I'm trying to change the Editors textarea cols property using the following

var onCollapse = function(e) {
$('#editor').attr("cols", 200);
var editor = $("#editor").data("kendoEditor");
editor.update();
};

$('#Splitter').kendoSplitter({
collapse: onCollapse,
panes: [
{ size: "300px", min: "100px", max: "300px", collapsible: true},
{ size: "400px" }
]
});

I know the event is firing and that the value is getting changed, but the editor size stays the same. Also I have try changing the editors css width property to no avail. Thanks

Grid - no row update with DropDownList component as editor

Hi,

First of all, let me congratulate you about these really nice set of controls, methods and properties !
Great work.

Now, about what brings me here is the following :

Situation :
One grid, inline row editing, server sorting, server paging
4 columns : 3 string, 1 bool
Straight forward.

$(document).ready(function()

{

$("#gridStatus").kendoGrid({

dataSource: {

transport: {

read: "/content/reference_tables/status/json.status.list.php",

update: {

url: "/content/reference_tables/status/json.status.update.php",

type: "POST"

},

destroy: {

url: "/content/reference_tables/status/json.status.delete.php",

type: "POST"

},

create: {

url: "/content/reference_tables/status/json.status.create.php",

type: "POST"

}

},

error: function(e) {

alert(e.responseText);

},

schema: {

data: "data",

total: "total",

model: {

id: "id",

fields: {

table_name: {

type: "string",

validation: { required: true}

},

status_name: {

type: "string",

validation: { required: true}

},

description: {

type: "string",

validation: { required: true}

},

active: {

type: "boolean"

}

},

pageSize: 10,

serverPaging: true,

serverSorting: true,

sort: { field: "table_name", dir: "asc" }

},

sortable: { mode: "single", allowUnsort: false },

pageable: true,

editable: "inline",

toolbar: ["create"],

columns: [{

field: "table_name",

title: "Table",

width: "25%"

}, {

field: "status_name",

title: "Name",

width: "20%"

}, {

field: "description",

title: "Description",

width: "35%"

}, {

field: "active",

title: "Active",

width: "100px",

template: "<div align=center>#= active #</div>"

},

{ command: ["edit", "destroy"], title: " ", width: "210px" }

]

});

Working situation :
All string columns are edited as a textbox. Works fine, row is updated, .. nice and smooth as designed.
In fireBug, on updating, I see that the update PHP page is called as it has to be.

Not working :
But the issue happens when I turn the first row editing is a drop down list

(...)

columns: [{

field: "table_name",

title: "Table",

editor: tableNameDropDownEditor,

width: "25%"

}, {

field: "status_name",

title: "Name",

width: "20%"

}, {

field: "description",

title: "Description",

width: "35%"

}, {

field: "active",

title: "Active",

width: "100px",

template: "<div align=center>#= active #</div>"

},

{ command: ["edit", "destroy"], title: " ", width: "210px" }

]

});

function tableNameDropDownEditor(container, options)

{

$.ajax({

url: "/content/reference_tables/status/json.status.table_names.php",

dataType: 'json',

success: function(items) {

$('<input id="idEditDropDown" data-bind="value:' + options.field + '"/>')

.appendTo(container)

.kendoDropDownList({

dataSource: items,

dataTextField: "table_name",

dataValueField: "table_name"

});

$("#idEditDropDown").data('kendoDropDownList').value(options.model.table_name);

},

error: function(data){

console.log('error occured loading the JSON');

}

});

}

This is the JSON returned by json.status.table_names.php :
(returns the list of the database table names filtered (select * except the one starting with .. bla bla and bla bla) )

[{"table_name":"audit_create"},{"table_name":"audit_visible"},{"table_name":"links"},{"table_name":"links_activity"},{"table_name":"msg_content"},{"table_name":"msg_flow"},{"table_name":"msg_status"},{"table_name":"ratings"},{"table_name":"shortlists"},{"table_name":"site_settings"},{"table_name":"users"},{"table_name":"vendor_websites"},{"table_name":"vendors"},{"table_name":"visitors"},{"table_name":"visitors_history"}]

Looks fine as the drop down populates the list.
So far so good, list is populated.

