Hello
I am running into a problem using the data field on the transport read. The additionalData function is called only the 1st time the datasource executes read.
I have an event that updates the viewModel and the calls read() on the datasource. I can confirm that it makes a call to the server every time but it only calls additionalData the 1st time.
Here are extracts of the related bits of code.
//in the datasource setup
transport: {
read: {
url: crudServiceBaseUrl + "/NoteSource",
dataType: "json",
data: App.Notes.additionalData(),
cache: false
},
create: {
url: crudServiceBaseUrl + "/Editing_Create",
dataType: "json"
}
}
//in App.Notes
where additionalData is:
additionalData: function () {
console.log("additionalData");
console.log(App.Notes.viewModel.linkedModel());
return { entity: App.Notes.viewModel.linkedModel(), entityId: App.Notes.viewModel.linkedModelId() };
}
in the App.Notes namespace.
and viewModel is:
viewModel: {
linkedModel: ko.observable(""),
linkedModelId: ko.observable(0),
username: ko.observable(""),
noteType: ko.observable(""),
createdAt: ko.observable(new Date())
}
also in the same namespace.
The event handler contains the following that triggers the read and subsequent call to the server:
listView.dataSource.read();
Also just as a side note. This worked when i used the mvc version but I then got a stack overflow when I tried to include a partial of the cshtml page that contains this in my _Layout.
@(Html.Kendo().ListView<TimeTarget.RDM.Core.DataTransferObjects.NoteDto>()
.Name("listView")
.TagName("div")
.ClientTemplateId("template")
.Editable()
.DataSource(dataSource => dataSource
.Model(model => model.Id("NoteId"))
.Create(create => create.Action("Editing_Create", "Note"))
.Read(read => read.Action("NoteSource", "Note")
.Data("App.Notes.additionalData")
) // Specify the action method and controller name
)
.Pageable(paging => paging.Enabled(true))
)

I am developing an MVC 4 website for a customer and have run into an issue with the dropdownlist.
I have a Grid, bound to my model, and I can see all the data (correctly) in the grid.
The above code loads the grid fine, I can trigger all the actions correctly, and they all work great.
My problem comes in when I edit a row, and the field I need to change is a DropDownList. For this particular issue, it is a list of States. We are using popup edit mode, and have a custom editor template.
This is the Editor Template code.
The control successfully loads the states, and binds to the model, and shows the correct state value, if there is one provided. In our database, the StateId field is Nullable, and I think this is where the problems arise.
For completeness, here is the controller function that populates the state list.
the client.GetStates() returns an IEnumerable<State> collection.
NOTE: This exact same code works in a non-grid view in our MVC project.
Now, when the StateId is populated on load, it will display the correct state in the DropDownList. If I change this state and click the Update button on my popup editor, the Update Action is triggered, model.StateId = NewIDSelected and the change gets saved to the database. Now if the StateId is NULL from the database, obviously no state is selected, but now, if I select a state from the DropDownList, and click the Update button on my editor, the Update Action is not triggered, and no change is saved to the database.
To add to that, if I change any other field on the editor (say change or add the street address) in addition to the State change (from null to a state value), the Update Action is correctly triggered, but the model.StateId = null.
As I stated before, this exact same scenario works perfectly on a view that does not use a grid at all (as a matter of fact the popup editor is an exact duplicate of that view).
Can anyone help me figure out how to fix this? We have got around it by using a plain HTML DropDownList, but it is ugly ugly... but it works.

Hey everyone!
I was searching all over but couldn't find an answer to my question. I'm initializing an autocomplete widget as the following:
This code is loaded into my DOM as a result of an Ajax request:

However, the autocomplete search works perfect. But now I want to populate the fields jtc_cMail and jtc_cPhone with values from my autocomplete request. But either the select: Function is working (not allowed here (guess because MVVM?), also the custom event inject is fireing.

Hello Support:
I'm having conceptual difficulties with how to encapsulate a fetch(). Consider the following:
var getAllProjects = function() {
projectsDataSource.fetch(function() {
var dataView = projectsDataSource.view();
return dataView;
});
};
where projectsDataSource is a Kendo dataSource defined with a remote source. I should say that the inner portion above works flawlessly (by inner portion I mean the part defined as projectsDataSource.fetch(function() { ...}).
However, I decided to encapsulate this functionality in a separate module defined by RequireJS, leading naively to the code above where I declare getAllProjects().
I'm trying to return dataView to the outer function, getAllProjects(), a function that is revealed publicly. All I get back, though, is undefined. It would seem that you're using callbacks, not promises, which appears to be confusing me.
What am I missing here?
Thank you.

I am using Kendo dataSource with transport (read, update, create) functionality. read operation retrieves data and displays it in a Grid. Gird has 3 columns - key, value, and class. Update operation edits a particular row taking in the options object as shown -
parameterMap : function (options, operation) {
if (operation == "update") {
return {key : options.models[0].key, value : options.models[0].value, class : options.models[0].class}
}
}
The options object above is pre-loaded with the data in the particular row of the grid being edited.
However, for create operation, the options object is pre-set to null for all the fields. Options object is loaded when the user enters values for key and value. The value of class remains the same for all the rows, existing and new. How can I access the grid data (for the value of class) within the the code below?
parameterMap : function (options, operation) {
if (operation == "update") {
return {key : options.models[0].key, value : options.models[0].value, class : options.models[0].class}
}
if (operation == "create") {
return {key : options.models[0].key, value : options.models[0].value, class : <what code should go here?>}
}
}
parameterMap : function (options, operation) {
if (operation == "update") {
return {key : options.models[0].key, value : options.models[0].value, class : options.models[0].class}
}
}

I have a grid with a details template (i.e outer grid with an inner grid).
My outer grid has "Create" functionality. When I add a new row I am able to expand the inner grid before saving, and this causes an error in the backend, because the new row is not saved and does not have an id yet.
Is there a way to disable the details (inner grid expansion) for a new row?

Hi,
Just to let you know that API Reference at http://docs.kendoui.com/api/web/upload#configuration-async.removeField says:
async.removeVerb String(default: "DELETE")
but by default POST is used and async.removeUrl is stating that server method should support POST.
Best regards
