I'm trying to get my footerTemplate working with a Kendo UI grid. I want to get the sum of 'hours_worked' in the footer of the tabel. I've tryed several options from the Kendo UI example but it doesn't work for me. What im doing wrong?
$(document).ready(function() {
$("#grid").kendoGrid({
dataSource: {
transport:
read: {
url: "mods/hours/data/get_hours.php?id=<?php echo $volunteer_id; ?>",
dataType: "json"
}
},
schema: {
model: {
fields: {
hours_id: { type: "number" },
volunteer_first_name: { type: "string" },
volunteer_last_name: { type: "string" },
hours_date: { type: "date" },
location_name: { type: "string" },
work_type_name: { type: "string" },
volunteer_id: { type: "number" },
hours_worked: { type: "number" }
}
}
},
aggregate:[{ field:"hours_worked", aggregate:"sum" }],
pageSize: 10
},
height: 350,
filterable: true,
sortable: true,
pageable: true,
selectable:true,
columns: [
{
title:"Naam",
template:"#=volunteer_last_name#, #=volunteer_first_name#",
},{
title:"Locatie",
field:"location_name",
},{
title:"Werkzaamheden",
field:"work_type_name",
},{
title:"Uren",
field:"hours_worked",
footerTemplate:"Sum: #=sum#",
},{
title:"Datum",
field:"hours_date",
},{
width:"200px",
title:"Opties",
filterable: false,
template:"<a href='?p=edit_reported_hours&id=#=volunteer_id#&hours_id=#=hours_id#' class='k-button'>Bewerken</a> <a href='?p=manage_reported_hours&o=delete&id=#=volunteer_id#&hours_id=#=hours_id#' class='k-button'>Delete</a>"
},
]
});
});
</script>
Add a curly bracket after transport and it will work.
transport: {
read: {
url: "mods/hours/data/get_hours.php?id=<?php echo $volunteer_id; ?>",
dataType: "json"
}
},

I use vue-good-table object to render table in Vue.js. I use paging and sorting serverside.

this.totalRecords = response.data.totalRecords;
this.rows = response.data.authorizations;
}).catch(err => {
this.$showError(err, true);
});
},
I have noticed that there are sent 3 requests to the server instead of 1: there are called methods like onPageChange, onPerPageChange and onSortChange but only the first time when my page is loaded. It is unnecessary. I have one method in "mounted" section where I load the first 10 results (sorting and paging by default). It's common, well-known problem with vue-good-table? Or maybe should I add an additional flag to not to invoke these 3 methods unnecessarily when the page is loaded?
Your onSortChange method is called at the table loading because you made a initialSortBy with specific values. To remove this calling juste remove
initialSortBy: {
field: 'id',
type: 'asc'
}
from you table configuration, but your sort will not be set, so I think this should be a legit function call.
The onPerPageChange and onPageChange are triggered by the config below
:pagination-options="{
enabled: true,
...
}
just remove the colon before pagination-options to have a config like this
pagination-options="{
enabled: true,
...
}

So far, I'm just trying to instantiate my kendogrid and passing through values from my view model. I got the following piece of code from Telerik's documentation for vb.net. The thing is, an exception is thrown from .Grid ->
"Type parameter for public overridable overloads function grid(of T as a class) as a gridbuilder(of t) cannot be inferred"
Html.Kendo().Grid().Name("kendogrid")
I'm not sure what this error means and I don't know how to go about fixing it.
View
$(document).ready(function () {
var dataSource = new kendo.data.DataSource({
transport: {
read: {
url: "TestAjax",
dataType: "json",
type: "GET",
},
update: {
url: "update",
dataType: "json",
type: "POST"
},
create: {
url: "CreateInvoiceRecord",
dataType: "json",
type: "GET",
},
parameterMap: function (options, operation) {
console.log(operation);
console.log(options);
if (operation !== "read" && options.models) {
return { models: kendo.stringify(options.models) };
}
}

