Kendo UI Server Bound Grid - UIHint and DisplayTemplate

Is it possible to make use of the UIHint attribute on a model property such as -

[Display(Name = "Days Late"), UIHint("_DaysToDate"), ReadOnly(true

)]

public int

? DaysLate 

{

get; set

; 

}

In order to specify a DisplayTemplate partial as a Template for grid data?

We have a fairly generic grid HTML helper method that uses model attributes whilst binding -

private static GridBuilder<dynamic> CreateDynamicGrid<TBaseViewModelType>(this HtmlHelper helper, string gridName, string provisioningControllerName, string formActionName = "Edit",

bool checkboxRowSelect = false

)

{

var type =

typeof

(TBaseViewModelType);

var modelProperties =

type.GetProperties().Where(p => p.IsScaffoldable()).ToList();



var

identityProperty = type.GetProperty("Id"

);



var idFieldName =

string

.Empty;

if (identityProperty != null

)

{

idFieldName =

identityProperty.Name; 

}

return

helper.Kendo().Grid<dynamic>()

 .Name(gridName)

.Columns(columns

=> {

columns.Template(t => t).ClientTemplate("<input

class='select-row' type='checkbox' />").HeaderTemplate(t =>

"<input class='select-all-rows' type='checkbox' />")

.Width(40).Visible(checkboxRowSelect);

columns.Template(t =>

t).ClientTemplate(helper.ActionLink(VisionWebResources.Action_More, formActionName,

provisioningControllerName, new { id = string.Format("#= {0} #", idFieldName) },

null).ToHtmlString()).Visible(identityProperty != null).Width("4em"

);

modelProperties.ForEach(p =>

columns.Bound(p.GetPrevailingType(), p.Name).Format(p.GetFormatString()).HtmlAttributes(p.GetHtmlAttributes()).Width(InitialColumnWidth));

})

 .DataSource(ds => ds.Ajax() 

.PageSize(15)

.Read(r => r.Action("Read"

, provisioningControllerName))

.Model(model => 

{ 

model.Id(

"Id"

);

foreach (var property in modelProperties) {model.Field(property.Name,

property.GetPrevailingType));

 }

 }) 

)

.Editable(ed =>

ed.Enabled(false

))

.Events(events => events.DataBound(

"function() { "

"if (typeof (gridDataBound) === 'function') { gridDataBound(); }" +

"}").Change("function() { "

+

"

if (typeof (gridFocusedRowChanged) === 'function') { gridFocusedRowChanged(); }

" +

 "

}")) 

.Filterable()

.HtmlAttributes(new { @class = "grid"

})

.Navigatable()

.Pageable(pages

=>

{

    pages.PageSizes(

new

[] { 15, 25, 40 });

    pages.Refresh(

true);

//Provides a button to refresh the current grid page

 })

.Resizable(resize => resize.Columns(true

))

.Scrollable(scrollable =>

scrollable.Height(425))

.Selectable(selectable =>

selectable.Mode(GridSelectionMode.Single))

.Sortable(sortable =>

sortable.AllowUnsort(false

));

 }

The grid has a dynamic model which is based partially on a fixed ViewModel and partially on dynamic fields which are created and managed by the users within the database (and thus cannot be known in advance). As such the binding is programmatic and not directly to a model. The dynamic fields do not require a display template, I simply wanted to provide some context around our approach.

The line that builds up the columns from the fixed ViewModel is-

modelProperties.ForEach(p => columns.Bound(p.GetPrevailingType(), p.Name).Format(p.GetFormatString()).HtmlAttributes(p.GetHtmlAttributes()).Width(InitialColumnWidth));

Can I add the "ClientTemplate" method to load a partial based on the UIHint value for the property, perhaps use @Html.DisplayFor(), or must this be explicit text?

Horizontal Scroling?

I would like my grid to be able to scroll horizontally when either the users browser is too small OR when they add additional columns using the Columns menu...

I have tried putting overflow-x:scroll on the surrounding div, but that solution has two problems.
1.) The footer (paging etc..) scroll with the data columns which looks crappy and is not wanted.
2.) The part of the grid that is not visible upon load is not styled, meaning that is has no alternating row colors on it when you start scrolling to the right.

Is there a Kendo supported Vertical scrolling property that I am missing?

Thanks
Jason

Setting month view to display 5 weeks instead of 6 (when appropriate)

I was asked to hide the first or last row in the month view when all the entries on that row are actually for the next or previous month. For example for the month of October 2013, the bottom row contains all days in November.

