Clearing a MVVM bound Kendo ComboBox value doesn't update the viewModel

I've setup a combobox with a viewmodel / kendo MVVM binding, however when using the clear method as mentioned in the API, the viewmodel is not updating.

Example source code below, to reproduce just click the clear button, the combobox will show "None", i.e. placeholder value, but the bindings don't update the viewModel's selectedId value.

Also, if the initial viewModel's selectedId is set as null, when picking a different value in the combobox, the selectedId will show '
[object Object]' instead of the set dataValueField value on the combobox. Is there a way to have the combobox correctly handle a transition from null > the selected item's id?

Source:

<body>

<div id="example" class="k-content">

<pre>

{

selectedId: <span data-bind="text: selectedId"></span>,

textbox: <span data-bind="text: textboxValue"></span>

}

</pre>

<input id="products" data-bind="value: selectedId"/>

<input id="textbox" data-bind="value: textboxValue"/>

<button id="clear" class="k-button">Clear</button>

</div>

<script>

$(document).ready(function() {

var viewModel = kendo.observable({

//selectedId: null,

selectedId: 2,

textboxValue: "lorem ipsum"

});

kendo.bind($("#example"), viewModel);

var data = [

{text: "12 Angry Men", value:"1"},

{text: "Il buono, il brutto, il cattivo.", value:"2"},

{text: "Inception", value:"3"},

{text: "One Flew Over the Cuckoo's Nest", value:"4"},

{text: "Pulp Fiction", value:"5"},

{text: "Schindler's List", value:"6"},

{text: "The Dark Knight", value:"7"},

{text: "The Godfather", value:"8"},

{text: "The Godfather: Part II", value:"9"},

{text: "The Shawshank Redemption", value:"10"},

{text: "The Shawshank Redemption 2", value:"11"}

];

$("#products").kendoComboBox({

dataTextField: "text",

dataValueField: "value",

placeholder: "None",

dataSource: data

})

.closest(".k-widget")

.attr("id", "products_wrapper");

$("#clear").click(function() {

$("#products").data("kendoComboBox").value(null);

});

</script>

</body>

Using standard INPUT with Kendo Mobile Style

Hi,

I am trying to use standard input controls such as type=text and the standard select drop downlist with kendo mobile and the default styles seem to place them in various non in-line places (i.e. text box over on right of screen down a bit and no outline etc), what is my best practice?

e.g. in a standard view div (I have also tried putting this into a listview li to see if it helps)

<div id="amountdiv">
                    Enter Amount :
                    <input type="text" id="amounttextbox" value="testing" /><a href="" data-role="button"
                        data-click="amounttextbox_click" data-icon="add">Save</a>
</div>

Do I have to sit down and work out how the mobile UI CSS is applied for each input and override them for each case?

Some of the output from firebug is -

.km-ios input:not([type="button"]):not([type="submit"]):not([type="reset"]):not([type="image"]):not([type="checkbox"]):not([type="radio"]), .km-ios select:not([multiple]), .km-ios .k-dropdown-wrap {

background: none repeat scroll 0 0 transparent;

border: 0 none;

color: #385487;

font-size: 1.1rem;

min-width: 6em;

outline: 0 none;

padding: 0.4em;

}

.km-root input:not([type="button"]):not([type="submit"]):not([type="reset"]):not([type="image"]):not([type="checkbox"]):not([type="radio"]), .km-root select:not([multiple]), .km-root .k-dropdown {

margin-top: -0.95em;

right: 0;

}

.km-root input:not([type="button"]):not([type="submit"]):not([type="reset"]):not([type="image"]):not([type="checkbox"]):not([type="radio"]), .km-root select:not([multiple]), .km-root .k-dropdown {

-moz-appearance: none;

font-size: 1.2rem;

}

.km-root input:not([type="button"]):not([type="submit"]):not([type="reset"]):not([type="image"]), .km-root select:not([multiple]), .km-root .k-dropdown {

line-height: normal;

margin-top: -0.5em;

position: absolute;

right: 0.8em;

top: 50%;

z-index: 1;

}

.km-root input {

-moz-user-select: text;

}

.km-root * {

}

.km-ios, .km-ios .km-button {

font: bold 0.9rem HelveticaNeue,sans-serif;

}

Or do I have to wrap them in a certain Mobile UI container or should I be using the Web UI Suite in conjunction with mobile somehow?

Hopefully I am missing something simple as still very new here :)

Thanks
Matt

Combined date and time picker

I need to combine the date and time picker into one input-field so the user can type date and time like this
2012-03-12 15:56:02 in a single box. When expanding the picker the date and time pickers can be shown separately, but the validator needs to accept both date and time. Is this possible with the Kendo kontrols?

Also I'd like to override the validator to allow me to type inn offsets. E.g. if the user types +1d the date/time should be Now() + 1 day.
If the user types -4h the date/time should become Now() - 4 hours. Ideally when re-focusing on the field the date/time should change back to the entered offset allowing it to be edited, then on blur change back to the new calculated date/time combo.

Drop "up" list?

Hey all,

I need to open the list "up" all the time, not just when the widget feels there is not enough room below itself.

Any suggestions?

Example using groups option

Can someone post an example using the 'groups' property of datasource? For example, the sample data structure and datasource schema/configuration.

groups: Function

Used instead of data function if remote grouping operation is executed. Returns the deserialized data.

I've tried structuring my data a couple of ways to enable the remote grouping but my listview doesn't bind, it just stays blank with no errors. I don't want my grouping to be configurable. Not sure if this property requires serverGrouping to be enabled or not.

Thanks

Use DataSource with SignalR

I was wondering if there was a way to create a Datasource using SignalR. I know that SignalR is a push design but is there a way to override the transport calls to make hub calls in SignalR?
