Hello,

My testing code:  http://trykendoui.telerik.com/ObaV

It's happened When I created new task, and I want to edit it,
but I think the Popup window is not edit-window, 
because it doesn't have the 'Delete' button.

When I clicked the 'Cancel' button, 
the task I created would be removed!

It doesn't happen if I set dataSource with transport.
Does any configuration I need to set?

Thanks for your help,
Ming

There is problem with Cascading ComboBox in edit mode. When using for inserting new record – it’s working fine, allowing to choose City and then district in the city selected. When opening record for edit, then Child-ComboBoxFor is empty, although it has value assigned.
It seems that during initialization, Parent-ComboBoxFor reinitializing Child-ComboBoxFor and value is cleared. How to keep value during Edit?
I found some articles that similar issue was fixed in 2012 version and we are using latest version of Kendo UI for MVC.
Code sample is provided below.

Code for Parent-ComboBoxFor:

@(Html.Kendo().ComboBoxFor(model => model.CityId)
    .HtmlAttributes(new { id = Html.IdFor(m => m.CityId).ToString() })
    .DataTextField("CityName")
    .DataValueField("CityId")
    .Filter(FilterType.Contains)
    .DataSource(source =>
    {
        source.Read(read =>
            {
                read.Action(MVC.Object.ActionNames.Cities_Read, MVC.Object.Name);
            });
    })
)

Code for Child-ComboBoxFor:

@(Html.Kendo().ComboBoxFor(model => model.CityAreaId)
    .HtmlAttributes(new { id = Html.IdFor(m => m.CityAreaId).ToString() })
    .Placeholder("Choose area...")
    .DataTextField("Name")
    .DataValueField("Id")
    .Filter(FilterType.Contains)
    .DataSource(source =>
    {
        source.Read(read =>
        {
            read.Action(MVC.Object.ActionNames.GetCascadeCityAreas, MVC.Object.Name).Data("filterCityAreas");
        })
        .ServerFiltering(true);
    })
    .Enable(false)
    .AutoBind(false)
    .CascadeFrom(Html.IdFor(m => m.CityId).ToString())
)<script>
    function filterCityAreas() {
        return {
            cityId: $("#@Html.IdFor(m => m.CityId)").val(),
            cityAreasFilter: $("#@Html.IdFor(m => m.CityAreaId)").data("kendoComboBox").input.val()
        };
    }
</script>

i have a list view and it is getting populated with remote data, the kendoPage with the exact same datasource comes
back as no items to display.

HTML

Scripting



Any thoughts

Hello,

I created a small SPA using Kendo web and the MVVM pattern, but i'm having problems getting validation to work.
So i have a view which binds to a viewmodel using kendo.bind(view, viewmodel).
and example of a domain object (client side) would be like this:
and my viewmodel:
I'm using data-bind in my view to bind to my viewmodel.
Is it possible to apply a Kendo validator to my view using the rules from my Model ?

Thanks in advance.

See the attached image where there are two rows in the data set. One have 23 count and other having 0 count. When the pie chart is plotted and then clicked on the legend (that has 23 Count ) to deselect it the pie chart renders the 0 count in a weird way.

The expected behavior is that the Pie Chart is blank.

Pretty simple issue. I can do this. I can see that the 2nd modal opened but it is behind the first modal. I tried by setting z-order but it didn't seem to have an effect.

Any solutions?

Is there a way to preserve the UID of ObservableObject's in an ObsrevableArray passed to a TreeView's dataSource?

I want to have a TreeView and ListView that share some observables. This way changing one would change the other too. It works if I pass the same ObservableArray in and bind ListView second, but I want them to have slightly different subsets.

I have a jsfiddle demonstrating the issue: http://jsfiddle.net/zNLNy/1187/

Thanks

The first image is a dragging node image. I dragged the 'furniture'
parent node inside the 'storage' parent node. This dragged
successfully(see second image).

I don't want to allow this to happen. How can I prevent it?

Thanks.

Loading the page, all the user sees are the controls for the query criteria - some date ranges, some drop downs, some text boxes, some checkboxes, etc - and a big search button.  When they click on the search button, I create the Kendo grid and in the dataSource/transport/read, I get the criteria from the query criteria controls (in dataSource/transport/read/data) and send it to the server to get the grid of data.

Currently, whenever the user clicks on the search button, the same process is taking place, but that doesn't seem correct to me.  Should I be creating the grid each time?  Should I try to remove the grid from the DOM, if it exists, whenever I create the grid?  Why not just force a reload of the grid, and pull the data from the query criteria again?

What is the recommended Kendo practice for this?  Should I be calling $(selector).kendoGrid({...}); whenever the user clicks the search button?  If so, is there something I need to do to clean up the DOM before the call to kendoGrid if the grid already exists?

And does this apply to all Kendo widgets?

Thanks in advance.
