Mobile + MVVM View Refresh problem (only on iPad Safari)

Hi!
I have found very strange issue, which happens only on iPad Safari, on iPad Chrome not.
The Mobile Split view application has on the left pane mobile listview which switches views on the right pane, as in your example, but after each switching Ajax request is made (asynchronous) to retrieve data for selected view.

View elements are bound to view model with MVVM, for example
<div data-bind="text:value"></div> or <input data-bind="value:value"/> etc. and Ajax update with "set" method my view model.

Everything works good on Windows Chrome and Safari, except on iPad in Safari: sometimes MVVM DOM elements are not updated to the correct value. I'm sure the value was "set" in view model, but divs and inputs was not updated. Things I discovered in last two days:

1. If I change focus to input, that was not correctly updated, it becomes immediately correct value
2. if I change view to another and back,even without ajax, all divs and inputs are now updated
3. (this one very strange but true) divs and inputs, which bound value or text was previously empty string becomes updated!! divs and input fields, which previous value was something but not empty -becomes NOT updated!!

So for now I use very dirty workaround set each value first to empty string, and then set it to value that came with Ajax response.

Question: maybe you could somehow explain why?
About workaround - is there any possibility to refresh view, see point 2: change view to another and back updates all fields, and I could maybe call something after Ajax response is processed?

Again, the problem only occurs on iPad Safari. I have yesterday updated to iOS6, no difference.

Thanks in advance.

datasource object not ready in ajax OnSuccess call?

Hi,

I met a strange issue.

In DOM load, I create a kendo grid with remote data source:

$(document).ready(function () {

LocationGridDataSource = new kendo.data.DataSource({ type: "json" ...);

LocationGrid = ...

}

There is an ajax form in my page:

@using (Ajax.BeginForm("Bind", "Test", null, new AjaxOptions { OnSuccess = "BindOnSuccess" }, new { id = "BindForm" }))

{}

I use $("#BindForm").submit() to mannually submit the ajax form.
In BindOnSuccess, I use datasource.get:

function BindOnSuccess(context){

....

var location = LocationGridDataSource.get(context.id);

var selection = LocationGrid.table.find('tr[data-uid="' + location.uid + '"]');

....

}

Sometimes location which is got from LocationGridDataSource.get(context.id) is NULL, sometimes it will get object successfully.

After my debugging, my questions:
1. The problem is caused by LocationGridDataSource is not ready after ajax returns?
2. Is there a mechanism to ensure I can call LocationGridDataSource.get() based on a READY datasource object?

Any comments or instruction?

Thanks.

Fill grid cells based on selection made in other cell on the same row

Hi,

I'm evaluating Kendo components for use in a MVC web project. I'm very happy with the grid but now I run into a problem and I don't know from where to start.
I'm trying to create a view to enter invoices. For the invoice lines I use the kendo grid in batch editing mode. On each line I need to search for a product and fill the row cells with product code, product name and other details.
I started with a EditorTemplate attached to the first column "ProductCode".

columns.Bound(o => o.Product).EditorTemplateName("ProductItemDropDownList").ClientTemplate("#=ProductCode#");

The editor template contains a dropdowlist:

@(Html.Kendo().DropDownList()
   .Name("ProductCode")
    .DataTextField("ProductCode")
    .DataValueField("ProductId")
    .DataSource(dataSource => dataSource.Read(read => read.Action("GetProducts", "Invoice")).ServerFiltering(true))
)

The first problem is the cell remains empty after I select a product code. 
I expected to have there the code of the product.
The second problem, I have no idea how to fill the rest of the cells representing product description, ...

Thank you,
Flaviu Boldea

Scrolling a multi-axis line chart with static value axis

Hello,

we have a line chart similar to the Multi-axis line chart example in your demos (columns and a line) with two valueAxis. Everything works fine, but our data is too large and the multi-axis line chart consists of hundreds of columns.
The first of the two value axes should be placed at the beginning of the chart and the second at the end of it, and the problem comes here.When there are hundreds of columns in the chart, and the user scrolls the chart, the ValueAxis are scrolling too, and he/she should scroll to the end of the chart to see the valueAxis.Is there a way to scroll only the categoryAxis, but the two value axes to be static on the page?
