Questions on Kendo UI for jQuery Forum

Following the advice in several forum posts, along with this jsbin created by Alexander Valchev, I am investigating the use of an observable object that provides HTML content to be rendered:
jsbin.com/iyakig/2/edit
If I add a second button to the code in the jsbin like this:
makeButton: function () {
var html = '<a data-role="button" data-bind="click: makeListView">Replace again</a><a data-role="button" data-bind="click: makeListView">Replace yet again</a>';
this.set("foo", html);
},

The second button does not get initialized as a widget as you can see here:
jsbin.com/iyakig/31/edit
Is there a limitation on MVVM binding of HTML code?

We have been using kendo.mobile.init() to initialize all widgets in the HTML generated by a template, but we are looking to use MVVM binding as suggested in this post. We would be very interested in knowing why additional widgets are not initialized as well as the advantages to this approach vs. the kendo.mobile.init() approach.

Assistance with locating x,y values in chart

I was looking at the code of Kendo Chart to find out how the points (for line chart) are plotted from a single dataItem. While researching I found out that you are using a Box2D method from where you are creating a property which contains (x1,y1, x2, y2) and with this property you are plotting the points with there average values.

I was unable to found out that from where you are retrieving these values (x1,y1,x2,y2). If you can please show me the path (function) from where you are converting these values then it will help me to find a solution.

Thanks.

How do I prevent a new Grid row from being created if current row is not valid

I'm using a grid in an MVVM environment. The grid that starts out with now rows. Once the Add New Row button is clicked the grid adds a row but the user can keep clicking the button and add new rows without any validation on existing rows. How can I either disable the New Row button, perform validation on the current row before adding a new row or client side validate all rows before trying to update to the server. I don't care if a user wants to add several rows and then edit the columns before saving the changes back to the server but I need to validate all required fields first.

Kendo grid and kendo window - creating custom kendo observable for the kendo window

Hello,

We are currently working on a kendo web project where we need to be able to have a button on a grid that opens a kendo modal window and then creates a custom viewmodel to be consumed by the current kendo window that can be passed into another kendo window. However, I can't seem to find a way to bind a ViewModel into the kendo window. Any help would be appreciated. Here is my code:

The problems that I know about are:

I don't know where to bind the observable to the window.
How to pass the same observable from window to window.

Thanks,

Colin

Change default categoryAxis labels and other chart formaters

Hi,

we are using several charts in our application. Due to internatiolaisation we want to change the label formatters for dates and other automatically rendered values.

As we don't want to edit every single chart instance by hand, we are looking for a way to set the default formatters and renderers globally.

How can we do it? Why ist it not described in the culture packages?

Thanks

Grid Filter

I have a search form beside the grid and when someone does a search I need it filter the grid. Is the below code how I would accomplish this or is this only a client-side solution? The filtering will happen on the server side. If the below code is also used server side filtering, how do I interpret the querystring on the GET request?

this.submitSearch = function () {

dataSource.filter(

{ field: "FirstName", operator: "eq", value: $('FirstName').val() },

{ field: "LastName", operator: "eq", value: $('LastName').val() },

{ field: "Email", operator: "eq", value: $('Email').val() },

{ field: "Phone", operator: "eq", value: $('Phone').val() },

{ field: "ReservationDate", operator: "eq", value: $('ReservationDate').val() }

);

}

public List< ChartData> ChartDataList {get;set;}

}
