Questions on Kendo UI for jQuery Forum

Hello,

I have a grid that's being bound to a datatable and works fine with server requests. But once I try binding via ajax I get a circular reference error. I tried to use a helper method to convert the datatable into List<Dictionary<string, object>> and bind the grid to said collection, but I can't get that to work either.
My need to use a DataTable stems from a particular use case, let me illustrate:
The application enlists certain areas within a manufacturing process, each area has a list of part numbers/names; in a different form defects are being captured for particular parts. The grid must be rendered "dynamically" based on the part names listed for a particular area in the database, and the amount of defects for each part, like so:

Column 0 Column 1 Column 2 Column 3 Column 4
Defect Silicone seal FF Mask Headgear Swivel
Bubbles in functional area 0 0 0 3
Heterogeneous coloring 4 0 1 0
... ... ... ... ...

Column0 is fixed and must happen for all instances of the grid, the number of columns after this one depends on what I mentioned above, so the overall number of columns and member name/title will vary.
My first approach was to build a DataTable from the information retrieved from database, which works fine with server binding, but I'm stumped as to how to use ajax binding (which is needed for requirements not listed here). I've attached a sample project with my approach. Any suggestions?

Firefox Menu Loading Delay

Hi there,

I've got kendo (The web widgets) working across multiple pages and haven't really had any major issues getting it all to work the way I'd like across all browsers. Everything's displaying the way it's supposed to be and functioning great - that said there's one little thing I'd like to improve.

When I load any of my pages in firefox there's a split second delay in which I see my menu as an unordered list and unstyled (see before.png attached). It snaps into place with the proper styling(after.png) pretty quickly, but it's still an undesirable transition as everything on the page then shifts to position itself again.

This doesn't happen in Chrome or ie, on load the menu is styled before any elements are shown. Is this a firefox flaw, a jquery/javascript problem a kendo menu+firefox problem or just some kind of fault on my part?

Any suggestions are welcome,
Thank you

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
