1. Using Chrome, go here: http://demos.kendoui.com/web/grid/editing-popup.html 
2. Right-click and inspect element, and then search for the word 'window' (no quotes). Note that it finds 2 instances.
3. Click on Add new record, and then Cancel
4. Right-click and inspect element, and then search for the word 'window' (no quotes). Note that it now finds 8 instances. If you repeat 3 and 4, it will go up by 6 instances each time, which means that the DOM elements are being left when dismissing the popup dialog.

This is an issue for us because we are using a Template with some javascript to do some dynamic display of other controls based on a combobox value. Because of this issue, we aren't making the proper controls (in)visible because it is finding other instances of the controls from the other windows that are still in the DOM.

Can you suggest a workaround until this gets resolved? Thanks.

I had a treeview, I got the json data from server side, and tried to bind it to treeview, but it didn't work, return all "undefined", but the same data I copied them into local, then hard code them into the treeview, it work fine, why ?

 1) below is my code.
<script type="text/javascript">
    $(function () {
        $.getJSON('@Href("~/api/TrackingCodes/action/GetPageTree/?orgID=17&typeIds={\"1\", \"2\", \"10\"}")', function (ret) {
            var Sitetrees = new kendo.data.HierarchicalDataSource({
                data: ret,
                schema: {
                    model: {
                        id: "Value",
                        children: "Node"
                    }
                }
            });
            $("#DivPageTree").kendoTreeView({
                dataSource: Sitetrees,
                dataTextField: "Text"
            });
        })
    })
</script>


2) It works when I copied these data into local

<script type="text/javascript">
             var Sitetrees = new kendo.data.HierarchicalDataSource({
                data: [...................],
                schema: {
                    model: {
                        id: "Value",
                        children: "Node"
                    }
                }
            });
            $("#DivPageTree").kendoTreeView({
                dataSource: Sitetrees,
                dataTextField: "Text"
            });
</script>

Hey guys,

I was looking at the latest internal build (808), and it looked like you guys implemented RequestEnd on the DataSource, which is going to solve a number of problems I'm having in my app. So I set up the following code:


The problem is, this event appears to only fire on the first read. My grid is using a remote datasource in batch mode, and the event does not fire when I add, update, or delete a row (with the built-in toolbar buttons), nor does it fire when I hit the built-in refresh button in the footer.

Digging through the code, it appears the event is wired into the sync, success, and error functions... but the only place the success function appears to be wired into is the Read function on the RemoteTransport class. If you look at the create, update, and destroy methods on RemoteTransport, you'll see they don't appear to leverage the success or error functions at all... at least, not the way you would expect.

It seems to me that an easier implementation of all of this would be to modify the Transports to start the CRUD methods by throwing the requestStart event, then passing in wrapped success and error functions that work similarly to the existing read method, where requestEnd is thrown before the passed in success or error handler is executed.

Then, the dataSource would handle these events from the Transport, and re-throw them back down to the implementer.

So 1) is the feature in its current state considered complete?
2) Did I hit a bug or am I doing something wrong?
3) Does my explanation of a "better" approach make sense?

Thanks!

Edit: I was doing something wrong. Mental note: Next time, test new Kendo feature on page with one Grid, not seven. I pasted in the wrong GridID, to the bind function, so I was testing the results in a different grid than the one that was wired up. My bad.

Hi,

Is there a way to prevent Grid's AJAX call when no results are returned. Looks like this is the default behviour.

Thanks

I have an data model for a recursive parent-child relationship like this:

    public class ActivityCategory
    {
        public int CategoryID { get; set; }
        public string CategoryName { get; set; }
        public int? ParentCategoryID { get; set; }
        public ActivityCategory Parent { get; set; }

...

    }

The parent may be null.  I'm trying to set my grid up like this:
        @(Html.Kendo().Grid(Model)
                    .Name("ActivityCategoryGrid")
                    .Columns(columns =>
                    {
                        columns.Bound(resource => resource.CategoryName).Title("Name");
                        columns.Bound(r => r.Parent != null ? r.Parent.CategoryName : "");

which fails with
Bound columns require a field or property access expression.
How should I handle this?

 Please suggest me where I'm going  wrong . Following are codes I'm using :

 Thanks,

I think this was raised previously but I could not find it. Nested grids do not seem to have a way to handle field substition within a template region.

columns.Bound(o => o.Id).ClientTemplate("#=Id#");

If this is used within a nested grid this gets replaced prematurely by the Id of the parent row. Can anyone confirm 

If there is a work around for this
If this has been fixed because I am not seeing it working in the latest version

Thanks

I am having a problem getting column level filtering and sorting to work when using the html helper.

I assumed the following would be a column level override, yet this doesn't disable either sorting or filtering.
columns.Bound(o => o.Id).Sortable(false).Filterable(false)

If I don't add the filterable method to the grid then filters don't show for any columns.
//.Filterable()

Yet writing the Javascript by hand it seems setting the column level works. It seems like the column level isn't rendering the correct markup through the helper. Is there a way to access an existing grid and change these options I want to try to avoid rewriting the grids in Javascript which would not only be a pain but defeat the usefulness of the html helper.

I have tried accessing the current Javascript value for a given column to no prevail

var grid = $("#grid").data("kendoGrid");
document.write(grid.columns[1].filterable());
grid.columns[1].filterable(false);
grid.refresh();

I've seen references to "odata" and "aspnetmvc-ajax", but what are the others? I'm specifically looking for the default type that would be called manually in: kendo.data.transports["somevalue"]
