showBorders: true,
noDataText: "No Branch Selected",
editing: {
mode: "batch",
allowAdding: false,
allowUpdating: true,
allowDeleting: true
},
paging: { enabled: true, pageSize: 10 },
showRowLines: true,
sorting: { mode: "none" },
columns: [
{
dataField: "Name",
caption: "Branch/Division Name",
validationRules: [{ type: "required" }]
},
{
dataField: "Code",
caption: "Code",
validationRules: [{ type: "required" }]
},
{
dataField: "ExternalCode",
caption: "External Code",
validationRules: [{ type: "required" }]
},
{
dataField: "OrderExchangeabilityTimeoutDays",
caption: "Return Window (days)",
dataType: "number",
editorOptions: {
format: "#",
min: 1,
},
},
{
dataField: "CollectionRequestMonthlyLimit",
caption: "Monthly Collection Limit",
dataType: "number",
editorOptions: {
format: "#",
min: 1,
},
validationRules: [{ type: "required" }]
},
],
onInitialized: e => {
self.companiesNodeDataGrid = e.component as DevExpress.ui.dxDataGrid;
},
onRowExpanding: e => {
// Only show one detail view at a time.
self.companiesNodeDataGrid.collapseAll(-1);
},
onRowInserting: e => {
// self.saveCompanyResult(e, true);
},
onRowUpdating: e => {
// self.saveCompanyResult(e, false);
}
}).dxDataGrid("instance");
});
I am trying to add my column with the buttons as shown in the documentation. Here is a snippet:
columns: [
{
type: "buttons",
buttons: [{
name: "save",
cssClass: "my-class"
}]
},
{
dataField: "Name",
caption: "Branch/Division Name",
validationRules: [{ type: "required" }]
},
{
dataField: "Code",
caption: "Code",
validationRules: [{ type: "required" }]
},
{
dataField: "ExternalCode",
caption: "External Code",
validationRules: [{ type: "required" }]
},
{
dataField: "OrderExchangeabilityTimeoutDays",
caption: "Return Window (days)",
dataType: "number",
editorOptions: {
format: "#",
min: 1,
},
},
{
dataField: "CollectionRequestMonthlyLimit",
caption: "Monthly Collection Limit",
dataType: "number",
editorOptions: {
format: "#",
min: 1,
},
validationRules: [{ type: "required" }]
},
]
The problem is that I am getting a compiler error in the line where it says "type: "buttons". Please see the below screenshot for reference:
I have done some searching but cannot seem to find any posts with similar issues. If anyone might have some advice for me where to look for a solution, or point out what I am doing wrong, I would be very grateful.

I have managed to continue using a different approach of adding custom markup to a column, as shown in the below link:

Display Kendo Chart (pie chart) based on grid data

I am using KendoUI - Grid component
How can I convert this into Kendo Grid:
For Eg:
I have created kendo grid (table) by using local data. As soon as I click on "Generate chart" button, above table's filter data should create the Kendo pie chart like below...
As I am new to Kendo, can somebody please suggest me the answer?
Code:
var localData = [
{
Id: 1,
userName: "John",
game: "A",
difficultyLevel: "Easy",
startTime: "25-05-2017",
endTime: "26-05-2017",
score: "210"
},
{
Id: 2,
userName: "Sam",
game: "B",
difficultyLevel: "Hard",
startTime: "04-11-2016",
endTime: "01-12-2016",
score: "4800"
},
];
var dataSource = new kendo.data.DataSource({
data: localData,
schema: {
model: {
fields: {
Id: {
type: "number"
},
userName: {
type: "string"
},
userName: {
type: "string"
},
difficultyLevel: {
type: "string"
},
startTime: {
type: "string"
},
endTime: {
type: "string"
},
score: {
type: "number"
},
}
}
}
});
$("#grid").kendoGrid({
dataSource: dataSource,
rowTemplate: $.proxy(kendo.template($("#rowTemplate").html()), dataSource),
scrollable: true,
height: 300,
sortable: true,
filterable: false,
groupable: true,
pageable: true,
columns: [{
field: "Id",
title: "Id",
filterable: true
}, {
field: "userName",
title: "userName"
}, {
field: "game",
title: "game"
}, {
field: "difficultyLevel",
title: "difficultyLevel"
}, {
field: "startTime",
title: "startTime"
}, {
field: "endTime",
title: "endTime"
}, {
field: "score",
title: "score"
}]
});
JsFiddle

You need to prepare your data to the chart's format. Something like:
$chartContainer.kendoChart({
dataSource: {
data: localData,
schema: {
parse: function(data) {
return data.map(x => {
return {
value: Number(x.score),
category: x.userName
}
});
}
}
},
series: [{
type: "pie",
field: "value",
categoryField: "category"
}],
tooltip: {
visible: true,
template: "#= category #: #= value #"
}
});

Ext.Direct grid problem

(i posted this on the extjs forum too but recon SO is probably busier)
HI
I'm passing down the following json to a direct store:
{
"type": "rpc",
"tid": 2,
"action": "DirectReportDesigner",
"method": "GetReports",
"result": {
"total": 1,
"data": [{
"id": 1,
"FullTypeName": null,
"title": "test",
"useGroupedColConfig": false,
"groupTextTemplate": "{'ProviderName': ' Contract Number -- {gvalue}','ProviderName': ' Provider Name -- {gvalue}'}",
"groupHeaders": null,
"groupFields": "['CostElement2', 'CostElement3', 'CostElement4']",
"groupedHeaders": false,
"jsonUrl": "report/BudgetManagerBudgetData.rails",
"menuType": "rptmid",
"actualType": "rptmid",
"ignoreCols": "1",
"getRowClass": "settings.utils.highlightRowWhenCellEmptyClass",
"deleted": false,
"fitToScreen": false,
"isCopyOf": 0
}]
}
}
here is what the js code looks like:
Ext.extend(Ideal.ReportDesigner.ReportGrid, Ideal.UI.BaseGrid, {
pageSize: 25,
afterRender: function() {
this.getStore().load({
params: {
start: 0,
limit: 25
}
});
Ideal.ReportDesigner.ReportGrid.superclass.afterRender.apply(this, arguments);
},
header: false,
view: new Ext.grid.GridView({
autoFill: true
}),
cm: new Ideal.UI.ColumnModel([{
header: 'Report Name',
id: 'nameCol',
sortable: true,
dataIndex: 'title'
}, {
header: 'Json URL',
sortable: true,
dataIndex: 'jsonUrl'
}, {
header: 'Group Text Template',
sortable: true,
dataIndex: 'groupTextTemplate'

]),
initComponent: function() {
var ds = new Ext.data.DirectStore({

},
fields: [{

}, {

}, {

}, {
name: 'fitToScreen'
}, {

}, {

}, {
name: 'isCopyOf'
}
],
remoteSort: true
});
var pager = new Ext.PagingToolbar({
store: ds,
displayInfo: true,
pageSize: this.pageSize
});
var config = {
store: ds,
bbar: pager
};
Ext.apply(this, Ext.apply(this.initialConfig, config));
Ideal.ReportDesigner.ReportGrid.superclass.initComponent.apply(this, arguments);
}
});
the grid renders ok, the server code to get the json fires ok, but the store never loads the data. i know it's being passed back as i can see it in firebug and that's how i pasted it above.
can anyone see anything obvious here?
cheers

I've always defined store's fields as an array of strings, not as objects.
fields: ['id','title','useGroupedColConfig', ...]

i managed to sort this - it was the name of the c# variable that was getting serialized that was throwing it - why i have no idea!!!
