I am trying to get a listview filled with messages that reside in an array in the ViewModel. When i click on a category  the function updateMessages is called. (shown below)



updateMessages fills in the messagesViewModel:


Which then gets shown in the view like this:

The problem is that everytime I click on a category the array just keeps on filling up. I want to empty the array before adding new messages. I tried to add a clearMessage function in the viewmodel that executed: this.messages.length = 0. This cleared the array but in the view model you can still see all the old messages. How can I remove those messages everytime this view is called upon.

Hi,

I'm trying out MVVM binding on HTML for the first time and have come across a scenario which i cant find any examples of.

What i'm trying to do is bind a lot of controls on my view to the viewmodel so (like silverlight) if a control changes value, i can check the viewmodel has changed and raise a haschanges or a similar event. - and i think this is possible using the MVVM model.

I currently had the drop down control bind to the controller like so:

@(Html.Kendo().ComboBox()
                .Name("BusinessUnitComboBox")
                .Filter("contains")
                .Placeholder("Select Business Unit...")
                .DataSource(src =>
                {
                    src.Read(read =>
                    {
                        read.Action("GetBusinessUnits", "Home", new { CompanyId = ViewBag.CompanyId });
                    });
                })
                .DataTextField("Name")
                .DataValueField("BusinessUnitId")
                .Suggest(true)
                .HtmlAttributes(new { style = "width: 250px" })
                .Events(e => e.Change("BusinessUnitChanged"))

How would i be able to call this method using the MVVM way?

Currently i have:

<select data-role="combobox" data-text-field="Name" data-value-field="BusinessUnitId" data-bind="source: buSource, value: BusinessUnitComboBox"></select>

as the html and after reading a guide, i have the following as my script:

var viewModel = kendo.observable({
            buSource: new kendo.data.DataSource({
                transport: {
                    read: {
                        url: crudServiceBaseUrl + "/Products",
                        dataType: "jsonp"
                    },
                    parameterMap: function (options, operation) {
                        if (operation !== "read" && options.models) {
                            return {
                                models: kendo.stringify(options.models)
                            };
                        }
                        return options;
                    }
                },
                batch: true,
            }),
            BusinessUnitComboBox: null,
            hasChanges: false,
            save: function () {
                this.productsSource.sync();
                this.set("hasChanges", false);
            }
        });

Would someone be able to guide me or point me in the right direction on  how to bind to the controller as i've done using the kendo control itself and also how to use the parameterMap?



Thanks in advance.

There is a bug in Kendo Mobile where Kendo tries to be smart and work around the Mobile Safari bug where the footer obscures the bottom 20px in certain scenarios, which leads to a white strip appearing when run as a cordova application.

The Kendo workaround is defined in kendo.mobile.js as BROKEN_WEBVIEW_RESIZE ( line 16876 ). This line currently reads
        BROKEN_WEBVIEW_RESIZE = OS.appMode && OS.ios,
but it should probably be either 
        BROKEN_WEBVIEW_RESIZE = ! OS.appMode && OS.ios,
or OS.appMode has a bug that leads it to return the wrong value.

Either way, the bug leads to the 20px "correction" to take place, resulting in a 20px high white strip at the bottom of the app. 

This has been tested with cordova 3.3.1-0.1.2 and iOS 7.0.3 (simulator and device).

Thanks,

I have a kendo view that is bound to a kendo.observable with accept and reject actions.  When reject is selected, I pop up a modalview that includes an input which requires comments as why they are rejecting.  The modal has two buttons, Reject and Cancel.  If the users hits accept, I want to send the input back to the original views viewModel.  I also expect all execution to stop when the modal is open, but it continues to run.

Here is a snippet of the viewModel and the modal view.
vm: utils.showReject();

I'm so much frustrated using kendo mobile... there's so many issues. I'm not sure whether I'm coding bad,,,,

Here's my another problem....

when listview (binds to remote datasource) reaches end, and user can click the detail button from the list to see more information.
It works fine when listview didn't reach end, but when it reaches end (using 'load more' button) and user clicks the detail button to see more information, I get 



This error is generated when calling DataSource.fetch ...


any clue?

Is there a way to do two way binding for the selected item between a view model and a list view.

Currently I get the selected item by doing like below
but I also want if I change the selected item in the ViewModel for it to change in the view.

for the existing listview (datasource already binded), I want to change the existing datasource's (transport.read.url) and refresh the listview. 

I tried to look for any example codes, but couldn't find it. Any advise? or code example might help.

I have two series in a radar chart: one with the minimum values and the other with the maximum values.

I would like to get a radar chart with the area filled between the minium and the maximum values.

Actually the image should look like generating the area for the maximum values and cut away the minium value area...

How could I achieve that?

Thanks for any hint!

I am creating an app in which I dont want to use font glyphs as background images.

Trying to use an image instead was not that easy actually, it will  not show up.
what is the preferred way of doing this?

This is what I tried
