I have a multi select control which allows users to select items, I save the selected items to a database. When the page is next loaded I want to retrieve the list of items from a remote data source but also set the currently selected items.

My code is:

$('#componentList').kendoMultiSelect(
{
autoBind: false,
dataTextField: 'COMPONENT_NAME',
dataValueField: 'COMPONENT_ID',
dataSource: {
transport: {
read: {
url: '/Data/GetData'
dataType: 'json'
}
},
schema: {
data: function (data) { //specify the array that contains the data
return data.fullList;
}
}
});

As you can see my web service returns the data in the field fullList, I also have another field called selectedList on my datasource. How do I set the values from that? Do I have to do a seperate ajax call to get the selected data or can this be done in a single server round trip?

Thanks.

Duplicate Multiple Inserts on Update Insert and Delete commands

The code (nothing wrong with the code)

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

      .Name("MyCourseTypesGrid")

      .Editable(e => e.Mode(GridEditMode.InLine))

      .ToolBar(toolbar => toolbar.Create().Text("New Course"))

      .Columns(columns =>

          {

              columns.Bound(o => o.Title);

              columns.Bound(c => c.IsActive).Width(60);

              columns.Bound(c => c.DotCourse).Width(60);

              columns.Bound(c => c.RenewalInterval).ClientTemplate("#=RenewalInterval# (#=TimeFrame#)").Width(60);

              columns.Bound(c => c.TimeFrame).Width(80);

              columns.Command(command =>

                  {

                      command.Edit();

                      command.Destroy();

                  }).Width(200);

          }).Sortable().Pageable().Groupable()

        .DataSource(datasource => datasource

        .Ajax()

        .Model(p => p.Id(m => m.Id))

        .Create(create => create.Action("InsertCourseType", "Admin"))

        .Read(read => read.Action("CourseTypesGridData", "Admin"))

        .Update(update => update.Action( "UpdateCourseType", "Admin"))

        .Destroy(delete => delete.Action("DeleteCourseType", "Admin"))))

Just posting this because I saw some similar posts that seemed unanswered
I was having some problems in that whenever I updated an item in my grid I was finding new records filling up
my database.
Update the record
During debugging I was seeing that the insert method was being called multiple times instead of the expected update. This was very frustrating.
10 new rows
I noticed that the the number of new phantom rows was equal to the number of records showing on the page.
The solution
It seems that the update or insert for the grid is based on the id being zero. I don't know what this would mean for other types. Anyhow, the problem is that in my viewmodel code I had forgot to copy over the primarykey ids so they were all zero.
The kendo grid
Apparently, decides to do an insert for every PrimaryKey equalling zero. If a non-zero value is there the update method is called.

Your kendo.common.css contains the following declaration

:-webkit-any(body):after {
content: "";
display: block;
visibility: hidden;
height: 0;

-webkit-transform: translateZ(0);
}

The content css property cause a problem in jquery ui dialog - the scrollbar of the dialog are invisible/disapears
If i am removing the content (putting in comment) all works well - scroll bars appears.

Are you familar with such problem? what can be cause by removing the conten:"" css property.

Unable to stop default navigation of tabstrip.

In my application we are showing multiple views under a same tab.
Here I am adding two screenshots to illustrate the case.
Here the active tab has href = [the id of the calendar view].
now from the details(view as shown in details.png) page when I am tapping the calendar icon of the tabstrip(i,e the active tab) it's navigating to the calendar(view as shown in calendar.png) view.
I wanted to stop this navigation, but I am not being able to do so.
I have tried adding jQuery click event on the tabs but it's not firing the click event when its related view is not visible.
Please refer me a way to do that.
Thanks Dave

Drag & Drop: Potential Bug

I believe I have found a bug in the TreeView control. I have produced this in FF & IE latest, within the attachment.

To reproduce:

Expand "outer 6"
Drag "inner 3" over "outer 1" and release
Drag "outer 1" over "inner 2" and release
ISSUE: "inner 3" disappears
ISSUE: try collapsing "inner 2", spinner graphic stays

I'm thinking this has to do with the fact that I started with an existing ul/li structure as it doesn't appear to happen on the demos.

If I'm incorrect here, what is the resolution?

Kendo Grid Filter on a dynamic column

I am working on a Kendo Grid which has a Status column that is an aggregate of statuses of several other columns. I track the individual statuses as integer values and the aggregate column should show the least of the statuses. Now, using template, I am able to render the text for the Status column fine, however, the problem is that I want this column to be filterable. This is not working as the value is calculated.

In DataSource, this is how I have declared the custom field,

schema: {
model: {
Status: function () {
return helper.GetStatus(this.EntriesStatus);
}
}
}

This is how I used it in the Column definition,

{
field: "Status",
title: "Status",
width: "100px",
filterable: true,
template: kendo.template("#if (HasError) {# <strong class='clrRed' > \#= Status() #\ </strong> #} else { # \#= Status() #\ #} #"),
hidden: false,
menu: false
}

Could anyone point out where I am going wrong or a more efficient way out?

[Solved] Widget Display with changed Font Size

When changing a page's font size, the widgets do not display perfectly. Some parts of the widgets are mis-aligned, and other things happen.

For an example, open http://demos.kendoui.com/web/numerictextbox/index.html. Then with Chrome Developer Tools select the first "input type=text" and as the element's style enter a font size of 16px.

The "up/down" buttons will stay at their current location at the top of the span. They should be vertically centered instead.
The border at the left side of the "up/down" buttons is too short. There is a gap at the bottom.

What do you suggest? Is it easily possible to change the font size? Can some "magic" be applied globally? Or has this to be done widget for widget?
