rowTemplate, columnTemplates and flexible columns

We've been working on protoyping an application and would like to allow the user to have maximum flexibility to hide/unhide columns and perhaps reorder columns. I'm going to call this column manipulation.

We started out by using columnTemplates to format columns and column manipulation presented no issue.

However, we also want to be able to mark the entire row of the grid (i.e. when the item the row represents becomes "used") by assigning the whole row a CSS class or style (e.g. "opacity:0.30"), so we switched to a row template so that we could create the <tr> element and set its class according to a data value. We also created an alternate row template that differs only by adding the k-alt class. Works well.

However, if we allow the column menu to manipulate the list of columns, the rowTemplate (coded to expect a particular list of columns in a certain order) has a bit of an issue.

Do you have a suggestion for how to handle the whole-row decoration without using a row Template, or how to write a rowTemplate that is aware of the column manipulation?

In a somewhat related vein, is there an easy way for a columnTemplate to know what column it has been summoned forth to format? Say I want to use the same exact template for 2 (or more) columns. However, the columnTemplate is passed the entire model, not just the column to be formatted. No problem for a columnTemplate that only handles one column, but an issue for one that doesn't know which of the columns it should format data from.

The Grid will not load

Hi,

I am using MVC4 with Entity Framework 5 and I have the following piece of code that I got using samples posted on your website. Apparently, the Grid does not load at all. Am I missing something here?

I do want to mention that the Admin controller is in an "Admin" Area and I have routed requests to the Admin section correctly. Also the UnitOfWork object returns an IEnumerable object which I transpose to Kendo's DataSourceRequest. Currently, this function returns two objects in my test cases and I can see that when I go directly to the url that is bound to the read portion of the dataSource object.

Below is the Controller code.

Imports PropertyCentral.Domain.Entities

Imports PropertyCentral.Domain.Interfaces

Imports PropertyCentral.Domain.Repositories

Imports Kendo.Mvc.UI

Imports Kendo.Mvc.Extensions

Namespace Admin.Controllers

'<Authorize(Roles:="Administrator")>

Public Class UsersController

Inherits System.Web.Mvc.Controller

Private _uow As IUnitOfWork

Public Sub New(uow As IUnitOfWork)

If uow Is Nothing Then

Throw New ArgumentNullException("uow")

End If

_uow = uow

End Sub

'

' GET: /Admin/Users

Function Index() As ActionResult

Dim users = _uow.Users.SelectAll().AsEnumerable()

Return View("~/Areas/Admin/Views/Users/Index.vbhtml", users)

End Function

'

' GET: /Admin/Users/Users_Read

Function Users_Read(<DataSourceRequest()> request As DataSourceRequest) As ActionResult

Dim users = _uow.Users.SelectAll().AsEnumerable()

Return Json(users.ToDataSourceResult(request), JsonRequestBehavior.AllowGet)

End Function

End

Class

End Namespace

Here is the View:

@ModelType System.Collections.Generic.IEnumerable(Of PropertyCentral.Domain.Entities.User)

@Code

ViewData("Title") = "Administration/Users"

Layout = "~/Views/Shared/_Layout.vbhtml"

End Code

<div class="widget-box">

<div class="widget-title">

<span class="icon">

<i class="icon-th"></i>

</span>

<h5>Users</h5>

</div>

<div class="widget-content nopadding">

@*<div id="userGrid" style="height:380px;"></div> *@

@Code

Html.Kendo.Grid(Of PropertyCentral.Domain.Entities.User)(Model) _

.Name("UserGrid") _

.Columns(Sub(column)

column.Bound(Function(u) u.UserID)

column.Bound(Function(u) u.UserName)

column.Bound(Function(u) u.FirstName)

column.Bound(Function(u) u.LastName)

column.Bound(Function(u) u.EmailAddress)

column.Bound(Function(u) u.PhoneNumber)

End Sub) _

.DataSource(Sub(dataSource)

dataSource _

.Ajax() _

.Read(Sub(read)

read.Action("Users_Read", "Users", New With {.Area = "Admin"})

End Sub)

End Code

</div>

Could you please tell me why the Grid won't load the data?

Thanks,
Akshay

Editing an element on a sorted/filtered kendodatasource

Hi all, it seems that there is a weird bug when trying to edit an element on a sorted/filtered data source, both the element that will be in the previous position of the edited element and the edited element by itself in the new position gets updated with the new values.

I found that clearing the filter first and then resorting/refiltering will solve it.

datasource.filter([]);

var c = datasource.get(id);

c.set("Property", "New Value");

datasource.filter([{

field: "Property",

operator: "==",

value: "New Value"

}]);

ForeignKey column does not produce dropdown list in popup editing

I have a grid, with a detail grid and some of the fields in the detail grid refer to foreign key columns.When the editimode is set to inline this produces a dropdown list from which the user can pick a value. But if I change the editmode to popup the field is displayed as a textbox with the numeric key value instead of as a drop down list. Is this by design?

Is it possible for me to extend the Html Helper?