The VB grid syntax from http://docs.telerik.com/kendo-ui/aspnet-mvc/vb#grid
is:
Html.Kendo().Grid(Of YourViewModelClassThatYouWantToBindTheGridTo)() _
.Name("grid") _
...additional configuration.
You are missing the part where you tell the grid what type of object you are binding to(the "Of NameOfYourClass" part.
You should post your whole grid definition.
Also...C# syntax is sooooo much cleaner(I know that's not helpful).
Edit
OK, so this question isn't about the correct VB.NET Razor syntax anymore....
This is how you get "extra" data passed to the controller methods from a dataSource: you use the dataSource.transport.read.data configuration (http://docs.telerik.com/kendo-ui/api/javascript/data/datasource#configuration-transport.read.data)
Using an object:
transport: {
read: {
url: "TestAjax",
dataType: "json",
type: "GET",
data: {
parameterToPassToReadAction: valueYouWantToPassToReadAction
}
},
Using a function:
transport: {
read: {
url: "TestAjax",
dataType: "json",
type: "GET",
data: extraDataFunction
},
function extraDataFunction () {
return {
parameterToPassToReadAction: valueYouWantToPassToReadAction
};
}
Where parameterToPassToReadAction is the name of the parameter in your server method and valueYouWantToPassToReadAction is the value you want it to be...which is stored where ever you stored it when the page loaded. If it is in a ViewModel of your vbhtml file and your javascript is in the script block of that same file, the syntax will be something like:
function extraDataFunction () {
return {
parameterToPassToReadAction: #Model.FieldYouWantToSend
};
}
But it is not clear where you have this value stored.
Finally got what I wanted working using a hack for create and then ajax for read. Not totally sure why this works the way it does so I'll need to look into it some more. I needed to pass parameters to controllers that are connected to kendogrid - specifically the read and create operations. I created a view model to store the values that I obtained from my Index controller and then used the view model to pass the values from kendogrid to the read and create operation controllers. For some reason, I was only able to pass parameters to the read operation using ajax.
Note: Still not the best solution. It calls readData controller twice and I don't want that.

