[Solved] Refresh method with object as parameter

function onEdit(e) {

var id= $(e).attr("data-assumptionid");

var window = $("#EditAssumptionWindow").data("kendoWindow");

var assumption = findById(assumptions,id);

window.refresh({

data: {

ID: assumption.ID,

Term : assumption.Term,

type : assumption.Type,

unitID : assumption.UnitID,

Name : assumption.Name

}

});

window.open();

window.center();

}



Controller method

public ActionResult EditAssumption(Guid  ID, int Term, string Name, string type, int unitID)

        {

            ViewBag.Mode = "Edit";

            AssumptionDTO dto = new AssumptionDTO()

            {

                ID=ID,

                Name=Name,

                Term=Term,

                Type=type,

                UnitID=unitID

            };

            return PartialView("NewAssumption", dto );

        }

I am using the above to refresh the window when the user clicks an item and it works fine.

Is it possible to pass the object itself instead of each parameter individually? like below. I need to do this because the assumption object is going to have an array that needs to be passed in as a parameter also. Thanks,

function onEdit(e) {

var id= $(e).attr("data-assumptionid");

var window = $("#EditAssumptionWindow").data("kendoWindow");

var assumption = findById(assumptions,id);

window.refresh({

data: {

assumptionDTO: assumption

}

});

window.open();

window.center();

}



Controller method

public ActionResult EditAssumption(AssumptionDTO dto)

        {

            ViewBag.Mode = "Edit";

            return PartialView("NewAssumption", dto );

        }

date change event.

hello,

I'm working with a kendo datepicker. I created the control with a change event option.

When i run the page, if i already have a date in the input and y modifie it by adding some text to the input the change event is not fiered.

EX:

1- run code
2- the input has "12/12/2010"
3- add some invalid text to the end ex: "12/12/2010asdasd"
4- the input text of the input now is "12/12/2010asdasd"

the change event is not fiered.

When i do the same but instead of add text, select all the text with the mouse and then y wrote any thet to the input, the change event is fiered.

EX:

1- run code
2- the input has "12/12/2010"
3- select the input text with the mouse and write "asdasd"
4- the input text of the control now is "asdasd"

the change event is fiered.

is this the proper behaviour??

Regards
Guillermo

Can you set min/max using data-attribute initialization?

Kendo ver. 2012.2.710

I need to have multiple pickers (date and time) in a template that I call keno.init() on. In the template I'm using data-attribute declaration for the pickers. With data-attributes, can you set min/max for the pickers? I've tried, but Kendo doesn't like it.

Thanks.

[Solved] missing icons in tabstrip with platform=ios on android

Hi Kendos,

I'm playing with Kendo and ran in to a problem. When I try to force ios-look on Android mobile with this code

<script>
new kendo.mobile.Application($(document.body), {
platform: "ios"
});
</script>

all the icons in the tabstrip disappear and leave only a blue square. Same with data-icon used in listview. Are there any solution to this problem???

Destroying tab content

Hi folks,

maybe my question is a bit un-kendoish but i am thinking about performance during the lifetime of an application. My users can open as many tabs as they wish and close them, too. When a tab is removed its elements are removed from the DOM. What happens to the event handlers attached to them? Are they automatically removed as well to allow garbage collection of the no-longer-pointed-to objects?

Every time a tab is opened its page is downloaded and its 'code-behind' script is loaded into memory. In the Visual Studio Cassini you can see that these scripts are never unloaded from memory. Probably the objects created in the scripts will stay in the interpreter's scope forever, as they are interrelated with each other. What would be the best strategy to keep those leaks small? Putting as few code into these scripts as possible is probably a good idea, but what else? Delete everything by hand? Or is there any way to unload a script?

All the best
Kai

Is there a way to attach key value pair to node like you have in Treeview of ASP.NET MVC?
Something like this

new TreeViewItem
                                {
                                    Text = item.FirstName + " " + item.LastName,
                                    Value = item.EmployeeID.ToString(),
                                    LoadOnDemand = item.Employees.Count > 0,
                                    Enabled = true
                                };

Issue with setting combobox selected value via JQuery $('#select').val('new value')

Hello,
Anyone come across this issue where the combobox widget does not display the selected item when using JQuery.val to set selected value.
Steps to reproduce:
- Go to to the demo page: http://demos.kendoui.com/web/combobox/index.html
- Open the Firebug console or similar.
- Enter the following:
$('#select').data('kendoComboBox').value() --> outputs the current value: 'X-Small'
$('#select').val() --> Also outputs the same
$('#select').val('Small')

- Notice that the widget still displays 'X-Small', but both $('#select').data('kendoComboBox').value() and $('#select').val() return 'Small'

Thanks.

Selected node binding to VM?

Is there a way to bind TreeView's selected node to a MVVM view model?
If not, what are recommended or popular workarounds? Or should I give up MVVM and use TreeView without it?

How would I go about creating this query with the datasource?

http://services.odata.org/V3/Northwind/Northwind.svc/Customers()?$filter=Orders/any(o:substringof('alf',o/ShipName))&$expand=Orders

I currently don't see how I could get this to work with what is available. Thanks for the help in advance.
