Questions on Kendo UI for jQuery Forum

Hi guys

Is there a way to attach the same init method (beforeShow and show too) to all Views, without specifying on html? Or maybe a way to bind to an event that gets triggered from all Views?

I think a good way to solve this would be the possibility to specify the View init method through the Layout. I have many Views with the same Layout, and all of them use the same init and show method. If we could put that in the Layout, the markup would become simpler and more maintainable.

Thanks!

resize add, edit and delete icons

I am amending the CSS files to tailor buttons and screens to suit our company layout and it will be necessary to resize the icons depending on the amount of data on the screen. I have made some modifications which reduce the size of the text box and text, but I cannot successfully get the image icon to shrink. I have managed to remove the icon to just display text, but ideally I would like the button to either display the icon and text if the the button is big enough but just text if the button is small. At the moment when text only is displayed the text is off centre. My code for the button and the icon is as follows:
.k-button.k-button.k-button-icontext {
    /*background-position: top;*/
    font-style: normal;
    font-family: Calibri;
    font-weight: normal;
    font-size: small;
    border-image-outset: 0px;
    /*height: 16px;*/ /*font-size-adjust: inherit;*/
    vertical-align: top;
    text-align: center;
    white-space: normal;
    /*overflow: auto;*/
    margin: 0px,0px,0px,0px;
    }

.k-icon {
    /*fit:slice;*/
    /*background-image:none;*/
    display: inline-block;
    width:auto;
    height:auto;
    background-size:contain;
}
I also have another button which does not have an icon which needs to be the same size as these buttons which is why I need generic code to suit the row height.
As you can see I was experimenting with some other options - with the current settings the icon is not being displayed although I think there is enough room. Any suggestions of amending the code gratefully received.

Infinite Scrolling

I would love to see infinite scrolling make it into the roadmap at some point. This is essential UI, especially on mobile and the plugins that are out there haven't really nailed it down yet.

Just a thought...

Array of DataSource versus HierarchicalDataSource

Assuming your data only has two levels of depth, in which case would you favor an array of (objects containing a) DataSource versus a HierarchicalDataSource and vice versa?

In such a case, we are tempted to use option 1 because the DataSource is much better documented and easy to grasp than the HierarchicalDataSource but the HierachicalDataSource might have hidden benefits worth the learning curve.

triggering combo box events programmatically

I have a combo box set up to cascade to another combo box. This works. I have mapped both a change event and a select event in the "parent" - - both of which also work. I am planning to observer the state of the "parent" knockout via the knockout-kendo plugin. I expect this to work.

BUT - I need to be able to trigger the cascade programmatically, as well. That is, I need to programmatically change the selected index of the "parent". To test this in advance of mapping it in knockout, I have a test button that successfully changes the selected item in the "parent". So, this works.

Here is problem: neither the change event nor a select event are triggered in response to the following (which is in the test button click handler):

var cbx = $("select").data("kendoComboBox")

cbx.select(2);

That is, the combo box changes state but kendo is not triggering either of the events.

I have tried this in various fiddles (modifying a similar situation) and it does not work there either.

This is quite important to us, so please let me know if this is not supported.

Thanks

Basic SparkViz height?

I'm trying to figure out how to change the height of a basic sparkline. I've tried the following:

01.$("#hum-log").kendoSparkline({

02. type: "area",

03. data: [

04. 71, 70, 69, 68, 65, 60, 55, 55, 50, 52,

05. 73, 72, 72, 71, 68, 63, 57, 58, 53, 55,

06. 63, 59, 61, 64, 58, 53, 48, 48, 45, 45,

07. 63, 64, 63, 67, 58, 56, 53, 59, 51, 54

08. ],

09. height: 50,

10. tooltip: {

11. format: "{0} %"

12. }

13. });

But it did not seem to make a difference.

how to add combobox to Editor Template using Grid pop-up

Hello,i am a computer science student ,working for a small software company and totally newbie about KendoUI.
I have a MVC project that connects to database ,get and shows data's on KendoUI grid.I would like to use combobox on my custom editor template with KendoUI grid pop up.

