Hello,

We have a back end database that we interact with using a custom library. All the CRUD is in the form of GET / POST / PUT calls to our back end. The following is what we use to interact with our database:

db.get('some-record', function(resp) { });

db.put('some-record', { hello: 'world' }, function(resp) { });

db.post({ hello: 'world' }, function(resp) { });

db.destroy('some-record', { rev: 'abcdef123456789' }, function(resp) { });

The resp variable is a JSON object. Given the above, I have been able to successfully perform all CRUD operations on our database. Now, I would like to implement a Kendo GRID with Popup Editing as here: http://demos.kendoui.com/web/grid/editing-popup.html

How do I define the update, destroy and create functions using the functions above that interact with my database?

The part I do not understand is how the 'transport' works for updating in the demo code at the above link:

dataSource = new kendo.data.DataSource({
                            transport: {
                                read:  {
                                    url: crudServiceBaseUrl + "/Products",
                                    dataType: "jsonp"
                                },
                                update: {
                                    url: crudServiceBaseUrl + "/Products/Update",
                                    dataType: "jsonp"
                                },
                                destroy: {
                                    url: crudServiceBaseUrl + "/Products/Destroy",
                                    dataType: "jsonp"
                                },
                                create: {
                                    url: crudServiceBaseUrl + "/Products/Create",
                                    dataType: "jsonp"
                                },
                                parameterMap: function(options, operation) {
                                    if (operation !== "read" && options.models) {
                                        return {models: kendo.stringify(options.models)};
                                    }
                                }
                            }

Scrolling a splitter pane

Hi,

I have a treeview in a splitter pane with a breadcrumb above it. When I click a breadcrumb it navigates to that point in the tree and collapses that node. This will however cause the selected treeview node to be out of sight in the splitter pane. Is there a way for me to scroll the splitter pane so that the selected treeview node is displayed?

Thanks,
Jan Erik

KendoUI Mobile Examples Broken

Viewing on the iPad 3, only the main menu loads; there are no transitions, though when you click a button a 'loading' modal pops up. Further, it breaks the page when attempting further clicks.

Console message: Resource interpreted as Image but transferred with MIME

I keep seeing the following messages in Chrome's F12 console:

Resource interpreted as Image but transferred with MIME type application/octet-stream: "http://localhost:50659/webroot/Scripts/KendoUI/styles/BlueOpal/sprite.png".

    Resource interpreted as Image but transferred with MIME type application/octet-stream: "http://localhost:50659/webroot/Scripts/KendoUI/styles/textures/highlight.png".

It does not seems to effect anything.

Proper use of Batch Update against XML web service?

I am hoping someone can shed some light on the proper method for handling batch updates on a grid when the backend data source is an XML based web service.

Here are the particulars:

I would like to use the built in update, create and delete properties of the datasource transport, at the same time, I need to manipulate the data being sent to the web service from json to xml (the reader is json, the writer is xml). The caveat to this is I need to update the actual cell value being updated not a whole record (model) at a time. The problem with doing this strictly in the datasource (as far as I can tell) is that I cannot get details about which column changed only that the record (model) was updated.

Is there a way without putting in handlers within the KendoGrid to identify which fields have changed during the parameterMap callback so I can output just those individual values that have changed in a batch mode?

Here is what I did, but I would like to avoid putting a handler in the grid (if possible):

I put an event handler off the save property of the KendoGrid to record a list of changed cells. Then, on the ParameterMap of the data source, I go through the records and build the proper xml.

Is this the right approach or is there a better way to do this all within the datasource?

Here is my KendoGrid definition:

$(this._renderTo).kendoGrid({

dataSource: this.ItemsDS,

sortable: true,

pageable: true,

navigatable: true,

editable: true,

save: $.proxy( this.onCellChanged, this ),

columns: [

{ field: "Position.Name", title: "Position", width: 20 },

{ field: "Headcount.value", title: "Headcount", width: 15 },

{ field: "FTE.value", title: "FTE", width: 15 },

{ field: "EmployeeName.value", title: "EmployeeName", width: 50 },

{ field: "JobCode.value", title: "JobCode", width: 20 },

{ field: "JobTitle.value", title: "JobTitle", width: 100 }

]

});

Then, the onCellChanged:

onCellChanged: function (e) {

var isDirty = false;

var fieldName = e.container[0].firstChild.name;

if (!fieldName)

return;

var newValue = e.values[fieldName];

var oldValue = e.model[fieldName]

if (newValue != oldValue) {

var esResults = this.ItemsDS._pristine.EmployeeListResponse.Results;

elemName = fieldName;

// Create the record that will be sent back to TM1

this._employeeUpdates.items.push({

Scenario: esResults.Scenario,

Position: e.model.Position,

Employee: e.model.Employee,

EntityDept: esResults.EntityDept,

ProductLine_s: esResults.ProductLine_s,

Employee_m: { ID: elemName },

Value: newValue

});

e.container.data("oldValue", newValue);

}

},

And the datasource definition

this.ItemsDS = new kendo.data.DataSource({

transport: {

read: {

url: this._url + "/EmployeeList",

dataType: "json"

},

update: {

url: this._url + "/TM1ViewWrite",

dataType: "xml"

},

parameterMap: $.proxy(this._crudItemDS, this)

},

pageSize: 15,

schema: {

: : : : :

And finally the parameterMap (crud operations):

_crudItemDS: function (options, operation) {

if (operation == "update") {

if (this._employeeUpdates) {

return { events: kendo.stringify(this._employeeUpdates) };

};

}

return null;

},

NumericTextbox on Init

Hello,

I would want to know how can I create a event onInit for numerictextbox

I see that in the source of this control there is a function init and at the end of this function there is a kendo.notify(that), I would want to know if I can profit this notify to get some event OnInit.

Maybe if I add a trigger programatically in Init definition and at the end I put something like that.trigger("INIT");

Do you know the best way to do this? Maybe I could do something nice with events and people could create their own events. I need only an idea...

Is it possible?

Thanks in advance.

Slow loading on second TabStrip in the same page

Hello guys!

I have this weird extra delay added in loading two tabstrips on same page in my MVC project (kendo Q1 2012 release)
The tabstrips are configured using contentUrls and in the jquery 'ready' script i i call kendoTabStrip on both tabstrips one after another.

I'm running in Chrome browser and monitor using developer tools network tab.(got the same behaviour also in Firefox, all browsers latest version)
The request URL of tabstrip(X) loads normally (waiting=10ms, receiving=5ms)
But request URL of tabstrip(Y) loads with extra delay (waiting=9ms, receiving=234ms) !!!

I tried swapping the calling order of tabstrips but then i get same results, on calling of second tabstrip URL.
tabstrip(Y) loads normally (waiting=10ms, receiving=5ms)
tabstrip(X) loads with extra delay (waiting=9ms, receiving=234ms) !!!

So its not related to server side code, because each one if called first is fast but second consecutive call is extra slow.
And the data is not related from those two tabstrips so it be a deadlock at db level.

I have no clue why this is happening. Could surely appreciate your help guys.
