Missing Localization in ColorPicker

Dear Telerik team.

Would it be possible for you to localize the five messages of the color picker widget?

It is pretty annoying to handle several languages by setting the color picker message option on every usage.

Or tell us what changes in the messages file are needed to have only one place to modify.

Kind regards

Bernd

Databound event firing before Datasource.Read

I understand the Databound event for the MVC grid is supposed to fire after the grid is fully rendered. But I'm seeing the databound event fires, then my read action fires, after which the databound event doesn't fire again. Below is my code for the grid. Anyone have an idea of what I'm doing wrong? Thanks in advance.

@(Html.Kendo().Grid<dynamic>()

.Name("StandardTable_" + Model.InstanceKey)

.Resizable(resize => resize.Columns(true))

.Pageable(pageable => pageable

.Input(true)

.Refresh(true)

.PageSizes(true)

.ButtonCount(5)

.Enabled(true)

.Numeric(false)

).ColumnMenu()

.Sortable(s => s.SortMode(GridSortMode.MultipleColumn).AllowUnsort(true))

.Filterable()

.Groupable()

.Reorderable(reorder => reorder.Columns(true))

.Scrollable(e => e.Enabled(true).Virtual(true).Height("auto"))

.EnableCustomBinding(true)

.Events(e => e

.DataBound("pan.dashboardsetup.gridDatabound(" + Model.dashFeed?.FeedKey + "," + Model.InstanceKey + ")")

.ColumnMenuInit("pan.dashDatapart.menuInit")

)

.DataSource(d => d

.Ajax()

.PageSize(pageSize)

.Read(read => read

.Action("StandardTableRead", "Feeds").Data("pan.dashDatapart.StandardGridRead(" + Model.dashFeed?.FeedKey + "," + Model.InstanceKey + ")")

)

Optional Grouping

I want to perform automatic grouping at run-time under certain conditions. I am currently handling it by attaching to .DataBound event and if a js flag variable is set then I call:

var grid = $("#myGrid").data("kendoGrid");

grid.dataSource.group({ field: "FieldToBeGrouped" });

Is there a more recommended way?

Reason I am asking is I am noticing some oddities when it executes the grouping where it takes longer than expected and results in browser error Uncaught RangeError: Maximum call stack size exceeded. The end result does have the grid grouped as I would expect but the error and execution time is worrisome.

Note the field that is being grouped is listed as Hidden. Also I do not want to give the ability for the user to group other columns (or think that they can) so I have not included .Groupable() in order to not show the grouping toolbar. I did try including .Groupable() and still noticed same issues.

Validation before action execute

We have a dialog where a user needs to select an item from a drop down list. The dialog has an OK and Cancel button. We want to validate the selection when the user clicks OK but not when they click cancel. Is there a way I can do this with actions or is the only alternative to add buttons as content and handle the close on our own?

Thanks,

~Justin

JSON JavascriptSerializer Error with Kendo Editor ASP.NET MVC

Hi,

I use Kendo Editor ASP.NET MVC .

I paste some pictures and I save the content of the editor in my database.

The size of the content is ~20Mo.

Later, when I want to resume the content to modify it, I have the error :

Error during serialization or deserialization using the JSON JavaScriptSerializer. The length of the string exceeds the value set on the maxJsonLength property.

In my web.config file I added a maxJsonLength, but that doesn't change anything

What solution(s) do I have?

Thanks,

Regards

Events are not lining up correctly with day

I am having an issue with Kendo Scheduler where the events are not lining up with their respective days. I am loading events from a SQL Server database. The start date for the first event is coming back as 2/12/2018 12:00:00 AM. I can't find a reason for the offset. See attached image.

MVC Grid and Many-To-Many Relationship

Hello,

I have Many-To-Many Relationship problem in my Grid.Searched the examples but could not find a way to do the column binding (unless using separate ViewModel). What I tried to do is:

columns.Bound(o => o.PERSON.EDUCATIONs.Select(m => m.E_DEGREE)).Title("Degree").Width("12.5%");

That, of course, gives the following error:

Bound columns require a field or property access expression.

Is it possible to achieve the above?

Thanks