There is no out of the box way to do this but it's actually pretty easy. I'd like to share my solution and get feedback, please let me know is there is a better way to do it.

//define the cells and rows

var gridCells = $("td[role='gridcell']");

var gridRows = $("tr[role='row']");

//figure out if we should hide the first and/or last row

//class will be null if it's normal, otherwise 'k-other-month'

if (gridCells[6].getAttribute("class") != null) { $(gridRows[0]).css("display", "none"); }

if (gridCells[35].getAttribute("class") != null) { $(gridRows[5]).css("display", "none"); }

I call the above code in my 'dataBound' event handler because I refresh the datasource during navigation. The 'navigate' handler is probably more appropriate in most cases.

My only concern is that there are other possible classes for the gridcells which I am not yet aware of, which would cause the row to be unintentionally hidden. Maybe it would be better to check if the class is not 'k-other-month' instead of just looking to see if it is not null?

In-cell adding/ editing for Grid with row hierarchy or detail template

Hi Kendo UI Team,

I have a grid with dummy data and a client template. I'm attempting to add new records.

<div id="grid">

</div>

<script id="detail-template" type="text/kendo-ui-template">

<div>

<p>#: FirstName # #: LastName #'s age is #: Age #</p>

</div>

</script>

<script type="text/javascript">

$(document).ready(function(){

$("#grid").kendoGrid({

sortable: true,

editable: "incell",

toolbar: ["create"],

columns:[

{

field: "FirstName",

title: "First Name"

},

{

field: "LastName",

title: "Last Name"

}],

dataSource: {

schema: {

model: {

id: "Id",

fields: {

FirstName: {

type: "string"

},

LastName: {

type: "string"

},

Age: {

//data type of the field {Number|String|Boolean} default is String

type: "number",

// used when new model is created

defaultValue: 1

}

},

data: [

{

Id: 1,

FirstName: "Joe",

LastName: "Smith",

Age: 30

},

{

Id: 2,

FirstName: "Jane",

LastName: "Smith",

Age: 20

}]

},

detailTemplate: kendo.template($("#detail-template").html()),

dataBound: function ()

{

this.expandRow(this.tbody.find("tr.k-master-row").first());

},

});

</script>

Right now I can only edit the fields defined as grid columns, but not the field in the detail template. How can I fix this?

Event Text Color for Flat Theme

If I use the theme called Metro Black and have a resource that sets the background color for the event, the text color is either black or white depending on the background color. It is not somthing that I set, but seems to be handled in the css. If I change the theme to Flat, the text color is always white, even if the background color of the event is white and is therefore not readable.

Is there something I can do to make the Flat theme behave the same way as the Metro Black theme with regards to the event text color?

Thanks,

How to update scheduler majortick

Hi:

I'm trying to update the majortick during runtime
I have the following:

<script type='text/javascript'>

$("#doctors").change(function () {

var scheduler = $("#scheduler").data("kendoScheduler");

scheduler.majorTick(60); //interval of 60 minutes

kendo.bind($("#scheduler"), scheduler);
$("#scheduler").data("kendoScheduler").refresh();

});

</script>

Somehow, the code is not updating the intervals as a show in the code.

I appreciate in advance

Editable Grid manual dataItem.set() for checkbox binding is slow/delayed

As I have posted here I have a problem with setting dataItem.set() manually.

I have an editable Kendo Grid that may have a column with a checkbox to change a boolean value. I have used this solution proposed by OnaBai that is working perfectly!

The only problem is that the checkbox value change is too slow. When user clicks it, it takes about 1 second to change. I realize that the dataItem.set() method is responsible by this delay.

My grid has a considerable amount of data. About 30-40 columns and 300+ lines. It is defined as follows:

$("#mainGrid").kendoGrid({

dataSource: dataSource,

pageable: false,

sortable: true,

scrollable: true,

editable: true,

autoBind: false,

columnMenu: true, // Cria o menu de exibição de colunas

height: getGridHeight(),

toolbar: [/* hide for brevity */],

columns: [/* hide for brevity */],

dataBound: function() { /* hide for brevity. */},

edit: function() { /* hide for brevity. */}

});

Another detail is that, when dataItem.set() is called, it calls dataBound() event but that is not causing the delay. Grid's edit() method is not being called on this process. I don't know if worths to post dataSource code.

Any help will be very appreciate. Thank you in adv.
