Hierarchical Kendo UI Grid show/hide base on user security

Hi,

I manage to implement an hierarchical Kendo UI Grid successfully. However the specifications for the application that I'm building requires that the child grid be only displayed if the current user have the authorization. How can I achieve this?

How to remove the UTC component when date time is displayed in the Razor Grid ?

Hi,

I am using the KendoUI Razor grid in my application with the following Settings :

@model BMS_RDM_DTO.SnapshotGridData
@(Html.Kendo().Grid(Model.NewRecordsGridData)
.Name("NewRecordsGrid")
.Columns(columns =>
{
columns.AutoGenerate(true);
columns.Command(command => command.Custom("Edit").Click("EditNewRecordGrid")).Title("Actions");

})
.Filterable()
.HtmlAttributes(new { style = "height: 380px;" })
.Scrollable(scroll => scroll.Enabled(true))
.Groupable()
.Sortable()
.Pageable(pageable => pageable
.Refresh(true)
.PageSizes(true)
.ButtonCount(5))
.DataSource(dataSource => dataSource
.Ajax()
.PageSize(10)
.ServerOperation(false)
).Resizable(resize => resize.Columns(true))
)

I have an issue with the dateTime format shown on the grid. Please refer the screenshot - I dont want the UTC component to be shown. I would like to see just the date and the time without the offset / timezone difference.

What settings/config are required to achieve this ? Can I set the date time formatting for the grid itself in the CSHTML ? (I can't set it for individual columns because autobind=true)

Hi All,

I am using kendo tabstrip in my mvc application and used knockout js to bind data. The tabstrip is inside a kendogrid detail template. and data for all tab loads on detailrow init function of grid.When expanding detail row, first tab is active and it shows data. But when I select a different tab, it is showing empty content area. This issue comes in IE8.

Anyone have idea on why this happens?

Custom Command in Grid with Ajax Binding in Command Column - How to Do?

Dear KendoUI Team!
Is it possible to realize s.th. like this with KendoUI when using AJAX Binding?

columns.Command(commands =>
{
commands.Edit().ButtonType(GridButtonType.Image);
commands.Delete().ButtonType(GridButtonType.Image);
commands.Custom("CopyItem")
.Action("CopyItem", "Le")
.Ajax(true)
.HtmlAttributes(new { id = "CopyItemDetails" })
.DataRouteValues(route => route.Add(i => i.Rid).RouteKey("ItemID"))
.ButtonType(GridButtonType.Image)
;

}).Title(Strings.Commands).Visible((bool)ViewData["Writable"]);

What I found is that the custom command should be replaced by a column template. But I want the copy command in the command column, not in a separate column. And I need the ItemID of the row, of course.
How can I realize this with KendoUI?

Checkboxes in kendo grid

Hello, I am not sure if I have this right, but I have a grid with multiple records in it. I have added a checkbox to the grid so that the user can select the records they want to update. What I want to happen is for selected records to be updated with a value selected in a combobox from the form. I have the checkboxes displaying fine on the grid with this line of code.

columns.Template(@<checked>@Html.CheckBox("selected", new { id = @item.ID })</checked>).Title("Select");

the problem is when the update button is clicked I do not know how to iterate through the rows in the kendo grid from the controller and grab those records that will be updated .

I tried something like this but cant get it to work "Cannot convert type char....

foreach (GridRow<Bin_BudgetView> row in fc["kendoGrid"])

Can someone please give me a simple solution to iterate through a kendo grid from the controller and update those records that are checked?

Also If I wanted to check or uncheck all of the records in the grid how would I go about that?

thanks for your help

Changing from standard view to grid

I have put together a simple app which include a few or the "out-of-the-box" index views. I would like to swap the table in these views for the Telerik grid.

I have the following action in the controller:

// GET: Assets

public ActionResult Index()

{

var assets = db.Assets.Include(a => a.Equipment).Include(a => a.Owner).Include(a => a.ServiceCompany).Include(a => a.Site);

return View(assets.ToList());

}

I have swapped out the table code and copied the following from the demo

@(Html.Kendo().Grid(Model)

.Name("Grid")

.Columns(columns =>

{

columns.Bound(p => p.Site).Title("Site").Width(130);

columns.Bound(p => p.Location).Title("Location").Width(130);

columns.Bound(p => p.Description).Title("Decriptopn").Width(130);

columns.Bound(p => p.InstallDate).Title("Install Date").Width(130);

columns.Bound(p => p.SerialNo).Title("Serial Number").Width(130);

})

.Pageable()

.Sortable()

.Scrollable(scr => scr.Height(430))

.Filterable()

.DataSource(dataSource => dataSource

.Ajax()

.PageSize(20)

.ServerOperation(false)

)

When I try to view the

System.InvalidOperationException was unhandled by user code
HResult=-2146233079
Message=A circular reference was detected while serializing an object of type 'System.Data.Entity.DynamicProxies.Asset_ED2530D1AC046011EB9F014D634FE570012E36DD19818476965A4BF61659B91A'.
Source=System.Web.Extensions

I changed the HTML helper line to

@(Html.Kendo().Grid<AMScan.Models.Asset>()

which then rendered the grid on the page without the exception however there was no data.

Can you please tell me what I am doing wrong.

Kendo Grid with filtering on Aggregate Child property

Given the following data model:

     Product
          Id (int)
          Name (string)
          VapourPressure (double)
          Components (IEnumerable<Component>)

      Component
          Id (int)
          Name (string)

I want to create a grid using these that displays the data. In this case Name, VapourPressure, Components. The components should be displayed in a HTML list. Of course I want to be able to filter on the presence of 'components' in the Components.

My current code is attached.

I have got displaying the components working, although I needed a workaround because any '+' characters are stripped from the template parameter. If there is another way to do this I would like to hear it.

What I don't have working is the filtering on components. First of all the drop down doesn't work correctly because the options loaded from AJAX are not shown. If the dropdown is instantiated outside the grid everything works fine. How do I get the dropdown working?

MVC Wrappers cause double AJAX postback in debug mode using Ajax.Beginform()

For anybody who finds this problem, the fix is to add the following line to the bundleconfig.cs file:

bundles.IgnoreList.Ignore("*.unobtrusive-ajax.min.js", OptimizationMode.WhenDisabled);

This will prevent the unobtrusive ajax script from loading twice (i.e. the minified and non-minified) in debug mode, which is what causes the double postback.

Alternatively, just remove the non minified script from the project (this obviously has implications for debugging, if you're inclined to debug the scripts included in the project template).

Telerik - this ought to be included in your how-to guide.

Menu Options Border in Chrome

Hi all. I am testing the menu kendo framework and I am having a issue. In IE 11, late Firefox version and Safari, does not happen, only happens in Google Chrome.

With normal zoom (100%) the menu options seems to be good. But when I set the zoom to 125%, only in some menu items, the lefthand border disappear, even the option top border. It appears again when I set the zoom to 130% or less (120% e.g.).

It also happens when I restore down the window. I send an image with the behaviour.

Anyone had the same problem?