There is Kendo combobox on Index page.It fetchs and shows records from db with selected column().
I am using Kendo grid - pop up as a interface.There are add,edit, and update buttons.When i click add or edit button pop up screen opens which is related to my custom template.Every command is working well(add,edit,delete)

The problem is when i add Kendo combobox to my custom editor template , it shows nothing on grid.Edit and delete buttons are missing and when i click to add button it shows this ajax code.It looks like some problem about rendering.

{"Data":[],"Total":4,"AggregateResults":null,"Errors":null}

Here is my Kendo combobox code:

@(Html.Kendo().ComboBox()

.Name("productComboBox") //The name of the combobox is mandatory. It specifies the "id" attribute of the widget.

.DataTextField("ALLERGYTYPE") //Specifies which property of the Product to be used by the combobox as a text.

.DataValueField("ID") //Specifies which property of the Product to be used by the combobox as a value.

// .Filter(FilterType.Contains)

.Placeholder("ALLERGYTYPE")

.DataSource(source =>

{

source.Read(read =>

{

read.Action("GetProducts", "AllergiesData"); //Set the Action and Controller name

})

.ServerFiltering(true); //If true the DataSource will not filter the data on the client.

})

Getting data controller for combobox -

public JsonResult GetProducts()

{

PHRDevEntities patient = new PHRDevEntities();

return Json(patient.PR_PATIENTALLERGY, JsonRequestBehavior.AllowGet);

}

Another controller to get,create ,update etc.

public ActionResult Get([DataSourceRequest]DataSourceRequest request)

{

return Json(DataAccess.Get(request), JsonRequestBehavior.AllowGet);

}

public ActionResult CreateSingle([DataSourceRequest]DataSourceRequest request, TEntity itemNew)

{

return Json(DataAccess.Create(request, itemNew.ToArrayFromObject(), false, ModelState), JsonRequestBehavior.AllowGet);

}

public ActionResult Create([DataSourceRequest]DataSourceRequest request, [Bind(Prefix = "models")]IEnumerable<TEntity> itemsNew)

{

return Json(DataAccess.Create(request, itemsNew, true, ModelState));

}

public ActionResult UpdateSingle([DataSourceRequest]DataSourceRequest request, TEntity itemUpdated)

{

return Json(DataAccess.Update(request, itemUpdated.ToArrayFromObject(), false, ModelState), JsonRequestBehavior.AllowGet);

}

public ActionResult DestroySingle([DataSourceRequest]DataSourceRequest request, TEntity itemToDelete)

{

return Json(DataAccess.Destroy(request, itemToDelete.ToArrayFromObject(), false, ModelState), JsonRequestBehavior.AllowGet);

}

My custom editor template:

@model KendoUIMvcApplication1.DATA.PR_PATIENTALLERGY

<strong>PR_PATIENTALLERGY</strong> <br />

<table width="100%" cellspacing="5" style="margin:20px">

<tr>

<td width="10%">@Html.LabelFor(model => model.PATIENTID)</td>

<td width="40%">@Html.EditorFor(model => model.PATIENTID)

@Html.ValidationMessageFor(model => model.PATIENTID)</td>

<td width="10%">@Html.LabelFor(model => model.DOCTOR)</td>

<td width="40%" >@(Html.Kendo().ComboBox()

.Name("productComboBox") //The name of the combobox is mandatory. It specifies the "id" attribute of the widget.

.DataTextField("ALLERGYTYPE") //Specifies which property of the Product to be used by the combobox as a text.

.DataValueField("ID") //Specifies which property of the Product to be used by the combobox as a value.

// .Filter(FilterType.Contains)

.Placeholder("ALLERGYTYPE")

.DataSource(source =>

{

source.Read(read =>

{

read.Action("GetProducts", "AllergiesData"); //Set the Action and Controller name

})

.ServerFiltering(true); //If true the DataSource will not filter the data on the client.

})

//.SelectedIndex(0) //Select first item.

)

@Html.ValidationMessageFor(model => model.DOCTOR)</td>

</tr>

<tr>

<td width="10%">@Html.LabelFor(model => model.ISACTIVE)</td>

<td width="40%" >@Html.EditorFor(model => model.ISACTIVE)

@Html.ValidationMessageFor(model => model.ISACTIVE)</td>

</tr>

</table>

I have also DataAccess methods to control data.I can post them if it is needed.
He is the almost same problem with me: stackoverflow