In my model, I have the following code:
Ext.define('Proximity.model.CandidateblocklistModel', {
extend: 'Ext.data.Model',
requires: ['Ext.data.proxy.LocalStorage'],
config: {
store:'Proximity.store.CandidateblockStore',
fields: [
{ name: 'id', type: 'id' },
{ name: 'name', type: 'string' },
{ name: 'img', type: 'string' },
{ name: 'designation', type: 'string' },
{ name: 'summary', type: 'string' },
{ name: 'experience', type: 'string' },
{ name: 'industry', type: 'string' },
{ name: 'functionnml', type: 'string' },
{ name: 'role', type: 'string' }
],
proxy : {
type : 'ajax',
url : Proximity.util.Config.getBaseUrl() + '/index.php/candidate/getcandidateblock',
withCredentials: false,
useDefaultXhrHeader: false,
extraParams: {
"id": localStorage.getItem('id')
},
reader : {
filters: [
Ext.create('Ext.util.Filter', {
property: 'name'
})
]
}
}
}
});
The id in the local storage is already set before calling this model. I can see the id in localStorage by inspect element in Chrome, and I did get the value of it in other section. But I only can't get it in my model when I am trying to use it in proxy. I want to get data from my web service based on the value of the localStorage.
Code in my proxy:
extraParams: {
"id": localStorage.getItem('id')
},
I want to get the id from localStorage here.
Please help me.
I think the following code works
proxy : {
type : 'ajax',
url : Proximity.util.Config.getBaseUrl() + '/index.php/candidate/getcandidatebest',
withCredentials: false,
useDefaultXhrHeader: false,
extraParams: {
id: localStorage.getItem('id')
},
reader : {
filters: [
Ext.create('Ext.util.Filter', {
property: 'ind_id',
property: 'fun_id',
property: 'role_id',
property: 'id'
})
]
}
}
and then use the filtering facility of store to pass the localstorage value. To do that give filter permission remoteFilter: true, this.
Ahh i found an awesome trick. Instate of setting extraParams in your Model, set it in the store of the same model.
My new code is as follows.
Ext.define('Proximity.model.RecruiterbestlistModel', {
extend: 'Ext.data.Model',
config: {
store:'Proximity.store.RecruiterbestStore',
fields: [
{ name: 'id', type: 'int' },
{ name: 'name', type: 'string' },
{ name: 'img', type: 'string' },
{ name: 'company', type: 'string' },
{ name: 'summary', type: 'string' },
{ name: 'address', type: 'string' },
{ name: 'industry', type: 'string' },
{ name: 'functionnml', type: 'string' },
{ name: 'role', type: 'string' }
],
proxy : {
type : 'ajax',
url : Proximity.util.Config.getBaseUrl() + '/index.php/recruiter/getrecruiterbest/',
withCredentials: false,
useDefaultXhrHeader: false,
reader : {
filters: [
Ext.create('Ext.util.Filter', {
property: 'ind_id',
property: 'fun_id',
property: 'role_id'
})
]
}
}
}
});
Look i have removed the code
extraParams: {
"id": localStorage.getItem('id')
},
from Model. And in my store i have added
listeners: {
beforeload: function(store){
this.getProxy().setExtraParams({
id: localStorage.getItem('id')
});
return true;
},
So my new store code is as follows
Ext.define('Proximity.store.RecruiterbestStore', {
extend: 'Ext.data.Store',
alias: 'store.recruiterbeststore',
config: {
model: 'Proximity.model.RecruiterbestlistModel',
autoLoad: true,
remoteFilter: true,
storeId: 'recruiterbeststore'
},
listeners: {
beforeload: function(store){
this.getProxy().setExtraParams({
id: localStorage.getItem('id')
});
return true;
}
}
});
And its solved my problem.
But now i am having another issue. after running sencha app build native(using cordova bild), again i am having same issue, the extraParam are not added to proxy request.
Please help me to solve this.
For example, I have a view with model IEnumerable<Correspondence>. I want to bind it to KendoUI grid. What should I do? I've tried
#model IEnumerable<Correspondence>
<div id="Correspondence"></div>
<script>
$(document).ready(function () {
$('#Correspondence').kendoGrid({
dataSource: {
data: #Html.Raw(Json.Encode(Model)),
editable: { destroy: true },
batch: true,
pageSize: 15,
schema: {
model: {
id: "Id",
fields: {
Subject: { type: "string" },
CorrespondenceType: { type: "number" },
SentDate: { type: "date" }
}
}
}
},
navigatable: true,
selectable: "row",
filterable: true,
sortable: true,
pageable: {
refresh: true,
pageSizes: true
},
columns: [
{
title: "Subject",
field: "Subject"
},
{
title: "Type",
field: "CorrespondenceType"
},
{
title: "Sent Date",
field: "SentDate",
format: "{0:MM/dd/yyyy}"
},
{
command: [{ name: "openCorrespondence", text: "Open", className: "k-grid-openLaboratory", imageClass: "k-icon k-i-maximize", click: Open },
{ name: "deleteCorrespondence", text: "Delete", className: "k-grid-deleteLaboratory", imageClass: "k-icon k-delete", click: Delete },
{ name: "EditCorrespondence", text: "Edit", className: "k-grid-editLaboratory", imageClass: "k-icon k-edit", click: Edit }],
title: "Action"
}
]
});
}); // end ready
</script>
But it doesn't work. The table even doesn't show up. Please help me. Thank you.
Edited!!!
I have solved my own problem. Because I used command column, so I have to add 3 functions: Open, Edit, and Delete. Then, the grid showed successfully.
