[Solved] Editable grid and asynchronous validation => value disapears

Example containing my problem:

http://dojo.telerik.com/oMuFE/3

Problem

When editing a grid row, the data from an input field disappears. This only happens when calling the editing row validator from custom code.

Steps to reproduce:

Add new record

Fill in a product name

go to the next field => validation of the productname is triggered and after 1500ms it is found to be OK

Click on the update button

=> The value disappeared!!

What am I doing?

The validation function is synchronous.

My call to check the value is asynchronous.

Javascript can't block..

I start the async call, set the message to "checking..." and return false => the validation message is shown

When the async call returns, I cache the result (in this example always true) and call the validate function once again.

This second time the function is called I can return synchronous.

This pattern is described in:

http://blogs.telerik.com/kendoui/posts/13-12-10/extending-the-kendo-ui-validator-with-custom-rules

in the chapter "Advanced Validation"

Question:

How can this be solved?

Is there a better way to achieve this?

Thanks in advance.

Binding to remote via JSON

Hi There, I am new to Telerik but would like to get this working. I have a JSON URL and i am trying to drill down and show all the results of the child nodes under each entry section. THough i cant seem to get this schema defined correctly. If i want to show fields from the lowest node in xml/json how do i define it. The child node examples dont make it clear. Below url is test data so feel free to use.

Thanks

SharePoint 2010 datasource

Hi,

I've been playing around with the Kendo UI datasource and have created a data plugin(?) for using the listdata.svc for SharePoint 2010, it is attached to this post as a zip file

it can be implemented using the following code

var dataSource = new kendo.data.DataSource({

type: "sharepoint",

transport: {

read: "_vti_bin/listdata.svc/Inventory"

},

schema: {

model: {

fields: {

Make: { type: "string" },

Model: { type: "string" },

Price: { type: "number" },

PictureUrl: { type: "string" }

}

},

pageSize: 5,

serverPaging: true,

serverFiltering: true,

serverSorting: true

});

I'm going to look at adding full CRUD functionality and will post any updates, this currently only does reading.

SharePoint 2010 listdata.svc ODATA implementation does not currently support JSONP, so this can only be used in the same domain.

Any comments or obvious errors please.

Full Height PanelBar

Is there any way to achieve a full-height PanelBar with per-group scrolling? Specifically, what I'd like to achieve is to have the space available to the PanelBar be predefined. When the PanelBar starts all the items should be collapsed at the top (as usual). When you open an item, the content space should expand to fill up the entire allocated space, not just what's needed for the content. The other titles should end up at the bottom of the allocated space below the new content. If the content is to large for the space, then a scroll bar should be added inside the content area (not outside over the whole PanelBar - otherwise you have to scroll to get to the other PanelBar headings).

I'm looking for the exact same behavior as in this example for the ASP.NET Ajax PanelBar:
http://demos.telerik.com/aspnet-ajax/panelbar/examples/functionality/scrolling/defaultcs.aspx

Is this possible with the Kendo PanelBar?

Select() for The Second Grid On The Same Page Won't Work

Hello,

I have a situation where I need to put two grid on a same page. The problem is that when I try to select the first row in the grid, the select() for the second grid won't work. I used the example in the Telerik document and it does the same thing. Is there any way to work around this?

exportPDF and Embedded Base64 PNGs

Hi

I am currently trialing your product. Everything is working, with the sole exception of an issue that occurs when attempting to export a diagram to PDF, which is a crucial requirement.

Part of the requirement is that all PNGs used in the diagram must be embedded using Base64 Encoding, rather than the source URL of the image

i.e.

group.append(new dataviz.diagram.Image({
      source: "data:image/png;base64," + BASE64_STRING,
      x: 9,
      y: 20,
      width: 38,
      height: 38
    }));

This is working nicely both on screen and when exporting the diagram to SVG. However, when exporting to PDF, the chart is rendered without the embedded images.

Any advice would be very much appreciated.

Page size dropdown hidden behind page footer.

We have a kendo grid that sits just above our page footer. The footer has a higher z-index than the grid. Because of this, when selecting the page size dropdown, some of the items are hidden behind the footer.

Is there a way to make the page size dropdown open upwards instead of down? We would prefer not to have to move the grid upwards away from the footer, as this would introduce empty space that is only there to give the page size dropdown something to open into.

Thanks!

Bindings cause leaks

Hello,

we have a problem with some memory leaks using the kendo MVVM Pattern. I try to explain it based on the following class:

var myClass = (function (_super) {

__extends(myClass, _super);

function myClass(ctx, folder, options) {

_super.call(this, ctx, folder, options);

this.containerRight = null;

this.viewModelRight = null;

}

myClass.prototype.init = function () {

var dfd = $.Deferred();

this.buildMenu().done(dfd.resolve).fail(dfd.reject);

return dfd.promise();

};

myClass.prototype.buildMenu = function () {

var _this = this;

var dfd = $.Deferred();

this.containerRight = this.container.find(".right");

this.viewModelRight = { items: new kendo.data.ObservableArray([]) };

kendo.bind(this.containerRight, kendo.observable(this.viewModelRight));

var selectViewViewModel = kendo.observable({

title: "test",

iconSource: "test",

iconStyle: "top: -270px; left: -73px;",

dataSource: [],

selectedValue: "",

selected: function (e) {

_this.doSomething();

}

});

this.viewModelRight.items.push(selectViewViewModel);

return dfd.resolve();

};

myClass.prototype.doSomething = function () {

};

myClass.prototype.destroy = function () {

_super.prototype.destroy.call(this);

kendo.unbind(this.containerRight);

};

return myClass;

})(vendor.Templates.TemplateBase);

The leak occures on

selected: function (e) {

_this.doSomething();

}

or on

selectViewViewModel.bind("selected", function() { _this.doSomething() });

//and

selectViewViewModel.bind("selected", _this.doSomething.bind(this));

Every access to a instancemethod or variable out of the viewmodel seams to cause a leak.

Directly in jQuery we could solve the problem with, but it has no impact on bindings within the kendo MVVM

something.bind("selected", _this.doSomething.bind(this));

Does someone know a solution for this problem?

Thanks in advance,

Michael
