Hi Everyone,
I'm quite new to Kendo UI Mobile on Icenium, and i'm currently trying to refresh the data i have on my mvvm viewmodel, basically i have a view model with a datasource and a function named showView: wich i would like to be called after the view is presented to the user, i tried seeking on the documentation but i wasen't unable to make raise data-show on my viewmodel. Could any one be so kind to provide me a working example, the viewmodel is created like the one on visual studio sample, with an added showView: function()..
I need this because i need to load fresh data from localStorage, do some stuff with it and populate the datasource to show a result on the screen.

Thanks
Sebastian

IE tries to download Json result

Hi,
I convert my MVC project to use Kendo UI. I have action result return simple Json object status with message if there is an error. It was working fine before I convert.
now it tries IE tries to download the Json, Firefox and Chrome will show it as text.

here is my code. I add ("text/html", System.Text.Encoding.UTF8, JsonRequestBehavior.AllowGet) I was hoping it will fix it but it didn't

return Json(new { Success = true }, "text/html", System.Text.Encoding.UTF8,
JsonRequestBehavior.AllowGet);

return Json(new { Success = false, Message = formPost.Message }, "text/html", System.Text.Encoding.UTF8,
JsonRequestBehavior.AllowGet);

form

Ajax.BeginForm(new AjaxOptions { OnSuccess = "handleModalSubmit" })

JS

function handleModalSubmit(result) {

if (result.Success) {
alert("Your request was sent Successfully");

}
else {
alert("There was problem sending your request");

}
}

[Solved] Event is incorrectly displayed, when showing business hours

Hi,
There's a bug in scheduler, which can be easily reproduced with your online demos.
- Choose the basic usage demo.
- Doubleclick an event, to get into edit mode
- Change the start Time to 5pm and the end Time to 7pm.
- Save the event.
- Click "show business hours"
As a result, the event is displayed throughout the whole day.
Any chance, to get a fix for that?

[Solved] Cannot get MultiSelect to retain values with MVVM

I am using the Multiselect widget along with Kendo MVVM. The tags are stored in an object that is saved to the database, this works fine when creating things.

But when retrieving them is a different story. I can add tags again, that is also fine, but when the item loads in from the database, it won't properly show the existing tag items that belong in the multiselect. So let's say I pull up an item with two tags. . { "Id": "tags/1", "Name" : "C#" }{ "Id" : "tags/2", "Name" : "Kendo UI" } .. these are not persisted into the multi-select box.

$widget = $element.kendoMultiSelect({

dataTextField: "Name",

dataValueField: "Id",

// define a custom template

dataSource: {

transport: {

read: {

dataType: "json",

url: $url

}

},

open: function (e) {

this.list.addClass("tag-cloud");

},

close: function (e) {

//e.preventDefault();

},

value: viewModel.get("Tags")

}).data("kendoMultiSelect");

<div style="width: 500px;">

<h2 class="fg-color-blueDeep">Tags</h2>

<div class="input-control" data-for="tags">

<select id="tags" multiple="multiple"

data-placeholder="Select Tags..."

class="dark tag-cloud"

data-bind="value: Tags"

style="width: 500px;"></select>

</div>

[Solved] Custom Editor with Inline Editing

Hi,

I am building a grid with inline editing and custom editors. I am wondering how to set the value of a field in this scenario. I don't think I want to use model.set in the change handler of my control, because I don't want to commit the data until the user clicks the "Save" button. Do I have to handle the save and cancel events myself to commit the entered data to the model (or not in the case of a cancel)? Or is there a built-in way to do this?

Thanks,
Steve

[Solved] e.model.isNew()

Hi,

I am using the e.model.isNew() to change the Title of the popup depending on whether Edit or Save is pressed.
That's working fine, I am however having an issue with then pressing the edit button to the added item.
The pop up is shown but with "Add", not "Edit" as the title.

If I refresh the page then it works as expected.

Code:
function onEdit(e) {
if (e.model.isNew()) {
// add
$(".k-window-title").text("Add");
} else {
// edit
$(".k-window-title").text("Edit");
}

}

Is there a way on the save event to specify that the model is no longer new?

function onSave(e) {
// set the model no longer as new ??

}

CRUD Create and Update Firing Twice

I'm using CRUD for my scheduler with an aspx web service. For the create and update event I am returning the created/updated event with the identifier in the json response, yet it is firing a second time as though something failed. The response from the service is OK, so I'm not sure what could be causing this.

What can I look at in the create/update complete event to tell if it added/updated the event? Or is there a check somewhere in the javascript that if failed will cause it to fire again where I can put a break point and see what is happening?

Thanks.

Show all columns programmatically?

I have a grid that I have added the ColumnMenu to that allows the user to pick which columns they would like to see. I am creating a "Reset" button that will restore the grid to its original state. How do I reshow ALL of the columns that are part of the datasource?

I need to somehow have an "ALL" because this grid is being built dynamically and different users will have different columns so I can't hard code the values in here...

Basically I just need to have something like this...

...
var grid = $('#ListAccountsGrid').data('kendoGrid');
grid.showColumn('ALL or *');
...

Anyone have any ideas?
