Questions on Kendo UI for jQuery Forum

Hello,

First off, thanks for putting together a great suite of controls. You've made my life as a mobile environment developer much easier! I do have a question though. I see in the release notes and in the documentation that the mobile View supports an event called "beforeShow". Is there an example somewhere that utilizes that event? I'm trying to wire up some logic around the browser's back button and I'd like to use that event to determine if the user is logged in before displaying the requested view. When I try to attach a handler to the event like so:

<div data-role="view" id="someView" data-show="showSomeView" data-beforeShow="viewBeforeShow">

/* div content here */

</div>

The viewBeforeShow method never fires. The showSomeView event works as expected, but the user is able to navigate back to that view even though they are no longer logged in to the app (exactly the case I'm trying to prevent).

Here is the code for viewBeforeShow:

function viewBeforeShow(view) {

if(loggedOut == true) { // loggedOut is just a global variable for now

window.kendoMobileApplication.navigate('#loginView'); // loginView is the login mobile view

}

I don't know if this is the correct way to handle this scenario, but I can figure that out once I start handing the event.

I should mention I'm using the trial version 2012.2.710 (just downloaded it today). I will eventually translate this to the licensed version for my employer, but I was trying a proof of concept before I worried about that.

Is this the right way to configure the handler for this event? Any help would be greatly appreciated.

Thanks again for the great work!

How to add rows using MVC model

I have a models
Route:
int RouteID;
String RouteName;
IEnumerable<RouteCustomer> Customers;

RouteCustomer:
int RouteID;
int CustomerID;
int Sun;
int Mon;
int Tue;
int Wed;
int Thue;
int Fri;
int Sat;

Customer:
int CustomerID;
String Name;

I have created an edit form that allows changes (route name) and a grid for the customer information. What is happening now is that I am not getting the events I need when adding a new row to the grid:

Here is the grid code:

@(Html.Kendo().Grid<LightRouteDB.RouteCustomer>()

.Name("CustomerGrid")

.Columns(cols =>

{

cols.Bound(r => r.CustomerID);

//cols.Bound(r => r.Customer.CustomerName);

cols.Bound(r => r.Sun);

cols.Bound(r => r.Mon);

cols.Bound(r => r.Tue);

cols.Bound(r => r.Wed);

cols.Bound(r => r.Thu);

cols.Bound(r => r.Fri);

cols.Bound(r => r.Sat);

cols.Command(command => { command.Edit(); command.Destroy(); }).Width(200);

})

.ToolBar(toolbar => toolbar.Create())

.Editable(editable => editable.Mode(GridEditMode.InLine))

.Pageable()

.Sortable()

.Scrollable()

.DataSource(ds => ds

.Ajax()

.Events(events => events.Error("error_handler"))

.Model(m => { m.Id(p => p.RouteCustomerID); m.Field(f => f.RouteID).DefaultValue(Model.Route.RouteID); })

.Create(a => a.Action("CreateCustomerRow", "Routes"))

.Read(r => r.Action("ReadCustomerRows", "Routes"))

.Update(u => u.Action("UpdateCustomerRow", "Routes"))

.Destroy(d => d.Action("DestroyCustomerRow", "Routes"))

)

And here is the controller:

public ActionResult ReadCustomerRows(int id, [DataSourceRequest] DataSourceRequest request)

{

return Json(getRouteCustomersFromSession().ToDataSourceResult(request));

}

[AcceptVerbs(HttpVerbs.Post)]

public ActionResult CreateCustomerRow(int id, [DataSourceRequest] DataSourceRequest request, RouteCustomer customer)

{

if (customer != null && ModelState.IsValid)

{

IList<RouteCustomer> rc = getRouteCustomersFromSession();

rc.Add(customer);

}

return Json(new[] { customer }.ToDataSourceResult(request, ModelState));

}

[AcceptVerbs(HttpVerbs.Post)]

public ActionResult UpdateCustomerRow([DataSourceRequest] DataSourceRequest request, RouteCustomer customer)

{

if (customer != null && ModelState.IsValid)

{

IList<RouteCustomer> rc = getRouteCustomersFromSession();

var target = rc.Where(c => c.RouteCustomerID == customer.CustomerID).First();

if (target != null)

{

target.CustomerID = customer.CustomerID;

saveRouteCustomersToSession(rc);

}

return Json(ModelState.ToDataSourceResult());

}

The events in the controller just don't seem to fire. I thought I copied it from the sample programs, but it doesn't seem to work correctly. Any help would be appreciated.

Custom Tooltips for EACH "InsertHtml" item?