BUT .. the problem is that when I want to UPDATE the row !

As soon as I put a drop down list component, it does not update at all !
FireBug does not event show me the update PHP page called. It acts as no data has changed so it does not trigger the update process.
I am probably missing some things in the definition of the drop down ...
I tried with fixed values instead of filling it in with JSON .. but same behavior

If you please could assist a bit. It is propably a piece of cake but this starts to drive me crazy ;-)

Any help is welcome, obviously.

Wbr,

/Olivier

Popup editor: Save Changes

Hi,

I am using grid with custom popup editor template. When I press UPDATE button CRUD update request is working properly. However when I keep edit the other rows it is posting all data from the previous rows. And the data is growing after every UPDATE.

If grid is posting the update request when I click the Update button on popup editor, I think it doesn't need to send the data from previous row that already updated in the server.

What do you think?

Thanks!

Grid Grouping - Default a group as Collapsed

Hey All
When using a Grid and a grouped Data Source; is there anyway to make a group be collapsed by default (rather than expanded).

DataSource parameter ...

group: [{ field: "DepartmentName" }, { field: "EmployeeName"}],

I would love it if there was something like

group: [{ field: "DepartmentName", status: "exp" }, { field: "EmployeeName", status: "col"}],

I could always collapse each on load, but that seems cumbersome

pageSize()

I have a dataSource that is configurable by the user. Programmatically, that means I want to set the pageSize each time before I do the .read() on the dataSource.

But I am finding (version 515) using Fiddler that when I change the pageSize (the datasource fires off a read (with no parameters) and then when the read() happens a few lines later there is a second getURL request:

I want to configure the DataSource so that it is only fired manually.

Here is another oddity, this double HTTP Get only happens once. The next time I proceed through the code, setting pageSize() does not cause an HTTP Get, (only the .read() does).

Just to make this more clear the setting .pageSize() fires this request
GET /SearchBoxInRange HTTP/1.1

and two lines later the searchData.read() fires of this request:

GET /SearchBoxInRange?requestBox=((42.23903905725251%2C+-71.22695843505858)%2C+(42.49270487579739%2C+-70.90904156494139))&within=false HTTP/1.1

The second is the correct one. The first is spurious.

var pagesize = $("#PageSizeSelect").data("kendoDropDownList").value();

alert("page size is now: " + pagesize);

searchData.pageSize(parseInt(pagesize));

// makes a second request - which works and has the new pagesize set

// searchData is a kendo dataSource object

searchData.read(searchBox);

Grid not editable when using editable: {update: true}

I have an editable Grid.
When using just editable: true, the edit function behaves as expected.
However, when using editable: {update: true} the grid is not editable.

Is this a bug? If not, I'm posting my code below:

var dataSourceStatistics = new kendo.data.DataSource({

batch: true,

transport: {

read: {

data: {

f:'getOrderSuggestion'

}

},

schema: {

data: function(data) {

return data.result.custStats.Record;

},

total: function(data) {

return data.result.custStats.Record.length;

},

model:{

// TODO: id should be EmployeeId

id: "Employee",

fields: {

Employee: {

},

EmployeeId: {

},

ValueCultureAndExercise: {

type: "number",

defaultValue: "0",

validation: {

}

},

ValueExercise: {

type: "number",

defaultValue: "0"

},

Company: {

editable: false,

defaultValue: function() {

return "apa";

}

},

CompanyNo: {

editable: false

},

Department: {

},

Total: function () {

return this.ValueExercise * 10;

}

});

$("#orderGrid").kendoGrid({

dataSource: dataSourceStatistics,

editable: {

update: true,

destroy: true

},

sortable: true,

selectable: true,

toolbar: [{name: "create", text: "Lägg till rad"}],

columns: [

{

field: "Employee",

title: "Namn"

},

{

field: "EmployeeId",

title: "Anställningsnummer"

},

{

field: "ValueExercise",

title: "Värde träning"

},

{

field: "ValueCultureAndExercise",

title: "Värde träning och kultur"

},

{

field: "null",

title: "Totalt",

template: "#= ValueCultureAndExercise + ValueExercise#"

},

{

command: "destroy",

title: "Ta bort"

}

]

});
