I am using the following menu

$("#settingsmenu").kendoMenu({
dataSource: [{
text: 'Settings',
items: settingOptions
}],
openOnClick: true,
closeOnClick: false,
open: function () {
/...../
},
select: function () {
/..../
}
});

Following is my menu
<ul id="settingsmenu" class="pull-right">
<li>
<span class="glyphicon glyphicon-cog"></span>
</li>
</ul>

Now what is get is a down arrow next to settings text.
I need to show a bootstrap glyph icon(a span essentially).
Any way that I can achieve this ?

Grid Foreign Key Field sometime shows textbox

Hi

I have multiple kendo grid used inside a kendo tabstrip. I have same model for all the grid with some filter criteria.

Everything seems to be working fine except when i add or edit one grid and at the same time try to edit another grid, its foreign key is not showing its template. It shows textbox instead of dropdown.

Is this a known bug or is there any idea how to resolve this?

Regards
Victor

Listview Selection

Hello,
I have a Telerik ListView inside a partial view that is rendered inside a kendo Window in modal mode. Using MVC5.

The listview is setup to query the controller for records (which are image files).

In the edit view for my model, and the user can select an image to be part of the model's data. I want them to select from maybe 5000 images on our system. So the Listview popup starts with 6 visible images (pagesize is 6) and they can cycle via paging to the image they want to select.

This all works fine.

Currently when the listbox is displayed, (after a button click on view), it always shows the very first 6. Consider case where user is editing record 10, and that record has already specified it uses pictureId 50 (pictureID is foreign key to picture table). I want the listbox to show Item 50 in its selected page, but allow the user to page back to other pages, or page forward. The page backs/forwards will do the datarequests as needed.

I added a "save" button to the popup window so i could test out code. My listview is named "imageListView".
In my sample, i just wanted to choose item 9, as an example.
If i first navigate to page 2 so item 9 is shown on the listview, then the below code works fine.
but if i am on page 1 (items 1-6 shown), the get(9) call returns null.

how can i figure out what page to go to prior to actually loading the items on the page?

$("#save").click(function () {

var lv = $("#imageListView").data("kendoListView");

var model = lv.dataSource.get(9);

var index = lv.dataSource.indexOf(model);

var pg = Math.floor(index / lv.dataSource.pageSize()) + 1;

lv.dataSource.page(pg);

}

Initialize Grid Options from Serialized JSON String

We allow our users to optionally save the state of their grids and persist them in the db. When a user comes back to he screen, they see the standard grid display just for a moment, then it updates their grid via JavaScript ( setOptions call) as it applies their persisted state settings. This makes it look like it's doing a double load.

We would rather just initialize the grid with their persisted settings (via serialized json string) so the grid shows correctly on the initial load.

Is this possible?

We are using MVC.

Thanks!

ColorPicker in Editor Template

Hello,

I have an editable grid which is set up to use PopUp edit mode. One of the columns (color) is a string that holds a hex value for a color. I have created an editor template to handle the edit and create functions. Here is how I define the grid:

@(Html.Kendo().Grid<DL.Data.PayCodes>()

.Name("grdPayCodes")

.Columns(columns =>

{

columns.Bound(p => p.pay_code).Width(120).Title("Code");

columns.Bound(p => p.color).Width(75).Title("Color").ClientTemplate("<div style='width: 100%; text-align: center;'><div style=

'width: 25px; height: 25px; background: #=color#; -moz-border-radius: 17px; -webkit-border-radius: 17px; border-radius: 17px; margin: auto; #= SetBorder(this, color)#'

></div></div>");

columns.Bound(p => p.description).Title("Description");

columns.Command(command => { command.Edit(); command.Custom("Delete").Click("DeletePayCodes_Click"); }).Width(180).HtmlAttributes(new { style = "text-align: center;" });

})

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

.Editable(editable => editable.Mode(GridEditMode.PopUp).TemplateName("PayCodesAddRecordTemplate"))

.Sortable()

.Scrollable()

.HtmlAttributes(new { style = "height:430px; margin-top: 7px;" })

.DataSource(dataSource => dataSource

.Ajax()

.Model(model => model.Id(p => p.pay_code))

.Create(update => update.Action("CreatePayCodes", "Settings"))

.Read(read => read.Action("GetPayCodesDSGrid", "Common"))

.Update(update => update.Action("UpdatePayCodes", "Settings"))

.Events(events => events.Error("grdPayCodes_ErrorHandler").RequestEnd("grdPayCodes_RequestEnd"))

)

.Events(ev => ev.DataBound("grdPayCodes_DataBound").Edit("grdPayCodes_Edit"))

)

and here is how I define my editor template

<table style="margin-left: 5%; width: 90%;">

<tr>

<td class="label-cell">

<label for="pay_code">Code</label>

</td>

<td>

<input id="pay_code" name="pit_name" class="data-cell" data-bind="value: pay_code">

</td>

</tr>

<tr>

<td class="label-cell">

<label for="color">Color</label>

</td>

<td>

@(Html.Kendo().ColorPicker()

.Name("color")

.Value("#ffffff")

)

</td>

</tr>

<tr>

<td class="label-cell">

<label for="description">Description</label>

</td>

<td>

<input id="description" name="description" class="data-cell" data-bind="value: description">

</td>

</tr>

</table>

Everything works well for the edit, however when I try to create a new record, I get an error: Cannot Parse Color: at kendo.all.min.js, line 17, column 6374

I understand that when creating a new record the color property of the model is an empty string, but I am initializing the color picker with a default value of #ffffff. Why am I still getting this error?

I am using version 2013.3.1119.340 with VS 2013. I am testing on IE 11, but I tried FF and I am still getting the same error.

Any help would be greatly appreciated.

Thank you.

Common configuration

For the majority of our grids we have a specific configuration, Paging, Filters, etc. Any ideas of how to create a single config object in C# that I can just pass into a grid rather than setting everything for every grid.

With js it seems doable... I just create a config object, modify any of our defaults if needs for that grid, and pass it to the jQuery extension.

But, I'm not sure how to do it for the MVC helpers. Any ideas?

DropDown in Grid

I was following the demo for the Custom Editting
http://demos.telerik.com/aspnet-mvc/grid/editing-custom

And I did not get the Drop down as expected. I saw the ID and Name be replace in the column instead a drop down

I used the
Columns.Bound(p => p.Category).ClientTemplate("#=Category.CategoryName#").Width(160);

The one thing I couldnt not figure out was in the Controller it defince the ViewData["categories"] = categories;

I could not figure out how that was wired to the Razor page.

I am using kendo button the following way.

@(Html.Kendo().Button().Name("deleteButton").HtmlAttributes(new { type = "button", @class = "k-primary pull-right" }).Content("Delete").Events(ev => ev.Click("Delete(1)")))

I need to call a javascript function with parameters

But it doesn't work when I click the button.
Everything works fine without arguments.

Does telerik support passing arguments to javascript functions from buttons?