Does anyone know how to add tooltips for EACH "InsertHtml" item? Example: I want something like this.

    $(document).ready(function () {
        $("#editor").kendoEditor({
            tools: [
                "bold",
                "italic",
                "underline",
                "strikethrough",
                "fontName",
                "fontSize",
                "foreColor",
                "backColor",
                "insertHtml",
            ],
            insertHtml: [
                { text: "Request.FirstName", value: "#Request.FirstName#" toolTip: "Inserts users first name" },
                { text: "Request.BirthDay", value: "#Request.BirthDay#" toolTip: "Inserts users date of birth" }
            ]
        });
    });

[Solved] Remove view - parameterized

Edit: I have a typo in the thread title, it should be "Remote view..." not "Remove".

I am writing a mobile web app that leverages the Kendo UI Mobile 'Application' object. In one part of the application I am walking a user through selecting a vehicle (year first, then make, then model, etc). Each of these selections is on it's own page. Each list is retrieved from a back-end service. The 'make' depends on the 'year' selected, and the 'model' depends on 'year' and 'make'. I had built a small utility function that would parameterize the URL I send to the Kendo application's navigate() method and it was working great on version 2012.2.710. However, in another area I ran into this bug (http://www.kendoui.com/forums/framework/mvvm/bug-nested-array---source-binding.aspx) and was forced to upgrade to 2012.2.913. This fixes the bug but now there's some code in the navigate() method that strips of any query parameters from the url.

So, I was doing this:

app.navigate('/Home/SelectMake?year=2012');

and now (version 913) Kendo ends up basically doing this:

app.navigate('/Home/SelectMake');

So my question is this: Is there a recommended way to load remote views with parameters? If not, why was the code added that strips the query parameters when navigating (as this breaks my code now)?

Thanks.

[Solved] Resizing objects in panelbar cause panel height issues

I have found that if you put a paginated grid with auto height in the panelbar, when you change pages and the grid height changes, the panelbar doesn't keep up with the grid size changes. I suppose I could maybe detect when the grid page changes and somehow refresh the panel its in to fit maybe?

Dropdownlist in a Grid using ajax binding.

I'm asking this question again after spending additional hours trying to get this to work without success. I have a Grid using Ajax binding to display a dropdown list of items in a grid from a collection in the model. The items are on the server in a List<SomeItems> collection. This list is not in the model the grid itself is bound to - it is coming from a separate source. I'm really tired of mucking around with something that is very easy to do in every other tool kit I've ever used.

My code currently looks like this. I get no drop down list in my grid at all. I get an edit box.

@(Html.Kendo().Grid<Models.AutomationDevicePartsMapping>()

.Name("GridAutomationDevicePartsMapping")

.Columns(columns =>

{

columns.Bound(p => p.QuantityMultiplier).Title("Quantity");

columns.Bound(s => s.PartNumberName)

.Width(300)

.ClientTemplate(Html.Kendo().DropDownList()

.Name("PartNumberxyz")

.Events(ev => ev.Change("AutomationDeviceMappingDDLChanged"))

.BindTo(ViewBag.MeterParts)

.DataTextField("Text")

.DataValueField("Value")

.HtmlAttributes(new {style = string.Format("width:{0}px", 200)}).ToClientTemplate()

.ToHtmlString()

);

})

.ToolBar(toolbar => toolbar.Create())

.Editable(editable => editable.Mode(GridEditMode.InLine))

.Pageable()

.Sortable()

.Scrollable()

.Selectable(s => s.Mode(Kendo.Mvc.UI.GridSelectionMode.Single))

.DataSource(dataSource => dataSource

.Ajax()

.Model(model => { model.Id(p => p.AutomationDeviceId);

model.Field(p => p.PartNumberName).Editable(false);

})

.Create(update => update.Action("CreateNewAutomationDevicePartsMap", "AutomationDevice").Data("AutomationDeviceID"))

.Read(read => read.Action("GetAutomationDeviceMaps", "AutomationDevice").Data("AutomationDeviceID"))

.Update(update => update.Action("UpdateAutomationDevicePartsMap", "AutomationDevice"))

.PageSize(50)

)

Grid footer height expands on custom action mouseover/mouseout

This only happens in IE 9. I'm using the kendo silver style. I have a custom action in a grid. On mouseover and mouseout, the grid body height expands (right above the footer, but below the scrollbar). The template for the custom button also seems to remove the filtering options for the other columns.

Here it is in action (if you use IE 9!):
http://jsfiddle.net/xeyaT/

Do you guys have any idea why or how this might happen?
